UNIGE Scientists have discovered how the absence of a genetic switch can lead to malformations during embryonic development.

Embryonic development follows delicate stages: for everything to go well, many genes must coordinate their activity according to a very meticulous scheme and tempo. This precision mechanism sometimes fails, leading to more or less disabling malformations. By studying the Pitx1 gene, one of the genes involved in the construction of the lower limbs, a team from the University of Geneva (UNIGE), in Switzerland, has discovered how a small disturbance in the activation process of this gene is at the origin of clubfoot, a common foot malformation. Indeed, even a fully functional gene cannot act properly without one of its genetic switches. These short DNA sequences provide the signal for the transcription of DNA into RNA, and are essential for this mechanism. And when just one of these switches is missing, the proportion of cells where the gene is active decreases, preventing the lower limbs from being built properly. These results, which can be read in the journal Nature Communications, highlight the hitherto largely underestimated role of genetic switches in developmental disorders.

During embryonic development, hundreds of genes must be precisely activated or repressed for organs to build properly. This control of activity is directed by short DNA sequences that, by binding certain proteins in the cell nucleus, act as true ON/OFF switches. When the switch is turned on, it initiates the transcription of a gene into RNA, which in turn is translated into a protein that can then perform a specific task, explains Guillaume Andrey, professor in the Department of Genetic and Developmental Medicine at the UNIGE Faculty of Medicine, who led this research. Without this, genes would be continuously switched on or off, and therefore unable to act selectively, in the right place and at the right time.

In general, each gene has several switches to ensure that the mechanism is robust. However, could the loss of one of these switches have consequences? This is what we wanted to test here by taking as a model the Pitx1 gene, whose role in the construction of the lower limbs is well known, says Raquel Rouco, a post-doctoral researcher in Guillaume Andreys laboratory and co-first author of this study.

To do this, the scientists modified mouse stem cells using the genetic engineering tool CRISPR-CAS 9, which makes it possible to add or remove specific elements of the genome. Here, we removed one of Pitx1s switches, called Pen, and added a fluorescence marker that allows us to visualize the gene activation, explains Olimpia Bompadre, a doctoral student in the research team and co-first author. These modified cells are then aggregated with mouse embryonic cells for us to study their early stages of development.

Usually, about 90% of cells in future legs activate the Pitx1 gene, while 10% of cells do not. However, when we removed the Pen switch, we found that the proportion of cells that did not activate Pitx1 rose from 10 to 20%, which was enough to modify the construction of the musculoskeletal system and to induce a clubfoot, explains Guillaume Andrey. Indeed, the proportion of inactive cells increased particularly in the immature cells of the lower limbs and in the irregular connective tissue, a tissue that is essential for building the musculoskeletal system.

Beyond the Pitx1 gene and clubfoot, the UNIGE scientists have discovered a general principle whose mechanism could be found in a large number of genes. Flawed genetic switches could thus be at the origin of numerous malformations or developmental diseases. Moreover, a gene does not control the development of a single organ in the body, but is usually involved in the construction of a wide range of organs. A non-lethal malformation, such as clubfoot for example, could be an indicator of disorders elsewhere in the body that, while not immediately visible, could be much more dangerous. If we can accurately interpret the action of each mutation, we could not only read the information in the genome to find the root cause of a malformation, but also predict effects in other organs, which would silently develop, in order to intervene as early as possible, the authors conclude.

Missing Genetic Switch at the Origin of Malformations During Embryonic Development - SciTechDaily

There is a possibility that the COVID-19 virus was "most likely" leaked from a lab in China,British MPs were informed on Thursday.

Harvard scientist Dr Alina Chan, while testifyingbefore the House of Commons Science and Technology Committee, said that it was reasonable to hypothesise and investigate whether the Covid virus was modified in the lab.

The first cases were linked to a seafood market in Wuhan, which is located acrossthe Yangtze riverwhere a virology lab is located.

When asked by the panel about the probability of a lab leak as the origin of the pandemic, Chan said a lab origin is more likely than natural origin at this point.

We all agree that there was a critical event at the Huanan Seafood Market, that was a superspreader event caused by humans. There is no evidence pointing to a natural animal origin of the virus at that market, she noted.

Speaking on the possibility of thevirus being engineered in the lab before a leak, Chan said: "We have heard from many top virologists that a genetically engineered origin of this virus is reasonable...and this includes virologists who themselves have made modifications to the first SARS virus."

On the question of her level of confidence that the world would eventually be able to establish the true origins of COVID-19, Chan said it was simply a matter of time.

"Right now it's not safe for people who know about the origin of this pandemic to come forward. It might be five years from now, it might be 50 years from now, but we live in an era where there's so much data being collected and stored...we just need a credible, systematic investigation," she said.

"We know now that this virus has a very unique feature, called the furin cleavage site that makes it the pandemic pathogen it is. So, without this feature, there's no way this would be causing this pandemic."

"Only recently in September did a proposal get leaked showing that scientists from the EcoHealth Alliance were in collaboration with the Wuhan Institute of Virology developing this pipeline for inserting novel furin cleavage sites, these genetic modifications, into SARS-like viruses in the lab," Chan said.

According to Tory lord Lord Ridley, who has co-authored a book on the virus's origins with Dr Chan, the fact that experts have still not located the animal host that would support a natural origin despite two years of investigation, supports the notion that COVID-19 emerged from a lab.Recent discoveries of China's attempted cover-up have compelled British and US intelligence agencies to investigate the lab-leak idea seriously, which was previously regarded as a lunatic conspiracy theory.

Watch | Gravitas: Lab leak "most likely" source of Covid-19, British MPs told

The explosive charges, on the other hand, are expected to put pressure on the UK government to question Beijing's assertions that the virus originated in nature.

They're also expected to raise more questions about Chinese President Xi Jinping's connection with the WHO, which was accused last year of issuing a whitewash report on the outbreak.

Reasonable to hypothesise Covid virus is genetically engineered: Expert - WION

An international, multidisciplinary team of researchers from theTranslational Synthetic Biology Laboratoryat Pompeu Fabra University (Barcelona, Spain), led by Dr.Marc Gell, has published an article in the scientific journalNature Communicationsshowing the potential of Find Cut-and-Transfer (FiCAT) technology as a state-of-the-art tool forgene writingto develop advanced therapies that are safer and more effective in their future clinical application in patients withgenetic and oncological diseasesthat have few treatment options.

The UPF Translational Synthetic Biology Laboratory has been working on gene editing and synthetic biology applied to gene therapies since 2017. FiCAT technology is an important scientific breakthrough to overcome the current limitations of the technology used today for genome editing and gene therapy.

Human genome engineering has significantly progressed in the last decade with the development of new editing tools, but there was still a technology gap that would allow therapeutic genes to be transferred efficiently with few size limitations, comments Dr. Marc Gell, supervisor of the study.

In this work, the researchers develop an efficient and precise programmable gene writing technology based on the combination of modified proteins CRISPR-cas and piggy Bac transposase (PB), succeeding in inserting small and large fragments. Dr.Maria Pallars, co-first author of the study explains that: CRISPR stands out for its precision when editing small fragments. However, transposases allow us to insert large fragments but in an uncontrolled manner. We have combined the best of each technology.

In this way, FiCAT technology allows us to precisely insert large fragments of DNA into the genome. This means we can develop therapeutic solutions to diseases that currently have no treatment, such as Duchenne muscular dystrophy, or some cases of hereditary blindness, in which the affected gene is large in size, asserts Dr.Avencia Snchez-Mejas, a senior researcher with the group and co-supervisor of the work.

They tested the technology in human and mouse cell lines achieving efficiencies of 522% with minimal off-target insertions and have demonstrated on-target gene transfer in vivo in mouse liver and germline cells in mouse models. Lastly, they performed a directed evolution of FiCAT and further improved efficiency by 25-30%. We have been progressively modifying enzymes so that they acquire the function we were looking for, selecting the ones that displayed a better function, detailsDimitrije Ivani, co-first author of the article. Our work is a clear example that enzyme engineering in the context of genome editing has great potential, he concludes.

UPF has transferred FiCAT technology via the spinoffIntegra Therapeutics, founded in 2020 by the researchers Marc Gell and Avencia Snchez-Mejas, seeking to get this scientific knowledge and technological capacity to reach the biopharmaceutical industry to develop safe and efficient advanced technologies that reach patients. Recently, Integra Tx has obtained 4.5 million euros in funding from Advent France Biotechnology (France), Invivo Capital (Spain) and Takeda Ventures (USA).

The work published in Nature Communications was carried out with funding from the Societal challenges AEI, AGAUR- PRODUCTE, UPGRADE-Horizon 2020 of the European Commission; la Caixa CaixaImpulse Validate and CaixaImpulse Consolidate programmes; the Ramn Areces Foundation; and the Ramn y Cajal programme of the Spanish Ministry of Economy, Industry and Competitiveness.

New Gene-Writing Tool Helps To Develop Advanced Gene Therapies - Technology Networks

NEW YORKand DUBAI, United Arab Emirates, Dec. 15, 2021 /PRNewswire/ --Secondcell Bioand Alliance Care Technologies Internationaland announce new strategic partnership using Chromovert Technology to establish a novel, cutting-edge research focused on cell technology and rapid drug discovery to combat rare genetic diseases in the United Arab Emirates.

Chromovert has been extensively validated to streamline a key step of the drug discovery process by a boutique biotechnology company co-founded by its inventor, Dr. Kambiz Shekdar, PhD and the late Nobel-laureate Dr. Gunter Blobel, MD, PhD of The Rockefeller University. The present initiative aims to make revolutionary advancements by scaling-up and applying the demonstrated biotechnology to implement drug discovery at scale, with targets including CNS indications, COVID/Pulmonary Edema (ENaC), orphan and rare diseases and Thalassemia.

In the pharmaceutical drug discovery and development process, Chromovert is a cutting-edge technology that goes beyond CRISPR by enabling the creation of previously out-of-reach designer cells for improved drug discovery. The novel technology was published for the first time in March 2021 by Springer Nature: Cell engineering method using fluorogenic oligonucleotide signaling probes and flow cytometry.Founded by Dr. Shekdar,Secondcell Biobrings optimized materials and methods to operate Chromovert Technology to market.

According to Dr. Shekdar, "Our technology can have a global impact on genetics and cell research, particularly in the area of rare genetic diseases drug discovery. At this stage we want to partner with companies that are positioned to move quickly to advance current research toward finding cures. We are excited at the prospect of joining the healthcare revolution taking place in the UAE and having the opportunity to work with the best researchers from across the globe."

Alliance Care Technologies International CEO Michele Tarnow echoes those sentiments. "We have the privilege to work with the UAE's leading hospitals and research centers. By helping to bring Secondcell Bio and Dr. Shekdar's research to the UAE, we help the Emirates achieve their goal of becoming the leader in global health care by 2030. We are excited to work alongside Dr. Shekdar to bring this cutting-edge research to the UAE."

As part of the expansion into the UAE, a world class Scientific Advisory Board will be appointed to identify and prioritize additional therapeutic indications. Dr. Shekdar notes, "As whole genome sequencing of individuals and analysis by AI increases, additional drug targets will be identified, including for personalized medicine. By strategically locating in the UAE, we enhance data collection in that region and can prioritize drug discovery against new and relevant targets."

Tarnow notes additional advantages to working with Secondcell Bio and Chromovert. "In addition to the promising research advances that can be achieved, the advanced technology used to develop S4, our Syndromic Surveillance solution, has the potential to enhance Secondcell Bio data collection. We are excited to explore ways we can collaborate to improve health care across multiple sectors."

Previously, Chromovert was used to create exceedingly rare laboratory cells that accurately mimic the biology of human pain perception, resulting in the discovery and development of a novel clinical-stage pain blocker fast-tracked by the FDA and presented at The White House as part of Governor Chris Christie's panel on the opioid epidemic. The biotechnology was also the subject of a $100M+ natural flavors discovery engine implemented with The Coca-Cola Company, Kraft Foods and Nestle to create human tastebud-like cells for miniaturized turbo taste testing of natural extracts to discover exquisite natural flavors to cut sodium and sugar in the diet.

Demonstrating the breadth and range of technology, Drs. Shekdar and Blobel also established Research Foundation to Cure AIDS (RFTCA) based upon Chromovert. RFTCA is a U.S. 501(c)3 not-for-profit organization seeking to develop a global cure for AIDS by using Chromovert to increase the efficiency of promising, but stunted, investigational cell therapy strategies to cure HIV infection. Sickle Cell Disease, Thalassemia and certain other diseases also stand to benefit by the addition of Chromovert Technology.

The strategic partnership by ACTI and Secondcell aims to realize the full potential of the technology to discover and develop a pipeline of candidate drugs for diseases with unmet need. Currently, the industry average failure rate for drug discovery programs in pharmaceutical companies is reported to be approximately 98%. One key factor contributing to the high failure rate is the lack of cells that accurately mimic the biology of human disease in the laboratory dish. Chromovert Technology has been demonstrated to permit the rapid creation of laboratory cells that accurately mimic human disease, allowing for the improved discovery of candidate drug molecules with a greater overall likelihood of success.

ACTI and Secondcell Bio invite researchers, entrepreneurs and investors interested in learning more about current research, collaborations or investment opportunities to contact for more information.

This science fiction novel tells the story of how an artificial intelligence navigates a human world. Klara is an Artificial Friend, a solar-powered robot built to provide companionship to children. I was quickly transfixed by the style of Klaras first-person narration of the daily patterns of human and robot life, which provides an interesting perspective on both the potential and limitations of artificial intelligence. As the novel progresses, Klara's unique lens is trained on deeper questions regarding childhood illness, genetic engineering, social class, and what it means to love.

Eels are delicious. Thats about all I knew. This book opened my eyes to one of the worlds most fascinating creatures. I just couldnt wait to tell my wife facts after every reading. (She wasnt as keen on hearing them, especially the third or fourth time.) But you wont be able to help yourself either. Aristotle makes an appearance, as does Freud and countless others who have tried to understand eels. No one has. No one has ever seen one breed and no one really understands them. The author alternates between chapters about eels and memoirs of he and his father fishing for eels in Sweden. The factual chapters are hugely interesting; the personal ones are deeply moving, especially for fathers with sons. Youll like both types of chapters, even if you dont like eels or dont have sons.

GAITHERSBURG, Md., Dec. 15, 2021 /PRNewswire/ -- Novavax, Inc. (Nasdaq: NVAX), a biotechnology company dedicated to developing and commercializing next-generation vaccines for serious infectious diseases, today announced the submission of a New Drug Application (NDA) to the Ministry of Health, Labour and Welfare (MHLW) in Japan for its COVID-19 vaccine by its partner Takeda Pharmaceutical Company Limited (Takeda). Novavax' recombinant nanoparticle COVID-19 vaccine with Matrix-M adjuvant, known as TAK-019 in Japan and NVX-CoV2373 outside Japan, is the first protein-based COVID-19 vaccine to be submitted under an NDA in Japan.

With the support of the MHLW, the companies are working to establish the capability to manufacture TAK-019 at Takeda's facilities in Japan and aim to begin distribution in early 2022, pending regulatory approval.

"Today's submission marks further progress in our quest to ensure broad global access to our protein-based COVID-19 vaccine," said Stanley C. Erck, President and Chief Executive Officer of Novavax. "Our partnership with Takeda reflects our shared commitment to tireless collaboration to deliver a COVID-19 vaccine, built on a well-understood vaccine platform."

The NDA submission includes an interim analysis from Takeda's ongoing Phase 1/2 immunogenicity and safety clinical trial of NVX-CoV2373/TAK-019 in Japan, in which the vaccine demonstrated a robust immune response and was well tolerated with no serious adverse events. Takeda submitted all available chemistry, manufacturing and controls (CMC), non-clinical and clinical data as of December 2021. Additional CMC data will be subsequently submitted to the Japan Pharmaceuticals and Medical Devices Agency (PMDA) during the NDA review period.

The application also includes safety and efficacy data from Novavax' two pivotal Phase 3 trials: PREVENT-19, which included 30,000 participants in the U.S. and Mexico and demonstrated 100% protection against moderate and severe disease, 93.2% efficacy against the predominantly circulating variants of concern and variants of interest, and 90.4% efficacy overall; and a trial of 15,000 participants in the U.K. that demonstrated efficacy of 96.4% against the original virus strain, 86.3% against the Alpha (B.1.1.7) variant and 89.7% efficacy overall. In both trials, NVX-CoV2373 demonstrated a reassuring safety and tolerability profile.

In addition to the submission of the NDA to MHLW in Japan, Novavax and Serum Institute of India Pvt. Ltd. (SII) recently received Emergency Use Authorization (EUA) for the vaccine in Indonesia and the Philippines, and the companies have filed for EUA in India and for Emergency Use Listing (EUL) with the World Health Organization (WHO). Novavax also announced regulatory filings for its vaccine in the United Kingdom, Australia, New Zealand, Canada, Singapore, United Arab Emirates, and the European Union and with the WHO. Additionally, Novavax and SK bioscience announced a Biologics License Application (BLA) submission to MFDS in South Korea. Novavax expects to submit its complete CMC data package to the U.S. FDA by the end of the year.

About NVX-CoV2373NVX-CoV2373 is a protein-based vaccine candidate engineered from the genetic sequence of the first strain of SARS-CoV-2, the virus that causes COVID-19 disease. NVX-CoV2373 was created using Novavax' recombinant nanoparticle technology to generate antigen derived from the coronavirus spike (S) protein and is formulated with Novavax' patented saponin-based Matrix-M adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies.

SAN DIEGO, Dec. 13, 2021 /PRNewswire/ -- Poseida Therapeutics, Inc. (Nasdaq: PSTX), a clinical-stage biopharmaceutical company utilizing proprietary genetic engineering platform technologies to create cell and gene therapeutics with the capacity to cure, today reported interim results from its Phase 1/2 PRIME clinical trial of P-BCMA-101 for the treatment of relapsed/refractory multiple myeloma (R/R MM) at the 2021 American Society of Hematology (ASH) Annual Meeting.

The results show that P-BCMA-101, a non-viral transposon-based autologous CAR-T, was well tolerated and demonstrated strong anti-tumor activity in advanced, late line R/R MM patients. The learnings from P-BCMA-101 informed the development of the Company's first allogeneic program, P-BCMA-ALLO1 which is also being evaluated in R/R MM patients. The Company previously announced that it is winding down the P-BCMA-101 autologous program in favor of the allogeneic program, P-BCMA-ALLO1.

"We are encouraged by the outcomes seen from our clinical trial of P-BCMA-101, results that continue to validate our approach and that have informed P-BCMA-ALLO1, our first fully allogeneic CAR-T program for patients with multiple myeloma, as well as our other programs. Our focus is on creating differentiated product candidates with a high percentage of T stem cell memory (Tscm) cells," said Eric Ostertag, M.D., Ph.D., chief executive officer of Poseida Therapeutics. "Looking ahead, we continue to advance P-BCMA-ALLO1 and P-MUC1C-ALLO1 and look forward to presenting data in 2022 for both of these allogeneic programs."

The PRIME trial is a Phase 1/2, open label 3+3 single dose escalation of P-BCMA-101 CAR-T cells. The primary objective of the study is to determine the safety and maximum tolerated dose of P-BCMA-101 based on dose limiting toxicities (DLT), and the key secondary objective is to assess the anti-myeloma effect of the product. The median patient age was 62, with a median time since diagnosis of approximately 5.8 years. Patients were heavily pre-treated, with a median of 7 prior lines of therapy (2-18). As of the data cut-off date of October 15, 2021, a total of 98 patients have been dosed with P-BCMA-101.

The best observed treatment regimen was a combination with rituximab (n=14), with an overall response rate (ORR) of 78%, a VGPR/sCR rate of 43% and 100% overall survival at the time of the data cutoff. Progression free survival was also improved with rituximab, with median overall survival rates not yet reached in several cohorts including the rituximab combination cohorts. Response rates for other cohorts are consistent with results previously reported.

Across the study, no dose-limiting toxicities were observed. 28% of patients developed cytokine release syndrome (CRS) and 7% of patients developed neurotoxicity. None of the patients developed Grade 3 or higher CRS, and 2% of patients developed Grade 3 neurotoxicity. There were no treatment-related deaths among the patient population and no patients needed ICU admission as a result of CAR-T related toxicities. 28 patients were treated on a fully outpatient basis.

"P-BCMA-101 demonstrated strong anti-tumor activity in advanced multiple myeloma patients, and cohorts to date have shown minimal CRS and neurotoxicity, which allows for safe administration in an outpatient environment and combinations with other therapies," said Caitlin Costello, M.D., Associate Clinical Professor of Medicine and member of the Division of Blood and Marrow Transplantation at the University of California, San Diego. "These data indicate that the piggyBac transposon-based platform is an attractive option for allogeneic CAR-T cells, which has led to a first-in-human Phase 1 study."

The Company's first fully allogeneic CAR-T cell product, P-BCMA-ALLO1 utilizes Poseida's proprietary piggyBac DNA delivery system and Cas-CLOVER site-specific gene editing system to create an allogeneic product that prevents both graft-vs-host and host-vs-graft diseases and also incorporates a next-generation BCMA binder. P-BCMA-ALLO1 manufacturing involves a proprietary "booster" molecule that allows for numerous doses to be produced from a single manufacturing run, while maintaining desirable Tscm cells, which can reach percentages in the 60-80% range.

The Investigational New Drug (IND) application for P-BCMA-ALLO1 was given a safe to proceed designation by the FDA in August 2021. The Phase 1 study is an open label, dose escalation study following a 3+3 design of dose escalation in subjects with R/R MM. The study will assess the safety and maximum tolerated dose of P-BCMA-ALLO1 based on dose limiting toxicities. Key secondary objectives of the study include the anti-myeloma effect and safety of P-BCMA-ALLO1.

The best and most efficient way to perform multi-disciplinary research is by doing it in collaboration. One of such research programs, including synthetic biology, materials science, bioelectrochemistry, bioelectronics, and biosensors, has been performed in a close collaboration between scientists at the Department of Chemistry and Biomolecule Science, Clarkson University, Dr. Oleh Smutok, Dr. Artem Melman (deceased on November 25, 2021), and Dr. Evgeny Katz, with a team of Australian scientists led by Dr. Kirill Alexandrov, Queensland University of Technology (Figure 1). This collaboration being active for several years has been supported with grants from Human Frontiers Science Program (HFSP) and US Department of Defense with the total funding over 1 million dollars. The results from the collaborative efforts have been published in numerous scientific papers and covered by several patents. The most recent and impressive publication was a paper in Nature Communications one of the top scientific journals (Impact Factor 14.92). The paper entitled Design of a methotrexate-controlled chemical dimerization system and its use in bio-electronic devices (Nature Commun. 2021, 12 article No. 7137) reports on a novel artificial enzyme produced by genetic engineering that can be activated with a drug (methotrexate) molecules. The artificial enzyme was immobilized at an electrode surface and used for the drug biosensing with extremely high sensitivity and specificity (Figure 2).

In addition to the fundamental novelty of using the artificial signal-activated enzyme, the study is highly relevant for practical biomedical application. Methotrexate is a toxic drug used in anti-cancer chemotherapy and its overdose has serious, life-threatening side effects. Thus, the methotrexate analysis in biological fluids is important for keeping the drug at the optimal concentration. The study opens the future options for biomedical applications of the developed biosensor and possibilities for other biosensing systems based on the same concept. It should be noted that the success of this project was based on the collaboration of scientists with expertise in different areas, synthetic biology, synthetic organic chemistry, and bioelectrochemistry. This is an exemplary collaboration that serves as a model of performing multi-disciplinary research. While the artificial enzyme preparation was carried out by the Australian team led by Dr. Alexandrov, the bioelectrochemical study of the developed biosensor was performed by Dr. Smutok at Clarkson University. Both US and Australian teams are continuing their successful work combining synthetic biology and bioelectronics and are expecting many more interesting and practically important results. The scientific efforts are combined with the education of graduate and undergraduate students participating in the project.
