Toxicity of dorsal root ganglia is widely associated with CNS AAV gene therapy – Science Codex

New Rochelle, NY, September 2, 2020A meta-analysis of non-human primate (NHP) studies showed that adeno-associated virus (AAV) gene therapy often caused dorsal root ganglion (DRG) pathology. There were no clinical effects. The study is reported in the peer-reviewed journal Human Gene Therapy.Click here to read the full-text article free on the Human Gene Therapy website through October 2, 2020.

The dorsal root ganglion is a cluster of neurons in the dorsal root of a spinal nerve. DRG pathology was present in 83% of NHP given AAV through the cerebrospinal fluid and 32% of NHP that received an intravenous injection.

The data suggest that DRG pathology is almost universal after AAV vectors are delivered into the cerebral spinal fluid of nonhuman primates. However, none of the animals receiving a vector expressing a therapeutic transgene displayed any clinical signs, stated James M. Wilson, MD, PhD, a professor of Medicine and director of the Gene Therapy Program and the Orphan Disease Center, and coauthors from the Perelman School of Medicine at the University of Pennsylvania.

The DRG pathology associated with AAV has triggered an increase in the intensity of preclinical evaluation of AAV vectors prior to initiation of clinical trials of new vectors, according to Editor-in-Chief of Human Gene Therapy Terence R. Flotte, MD, Celia and Isaac Haidak Professor of Medical Education and Dean, Provost, and Executive Deputy Chancellor, University of Massachusetts Medical School. The insights offered by Dr. Wilsons paper provide an excellent summary perspective on this phenomenon, which could potentially eliminate the need for a number of redundant preclinical safety studies and thus shorten the path to the clinic for new vectors.

Cell Suicide Gene Further Linked to Immunotherapy Response – Technology Networks

Johns Hopkins Medicine researchers have added to evidence that a gene responsible for turning off a cells natural suicide signals may also be the culprit in making breast cancer and melanoma cells resistant to therapies that use the immune system to fight cancer. A summary of the research, conducted with mice and human cells, appeared in Cell Reports.When the gene, called BIRC2, is sent into overdrive, it makes too much, or an overexpression, of protein levels. This occurs in about 40% of breast cancers, particularly the more lethal type called triple negative, and it is not known how often the gene is overexpressed in melanomas.

If further studies affirm and refine the new findings, the researchers say, BIRC2 overexpression could be a key marker for immunotherapy resistance, further advancing precision medicine efforts in this area of cancer treatment. A marker of this kind could alert clinicians to the potential need for using drugs that block the genes activity in combination with immunotherapy drugs to form a potent cocktail to kill cancer in some treatment-resistant patients. Cancer cells use many pathways to evade the immune system, so our goal is to find additional drugs in our toolbox to complement the immunotherapy drugs currently in use, says Gregg Semenza, M.D., Ph.D., the C. Michael Armstrong Professor of Genetic Medicine, Pediatrics, Oncology, Medicine, Radiation Oncology and Biological Chemistry at the Johns Hopkins University School of Medicine, and director of the Vascular Program at the Johns Hopkins Institute for Cell Engineering.

Semenza shared the 2019 Nobel Prize in Physiology or Medicine for the discovery of the gene that guides how cells adapt to low oxygen levels, a condition called hypoxia.

In 2018, Semenzas team showed that hypoxia essentially molds cancer cells into survival machines. Hypoxia prompts cancer cells to turn on three genes to help them evade the immune system by inactivating either the identification system or the eat me signal on immune cells. A cell surface protein called CD47 is the only dont eat me signal that blocks killing of cancer cells by immune cells called macrophages. Other cell surface proteins, PDL1 and CD73, block killing of cancer cells by immune cells called T lymphocytes.

These super-survivor cancer cells could explain, in part, Semenza says, why only 20% to 30% of cancer patients respond to drugs that boost the immune systems ability to target cancer cells.

For the current study, building on his basic science discoveries, Semenza and his team sorted through 325 human genes identified by researchers at the Dana Farber Cancer Institute in Boston whose protein products were overexpressed in melanoma cells and linked to processes that help cancer cells evade the immune system.

Semenzas team found that 38 of the genes are influenced by the transcription factor HIF-1, which regulates how cells adapt to hypoxia; among the 38 was BIRC2 (baculoviral IAP repeat-containing 2), already known to prevent cell suicide, or apoptosis, in essence a form of programmed cell death that is a brake on the kind of unchecked cell growth characteristic of cancer.

BIRC2 also blocks cells from secreting proteins that attract immune cells, such as T-cells and natural killer cells.

First, by studying the BIRC2 genome in human breast cancer cells, Semenzas team found that hypoxia proteins HIF1 and HIF2 bind directly to a portion of the BIRC2 gene under low oxygen conditions, identifying a direct mechanism for boosting the BIRC2 genes protein production.

Then, the research team examined how tumors developed in mice when they were injected with human breast cancer or melanoma cells genetically engineered to contain little or no BIRC2 gene expression. In mice injected with cancer cells lacking BIRC2 expression, tumors took longer to form, about three to four weeks, compared with the typical two weeks it takes to form tumors in mice.

The tumors formed by BIRC2-free cancer cells also had up to five times the level of a protein called CXCL9, the substance that attracts immune system T-cells and natural killer cells to the tumor location. The longer the tumor took to form, the more T-cells and natural killer cells were found inside the tumor.

Semenza notes that finding a plentiful number of immune cells within a tumor is a key indicator of immunotherapy success.

Next, to determine whether the immune system was critical to the stalled tumor growth they saw, Semenzas team injected the BIRC2-free melanoma and breast cancer cells into mice bred to have no functioning immune system. They found that tumors grew at the same rate, in about two weeks, as typical tumors. This suggests that the decreased tumor growth rate associated with loss of BIRC2 is dependent on recruiting T-cells and natural killer cells into the tumor, says Semenza.

Finally, Semenza and his team analyzed mice implanted with human breast cancer or melanoma tumors that either produced BIRC2 or were engineered to lack BIRC2. They gave the mice with melanoma tumors two types of immunotherapy FDA-approved for human use, and treated mice with breast tumors with one of the immunotherapy drugs. In both tumor types, the immunotherapy drugs were effective only against the tumors that lacked BIRC2.

Experimental drugs called SMAC mimetics that inactivate BIRC2 and other anti-cell suicide proteins are currently in clinical trials for certain types of cancers, but Semenza says that the drugs have not been very effective when used on their own.

These drugs might be very useful to improve the response to immunotherapy drugs in people with tumors that have high BIRC2 levels, says Semenza.Reference: Samanta D, Huang TYT, Shah R, Yang Y, Pan F, Semenza GL.

Cats point the way to potential COVID-19 remedies – FierceBiotech

Last week, Gilead Sciences said it would test its COVID-19 drug remdesivir against a related compound in its library called GS-441524 in animal trials, after facing scrutiny over the latter drug, which has been used for years to treat feline infectious peritonitis (FIP) despite not being licensed for that use.

Now, another California biotech, Anivive Lifesciences, is working on a COVID-19 antiviral drug thats inspired by cats, and it has new preclinical research findings to back up the project.

Scientists led by the University of Alberta reported that a drug developed to treat a coronavirus that can cause FIP inhibited the main protease of both SARS-CoV and SARS-CoV-2. That prevented the human coronaviruses from replicating in cell cultures, they reported in the journal Nature Communications.

Overcoming Scalability Challenges with Autologous Therapies

Catalent presents a clinical-to-commercial perspective on autologous therapies. Join experts Prof. Gerhard Bauer and Catalents Dr. James Crutchley as they discuss challenges and an innovative methodology to commercially scale autologous therapies.

Anivive originally licensed the drug, called GC376, from Kansas State University in 2018 and has been working since then to develop it as an antiviral to treat FIP, a progressive disease in cats thats often caused by a coronavirus and is fatal if left untreated. Last month, Anivive said it had started two preclinical studies to determine whether GC376 could also treat COVID-19.

RELATED: COVID-19: New animal data back up Gilead's remdesivir as other treatment candidates emerge

GC376 was designed to inhibit a protease called 3C, which promotes the replication of several coronaviruses that infect animals and people. They include feline coronavirus (FCoV), which usually causes mild symptoms in cats but can lead to FIP.

Two pilot studies of GC376 in pet cats infected with FIP showed that the drug was effective against the disease within two weeks and was well tolerated. Anivive is currently scaling up production of the drug for larger studies in cats.

For the new study, the University of Alberta team tested both GC376 and its parent drug, GC373, for their ability to inhibit the 3C protease. Both drugs blocked viral replication, they reported.

The authors acknowledged that vaccines against COVID-19 are advancing rapidly, but they suggested antiviral drugs are still necessary in the short term. SARS-CoV-2 is a virus with a significant mutation rate. Also, in some patients the virus has persisted longer than 2 months with some possibility of re-infection, they wrote in the study.

M. Joanne Lemieux, Ph.D., professor of structural biology at the University of Alberta, pointed out in an interview with Genetic Engineering & Biotechnology News that GC376 could be advanced rapidly into human trials, given its track record in veterinary medicine.

Because this drug has already been used to treat cats with coronavirus, and its effective with little to no toxicity, its already passed [preclinical] stages, and this allows us to move forward, Lemieux said.

Is Lab-Grown Meat Healthy and Safe to Consume? – One Green Planet

It goes by many names: cultured, in vitro, cell-based, cultivated, lab-grown meat, etc. As the names imply, it is a meat alternative made in a lab via animal cells and a cultured medium, like fetal bovine serum or a proprietary mix of sugars and salts. Several companies around the world are promoting this new technique as a way to cultivate a meat alternative that is supposedly cleaner and safer than traditional meat.

(We are only looking at those products that culture cells taken from animals into a new meat-like formulation. There are many other products that culture plant, fungi, or algal cells into a meat substitute, but we are not reviewing them here.)

29 companies are planning to bring lab-cultured meat to market in the form of chicken, beef, pork, seafood, pet food, and beyond. These companies include Memphis Meats, Aleph Farms, Mosa Meat, Meatable, SuperMeat, and Finless Foods. These companies are backed by huge investments from meat industry corporations (Cargill and Tyson), venture capitalist firms (Blue Yard Capital, Union Square Ventures, S2G Ventures, and Emerald Technology Ventures), and billionaires (such as Bill Gates and Richard Branson).

While the hype is certainly there, is lab-cultured meat actually better? Its proponents tout it as an environmentally responsible, cruelty-free, and antibiotic-free alternative to current meat production. While the goal of producing sustainable meat without killing animals is admirable, lab-cultured meat is in its infancy and the science behind the production methods requires more scrutiny.

Of particular concern is the genetic engineering of cells and their potential cancer-promoting properties. To be able to better assess whether the products are being produced by methods that involve genetic engineering and use genetic constructs (called onco-genes, typically used to make stem cells keep growing; this is not a problem for lab experiments, but could be for food products) that might encourage cancer cells, we need more information on how the cells are engineered and kept growing. Many of the companies are claiming this information is confidential and a business secret. These companies are not yet patenting their production processes wherein this information would be more fully disclosed. Some suggest that the production will follow the FDA cell culture guidelines, but theFDAs cell culture guidelines do not apply to this because theyre not designed for food.

To produce lab-cultured meat, many producers extract animal cells from living animals. This is typically done via biopsy, a painful and uncomfortable procedure that uses large needles. If a company could scale up with this method, it would require a consistent supply of animals from which to acquire cells and innumerable painful extractions. To make the cell-based product more consistent, the producer may biopsy the same animal many times for the cells that growing meat requires.

Growing animal cells (typically muscle cells) also requires a growth medium. When lab-cultured meat production first began, companies depended on fetal bovine serum (FBS) as a growth medium. Producing FBS involves extracting blood from the fetus of a pregnant cow when the cow is slaughtered.

Given its high cost, it appears that FBS is usually only used during small-scale lab trials. Additionally, increasing production capacity using FBS comes with its own set of concerns. Even disregarding the high cost of FBS, non-genetically engineered animal muscle cells only proliferate or increase to a certain degree. In order to overcome this limitation, large companies such as Mosa Meats and Memphis Meats claim theyve found an FBS alternative that does not involve animals along with an effective way to expand production. For Memphis Meats, this process involves the utilization of abioreactor and the creation of immortal cell lines.

These companies are using a bioreactor essentially a very large vessel for containing biological reactions and processes to implement a scaffold-based system to grow meat, which uses a specific structure for cells to grow on and around. The scaffolding helps the cells differentiate into a specific meat-like formation. Researchers cite using cornstarch fibers, plant skeletons, fungi, and gelatin as common scaffold materials. Instead of animal muscle cell precursors (otherwise known as myosatellites), researchers have been using cultured stem cells. This distinction is important because extracted muscle cells will only proliferate to a certain extent. Companies are trying cultured stem cells as an alternative type of cell(s) that could proliferate exponentially so that they could scale up production, and later differentiate the cells into the various cell types that make up animal meat (muscle, fat, and blood cells) in a bioreactor.

In this process, the stem cells still come from animals or animal embryos, but what differentiates the two methods is that in the scaffold-based system, the cells can be genetically engineered to proliferate indefinitely. These cells are otherwise known as pluripotent (which make many kinds of cells, like stem cells) or totipotent (which make every kind of cell, as do embryos). This would greatly expand a companys capacity to make lab-cultured meat, but the methods by which companies make these cells proliferate come with human health and food safety ramifications.

While the FDA has previously reviewed enzymes, oils, algal, fungal, and bacterial products grown in microorganisms, these new animal cell-cultured products are much more complicated in structure and require a more thorough review. The scale required for making lab-cultured meat feasible for mass consumption will be the largest form of tissue engineering to exist and could introduce new kinds of genetically engineered cells into our diets. Further research will also be needed to conrm or dispel uncertainties over various potential safety issues. Candidate topics for research include the safety of ingesting rapidly growing genetically-modied cell lines, as these lines exhibit the characteristics of a cancerous cell which include overgrowth of cells not attributed to the original characteristics of a population of cultured primary cells. If lab-cultured meat enters the market, there are several human health concerns associated with this new production method, specifically that these genetically-modified cell lines could exhibit the characteristics of a cancerous cell.

While these companies dont disclose much to the public about their processing methods, their public patents reveal the creation of oncogenic, or cancer-causing, cells.A Memphis Meats patent on the creation of modified pluripotent cell lines involves the activation or inactivation of various proteins responsible for tumor suppression. Another patent from JUST Inc. describes the utilization of growth factors as part of its growth medium. This process could promote the development of cancer-like cells in lab-cultured meat products. Additionally, it is possible certain growth factors can be absorbed in the bloodstream after digestion.

If they are using stem cells, cell-based meat companies need to pay attention to the risk of cancer cells emerging in their cultures. A research team from the Harvard Stem Cell Institute (HSCI), Harvard Medical School (HMS), and the Stanley Center for Psychiatric Research at the Broad Institute of MIT and Harvard has found that as stem cell lines grow in a lab environment, they often acquire mutations in the TP53 (p53) gene, an important tumor suppressor responsible for controlling cell growth and division. Their research suggests that inexpensive genetic sequencing technologies should be used by cell-based meat companies to screen for mutated cells in stem cell cultures so that these cultures can be excluded.

Cancer-causing additives are prohibited in our food supply under the Delaney Clauses in the 19
58 Food Additive Amendments and the 1960 Color Additive Amendments to the Federal Food, Drug, and Cosmetic Act (FFDCA). These new rapidly growing cell lines might be considered color additives if they are being used to produce the color in the meat. The federal statutes regulating meat also prohibit the selling of animals with symptoms of illness, such as cancerous cells in meat. Regardless, all of these new ways of making cells that continue to grow or differentiate should require a safety assessment to determine if they contain cancerous cells before they can be sold.

In describing the scaffolding and growth media being used, lab-cultured meat companies need to be fully transparent about what ingredients theyre using. During the above-mentioned industry nonprofits presentation, the presenter suggested the growth media could be composed of a variety of different ingredients like proteins, amino acids, vitamins, and inorganic salts classified under the GRAS (Generally Recognized As Safe) process that allows companies to do their own testing and not submit to a new FDA food additive review. Since companies are not required to fully disclose the composition of their scaffolding or growth media, potentially exposing consumers to novel proteins and allergens, the new mixture of ingredients should be reviewed under a full FDA supervised food additive review, not GRAS.

Another major issue associated with processing methods using cell lines and/or culture medium is contamination. Unlike animals, cells do not have a fully functioning immune system, so there is a high likelihood of bacterial or fungal growth, mycoplasma, and other human pathogens growing in vats of cells. While lab-cultured meat companies emphasize that this type of meat production would be more sterile than traditional animal agriculture, its unknown how that is true without the use of antibiotics or some other pharmaceutical means of pathogenic control.

Based on commentary from various companies, antibiotic usage across the industry is still very unclear. While the industrys promoters have outlined many uses for antibiotics in lab-grown meat production in preventing contamination, they have not disclosed the amount of antibiotics being used in the various processes. Instead, they suggest that because mass production of lab-grown meat will be done in an industrial rather than lab setting, with bioreactors and tanks, there will be higher safety oversight than in medical labs. It is suggested that the many preventative measures in the industry will maintain a sterile boundary and deter antibiotic use in production. It remains a question of how a food production plant would be more sterile than a medical lab.

Some companies, such as Memphis Meats claim they are genetically engineering cell lines to be antibiotic-resistant, which would suggest they plan on using antibiotics, but dont want their meat cells to be affected. Problems with bacterial and viral contamination plague medical cell culture, so they generally use antimicrobials. Still, any large-scale production that requires antibiotic use even if just for a short-term duration should require such lab-cultured meat undergo even stricter USDA drug residue testing, pathogen testing, and FDA tolerance requirements than conventionally-produced meat. Many other companies claim they dont plan to use antibiotics in expanded production which begs the question, in addition to supposed sterile bioreactors, are they using other undisclosed processes to prevent contamination? For example, Future Meat Technologies describes the use of a special resin to remove toxins.

The companies have also not disclosed plans for how they will dispose of the toxins from bioreactors, scaffolding, and culture media like growth factors/hormones, differentiation factors, often including fetal calf serum or horse serum, and antimicrobials (commonly added to cultured cells to prevent bacterial and fungal contamination, particularly in long-term cultures). In conventionally-produced meat, animals dispose of these toxins in their urine and feces. If companies cant find a way for this meat to dispose of these toxins, they could potentially build up within the meat itself. Given the lack of clarity of these companies and their processes, there must be continuous monitoring of the cell lines and growth media/bioreactor for contaminants and some sort of standardization established across the industry to ensure safety.

The industry is new and the exact production process and inputs needed for large-scale, lab-cultured meat production are unknown (or not being disclosed by the companies). It is the responsibility of both FDA and USDA to ensure that all inputs used in production and the final product are safe for human and animal consumption. These agencies must ensure that lab-cultured meat is labeled appropriately, including if any of the product ingredients are genetically modified or if the ingredients are produced using unmodified cells from animals. These agencies must also ensure that this product doesnt introduce new allergens into the food supply, that any hormones or antibiotics used are not found at unsafe levels in the final product, and that the product doesnt contain any compounds or oncogenic (cancer-causing) cells that have not been approved for use in food.

Lab-cultured meat should not be allowed to use the Generally Recognized As Safe (GRAS) regulatory loophole wherein companies can hire their own experts to evaluate their products, often in secret without any notice to the public or FDA. GRAS is an inappropriate designation because the consensus among knowledgeable experts regarding the safety of lab-cultured meat does not yet exist. Instead, FDA should require that lab-cultured meat products be regulated more thoroughly as food additives. Meat companies should submit complete food additive petitions for each of the novel ingredients used to produce these meats as well as a final food approval petition for the entire product. The production facilities, like all meat processing plants, should then have USDA inspectors on-site monitoring the process and inspecting the meat. The USDA announced in August that it will start the process of developing regulations for these new kinds of meat. Adequate regulation will be necessary to address the concerns raised in this blog.

Overall, due to the novel nature of lab-cultured meat, the lack of transparency from the companies involved, and the myriad potential health risks to consumers, rigorous regulation of this product is vitally important.

Celyad’s High Hopes for a Path Forward in Cancer Immunotherapy with CYAD-211 – BioSpace

Celyad Oncology is at the forefront of cutting-edge immunotherapy and is hopeful of providing a new way forward for patients with relapsed/refractory multiple myeloma. After receiving FDA approval on July 14th to begin Phase I trials, they plan to be in the clinic with their first patient the end of 2020.

The Belgian clinical-stage biotechnology company is focused on the discovery and development of chimeric antigen receptor T cell (CAR-T) therapies for cancer. Celyad Oncology is also developing CYAD-101, an investigational non-gene edited, allogeneic NKG2D-based CAR-T therapy for metastatic colorectal cancer.

The two primary types of cell therapy are autologous and allogeneic. Autologous CAR-T therapy uses the transplantation and genetic editing of a patients own immune cells in a single batch, while an allogeneic transplant uses immune cells from a donor manufactured in large batches. Celyad Oncology is only the fourth company to proceed to Phase I with an allogeneic CAR-T working against a target known as B-cell maturationantigen (BCMA), which is highly expressed in multiple myeloma patients.

The Phase I objectives for CYAD-211 are to establish the viability, effectiveness and further possibilities opened up by the shRNA-based technology. Along with analyzing the merits of targeting BCMA with a CAR-T, Celyad Oncology Chief Executive Officer Filippo Petti shared that the companys first priority is to prove the premise that ShRNA bears out for allogeneic CAR-T.

The first level is to get into the clinic and evaluate the question, is shRNA a novel, non-gene edited allogeneic approach to CAR-T? Where the majority of our peers in the space work on genome using the gene editing technology, if we can show that another non-gene editing technology like ShRNA works, it would just open up the whole field in terms of allogeneic CAR-T. It would demonstrate that we have an unencumbered asset and technology platform for us to create next-generation CAR-T candidates with, Petti said. Well know very quickly, within the first few patients, if we are seeing an absence of graft-versus-host disease, and if ShRNA carries its weight in terms of being an allogeneic technology.

He expects to have a sense of how competitive the data is in terms of both safety and clinical efficacy by end of year 2021.

Dr. Laurence Cooper, Chief Executive Officer (CEO) of Ziopharm Oncology, who is also a veteran innovator in pairing genetic engineering with immunotherapies, explained that Graft-versus-Host Disease (GvHD) is one of biggest challenges facing companies who take the allogeneic approach.

When you put in third party cells, those cells get really confused right off the bat because now theyre somewhere new, and all of a sudden they perceive the patient as the threat. This can result in Graft-versus-Host Disease, an autoimmune disease triggered by the native biology in the T cell through its T cell receptor, Cooper said. The engineering that youre talking about is to eliminate that threat. Some cut out the genetic material coding for the endogenous T cell receptor so that now a T cell can go into another person, and it cant perceive the threat anymore because its lost its antennae. Another way is to prevent expression of the T cell receptor. Now the T cell can do something useful if you put in a CAR, it can go off and targetBCMA.

Frdric F. Lehmann, Head of the Oncology Franchise at Celyad Oncology, explained how the shRNA-based therapy is engineered to reign in the cells new rampant disregard for threat, and lessen the chances of an autoimmune response.

One of the innovations for CYAD-211 is incorporating in the vector a short hairpin RNA (shRNA) targeting the CD3 subunit of the T cell Receptor (TCR). This effectively downregulates the surface expression of the TCR thereby inhibiting the signaling that would lead to Graft-versus-Host Disease, Lehmann said.

A notable drawback with the autologous approach to CAR-T therapy is that it is costly and time-consuming. Petti explained how CYAD-211 not only has the potential to improve efficacy, but also make the treatment process more scalable and therefore economically expedient.

When it comes to commercialization, because we use an all-in-one-vector approach, we benefit from less manipulations during manufacturing, allowing us to enrich for the engineered cells we want, which eventually could help during potential commercialization of a product thats streamlined, Petti said.

He added that the all-in-one vector approach increases efficiency because, as opposed to the case with the gene editing process, they are able to accomplish everything in a single step.

Long term, Cooper is excited about the possibility that, whether autologous or allogeneic, immunotherapy may one day replace bone marrow transplants, or even chemotherapy, but emphasized that it must be made accessible.

If these immunotherapies can be advanced really to replace chemotherapy, not to replace transplantation for liquid tumors, but to replace chemotherapy, which is a huge goal if you can get it to do that, you have to bring the costs down to make it available for the masses, inside first world economies as well as less privileged societies, Cooper said.

In 2013, the overall five-year survival rate for multiple myeloma stood at 49.6%. Relapsed/refractory patients for whom currently available treatments have failed, are the intended beneficiaries of much of the biotechnology work being done in this area. And impressive steps have recently been made.

GlaxoSmithKlines BLENREP (BelantamabMafodotin) is the first in its class to work against BCMA, while Janssen Biotechs (Johnson & Johnson) DARZALEX (Daratumumab) is the first human Anti-CD38 monoclonal antibody in the space. After their 2019 acquisition of Celgene Corp., Bristol-Myers Squibb gained Revlimid (Lenalidomide), a hematology drug approved for multiple myeloma, and Amgen and Takeda have popular proteasome inhibitors on the market.

With Celyad Oncology moving the needle forward once again, the future looks a little brighter for multiple myeloma patients.

Effective Cancer Immunotherapy Further Linked To Regulating A Cell Suicide Gene – Newswise

Newswise Johns Hopkins Medicine researchers have added to evidence that a gene responsible for turning off a cells natural suicide signals may also be the culprit in making breast cancer and melanoma cells resistant to therapies that use the immune system to fight cancer. A summary of the research, conducted with mice and human cells, appeared Aug. 25 in Cell Reports.

When the gene, called BIRC2, is sent into overdrive, it makes too much, or an overexpression, of protein levels. This occurs in about 40% of breast cancers, particularly the more lethal type called triple negative, and it is not known how often the gene is overexpressed in melanomas.

If further studies affirm and refine the new findings, the researchers say, BIRC2 overexpression could be a key marker for immunotherapy resistance, further advancing precision medicine efforts in this area of cancer treatment. A marker of this kind could alert clinicians to the potential need for using drugs that block the genes activity in combination with immunotherapy drugs to form a potent cocktail to kill cancer in some treatment-resistant patients.

Cancer cells use many pathways to evade the immune system, so our goal is to find additional drugs in our toolbox to complement the immunotherapy drugs currently in use, says Gregg Semenza, M.D., Ph.D., the C. Michael Armstrong Professor of Genetic Medicine, Pediatrics, Oncology, Medicine, Radiation Oncology and Biological Chemistry at the Johns Hopkins University School of Medicine, and director of the Vascular Program at the Johns Hopkins Institute for Cell Engineering.

Semenza shared the 2019 Nobel Prize in Physiology or Medicine for the discovery of the gene that guides how cells adapt to low oxygen levels, a condition called hypoxia.

In 2018, Semenzas team showed that hypoxia essentially molds cancer cells into survival machines. Hypoxia prompts cancer cells to turn on three genes to help them evade the immune system by inactivating either the identification system or the eat me signal on immune cells. A cell surface protein called CD47 is the only dont eat me signal that blocks killing of cancer cells by immune cells called macrophages. Other cell surface proteins, PDL1 and CD73, block killing of cancer cells by immune cells called T lymphocytes.

These super-survivor cancer cells could explain, in part, Semenza says, why only 20% to 30% of cancer patients respond to drugs that boost the immune systems ability to target cancer cells.

For the current study, building on his basic science discoveries, Semenza and his team sorted through 325 human genes identified by researchers at the Dana Farber Cancer Institute in Boston whose protein products were overexpressed in melanoma cells and linked to processes that help cancer cells evade the immune system.

Semenzas team found that 38 of the genes are influenced by the transcription factor HIF-1, which regulates how cells adapt to hypoxia; among the 38 was BIRC2 (baculoviral IAP repeat-containing 2), already known to prevent cell suicide, or apoptosis, in essence a form of programmed cell death that is a brake on the kind of unchecked cell growth characteristic of cancer.

BIRC2 also blocks cells from secreting proteins that attract immune cells, such as T-cells and natural killer cells.

First, by studying the BIRC2 genome in human breast cancer cells, Semenzas team found that hypoxia proteins HIF1 and HIF2 bind directly to a portion of the BIRC2 gene under low oxygen conditions, identifying a direct mechanism for boosting the BIRC2 genes protein production.

Then, the research team examined how tumors developed in mice when they were injected with human breast cancer or melanoma cells genetically engineered to contain little or no BIRC2 gene expression. In mice injected with cancer cells lacking BIRC2 expression, tumors took longer to form, about three to four weeks, compared with the typical two weeks it takes to form tumors in mice.

The tumors formed by BIRC2-free cancer cells also had up to five times the level of a protein called CXCL9, the substance that attracts immune system T-cells and natural killer cells to the tumor location. The longer the tumor took to form, the more T-cells and natural killer cells were found inside the tumor.

Semenza notes that finding a plentiful number of immune cells within a tumor is a key indicator of immunotherapy success.

Next, to determine whether the immune system was critical to the stalled tumor growth they saw, Semenzas team injected the BIRC2-free melanoma and breast cancer cells into mice bred to have no functioning immune system. They found that tumors grew at the same rate, in about two weeks, as typical tumors. This suggests that the decreased tumor growth rate associated with loss of BIRC2 is dependent on recruiting T-cells and natural killer cells into the tumor, says Semenza.

Finally, Semenza and his team analyzed mice implanted with human breast cancer or melanoma tumors that either produced BIRC2 or were engineered to lack BIRC2. They gave the mice with melanoma tumors two types of immunotherapy FDA-approved for human use, and treated mice with breast tumors with one of the immunotherapy drugs. In both tumor types, the immunotherapy drugs were effective only against the tumors that lacked BIRC2.

Experimental drugs called SMAC mimetics that inactivate BIRC2 and other anti-cell suicide proteins are currently in clinical trials for certain types of cancers, but Semenza says that the drugs have not been very effective when used on their own.

These drugs might be very useful to improve the response to immunotherapy drugs in people with tumors that have high BIRC2 levels, says Semenza.

Scientists who contributed to the research include Debangshu Samanta, Tina Yi-Ting Huang, Rima Shah, Yongkang Yang and Fan Pan of Johns Hopkins.

Marking Environmental Progress Earth Day’s 50th Anniversary Part VI – Mackinac Center for Public Policy

Throughout 2020, much of our attention has been focused on the uncertainties brought on by the novel coronavirus and the prolonged election season. With so much of our time and effort taken up by lockdowns, personal distancing and campaigns, it has been a struggle to keep track of many of the other issues that typically affect our lives.

Despite the almost overwhelming litany of distractions, the Mackinac Centers Environmental Policy Initiative has spent the past several months putting together a list of 50 reasons people can be optimistic about our future. We chose to list 50 separate technological and environmental innovations that have helped human life to flourish on our planet, and not because that was all we could find. In fact, there are so many more examples to list that we could have kept this up for a great deal longer. We chose to narrow the project to a list of 50 to recognize the fact that 2020 is the 50th anniversary of Earth Day.

So far, weve seen 45 different ways that humanity has improved the environment for ourselves and the planet. Those reasons include:

With this post, we will finish off the final five ways human ingenuity is improving our environment and helping people to live healthier, longer, more fulfilled lives:

This completes our 50th Anniversary of Earth Day list of reasons people have to be optimistic about their future. Human ingenuity has developed amazing technologies and found numerous new ways to solve the environmental challenges we face. Whether these innovations help us find cheaper and cleaner energy sources, expand our ability to treat disease, decrease poverty, increase our access to food, stop species extinctions, or protect us from the impacts of natural disasters, their common element is the creative potential of the human mind.

Humanity is often wrongly maligned by green groups, elected officials, and the media as a necessarily destructive influence on our Earth. But our 50 examples demonstrate this is simply not the case. We have only published 50 reasons in this series, but the human mind has not yet begun to approach the limit of what it can achieve.

Biological Risks in India: Perspectives and Analysis – Carnegie Endowment for International Peace

Summary

Infectious diseases such as COVID-19, the disease caused by the novel coronavirus; severe acute respiratory syndrome (SARS); Middle East respiratory syndrome (MERS); and the diseases caused by the Ebola, Nipah, and Zika viruses have exposed countries susceptibility to naturally occurring biological threats. Even though scientists from multiple countries concluded that the virus responsible for the coronavirus pandemic shifted naturally from an animal source to a human host,1 the international community should not ignore the possibility of pathogens escaping accidentally from research labs and threats of deliberate manipulation to create more dangerous bioweapons.

India is especially vulnerable to such infections because of its geographical position, large population, low healthcare spending, minimal expenditure on research that benefits public health, weak coordination between central and state health authorities, limited involvement of private actors, poor awareness of biosecurity, and the rickety state of public health infrastructure. Most recently, COVID-19 has revealed the deep fault lines in Indias public health infrastructure, including a shortage of healthcare workers, lack of trained epidemiologists, scarcity of medical equipment, poor access to healthcare facilities in rural areas, and inefficient disease reporting and surveillance in most states. The pandemic should therefore be a wake-up call for India to assess gaps in its public health infrastructure and divert its resources toward the healthcare sector to prepare itself for both natural and man-made biological emergencies.

Like any country, India faces three major biological threats: naturally occurring infections in humans or animals, or agricultural infestations; infections arising from accidental release of pathogens into the environment; and possible outbreaks caused by deliberate weaponization of dangerous pathogens that affect humans, animals, or crops. These threatseither alone or togetherwill force India to strengthen its capacity to detect and respond to them.

Shruti Sharma is a research analyst with the Technology and International Affairs Program at the Carnegie Endowment for International Peace. She works primarily on the safety, security, and ethical implications of emerging biotechnologies.

In all of this, there is a further challenge to wisely manage the trade offs between regulations to reduce the risks of accidents and attacks, on the one hand, and on the other, policies that enable government, scientific researchers, and industry to develop and market beneficial applications of biotechnology. Breakthroughs in biotechnology will be necessary to treat or vaccinate people against naturally occurring diseases as well as to detect and counter potential human-made threats and their consequences. This means researchers, businesses, regulators, media platforms, nongovernmental organizations, and voters must strive to educate themselves and their audiences or constituencies about possible threats and about the socially beneficial ways to prevent and manage them.

This paper addresses these varied challenges faced by India. It is based on interviews and informal conversations with leading government officials, scientists, academicians, and private-sector experts, as well as insights from workshops, roundtable discussions, and extensive literature review. Given Indias vulnerability to infectious disease outbreaks, the goal is to provide all stakeholders and the Indian public with an understanding of the biological risks facing India and the existing policies and involvement of various agencies working to enhance safety, security, and responses to threats. The paper further provides a brief assessment of how these policies are being implemented today and the scope of enhanced and better implementation in the future. The aim is to highlight the vital roles that bioscience, technology, and industry can play to advance the well being of Indian citizens while reducing risks of natural or human-induced afflictions.

To address safety and security risks, India follows two different approachesbiosafety and biosecurity. Biosafety seeks to protect humans from pathogens while biosecurity protects pathogens from humans.2 Though these two concepts and practices reflect diverse scenarios and mitigate different risks, they complement each other. Robust implementation of biosafety protocols, in addition to reducing the risk of accidental exposure, limits risks of intentional theft or misuse.8

Biosafety regulations in India are defined under the 1986 Environment Protection Act, with implementation broadly distributed between the Ministry of Science and Technology and the Ministry of Environment, Forest, and Climate Change (MOEFCC). These regulations have three aims:

Like biosafety, biosecurity regulations in India, although not clearly defined and categorized, empower different ministries or agencies that are responsible for sectors usually associated with human health, food safety, agriculture, livestock, and the environment. As no uniform definition of biosecurity exists globally, the concept differs across human, animal, and plant health sectors. Biosecurity for public health often refers to the protection of microbiological assets from theft, loss or diversion, which could lead to the inappropriate use of these agents to cause public health harm.4 However, because biosecurity for plant and animal health entails protecting biological resources from foreign or invasive species,5 regulations in India are broad enough to cover four major aims:

Even though India has enacted laws and regulations to protect the country from biological threats, the coordination and monitoring of their implementation remains irregular.

For the first category of biological threatsdiseases emerging from natural sourcesIndia has invested in a public health infrastructure and has various laws and guidelines that drive preparedness and response to naturally occurring disease outbreaks. However, Indias response to the avian influenza, Nipah virus disease, and COVID-19 has exposed the countrys rickety public health infrastructure, poor disease surveillance network, inadequate coordination between ministries to prevent zoonotic infections, absence of a national policy on biological disasters, and dismal investment in scientific research. Rather than using the time between outbreaks to develop national guidelines to tackle infectious diseases, India mostly relies on ad hoc notifications and guidelines, along with World Health Organization (WHO) advisories.

For the second category of threatsdiseases caused by accidentIndia has developed comprehensive biosafety guidelines to monitor the safety of biotechnological research. Although implementation of biosafety guidelines falls under the ambit of the Ministry of Science and Technology and MOEFCC, researchers often work in labs supported by the Indian Council of Medical Research (ICMR) and the Indian Council of Agricultural Research, which are research bodies set up under the Ministry of Health and Family Welfare (MOHFW) and the Ministry of Agriculture and Farmers Welfare. The multiplicity of organizations operating under different ministries makes it difficult to ensure implementation of biosafety guidelines across the country. Moreover, the system often experiences poor coordination between center and state regulatory units. In addition, some experts interviewed during the project note that while scientists or researchers perform all necessary safety tests before approaching the regulatory authorities, the approval agencies, perhaps influenced by activist groups, perform additional safety tests that delay the clearance of such products.6 Whether such additional tests are necessary or not is often disputed.

For the third category of biological threatsthreats emerging from intentional sourcesIndia has no specific biosecurity policy or legislation but has a multiplicity of regulations that address threats emerging from different sources. However, enti
ties set up under different ministries with inadequate collaboration among them leaves India vulnerable to a variety of foreign threats. While security agencies, such as the National Security Council Secretariat, are responsible for investigating a security threat, response to an event is often coordinated by civilian ministries.7 Because threats emerging from biological sources have a technical component, security agencies often include experts from other government departments, such as the Defence Research and Development Organisation, for their scientific inputs. Some experts, however, highlight that biosecurity discussions are mostly confined to closed policy circles and rarely involve experts from outside the government, leading to poor nationwide biosecurity awareness in India. Further, most regulations cover the export and import of pests and pathogens but do not adequately cover commercially ordered (mostly through e-commerce platforms) deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) sequences that may encode virulent genes. At present, biosecurity regulations often empower customs officials as the only authority that can check the baggage of incoming passengers. But most customs officials are inadequately trained to identify specific pests or pathogens. In addition, there seems to be no systematic assessment of vulnerabilities in the existing system nor development plans and methodologies to build a sustainable, functional, and well-equipped system to counter biothreats.

Beyond the need to prevent outbreaks caused by safety and security lapses, any system must also be able to respond to threats whether they occur through human action (and inaction) or through natural processes. Although security agencies require time to investigate if an outbreak is natural or man-made, the mitigation strategy to tackle the threat must be prepared in advance and implemented immediately after detection of an outbreak.

As the spread of infectious diseases is a long-term, continuous, and evolving threat, India may need an agency specifically responsible for preventing and managing biological threats. India could consider investing in an agency that can coordinate policy responses for any biological emergency. A full-time Office of Biological Threats Preparedness and Response (BTPR) under the National Disaster Management Authority (NDMA) is being suggested as an alternative. This paper sketched out this idea to stimulate further dialogue among interested stakeholders. This office could focus on naturally occurring diseases, threats emerging from laboratory accidents, and deliberate weaponization of diseases. Because India has numerous organizations that sometimes perform overlapping roles with limited or no coordination with each other, the office could become a nodal agency that brings together experts from different ministries, representatives from the private sector, and experts from the academic and scientific community.

Whether or not a new office is set up, it is important for India to review domestic measures needed to predict, prevent, and respond to both natural and man-made biological threats. These measures include:

Outbreaks of life-threatening infectious diseases such as the Ebola virus disease in West Africa, the Zika virus disease in South America, severe acute respiratory syndrome (SARS) in China, and the Nipah virus disease in India are not only limited to the region but frequently put people all over the world at risk. Most recently, COVID-19, the disease caused by the novel coronavirus, originated in China in late 2019 and rapidly evolved into a global pandemic, clearly demonstrating the harm infectious diseases can cause to the world economy and health security.

Natural processes of mutation and transmission caused these threats to human society. Human beings could create similar or even more dangerous threatsby accident or on purpose. Such accidents happened, for example, in 2003 when a Singaporean researcher acquired SARS from inadvertent cross-contamination of viral samples.8 In 2004, the accidental release of the SARS virus from a Chinese laboratory infected nine people, one of whom died.9 In 2014, a researcher working in a lab in India was accidentally infected with buffalopox virus,10 and in 2019 more than 3,000 brucellosis cases were detected in China due to contaminated exhaust from a brucellosis vaccinemaking company.11 Going further back in history, during World War II, Japan deliberately used pathogens to spread plague, anthrax, typhoid, cholera, and other diseases among Chinese military and civilians.12 The United States and the Soviet Union developed major biological weapons programs during the Cold War,13 which Russia, then part of the Soviet Union, continued illegally even after it signed the Biological Weapons Convention in 1972.14 Yet, if societies and governments overreact and impose ill-conceived regulations to control these risks, they would defeat themselves by depriving the world of the great benefits that bioscience and technology can provide. The study of genes and their functionsgenomicsenables researchers to understand the genetic causes of human, animal, and plant maladies. Synthetic biology and gene-editing tools such as the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and CRISPR associated protein 9 (Cas9) can be used to modify genes to fix maladies and to create new functionalitiesfor good or ill, as discussed below. Bioscience and technology together are needed to produce vaccines that prevent the spread of infectious diseases such as COVID-19 and medicines that treat people who could not be vaccinated. New biotechnologies also promise to advance prevention and treatment of other human afflictions and to boost agricultural productivity and sustainable development.

This paper is divided into five sections. The first section describes how different stakeholders perceive and think about the possible benefits of biotechnology and the factors that could prevent these benefits from being realized. Based on interviews and informal conversations with leading government officials, scientists, academicians, and private-sector experts, as well as insights gleaned from workshops, roundtable discussions, and extensive literature review, the paper highlights Indias vulnerability to three major categories of biological risks:

Based on these perspectives, the paper argues that societies need to create a healthy balance between innovation, commerce, and regulation to ensure safety and security. This means researchers, businesses, regulators, media platforms, nongovernmental organizations, and voters must strive to educate themselves and their audiences or constituencies about possible threats from biotechnology and about the socially beneficial ways to prevent and manage them so that this technology can be used to enhance social welfare.

Next, the paper focuses on the first category of risk, which is probably the largest biological danger if multiplying the probability of occurrence with the consequences of occurrence. And, because naturally occurring sources of infectious disease in human beings and animals will occur, even if human-made ones do not, this paper, through brief case studies, explores Indias plans and capacity to detect and mitigate biothreats once they have dispersed into the larger environment and human population. Assessing the gaps in Indias response to disease outbreaks, this section of the paper suggests that New Delhi must create, fund, and deploy capabilities to detect, mitigate, and eventually prevent naturally occurring outbreaks. Most, if not all, of the policies and capabilities needed to respond to natural outbreaks would be vital also in responding to biological attacks and accidents, which is an argument for prioritizing them.

The third and fourth sections elaborate on how India seeks to protect against infections arising from accidental or deliberate release of pathogens through biosafety and biosecurity regulations, respectively.

While biosafety is the protection of humans from pathogens, biosec
urity is the protection of pathogens from humans.15 Though these two concepts and practices reflect diverse scenarios and mitigate different risks, the paper argues that they share a common goal of keeping biological materials and the world safe and secure.

The final section of the paper identifies areas where stakeholders can work together and proposes a new nodal organization called the Office of Biological Threats Preparedness and Response (BTPR), operating under the National Disaster Management Authority (NDMA), to strengthen Indias capacity to tackle biological threats. Whether or not the office is set up, this section proposes other recommendations to strengthen Indias public health infrastructure, necessary to tackle both natural and manmade biological threats.

Emerging technologies can provide immense and widespread public health benefits by enabling the global scientific community to improve diagnostics and treatments of diseases that afflict human beings, animals, and plants. The benefits of some methods and new biotechnologies sometimes entail risks such as the accidental spilling of pathogens from the labs or the deliberate misuse of technology to create more dangerous pathogens. Other types of research may come with risks that are commensurate to the potential large-scale benefits they could provide. For example, to evaluate the effectiveness of current and future public health interventions, scientists in the United States have re-created the Spanish flu virus, the pathogen responsible for the worlds deadliest pandemic to date.16 To develop better vaccines and cancer therapeutics, Canadian researchers have synthetically reconstructed an infectious horsepox, a close relative of smallpox.17 Gain-of-function experiments, which increase transmissibility or virulence of pathogens, if undertaken with extreme care, can develop better vaccines by enhancing the pathogenicity of potential pandemic pathogens, such as coronaviruses, in laboratories in order to test new ways to kill or slow them.18

While such research promotes scientific understanding and provides tools to design medical countermeasures to reduce global disease burden, experts in India understandably worry that wide applications of dual-use technologies and decreasing barriers to access them raise safety and security concerns.

Given Indias geographical placement and history of infectious disease outbreaks, there are three major concerns that exist under this category:

India lies within the distribution zone of disease vectors, such as Aedes aegypti, a mosquito that carries and transmits viruses. India is therefore prone to mosquito-borne diseases such as dengue fever, malaria, Japanese encephalitis, and chikungunya virus disease. The vulnerability to vector-borne diseases is exacerbated by its tropical climate and annual monsoon season.19

Additionally, several scientific and academic experts in India stress that among a myriad of different diseases, viral infectionsespecially the ones that jump from animals to humans, called zoonotic diseaseshave the potential to cause devastation in India.20 Scientific experts further suggest that smaller genomes, higher replication speed, and greater transmission rates make it easier for certain pathogens, especially viral pathogens, to cause infections. Moreover, the high density of livestock and the difficult-to-regulate interface between human and animal populations make India more vulnerable to contagious viral zoonotic diseases. West Nile, avian influenza, swine flu, SARS, Middle East respiratory syndrome (MERS), Ebola virus disease, Nipah virus disease, and COVID-19 are examples of such zoonotic diseases. This is compounded by the unhygienic maintenance and breeding of livestock for human consumption.

Some industry and scientific experts in India emphasize that viral infections lead to secondary bacterial infections. Increasing rates of antibiotic resistance, a subset of antimicrobial resistance, is an emerging health trend in the country.21 Human pathogens frequently isolated from infections in patients and hospital sources have been growing more resistant to commonly used broad-spectrum antibiotics. Major contributors to this growing problem include poor patient adherence to antibiotic treatment, nontherapeutic use of antibiotics for growth promotion in farm animals, self-medication, and illegal over-the-counter access to antibiotics.

There are four major biosafety threats in India:

Several scientific, academic, and industry experts stress that personnel in some of the laboratories might have a poor understanding of the prescribed laboratory procedures and/or may be inadequately trained to follow them. This can result in ignorant mishandling of pathogens, cross-contamination of samples, inadequate oversight in a laboratory, or uncontrolled experiments.22

Several scientists in India note that by improperly handling a live attenuated strain of virus that is being used to develop a vaccine, for example, laboratory personnel could unintentionally make the pathogen more virulent. This could either lead to an unforeseen infection of the personnel or their local communities, or even a pandemic.

These risks are not unique to India. In 2001 in Australia, for example, scientists hoping to render a mouse infertile instead accidentally created a lethal mousepox virus.23 In the Soviet Union in 1979, anthrax spores were accidentally released from a Soviet military microbiology facility, causing livestock deaths and a few human fatalities.24 Almost seventy-five scientists from the U.S. Centers for Disease Control and Prevention (CDC) were exposed to anthrax because researchers failed to kill the bacteria and accidentally shipped live strains to other CDC labs that were not equipped to handle them.25 In another incident involving the CDC, a scientist cross-contaminated a benign strain of bird flu virus with a deadly bird flu strain, causing unintentional death of chickens, though it did not result in any human infection.26 These episodes demonstrate why layers of safety procedures and physical protection are necessary. Reviewing some of them, a few scientific and industry experts in India highlight that the absence of mechanisms to certify that all relevant laboratories are actually implementing safety standards for facilities, personnel training, and operations might lead to similar accidents in India in the future.

Moreover, multiple laboratories with different BSLs have been set up by the network established under the Indian Council of Medical Research (ICMR) across the country to deal with pathogens relevant to public health.27 Although a Department of Biotechnology (DBT) memorandum has introduced an application form to make certification and validation of BSL-3 and BSL-4 labs by the Review Committee on Genetic Manipulation mandatory,28 experts in India worry about the lack of national guidelines and absence of any accredited government or private agency for the certification and validation of BSL-2 labs, which are widely distributed all over the country.29 This is important because some of the BSL-2 labs sometimes work with biorisk group 3 pathogens, thereby raising safety concerns. Based on the objective of the laboratory, certification includes physical inspection of the facility to ensure that the building and infrastructure meet the design criteria and the basic requirements of protecting people and the environment from infectious agents. Validation, on the other hand, is necessary to review that the prescribed processes and procedures are followed within the laboratory. This includes having standard operating protocols and a training record of personnel in the laboratory. Certification and validation, according to experts, is necessary to ensure basic minimum standards are promoted and implemented to avoid unintentional exposure to high-risk pathogens.30 Scientists also emphasize that without proper disinfection, disposal of biomedical waste, including animals used for clinical and drug trials, is another serious biosafety hazard that might have ramifications
for public health.31 Large numbers of coronavirus patients all over the world have produced garbage contaminated with bodily fluids and other infectious material. Maharashtra, a state in central India, for example, observed maximum coronavirus cases in the country, generating an average of 1,500 kilograms of coronavirus-contaminated waste per day. According to civic bodies in the state, improper segregation of waste and inadequate equipment provided to garbage collectors increased the risk of transmission.32

In addition to the biosafety of laboratory operations, participants in this project have also expressed concern about safety outside the laboratory. Genetically engineered organisms could be introduced for purposes such as mosquito control, agriculture, environmental remediation, biofuels, and medications. These experiments or applications, according to some experts in India, raise the possibility of unintentional interaction with naturally occurring organisms, which if not adequately addressed and monitored, could lead to unintended consequences. Despite these concerns, some scientists emphasize the importance of genetically engineered organisms in reducing Indias vector-borne disease burden.33

The four major biosecurity threats relevant to the Indian context are:

Most experts in India acknowledge the value of biotechnology applications to improve the yield and nutritional quality of crops and to boost their resistance to diseases and drought.34 Naturally evolving pests and plant pathogens may be extremely invasive and costly to Indian agriculture. They can reduce crop production as well as negatively influence international trade. For example, the European Union in 2014 temporarily banned the import of Alphonso mangoes and a few vegetables from India after the consignment was found to be contaminated by pestsa potential threat to the unions salad crop industry and to Indian agricultural exports.35 Similarly, accidental introduction of blight-causing fungus from Asia led to the loss of American chestnut trees in the eastern United States.36

Some experts in India therefore worry that actors with nefarious intentions might deliberately release naturally occurring invasive pathogens or synthetically create pathogens or pests to target the agricultural supply chain.37 Individuals, businesses, terrorists, or hostile states could seek to bypass or break rules for a variety of reasons. Some might seek profit from more productive crops or livestock. Terrorists could seek to create panic and distrust within the society by introducing or claiming to introduce infectious disease into livestock. An enemy state could seek to impair military responses, paralyze government functioning, and decimate the economy.

Several experts in India also worry that nefarious actors could release naturally occurring known pathogens that have the capacity to cause widespread harm, such as anthrax or coronavirus. To influence election results in the U.S. state of Oregon, the Rajneesh group deliberately contaminated salad with the naturally occurring Salmonella bacteria, to reduce voter turnout on election day,38 and the Bacillus anthracis bacteria strain, isolated from an infected cow in Texas decades earlier, was used for the anthrax attack in 2001 that targeted prominent U.S. senators and media outlets, infecting seventeen Americans and killing five individuals.39 These real-world examples point to the fact that the development of biological weapons does not necessarily require genetic engineering.

More sophisticated malicious actorsboth inside and outside the labcould take advantage of genomic data that is now online and new and inexpensive synthetic biology tools to engineer deadly pathogens in a lab. Even for the information that is not available publicly, these actors can compromise the information system to gain unauthorized access to confidential genomic information. Thus, as one former government official emphasized, access to a pathogens culture is no longer a precondition to develop biological weapons.40 Custom-made genes can now be ordered online to produce drugs, vaccines, or other disease therapies. For example, do-it-yourself biologists, a group of amateurs who conduct biotechnology research outside a formal institutional setup, teamed up online to create coronavirus test kits and vaccines.41 Even though do-it-yourself biologists are independent researchers not linked to formal institutions, India does not have any policy to regulate them, thereby raising both safety and security concerns.42 Moreover, synthetic biology allows actors to develop pathogens from scratch in the lab. Large strands of deoxyribonucleic acid (DNA) can be created artificially, with the cost of DNA synthesis dropping from a dollar to less than ten cents per base pair in the last decade.43 Actors with nefarious intentions could order custom-made DNA strands online to create dangerous pathogens with enhanced virulence, transmissibility, and/or resistance to therapeutic interventions.

Individuals and groups have demonstrated intentions to get involved in such activities. A senior biodefense researcher in the United States was believed to have mailed anthraxobtained from a government labin letters that killed five people and infected seventeen others in 2001.44 A laboratory technician in the United States was charged in 1998 for stockpiling plague and anthrax and conspiring to use it as a weapon.45 Al-Qaeda reportedly made repeated attempts to acquire biological weapons,46 and operatives from the self-proclaimed Islamic State are known to have accessed information to weaponize pathogens.47 It is reasonable to assume that other such cases have been intercepted by various countries intelligence and security services without publicity.

Although advances in biosciences and technology can help contain and eradicate naturally occurring outbreaks, experts in India worry that since pathogens responsible for such infections are freely available in nature and the tools and technologies needed to manipulate them are easily accessible, developments in technology can lead to purposeful weaponization of such diseases. Not all pathogens have this versatile nature, and it requires tacit knowledge to weaponize them; for this reason, some government officials believe that it is more difficult than it might seem for an adversary to create and/or steal a bioagent with bioweapon potential and use it in devastating ways.

As pathogens do not respect national borders, some experts emphasize that they can be intentionally or unintentionally carried across borders. India shares porous borders with most of its neighboring states, so it is vulnerable and needs to secure its frontiers as much as possible and check travel and trade to prevent the proliferation of biological weapons.48 Recently, the director general of the police in Jammu and Kashmir claimed that Pakistan is pushing coronavirus-positive militants into Kashmir to spread the disease throughout the valley.49 Although the government in Pakistan has rebutted this claim, it indicates Indias vulnerability to cross-border infections.50

Discussions of biological risk naturally focus on the dangers of human action or inaction, purposeful or accidental. This is because human actions are controllable in ways that natural mutations of organisms are not. Human beings also fear losing things they already have more than they fear not gaining things in the future.51 From the perspective of societal well-being, then, some stakeholders in India see potential risks in restricting or burdening research, development, and applications of bioscience and technology without adequate evidence that the social benefits of such restrictions outweigh both their direct and opportunity costs. The two major areas that have faced strong public resistance in India are vaccines and genetically modified food/crops.

The World Health Organization (WHO) notes that fear of vaccine side effects has led to vaccine hesitancy.52 Although there is no organized antivaccination campaign, resistance to vaccines prevails in som
e parts of India, as concluded by a study that was commissioned after the reemergence of eradicated vaccine-preventable diseases such as diphtheria. The main reasons behind this growing trend are often the lack of trust in the government, fear of safety and efficacy of vaccines influenced by rumors, and poor communication regarding the benefits of vaccines.53 For example, resistance to the polio vaccine in some parts of North India was spurred by religious suspicions that the immunization drive was part of the governments agenda to control the high birth rate among the Muslim population. Similar resistance was observed with the human papillomavirus vaccine after rumors connected the vaccination to death among girls.54 Although dubious information is mostly spread by people with little or no scientific background, virus conspiracy theories are sometimes spurred by discredited researchers, as observed during the coronavirus pandemic.55 Such uncorroborated rumors regarding vaccines can sometimes jeopardize public health efforts to fight vaccine-preventable infectious diseases.

Similarly, people in India are more alarmed by the possibility that modifying plant genetics will accidentally reduce harvests or raise the costs of seeds for farmers than they are by the possibility that prohibiting such modifications will deprive them of faster growth in the future.

Experts have highlighted that no restrictions exist for plants or other organisms modified through traditional techniques. They added that traditional biotechnology techniques such as selective breeding, hybridization, and fermentation have been used to modify living plants for improved yield or enhanced nutritional value. In addition to producing the desired product, these traditional breeding techniques can lead to random mutations. With improvements in knowledge about the role of individual plant genes, modern biotechnology techniques can be used to edit the specific gene to produce a desired variety, thereby reducing the possibility of off-target effects.56

Despite widely documented economic, health, and environmental benefits of genetically modified crops, public backlash against these varieties, irrespective of their validity, has created a difficult political atmosphere in India where stringent measures have been developed to restrict transgenic research, field trials, and commercial product release.

Some Indian experts have witnessed mixed and varied reactions from the public and the government, depending on the product in question. They believe that it is not the technology but the way the product is perceived by the public that affects whether a product receives government backing. The primary example they used to highlight this was the contrasting treatment of genetically modified cotton and brinjal. The former is a cash crop widely accepted and in use, while the latter, a food crop, is still facing resistance to its introduction to the market.57

To address public concerns regarding biotechnology-derived products, the Indian government adopted a multilayered regulatory system to examine the safety of biotechnology products before their commercialization. However, the hierarchical setup is often plagued by coordination issues between various bodies at different levels. Bureaucratic delays in approving products sometimes lead to regulatory uncertainties. As a result, the private sector and the venture-capitalist community limit their investment in the biotechnology sector, constricting the scope of research in India.

First and foremost, it is important for India to periodically update the three categories of risks mentioned above. Once risk cataloging is complete, the next step is to identify and assess regulations that deal with each of these different categories of risk. For the first categorydiseases occurring because of natural mutationsit is important to understand the functioning of Indias public health infrastructure to identify gaps and limitations in the existing system. For risks emerging either from lab accidents or deliberate release, it is important to evaluate existing regulations against recent developments in biotechnology. Next, it is important to identify stakeholders that would be involved in dealing with each of these categories of risks. In addition to assessing regulations and identifying stakeholders, it is imperative for India to invest in scientific communication strategies to build a bridge between the scientific community and Indian society. This would help in fighting misinformation and would also help address public resistance to biotechnology-derived products, thereby spurring innovation.

As discussed above, biothreats can emerge from natural events, human accident, and/or malicious human action. This chapter focuses on Indias capacity to tackle the first category of riskthe ones emerging from natural sources.

In case of any disease outbreak, the central government issues specific notifications and guidelines to control and monitor the disease and has in several instances set up new ad hoc response committees. Like any naturally occurring biological disaster, accidental release or intentional attack also affects a countrys health infrastructure. Case studies of Indias responses to naturally occurring outbreaks can foster understanding of the health infrastructure.

To assess Indias capacity to handle human-induced biological threats, it is important to understand Indias responses to naturally occurring infections. The five case studies discussed in this section highlight Indias response toward agricultural infestations, such as the recently observed locust attacks; diseases that affect animals and have not yet infected humans, such as avian influenza; and zoonotic infections that have jumped from animals to humans, such as the Kyasanur Forest Disease (KFD), Nipah virus disease, and more recently COVID-19.

In 1957, India adopted an interdisciplinary approach to tackle an outbreak of KFD, a tick-borne viral hemorrhagic fever. The disease, commonly called the monkey fever, primarily infects primates and spreads to humans through ticks. The Rockefeller Foundation extended financial and technical support, including laboratory facilities to investigate the disease outbreak. Scientific expertise was provided by researchers at the National Institute of Virology, a lab set up by the Rockefeller Foundation (now under the ICMR). In addition, WHO supported an ornithologist who started the Bird Migration Project under the Bombay Natural History Society, which traces the origins and transmission of KFD.58

Epidemiological investigation of KFD was one of the early successful examples of the multidisciplinary approach needed to tackle zoonotic infections.59 However, no detailed studies have been carried out on any zoonotic pathogen in India, including the KFD virus, especially after the Rockefeller Foundation pulled its support in the 1970s.60 Even though most experts in India speculate that the next pandemic may also move from animals to humans, India has developed a more reactive approach to disease outbreaks rather than developing measures to prevent such infections. Independent ministries that are responsible for agriculture, animal husbandry, environment, and public health often work in silos and do not coordinate with each other. This leads to inadequate information sharing, which results in a weak surveillance mechanism needed for timely diagnosis of zoonotic infections.

It is therefore important to break the silos, develop robust coordination mechanisms for better information sharing, and develop a strong disease surveillance mechanism for early detection of diseases.

A high-density poultry population combined with the illegal movement of poultry and poultry products makes India vulnerable to avian influenza, a viral disease that affects both wild and domestic birds alike but very rarely infects humans. India has so far reported avian influenza, commonly called bird flu, almost every year, starting from 2005 until 2015. Fresh cases were again reported in 2020. Although state gover
nments have been successful in minimizing human infections so far, the response strategy mostly involves the mass culling of birds, as is done in other Asian nations. This policy response, however, entails huge financial cost for farmers and the poultry industry in general, without appropriate compensation. Most of these bird flu cases are restricted to rural areas; as a consequence, the lack of awareness along with the huge financial burden on farmers sometimes lead to underreporting of cases.61 It is therefore important to strengthen Indias disease surveillance mechanism that monitors and reports diseases in animals. Early detection of diseases in animals might help contain the spread of zoonotic infections, one of the major biological threats in India.

Nipah, a zoonotic virus that moved from bats to humans, killed seventeen people in the southwestern state of Kerala in 2018. Keralas State Surveillance Unit of the Integrated Disease Surveillance Programme (IDSP), an initiative led by the Ministry of Health and Family Welfare (MOHFW), reported the Nipah outbreak to the Central State Surveillance Unit of the IDSP. The Manipal Centre for Virus Research (now Manipal Institute of Virology [MIV]) at the Manipal Academy of Higher Education confirmed the Nipah outbreak, which was later reconfirmed by the National Institute of Virology in Pune.62

Following the confirmation of the outbreak, a multidisciplinary team from the National Centre for Disease Control (NCDC) was sent to Kerala to work locally with the state government to investigate and respond to the infection. The team was headed by the director of NCDC, with representatives from the National Institute of Virology; All India Institute of Medical Sciences; Ram Manohar Lohia Hospital; the Department of Animal Husbandry, Dairy, and Fisheries; and the Division of Emergency Medical Relief. This team was sent to support the local authorities to train medical personnel to detect and isolate active cases, trace their contacts, provide treatment, discard hospital waste, and safely dispose of the deceased. NCDC also activated the Strategic Health Operations Centre to monitor the outbreak and issue daily situation reports. In addition, WHO also provided support in terms of technical materials and guidance on the Nipah virus to both the MOHFW and the state health authorities. These coordinated and collaborative efforts of the central and the state government, along with WHOs technical support, led to an effective containment of the outbreak.63

Despite the successful containment of the outbreak, the central government determined that the lab that detected Nipah was underqualified, so it was dropped from a central list of virus research and diagnostic labs in 2019. The Ministry of Home Affairs (MHA) suspended the labs account under the 2010 Foreign Contribution Regulation Act (FCRA), which regulates foreign donations based on national security implications, for collaborating with the U.S. CDC for its research on the Nipah virus. Some government officials noted that the lab was being used to map the Nipah virus, which can be used to develop a vaccine, the intellectual property right of which will not be with India. Importantly, understanding how the human body reacted to the virus will also produce a more virulent form of virus for biological warfare.64 The laboratory, however, issued a clarification, emphasizing that the CDC was only involved in training to detect Nipah and was never involved in the actual Nipah investigation. Detection of the outbreak was exclusively funded and carried out in close collaboration with the ICMR. Samples for virus isolation were transferred to the National Institute of Virology. The statement issued by the laboratory further clarified that the research at MIV was not connected to any vaccine development and no intellectual property right was generated or transferred.65 Given that government bodies at the central level were aware of the research, including MIVs capacity to detect Nipah, the Health Ministrys sudden allegation and withdrawal of the labs FCRA license undermines the capacity of the lab and creates disincentives for other labs.

Not only does it undermine the potential of private labs, it also threatens prospects for global cooperation needed to tackle biothreats. Because biological threats, especially infectious diseases, are transnational in nature and cannot be tackled individually by national governments, international cooperation is both necessary and important in all facets of disease controlprevention, detection, warning, response, and the development of drugs and vaccines. While commercial considerations and debates around intellectual property are important, Indias biosecurity policy should foster global cooperation to advance knowledge and strengthen infrastructure to tackle biological threats.

Contrary to previous locust infestations that were localized to the northwestern states of Rajasthan and Gujarat, a latest locust attack that started in April 2020, much ahead of the normal July to October interval, damaged crops in the states of Gujarat, Madhya Pradesh, Maharashtra, Rajasthan, and Uttar Pradesh. Because winter crops were harvested and monsoon crops were yet to be sown, locusts in search of fodder moved deeper into India, affecting new states. Moreover, strong westerly winds from the Cyclone Amphan in the Bay of Bengal also influenced their widespread movement.66 Pandemic-induced economic slowdown made it difficult for the Indian government to tackle the invasion in a timely manner.

Locusts are transboundary pests that damage crops and threaten food security. Repeated locust infestations in India led to the 1939 establishment of Locust Warning Organisation, which in 1946 was integrated with the Directorate of Plant Protection Quarantine and Storage under the Ministry of Agriculture and Farmers Welfare.67 To combat the locust invasion, the organization worked closely with the MHA, Ministry of Civil Aviation, Ministry of External Affairs (MEA), Ministry of Defence, Ministry of Communications, relevant state departments, and other pertinent stakeholders, including farmers. At an international level, the Locust Warning Organisation coordinated with the Food and Agricultural Organization, a United Nations body that performs monitoring of possible locust outbreaks and issues timely warnings.68

Some states noted this locust invasion as mid-season adversity under the government-sponsored crop insurance program known as Pradhan Mantri Fasal Bima Yojana, which processes insurance claims for farmers losses.69 Although part of the claim is disbursed based on a joint survey conducted by the concerned insurance company and the state government, the remaining payment depends on the result of crop-cutting experiments that map damage from locusts at a village level. However, the methodology to conduct such experiments is skewed and depends on random selection of any four fields in the village. Because locusts do not affect all fields uniformly, random sampling sometimes does injustice to farmers, thereby causing financial strain.70 Moreover, pesticides used to limit the spread of locusts also adversely impact food crops, causing further financial troubles for the farmers.71

Given the impact of locusts on food security and agricultural supply chain, scientists all over the world are trying to genetically engineer locusts to control their spread.72 However, these experiments raise security concerns because the same techniques can be used to modify locusts or other insects in ways that would make it harder to control them.73 For example, scientific experts have raised concerns around the U.S. Insect Allies program that uses insects to spread viruses to create genetically engineered crops. While the program intends to develop healthier crops, some bioethicists and scientists believe that this technology poses serious safety and security risks.74 It is therefore important to strengthen Indias capacity to prevent, detect, and respond to natural infestations to better prepare for man-made invasions.

India obse
rved its first few COVID-19 cases almost a month after Chinese authorities officially reported the coronavirus outbreak to the WHO. The first three cases were reported in Kerala from January 30 to February 3, 2020, among students who came back from Wuhan, the Chinese city where the initial outbreak took place.75 Because health is a state subject in India, the Kerala government declared COVID-19 a state disaster as soon as it reported its third case. A multidisciplinary state response team was composed of experts in epidemiology, community medicine, infectious diseases, pediatrics, drug control, and food safety. This team was supported by other state-level teams to enhance the surveillance of the outbreak, train medical personnel, and strengthen the states public health infrastructure. In addition to the state response team, rapid response teams were also constituted at the district level to facilitate micro-level planning.76

A month later, in the first week of March, India witnessed a sudden spike in the number of coronavirus cases across the country. Recognizing the severity of the situation, the Prime Ministers Office (PMO) took charge. The response was guided by a team of more than thirty health experts and scientists who worked relentlessly to fight the contagion. This team was divided into two groupsone comprising health professionals and the other consisting of researchers from the ICMR and secretaries from the DBT, the Department of Science and Technology (DST), the Council of Scientific and Industrial Research (CSIR), and the Defence Research and Development Organisation.77Based on their recommendations, the government imposed severe travel restrictions to limit cross-border movement of people. In addition, all states and union territories were advised to invoke section 2 of the Epidemic Diseases Act of 1897 (EDA), which allowed them to take preventive measures to contain the spread of coronavirus in their respective states.

While measures taken by most states and union territories moved in the right direction, lack of uniformity across multiple states led to complications and impediments. To overcome this, the Indian government declared COVID-19 a notified disaster under the 2005 Disaster Management Act.78 As a result, Prime Minister Narendra Modi, who is also the chairperson of the NDMA, announced a nationwide lockdown, starting from late March through May 2020. Most states followed the central governments guidelines and directives to tackle the pandemic, but some states did not comply with the central government-issued advisories. This was caused by ambiguity in the constitutional structure, where health is classified as a state subject and disaster management, though not explicitly stated, falls under the concurrent list. While only state governments have the power to create laws for subjects falling under the state list, both central and state governments have powers over subjects mentioned in the concurrent list, with the centers decisions prevailing in case of differences. Because the central government declared COVID-19 a disaster, it gave both central and state governments the authority to draft rules and regulations to tackle the pandemic, with the central government playing an upper hand. Some states, however, argued that because health is a state subject, the states should have more flexibility in tackling the pandemic. This ambiguous nature of center-state relations complicated Indias fight to contain the pandemic.79

Recognizing the need to ramp up domestic capacity to strengthen Indias response to COVID-19, a task force was set up under DST with representatives from CSIR, DBT, DST, and ICMR; the Ministry of Electronics and Information Technology; Atal Innovation Mission; the Ministry of Micro, Small, and Medium Enterprises; Startup India; and the All India Council for Technical Education. This group tried to identify startups with market-ready solutions to develop affordable testing kits and to scale up manufacturing of equipment supplies such as masks, protective gear, sanitizers, ventilators, and respirators. The task force was also constituted to identify data-mapping solutions to develop an effective surveillance for coronavirus in India.80 Taking lessons from other countries, India also developed a contact-tracing app, called Aarogya Setu, to detect, trace, and isolate people who came in contact with COVID-19 patients.

Although the government took strict measures to implement social distancing, the country did not have adequate capacity to handle the pandemic.81 Personal protective equipment (PPE) for frontline medical workers was not easily accessible. Respirators, ventilators, and other equipment required to set up isolation wards were available in limited quantity. Diagnostic kits were also not available in sufficient quantity. In addition, the former Indian Health Secretary Preeti Sudan wrote a letter during the coronavirus pandemic stating that India needs to hire epidemiologists on a war footing because they are a critical element in the effective management of the pandemics like COVID-19.82 Hiring epidemiologists and microbiologists in the middle of the coronavirus pandemic indicates the shortage of trained personnel in India to fight the disease.83 Moreover, an academic expert in India highlighted that most scientific institutions in India prefer to recruit personnel who have received their degrees from abroad rather than hiring people who have been trained locally and have a better understanding of the Indian scientific and administrative environment. Such hires unfortunately lack an initial vision about the crisis from an Indian perspective and take time to adjust to the local system, which creates a longer lag phase and loss of valuable time, a crucial element during health emergencies.84

The above case studies clearly underscore Indias reactive approach toward infectious disease outbreaks. Rather than using the time between two outbreaks to develop national legislation to tackle infectious diseases, India mostly relies on ad hoc notifications and guidelines. Invoking the 2005 Disaster Management Act to tackle the COVID-19 crisis when this enactment is not geared toward handling epidemics in the first place highlights the poor state of Indias preparedness in combating infectious diseases.85

Complicating matters further, the Modi government reconstituted the NDMA and downsized it. The vice-chairman post was downgraded from Union Cabinet Minister to Cabinet Secretary, and members ranks were changed from Union Minister of State to Union Secretary of the Union government. According to the former vice chairman of the NDMA, this has weakened the organization, and there will be difficulty in coordination with the states in this regard. If a Vice-Chairman of Cabinet Minister status goes to a state, he will be meeting the Chief Minister more easily than somebody of Cabinet Secretary level. These are issues with protocol also.86

Capabilities, like the ones discussed in the previous section for tackling threats that naturally occur, would also be required to deal with human-induced outbreaks resulting from safety or security lapses. However, Indias responses to naturally occurring disease threats have exposed its poor disease surveillance network, inadequate coordination between ministries needed to prevent zoonotic infections, lack of a nationwide policy on biological disasters, rickety public health infrastructure, and minimal investment in research, all of which will be elaborated below.

For rapid surveillance and response to disease outbreaks, the NCDC, under the Indian MOHFW, set up an IDSP. The IDSP is a decentralized surveillance system that establishes surveillance committees at the central, state, and district level (see figure 1). The state surveillance committee is set up under the secretary of health; the district surveillance committee is under the chairmanship of the district collector or district magistrate. Information is relayed from the district unit to the state unit to the central surveillance unit on a weekly basis using an IDSP portal. This
weekly data gives insights on the disease trends and the seasonality of infections. In addition to these surveillance units, IDSP has also established multidisciplinary rapid response teams at the district level for early detection and containment of infectious disease outbreaks.87

Some public health experts in India have, however, raised serious concerns about the infrastructure and the human resource capabilities needed to accurately detect and report an outbreak. In addition to the IDSP, the Indian Health Ministry, under the National Health Mission, runs several other disease surveillance programs such as the National Vector-Borne Disease Control Programme, Revised National Tuberculosis Programme, and National Leprosy Eradication Programme.88 Moreover, there are additional surveillance programs such as the National Polio Surveillance Project (NPSP) that run beyond the ones included under the mission. These organizations sometimes collect data for the same disease, but often not with similar standards and practice. For example, both IDSP and NPSP record data for polio incidences in India. They use differing case definitions with little or no coordination (and often bureaucratic turf battles), which leads to different disease numbers being reported under different programs.89

Moreover, all these surveillance programs only mandate a few institutions, mostly government affiliated, to report disease outbreaks. This makes it difficult for organizations excluded from this network to report diseases. Limited involvement of private labs and practitioners in the disease reporting network leads to severe underreporting of disease outbreaks.90

In addition to disease surveillance programs that gather information on human infections, India runs parallel surveillance programs that collect data for livestock diseases. The National Animal Disease Reporting System, a computerized network set up under the Department of Animal Husbandry, Dairy, and Fisheries (within the Ministry of Fisheries, Animal Husbandry, and Dairying), collects and collates animal health information at the block, district, and state level.91 The National Animal Disease Referral Expert System is another web-based interactive livestock disease database that operates under the Indian Council of Agricultural Research, a body under the Ministry of Agriculture and Farmers Welfare.92

These multiple disease surveillance programs, set up under different ministries, work in silos and sometimes collect data for the same disease with different standards. This leads to the collection of redundant data, resulting in a convoluted, uncoordinated, and ineffective disease-mapping mechanism.

Indias response to biological disasters, both natural and man-made, is specified under the nonlegally binding guidelines for managing biological disasters, issued by the NDMA in 2008. The guidelines have clearly outlined the role of separate ministries in the wake of biological emergencies. MOHFW is responsible for handling naturally occurring biological disasters. The MHA is in charge of events arising through bioterrorism; the Ministry of Defence is responsible for events related to biological warfare; and the Ministry of Agriculture and Farmers Welfare has been put in charge of animal health and events related to agroterrorism. In addition, the guidelines mention the role of the community, medical care professionals, public health personnel, and veterinary professionals in preventing, responding, and mitigating the impact of any biological emergency.

Although the guidelines mentioned that the EDA should be repealed and a national-level policy for biological disaster should be framed, there is still no formal legislation for biological disasters. Because of the absence of a nationwide policy, many states have developed their own public health legislations to deal with disease outbreaks.93

The NCDC and the Directorate General of Health Services jointly prepared a 2017 public health bill, which was introduced in the parliament as the first step toward a formal legislation. The 2017 bill, which is now lapsed, was an attempt to replace the archaic 1897 EDA. Unlike the EDA, this proposed bill clearly defined an epidemic and identified thirty-five epidemic-prone diseases and thirty-six bioterrorism agents, high-priority pathogens that pose public health risk.94

This bill, however, has certain issues: it is more reactive than proactive, the measures included in the bill are insufficient and lack clarity, and it does not address the balance between public health and human rights.

Even though the NDMAs 2008 guidelines for biological disasters mention preventive options such as immunization of first responders or stockpiling of medical countermeasures, the new public health bill is not comprehensive enough and does not cover any prophylactic procedures. It only specifies scientific and containment measures that must be followed once the outbreak has happened. Key themes such as disease surveillance and identification of disease hotspots, development of vaccines, establishment of fully equipped hospitals, training for medical professionals, and coordination and collaboration among scientists and the biomedical industry appear to be missing in this proposed legislation. Besides this, the bill has not addressed the human resource component needed to contain disease outbreaks. For example, training of public health professionals, epidemiologists, and other frontline workers seem to be notably absent from the bill. Moreover, it fails to address budgetary challenges needed to create a robust public health infrastructure that is capable of tackling epidemics, bioterrorism, and biological disasters.

Although the bill empowers local governments to take measures to contain various diseases, it does not clearly explain the organizational structure that will operate in case of an emergency. Even though the bill mentions both natural and man-made biological threats, it has not clarified whether the setup would be operational under the guidelines issued by the NDMA or if a new authority will be established under the newly proposed bill.

In addition, some experts emphasize that the bill violates basic human rights and gives enormous powers to medical officers to inspect any location, isolate patients, limit their movement, conduct medical investigations, and treat them irrespective of their consent.95 To get a glimpse of what these powers might look like, consider a 2017 example where the Tamil Nadu state health department, under the Tamil Nadu Public Health Act of 1939, tried to make the measles-rubella vaccination mandatory for all children under the age of 15 without parental consent.96 Privacy concerns were also raised during the coronavirus pandemic when the Indian government deployed the Aarogya Setu contact-tracing app, meant to detect, isolate, and treat contacts of COVID-19-patients. Anyone using any public transport had to have the app installed on their phone, although it was not mandatory to download the app otherwise. Some data experts in India raised apprehensions regarding the privacy and consent framework of the app.97 The public health bill, if it is enacted, would need to be modified to include measures to prepare for a biological emergency and introduce provisions that balance public health and human rights.

Even though the MOHFW in 2016 conceded that Indias public expenditure on health as a percentage of gross domestic product (GDP) is far lower than countries classified as poorest in the world,98 the latest financial budget has increased the expenditure only marginally from 1.5 percent to 1.6 percent of the GDP.99 According to a few public health professionals, the Indian governments plan to increase its public health expenditure to 2.5 percent of GDP by 2025 looks disappointing when the global average will be about 6 percent.100

Given Indias minimal investment in public health, the coronavirus pandemic exposed the bleak reality that India only has 8.5 beds and eight physicians per million people, with even lower numbers reporte
d in rural areas.101 Although the WHO recommends a ratio of 1 doctor to 1,000 people, a recent study showed that India only has one government doctor per 10,819 people and one nurse per 483 patients, highlighting a deficit of 600,000 doctors and almost 2 million nurses.102

On top of this personnel deficit, healthcare workers tested positive for coronavirus, owing to the lack of protective health supplies such as masks, gloves, and gowns. The lack of healthcare workers and shortage of PPE kits both seem to have jeopardized Indias efforts to respond to the coronavirus disease. To divert all available public health resources to combat the pandemic, most hospitals in India closed their outpatient departments, thereby creating a huge problem for non-COVID-19 patients. As India has limited beds and facilities, several reports noted that patients with surgical procedures, routine checkups, and follow-up visits were deferred to avoid extra hospitalizations.103 Some states also halted immunization and reproductive health outreach to free up community healthcare workers for COVID-19-related surveillance and contact tracing. As a senior official in the Health Ministry reportedly noted, India, with its high disease burden, would fare best by avoiding a situation like the Democratic Republic of the Congo was in after the Ebola crisis, where more people died of tuberculosis, malaria, and measles than from Ebola.104

Indias research and development spending fluctuates between 0.7 to 0.9 percent of its GDP, much lower than other countries like Brazil (1.3 percent), Canada (1.6 percent), the United Kingdom (1.7 percent), China (2.1 percent), France (2.2 percent), the United States (2.8 percent), Germany (3 percent), Japan (3.2 percent), South Korea (4.5 percent), and Israel (4.6 percent).105 Among various scientific departments, the Department of Health Research, set up under the MOHFW, received only seven crore rupees for the development of tools and technologies needed to combat disease outbreaks such as the new coronavirus. Furthermore, the departments apex research organization, the ICMR, which is responsible for setting up diagnostic laboratories across India, has always faced budgetary constraints. In 2016, the then director general of ICMR reported that although ICMR had asked for 10,000 crores for a five-year plan from 2012 to 2017, only 50 percent of the amount was sanctioned.106 Similar reports highlighted that in 2020, when ICMR budgeted 2,300 crores for operations, it was allocated 1,795 crores.107 This mismatch between demanded and allocated funds, along with minimal investment in research to set up diagnostic labs, could be one of the many factors that contributed to Indias abysmally low testing numbers toward the beginning of the coronavirus pandemic. Because the research pipeline is not adequately developed, the country also struggled to ramp up domestic production of diagnostic kits. Several experts noted that this budget crunch might be detrimental to research and might impact innovation in public health.108

Repeated outbreaks of infectious diseases along with a huge burden of noncommunicable diseases should be a warning for policymakers in India to invest more in public health, build capacity to face a biological emergency, strengthen its disease surveillance mechanism, enhance interministerial collaboration to avoid bureaucratic bottlenecks, and spend time to develop a strategy to respond to disease outbreaks (see box 1).

The following are a set of recommendations for tackling diseases that emerge from natural sources:

To deal with the second category of risks (that is, risks emerging from human accidents), India has developed a series of biosafety guidelines and related rules and adherences to monitor and address the safety of research and its applications.

Biosafety seeks to keep laboratory workers and the surrounding environment physically safe from any unintentional exposure to dangerous or genetically engineered organisms. Personal protection such as laboratory coveralls and PPE to avoid accidental contact with blood, body fluids, and other potentially infectious material is necessary to ensure the safety of lab workers. Facility design and training to ensure safe handling of samples is important to reduce the possibilities of unintentional release of any organism into the environment.

Biosafety regulations and practices in India generally have three aims:

Indias 1989 Rules for Manufacture, Use/Import/Export, and Storage of Hazardous Microorganisms/Genetically Engineered Organisms or Cells (commonly called Rules 1989), notified under the 1986 Environment Protection Act, focuses on maintaining biosafety for all biotechnological experiments. These rules are supported by a series of guidelines issued by the DBT.109 These separate guidelines take into consideration the rapid pace of biotechnological advancements and the need to strengthen oversight for those involved in biotechnology research.

Under Rules 1989, DBT created the Review Committee on Genetic Manipulation (RCGM) to monitor the safety-related aspects of ongoing research projects or activities involving hazardous organisms. The RCGM includes representatives of DBT, the ICMR, the Indian Council of Agricultural Research, the Council of Scientific and Industrial Research, and other experts in their individual capacity. RCGM may appoint subgroups to assist RCGM on matters related to risk assessment and in reviewing existing and preparing new guidelines.110

Genetically Modified People Are Walking Among Us – The New …

It felt as if humanity had crossed an important line: In China, a scientist named He Jiankui announced on Monday that twins had been born in November with a gene that he had edited when they were embryos.

But in some ways this news is not new at all. A few genetically modified people already walk among us.

In the mid-1990s, fertility doctors in New Jersey got an idea for how to help women have children. They suspected that some women struggled to become pregnant because of defective material in their eggs.

To rejuvenate them, the doctors drew off some of the jellylike filling in eggs donated by healthy women and injected it into the eggs of their patients before performing in vitro fertilization.

The researchers did not ask the Food and Drug Administration for permission to try out the procedure. Only after their patients started having healthy children did they share the news that it seemed to work. Once the word got around, would-be parents streamed into clinics to try the procedure themselves.

But other people reacted with shock rather than excitement. Our cells generate fuel in miniature factories called mitochondria. And each mitochondrion carries its own small set of genes. The New Jersey fertility doctors might have created children with the DNA of three people, not two.

It turned out that this was indeed the case. The doctors discovered that some of the children carried mitochondrial DNA from the donors in addition to their parents. In their 2001 report on this discovery, they called it the first case of human germ-line genetic modification resulting in normal healthy children. The germ line is a lineage of cells that gives rise to a new person.

The F.D.A. was not pleased. It sent the clinics letters demanding that they apply to test the method as if it was a new experimental drug. Those bureaucratic hurdles were so daunting that the clinics stopped injecting eggs.

By then, perhaps a dozen children had been born with a mixture of DNA. Maybe there are more no one knows for sure.

The New Jersey doctors later tracked down some of these children and didnt find anything unusual about their health as teenagers. Meanwhile, some biologists had realized that a variation on their procedure might be able to do something else: prevent diseases that are otherwise incurable.

Like the DNA in our chromosomes, the DNA in our mitochondria can mutate. Mutations can cause symptoms ranging from blindness to early death, and women pass them down to their children. An estimated one in 5,000 people suffer from a mitochondrial disease, and for a vast majority, there are no effective treatments. Scientists wondered if they could erase these diseases by swapping mitochondria.

The procedure they envisioned began with taking a patients chromosomes out of one of her eggs. Next, they got an egg from a healthy donor and removed her chromosomes as well. Finally, they inserted the patients chromosomes into the donor egg and fertilized it with sperm.

Tests of this so-called mitochondrial replacement therapy, carried out on mice and monkeys, offered encouraging results. But when scientists approached the United States government about trying it out on human eggs, they got shut down.

It wasnt just the possible medical risks that worried people. Many saw it as an affront to human dignity.

It is a macabre form of eugenic human cloning, declared a Nebraska congressman, Jeff Fortenberry, at a hearing in 2014.

Two years later a provision was mysteriously slipped into a congressional budget bill that barred the F.D.A. from even considering mitochondrial replacement therapy. So researchers went underground.

In 2016, an American fertility doctor named John Zhang announced that he had gone to Mexico to quietly carry out the procedure on a woman from Jordan with a neurological disease called Leigh syndrome. She gave birth to a boy who appeared healthy. But she and her husband had no interest in letting scientists track the health of their child. We know nothing more of his fate.

This history echoed loudly this week, when Dr. He, an assistant professor at the Southern University of Science and Technology in Shenzhen, told the world that he had made gene-edited babies by altering the DNA of human embryos with a new technology called Crispr.

He cut out a small portion of DNA from a gene called CCR5. People who are missing this chunk of genetic material appear to be resistant to infections with H.I.V. Dr. He reasoned that genetically modified babies would resist the virus, too.

On Sunday, MIT Technology Review broke the news, followed by a lengthy story by The Associated Press. Dr. He posted a series of triumphant videos online, and on Wednesday, he went to a major gene-editing conference in Hong Kong to show slides with some details of his work.

Like the New Jersey fertility doctors before him, Dr. He was roundly condemned for his secretive recklessness. The organizers of the Hong Kong meeting issued a statement Thursday calling the birth of the twins irresponsible. They said Dr. He had designed the study poorly, and they labeled his ethical considerations a failure. Some scientists who watched Dr. He's talk wondered if he might have actually removed the wrong chunk of the CCR5 gene. The Chinese government called the procedure illegal and opened an investigation.

I got in touch with Glenn Cohen, a professor at Harvard Law School who studies reproductive technologies, to ask him to guess what happens next. His forecast sounded like a repeat of the mitochondrial replacement story.

My sense of what will happen is that across the world there will be strong regulatory action, Professor Cohen told me. He predicted a blanket ban of the technology. People are scared, and when they are scared they make decisions that are not so subtle.

On Wednesday, the commissioner of the F.D.A., Scott Gottlieb, appeared to give some credence to Professor Cohens prediction. In an interview with BioCentury, he criticized the scientific community for failing to stop Dr. He and warned of potential regulations and laws that could be far more restrictive than they might otherwise be if there were more confidence that the community was able to self-impose appropriate standards.

That would be a shame. There may be times when editing human embryos would make medical sense. Last year, the National Academy of Sciences and the National Academy of Medicine issued detailed guidelines about what sort of cases might qualify. While they didnt point to any particular disease, they argued that it should be considered only when no other treatment could allow parents to have a healthy child.

Fortunately, history offers us a different path. We need only look at what happened to mitochondrial replacement therapy in Britain.

When British scientists raised the idea of using the procedure on human eggs, the country conducted a serious, open conversation about the pros and cons. The health department conducted a long investigation. Parliament held a public debate. And in 2015 it passed a law approving the procedure.

The British government wasnt creating a medical Wild West, where doctors were free to use the procedure whenever they wanted. Clinics had to get a license from Britains Human Fertilization and Embryology Authority, which would monitor the procedures and track the children throughout their lives to check for unexpected side effects.

This February the authority announced that it was for the first time approving the use of mitochondrial replacement therapy on two women at a fertility clinic in Newcastle. On Thursday, a representative at the authority declined to say whether children had yet been born as a result.

Its only natural for the world to focus its attention on the two babies born in China. But these babies in Britain deserve our attention, too. We can choose which ones represent the future.

Genetic modification is ready to serve humanity The Miscellany News – Miscellany News

On Oct. 7, 2020, Dr. Emmanuelle Charpentier and Dr. Jennifer A. Doudna were awarded the Nobel Prize in Chemistry for their work in the field of gene editing. On top of breaking barriers as the first two women jointly awarded the chemistry prize, Charpentier and Doudnas recognition is a huge step forward for the controversial field of genetic engineering.

Humans have been practicing a form of genetic engineering ever since we started cultivating plants and livestock. Grafting two plants together dates back centuries in both the East and the West, and selective breeding was a staple technique used by even the earliest farmers. These techniques arent using advanced technology to target and change certain genes, but nevertheless the point of these exercises was to eliminate or diminish unwanted characteristics and promote the characteristics that the farmer found most useful. Wild cabbage was bred to create broccoli, brussel sprouts and domesticated cabbage. Cattle were bred to increase their edible volume. This was all uncontroversial, but it was all gene editing.

Today the techniques have changed, but the underlying mission has stayed the same: improve quality of life. Public opinion has shifted, however. Currently, more than half of adults in the U.S. believe that using genetically modified organisms (GMOs) as a food source is worse for your health than using non-modified foods. Of those, 88 percent believe that GMO foods will lead to health problems for the general populace. There is no such thing as non-modified food, but there is a stigma against food modified in a lab.

Part of this bias may be due to the way direct modification was introduced in the 1950s. In order to increase variation in plants so that selective breeding could be done more efficiently, scientists bombarded plants with radiation. This process, known as mutation breeding, was part of an effort to discover a peaceful use for the nuclear knowledge that was proliferating in the aftermath of World War II. Radiation was poorly understood by the general public in the mid-20th century. The possibilities of mutation due to radiation caused imagination to run rampant over reality: 1954s Them! stars giant insects caused by nuclear testing in the area.

The 1957 film Beginning of the End has grasshoppers eat mutated plants and then grow to enormous sizes. Even some of the most famous pop culture characters that exist today were formulated along these lines. In 1961 the Fantastic Four were given their powers by cosmic radiation. Spider-Man has had eight movies over the last 20 years, and he was famously bitten by a radioactive spider. These examples dont insinuate that people really believed that radiation could produce superheroes and skyscraper-sized insects, but they do reflect a general fear of the unknown that the gene modification of radiation could produce.

Radiation is no longer the bugaboo of the modern day, but fear of radiation has been displaced by fear of targeted gene editing, like the Crispr-Cas9 technique pioneered by Charpentier and Doudna. Some of this fear may be well founded: Theres no definite way to know that a gene edited plant or animal wont act similar to an invasive species. Presumably freed from some ailment or deficit that was limiting its growth, it is possible that a plant may grow at a pace that is higher than wanted by its creators. Nature is a delicate balance, and intervening must be done in a reasonable way that weighs the potential costs and benefits.

Mosquito reduction or elimination may not seem to be a worthwhile risk for something with unknown side effects, but that initial intuition would be wrong. Malaria, a disease transmitted mainly through mosquito bites, kills around 400,000 people per year. Zika and West Nile virus, while less deadly, are also transmitted into the human populace via mosquito. No other creature kills humans at the rate of mosquitoes. Despite the environmental damage that may be wreaked by the adjustment of the other flora and fauna to a lack of mosquitoes, gene editing to reduce mosquito population is a clear path to saving hundreds of thousands of lives every year.

With this sort of benefit in mind, the United States Environmental Protection Agency and Florida state government recently came to an agreement that will release over 750 million genetically modified mosquitoes into Florida. This is no small action and could potentially disrupt the entire food web of Florida, and possibly beyond.

The plan in Florida is to introduce a strain of Aedes Aegypti mosquitoes, a spreader of the Zika virus, that are genetically engineered so that their female offspring die off. Mosquitoes bite to extract human blood, and in this exchange mosquitoes can transfer any diseases they are carrying. Mosquitoes only bite so that they can extract iron and proteins in human blood and transfer it to the fertilized eggs that will be the next generation of that mosquitos bloodline. As such, the only mosquitoes that bite, and thus have the chance to transfer diseases, are adult females. The firm Oxitec produced a modified mosquito whose female offspring cant grow out of the larval stage. No adult females means no blood sucking, which means no disease transmission and no new mosquito larvae being produced.

A similar plan was executed in Brazil, where the Aedes Aegypti mosquito population was cut by 89 to 96 percent. With such a large reduction in mosquito population, the benefits move beyond that of just public health. Thousands of tracts of land would become more usable and see an increase in value if mosquitoes died out. Even day-to-day activities like gardening or talking walks could become much more pleasant in the absence of mosquitoes.

2020 has already shown the effects of disease and failures of public health. COVID-19 has killed over a million people; over the last 10 years, malaria has killed over four million. We have to live with COVID-19 for the foreseeable future, but gene editing has given us a tool to end malaria. Genetically modified mosquitoes should not end in Florida or with Aedes Aegypti: they should be of all species, placed all over the globe. For months the world has lived under a new biological terror. Its time we release a new biological salvation.

Synthetic Biology Speeds the Creation of Lab-Grown Livers – India Education Diary

Researchers at the University of Pittsburgh School of Medicine have combined synthetic biology with a machine-learning algorithm to create human liver organoids with blood- and bile-handling systems. When implanted into mice with failing livers, the lab-grown replacement livers extended life.

The study, published today in Cell Systems, shows that its possible to trigger and speed up the maturation of a lab-grown organ without sacrificing precision or control.

Mo Ebrahimkhani lab featurePregnancy is nine monthsit takes that long and even months after birth for new organs to maturebut if a person needs a liver, they may not be able to wait that long, said study author Mo Ebrahimkhani, M.D., associate professor of pathology and bioengineering, and member of the Pittsburgh Liver Research Center and the McGowan Institute for Regenerative Medicine. We showed its possible to get human liver tissue with four main cell types and vasculature in 17 days. We can mature tissue almost to the third trimester in only three months.

Other groups have attempted to coax organoid maturation in a dish using growth factors, but its expensive, inconsistent and prone to human error, Ebrahimkhani said. Often, there are unwanted tissue or cell typessuch as intestine or brain cells growing in the middle of what should be solid liver.

Using genetic engineering is cleaner but also more complex to orchestrate. So, Ebrahimkhani partnered with Patrick Cahan, Ph.D., at Johns Hopkins University to use a machine-learning system that can reverse engineer the genes necessary for human liver maturation.

Ebrahimkhani Vasculature releaseThen, Ebrahimkhani together with his collaborator at Pitt, Samira Kiani, M.D., applied genetic engineering techniques, including CRISPR, to turn a mass of immature liver tissueoriginally derived from human stem cellsinto what the team calls designer liver organoids.

The more mature the organoids got, the more capillaries and rudimentary bile duct cells snaked their way through the thin sheet of tissue, and the more closely the function of the tiny organ rivaled its full-size natural human model. Energy storage, fat accumulation, chemical transport, enzyme activity and protein production were all closer to adult human liver function, though still not a perfect match.

Ebrahimkhani imagines designer organoids having three main uses: drug discovery, disease modeling and organ transplant. Since the stem cells can come from the patients own body, lab-grown organs could be personalized, so there would be no threat of immune rejection.

When transplanted into mice with damaged livers, Ebrahimkhanis designer liver organoids successfully integrated into the animals bodies and continued to workproducing human proteins that showed up in the animals blood and prolonging the animals lives.

This is a proof-of-principle to show that its possible, Ebrahimkhani said. The technique could potentially go much further.

Our reference was a nature-designed human liver, but you can go after any design you like. For instance, you can make a genetic switch that protects the tissue from a virus, target the DNA of the virus and destroy it, Ebrahimkhani said. That sets this method apart.

Innovation in health and agriculture. We need to think bigger – World Economic Forum

2020 must be considered as a global turning point: the year when a lethal virus shook the global community. Within weeks, the pandemic severely affected our private and professional realities. Hundreds of thousands died. Millions lost their jobs. Entire industries slowed down dramatically. These fundamental changes to public life offer us unprecedented insights into our economy and its impact on our climate.

There is a broad consensus that the way we live and manage our economy is not sustainable. We face an urgent call to action. A large share of that responsibility lies with industrial companies like Bayer because, with our size and strength, we are capable of making a difference.

While this was true way before COVID-19, the pandemic has demonstrated how fundamentally we need to change. Despite the massive restrictions of this year from the postponed Olympics to the virtual UN General Assembly the International Energy Agency expects global CO2 emissions to drop by only 8% from 2019. In other words: large parts of the global economy were severely decelerated and our carbon emissions still remain more than 90% of what they were last year.

My takeaway is that behaviour changes like consuming and travelling less is certainly important, but not enough by far. In light of this pandemic, we can clearly see that we need to think bigger to succeed with the transformation to a sustainable economy. We need new technologies, breakthrough innovation and sustainable business models.

Inside the worlds labs, there is a technological revolution looming in the life sciences. Technologies such as synthetic biology, cell manufacturing, gene editing, artificial intelligence, microbe engineering, and others may change how patients are treated and food is produced.

Five years ago, Bayer decided to set up a separate unit, called Leaps by Bayer, solely focusing on breakthrough innovation with the potential to address some of humanitys biggest challenges. We began with the vision to invest in disruptive technologies that could shift key paradigms in our core business. In health, this means moving from treating, to curing and preventing diseases. In agriculture, its about moving from producing more, to better and more sustainable food.

We set out to address 10 huge challenges, such as curing genetic diseases or developing a sustainable protein supply. Each leap is outstandingly ambitious with the potential to impact millions of lives. In its operating model, Leaps stands for fostering access to cutting-edge technologies by collaborating with biotech start-ups. We have created or invested in more than 30 companies to date. In many cases, we provided not only capital, but access to Bayer resources, expertise and IP.

Each of the ventures in the Leaps portfolio is focused on new technologies that have been identified to best address the challenges. Gene editing, cell therapy, germplasm for vertical farming are only some of the technologies that Leaps has created companies around.

Sustainable organ replacement

One example for gene editings huge promise is in organ replacement. Worldwide, an estimated 1.5 to 2 million people are on organ transplant waiting lists. Only three in 1,000 people die in a way that their organs can be donated.

Kidney failure is one of the main drivers of organ transplant need, with nearly half a million Americans currently on dialysis. What if this diagnosis meant scheduling a prompt transplant operation, with low risks of organ rejection, and skipping dialysis entirely?

Technologies being developed by the Leaps company eGenesis like growing broadly compatible human organs using genetically modified pigs could end the global organ shortage, ensuring that patients everywhere have almost immediate access to life-saving transplants.

The environmental impact of agriculture

Modern agriculture is essential to feed the growing population of around 10 billion by 2050. On the flipside, agriculture is resource intensive, accounting for about a quarter of global greenhouse gas emissions and 70% of global freshwater withdrawals.

What if we could grow crops with significantly reduced farming inputs at reasonable costs? If the Leaps company JoynBio is successful in engineering the soil microbiome so that plants like corn could fixate nitrogen from the air, we could dramatically reduce the use of nitrogen fertilizer and the 3% of global greenhouse gases it generates today.

Around a century ago, the Haber-Bosch process revolutionized farming by allowing people to mass-produce nitrogen fertilizer. In our time, Leaps is working on the next revolution.

Two billion people in the world currently suffer from malnutrition and according to some estimates, we need 60% more food to feed the global population by 2050. Yet the agricultural sector is ill-equipped to meet this demand: 700 million of its workers currently live in poverty, and it is already responsible for 70% of the worlds water consumption and 30% of global greenhouse gas emissions.

New technologies could help our food systems become more sustainable and efficient, but unfortunately the agricultural sector has fallen behind other sectors in terms of technology adoption.

Launched in 2018, the Forums Innovation with a Purpose Platform is a large-scale partnership that facilitates the adoption of new technologies and other innovations to transform the way we produce, distribute and consume our food.

With research, increasing investments in new agriculture technologies and the integration of local and regional initiatives aimed at enhancing food security, the platform is working with over 50 partner institutions and 1,000 leaders around the world to leverage emerging technologies to make our food systems more sustainable, inclusive and efficient.

Learn more about Innovation with a Purpose's impact and contact us to see how you can get involved.

The societal value of innovation

Leaps by Bayer is our way of thinking big. I believe what we have learned can help restart a discussion about the value of new technologies in reaching the UN Sustainable Development Goals (SDGs) and transforming to a decarbonized economy. In my view, three points can help us harness these technological promises:

1. An honest discussion about risk-taking: "Who dares, wins" is an old saying, but its also the mindset we need. Im well aware that, especially in Europe, we are dealing with scepticism towards technological solutions. As societal acceptance is key, we should all engage in discussions about the value of innovation. This must include an honest exchange about cultural differences, the right regulatory framework and ways to ensure the responsible use of new technologies.

2. Companies and investors need to align their business models: In recent years, the binding force of the planetary boundaries has become scientifically obvious and the markets are reacting accordingly. At Bayer, we have aligned our business strategy with the SDGs. As a company and Leaps is a wonderful expression of that we thrive for what we believe is the ultimate goal of how to run a business: sustainable solutions and financial returns at the same time.

3. Nobody can do it alone: Our Leaps approach proves this rather general point. Its also a lesson that will remain from 2020. Dealing with the global health crisis and the scientific race to stop COVID-19 has encouraged unprecedented collaboration. Lets use this momentum for the greater good.

Could a mutant fish that was genetically engineered backwards tell us where we came from? – SYFY WIRE

Humans and fish (unless you mean a lungfish) dont really have much in common, except that they are both vertebrates, and all vertebrates have a common ancestor. But how do you go hundreds of millions of years back in time without a fossil of that ancestor?

Technology from the future has now given us a glimpse into the deep past. Biologists from the University of Colorado Boulder have now used CRISPR to genetically reverse-engineer the embryo of a sea lamprey (those freaky fish that stick to their prey and suck its guts out), making it devolve. The wormlike creature they created proved that removing the set of genes that makes vertebrates what they are rewinds evolution. It can also give us a better understanding of the ancestor we have in common with fish and everything else that has a skeleton.

"There is a single gene vaguely similar, and probably distantly related, to the Endothelin receptors in the genome of the invertebrate chordate amphioxus,"biologist Daniel Medeiros, who co-authoreda study recently published in Nature, told SYFY WIRE."What it does is unknown (we have tried to figure out what it does, but have failed so far). So the endothelin receptor likely evolved from some ancient cell surface receptor,perhaps by gaining some new protein coding sequence, or by exon shuffling (being accidentally combined with some other protein-coding sequence from another part of the genome)."

Its kind of like that spell of Ursulas in The Little Mermaid that turned poor unfortunate merpeople into primitive worm-things, just not so grim.

500 million years ago, vertebrates somehow evolved the group of genes that made them vertebrates. These genes make up the Endothelin (Edn) signaling pathway, which switches on specialized cells that develop into parts of the skeleton, the peripheral nervous system and pigment cells to multiply as the embryo develops. These cells are neural crest cells (NCCs). What Square and his team wanted to test was whether taking away the Endothelin signaling pathway would turn a vertebrate into an invertebrate that could be eerily similar to something that existed before skeletons were a thing.

Sea lampreys were used in the experiment because they evolutionarily diverged from other fish around the same time that vertebrates evolved the Endothelin signaling pathway. These jawless fish are living fossils, with ancient vertebrate features that at least give some idea of an early phase of vertebrate evolution.

"The evolution of what we think are two differentendothelin signaling pathways allowed neural crest cells to divide themselvesup into different groupscapable of doing different things," Medeiros said."We think, based on the lamprey mutant phenotypes, that this facilitated the evolution of different types of vertebrates with different head skeleton features."

Endothelin signals are zapped to different cells in order to tell them what functions to carry outthis is intercellular signaling. Ligands, or molecules that bind to other (often larger) molecules for a specific biological function, are released by signaling cells in this process. The ligands produce a chemical signal when they bind with a protein they target, which is the receptor of that signal. Ligands typically bind only to one particular receptor. Multiple ligands and receptors dedicated to varying functions are involved in Endothelin signaling.

"The endothelin ligands really appeared out of nowhere;there is nothing remotely like them in any invertebrate," Medeiros said. "They must have beentranscribed randomly from some non protein-coding DNA on accident at some point.This has been shown to happen in other animals, like fruit flies.Since they are not very large genes, I think that is a good possibility."

In an earlier study, Medierosand his team had analyzed the Endothelin signals in a frog and compared them to those in the lamprey, which they found has specific ligand and receptor pairs that are almost like similar pairs found in jawed vertebrates. This analysis formed the basis of what would be their work with CRISPR.

Genome duplication was previously thought to be behind the evolution of new traits, since copies of genes that already exist can assume new and possibly, such as in the emergence of vertebrates, unprecedented functions.

"You sequence the gene you targeted to make sure that you efficiently broke the gene, and can then analyze the defects caused by missing the gene," said Medeiros. "The CRISPR method uses the 'programmable'Cas9 enzyme, which cuts DNA. We can injected a solution with the Cas9 enzyme and a piece of RNA into the cell with a tinyglass syringe. In the cell, the Cas9 grabs the RNA guide, then moves into the nucleus and cuts the DNA where we want it, then you let the mutated embryo develop."

Mutant sea lamprey larvae showed just about none of the traits that distinguish vertebrates. What makes this experiment such a breakthrough is that it has been notoriously difficult to find the exact roles for genes that exist only in vertebrates. The team also realized that while gene duplication is definitely involved in evolution, it was not the holy grail that could give rise to an entirely new group of genes, such as NCCs, on its own. Formation of new genes has to be going on at the same time as duplications in order for that to happen.

Could you devolve a human like this? Probably not, but its awesome sci-fi-horror movie fodder. What might eventually be done, if you ask Medeiros, is the cancelling out of detrimental genes that could lead to defects.

"As long was we survive as a technological species, we will eventually understand genomes, how they have changed during evolutionto make new organisms, and also how it they are disrupted in genetically based diseases and cancer," he said."At that point we can rewrite the instructions in an intelligent way to create essentially whateverbiological outcome we want."

Human waste can offer advance warning of COVID-19 outbreaks – theday.com

Analyzing human waste could prove to be a valuable early detection tool to identify increases in COVID-19 cases or see where new hot spots might emerge.

An analysis of solid waste from a wastewater treatment plant in New Haven by researchers at Yale University and the Connecticut Agricultural Experiment Station from March 19 until May 1 showed that the amount of viral genetic material found in the waste corresponded with the COVID-19 infection rate in New Haven County.

In addition to providing trend data, the study also showed that the amount of virus found in the waste very closely matched hospital admissions data in New Haven County, said Jordan Peccia, Yale professor of environmental engineering and the project's lead researcher.

As Connecticut reopens its economy and lifts lockdown measures put in place to curb the spread of the virus, researchers said regular testing of solid waste could provide early warnings of new waves of infection and signal the need for more individual testing.

We were detecting increases in viral genetic material about seven days prior to the increase in the number of confirmed cases (in New Haven County), and three days earlier for hospitalizations, said Douglas Brackney, an associate scientist with the agricultural experiment station who is involved in the project. This can be a tool to predict overall community-wide activity and could be used to inform public health policy as well as preparedness in hospital settings and clinics and testing facilities.

The study took place early during the coronavirus pandemic in Connecticut at a time when testing was not widely available, so with more testing that gap gets smaller, Brackney said.

While COVID-19 testing is expensive and involves a lot of resources,analyzing waste can offer"a snapshot of community- wide activity almost in real time for a large part of states population at a much reduced cost, Brackney said.

But waste analysis is not meant to be a replacement for testing, which Peccia called the gold standard given thatit provides individual-level data about who is sick. Without that data, health officials cannot do contact tracing to identify who is sick orwho they came in close contact with them.

But data from analyzing waste can provide another piece of information for policymakers and officials to confirm infection rates in their communities.

Testing at the New Haven plant is ongoing, and researchers are providing data to the city of New Haven twice a week. With scaled-up resources, they could provide the data if not every day, then every two days, Peccia said.

Peccia is working to expand the testing to other parts of the state, particularly smaller cities such as New London and more rural areas, where often testing programs are not as robust as they are in more densely populated areas.

He is currently working on securing funding and said he hopes to expand the waste testing to about five or six other cities in the state by Aug. 1.

Joint Study by Sunway University and Harvard Medical School Shows Gene Therapy Can Advance Cancer Treatment – QS WOW News

Sunway Universitys Professor Jeff Tan Kuan Onn of the Department of Biological Sciences and Professor Poh Chit Laa from the Centre for Virus and Vaccine Research, along with their research collaborators from Harvard Medical Schools Center for Stem Cell Therapeutics and Imaging (USA) as well as University of Tennessee Health Science Centre (USA) have completed a study that has demonstrated the efficacy of molecular gene therapy as a new strategy for cancer treatment.

The research could potentially contribute to shorter treatment time for cancers, reduce treatment costs and minimize the adverse effects of current chemo-drugs in cancer patients such as susceptibilities toward microbial infections, hair loss, and other side effects of chemo-drugs that drastically affect the quality of life of cancer patients undergoing therapy.

Principal Investigator Professor Jeff Tan explained, Currently, chemo-drugs are relatively ineffective against cancer cells that have developed drug-resistance resulting in the need for high doses of chemo-drugs or a combination of chemo-drugs to be administered to patients with cancer cells. Chemo-drug resistant cancer cells also can spread quickly and that drastically reduce the survival rate of cancer patients.

Our research utilizes molecular gene therapy which is the introduction of genetic materials into cancer cells to promote the sensitivity of cancer cells to chemo-drugs. By genetically engineering the cancer cells, we find that we can induce the cancer cells to produce activated pro-death and tumor suppressor proteins that cause cell death and growth arrests in cancer cells. The weakened cancer cells can then be killed relatively easily by the administration of chemo-drugs in smaller doses. Ultimately, the research could contribute to increasing the survival rates of cancer patients undergoing cancer treatments he added.

Co-Investigator Professor Poh Chit Laa said that the effectiveness of the strategy has been demonstrated in mice implanted with human breast cancer cells. In the mice that were treated with the gene therapy, the tumors obtained from the treated mice showed significant tumor cell death and the tumors were 20 times smaller and 32 times lighter in volume and weight, respectively, when compared to the tumors obtained from the untreated mice. The results indicated that gene therapy was able to shrink the tumors significantly, even without treatment with chemo-drugs. Small doses of market-available anti-cancer drugs could then be used to kill the cancer cells effectively. We hope to see our research contribute to better survival rates of cancer patients, and minimize the side-effects associated with anti-cancer drugs, said Professor Poh.

We are currently working on investigations to optimize the delivery of the gene therapy and anti-cancer drugs to human tumors with hopes that this will result in tangible clinical outcomes, said Professor Jeff Tan.

The research project was recently published in the peer-review Journal of Cancer Research and Clinical Oncology. Collaborators for the research include Lee Yong Hoi, Pang Siew Wai and Samson Eugin Simon from the Department of Biological Sciences, Sunway University; Esther Revai Lechtich and Khalid Shah, of the Center for Stem Cell Therapeutics and Imaging, Brigham and Womens Hospital, Harvard Medical School (USA); Suriyan Ponnusamy and Ramesh Narayanan from the Department of Medicine, Centre of Cancer Drug Discovery, College of Medicine, University of Tennessee Health Science Centre (USA).

The research is a result of a collaboration agreement between Harvard Medical School and Sunway University aimed at developing new cancer therapies targeting drug-resistant cancer cells. In 2016, Professor Jeff Tan visited Harvard University on the Jeffrey Cheah Travel Grant which enabled him to better understand how cancer research projects are conducted as well as examining experimental models used to study cancer biology at Harvard University, Massachusetts General Hospital (MGH), a hospital affiliated with Harvard Medical School, and the Dana-Farber Cancer Institute.

In college, Elon Musk thought these 5 things would change the world – CNBC

The internet

Musk believed the internet, nascent in the '90s, would "fundamentally change humanity," he said on the podcast.

"I would not regard this as a profound insight but rather an obvious one," Musk said.

He compared the internet to the human nervous system: "If you didn't have a nervous system, you wouldn't know what's going on. Your fingers wouldn't know what's going on. Your toes wouldn't know what's going on. You'd have to do it by diffusion," he said.

"The way information used to work was by diffusion. One human would have to call another human or write them in a letter. [That was] extremely slow diffusion. And if you wanted access to books, and you did not have a library, you don't have it. That's it."

He knew the internet could change all that.

And while Musk only had minimal access to the internet at the time (only to use it for his physics studies, he said), he knew the internet would be a "fundamental and profound change."

"Now, you have access to all books instantly, and you can be in a remote mountaintop location and have access to all of humanity's information if you got a link to the internet," he said on the podcast. "Now suddenly, human organisms anywhere would have access to all the information instantly."

Musk believed "making life multi-planetary and making consciousness multi-planetary" would change the world, he said on the podcast.

As a child, Musk was influenced by a variety of science fiction booksand he believed he'd one day "[build] spaceships to extend the human species's reach," according tothe book"Elon Musk." (Musk previously said that theseven-book "Foundation" science fiction series by scientist and author Isaac Asimov, for example, was "fundamental to the creation of his aerospace company, SpaceX.")

On May 30, SpaceXsuccessfully launched two NASA astronautsinto orbit for the first time. It was a milestone forhuman spaceflightand got Musk one step closer to achievinghis Mars ambitions.

Just as a character in the 1997 movie Gattaca undergoes genetic engineering to pursue his dream of space travel, according to Musk, when he was younger he believed being able to change human genetics could change the world.

And it's happening today, with technology like Crispr, Musk said on the podcast.

"It will become normal, I think, to change the human genome for getting rid of diseases or propensity to various diseases," he said. "That's going to be like the first thing you'd want headed out. If you've got a situation where you're definitely going to die of some cancer at age 55, you'd prefer to have that edited out."

"There's the Gattaca sort-of extreme thing where it's not really edited out but it's edited in for various enhancements and that kind of thing," he said, "which probably will come too."

"I'm not arguing for or against it," Musk said. "I'm just saying it's more likely to come than not down the road."

As a teenager, Musk felt a "personal obligation" for the fate of mankind and felt inspired to create "cleaner energy technology" one day, according to the book"Elon Musk."

So he believed that sustainable energy would change the future.

"Sustainability, actually, was something that I thought was important before the environmental implications became as obvious as they are," he said on the podcast. "If you mine and burn hydrocarbons[compounds that form the basis of natural gas, oil and coal], then you're going to run out of them. It's not like mining metals.... We will never run out of metals, but we will run out of hydrocarbons."

He said the future may bring a carbon taxthat would raisethe cost of burning fossil fuels to mitigate climate change, which is a "no brainer."

In 2004, Musk invested in and became a co-founder ofelectric car companyTesla.Hebecame CEO in 2008. On Wednesday, Tesla became the world's most valuable automakerwhen the electric vehicle company's market capitalization surpassed Toyota's for the first time.

"AI is a really major one" too, Musk said on the podcast.

In 2019,at the World Artificial Intelligence Conference in Shanghai, Musk (who co-founded non-profit AI research lab OpenAIbut laterleft the company's board) said computers will "surpass us in every way," including scary things, likejob disruptionfrom robots or even apotentialAIracethatleadstoa third World War.

AI is "capable of vastly more than almost anyone knows and the rate of improvement is exponential," he saidhe said at the 2018 South by Southwest tech conference.

Musk also founded machine intelligence venture Neuralink, because he believes humans must merge with AI to avoid becoming irrelevant.

"We do want a close coupling between collective human intelligence and digital intelligence,"he said at the SXSW conference, "and Neuralink is trying to help in that regard by trying creating a high bandwidth interface between AI and the human brain."

Scientists have created monkeys with improved brain – The Times Hub

Scientists working at the Central Institute in Kawasaki and Japans Keio University have created monkeys with advanced brains. The study also involved genetics of the max Planck Society and German experts from the Institute of molecular cell biology.

The main feature of the human brain is the neocortex increased. We are talking about areas of the main organ of the CNS that are longer than those of other mammals, including monkeys. Scientists through genetic engineering techniques created the monkeys, which the brain became closer to the human. Because of ethnic barriers the scientists did not allow the monkeys to be born, because 50 days prior to the proposed birth interrupted the experiment.

The experts felt that a mandatory from an ethical point of view, you need to first determine the degree of influence of the new gene on the overall process of fetal development. The increase in brain size was achieved due to the fact that in the genome was added ARHGAP11B. This element is responsible for the enhanced process, the generation of stem cells. The gene is unique, because it has only human.

As scientists assume, ARHGAP11B appeared about five million years ago in the results of mutations. Then came the Neanderthals.
