Initial Clinical Data from Editas Medicine's BRILLIANCE Clinical Trial of EDIT-101 for LCA10 to be Presented at the International Symposium on Retinal...

(UroToday.com)TheAmerican Urologic Association annual meeting included a State-of-the-Art Lecture by Dr. Brian Chapin who discussed personalized medicine in the management of prostate cancer across the patient care continuum. Dr. Chapin notes that the way we think about the personalized approach to prostate cancer therapy involves seeing a patient in the clinic and assessing them on a number of factors (clinical features, genetics, genomics, serum markers, receptors, induced responses, and selection pressures) and then developing a personalized approach to their treatment plan:

In setting the stage for personalized care, it is important to understand the available treatment options in the castration-nave setting, as well as the castration resistant setting:

Dr. Chapin notes that personalized care is compartmentalization by stage, histology and biology. Traditionally we have delineated care by stage of disease in combination with histologic considerations (ie. neuroendocrine, ductal, adenocarcinoma). More recently, there has become an increasingly more sophisticated approach, with regards to assessing the androgen receptor axis (TMPRSS2-ERG, SPOP, AR responsive), loss of tumor suppression (p53, PTEN, Rb), DDR mutations (BRCA, CDK12, FANCONI, CHEK1/2), and mismatch repair (MSI, Lynch syndrome).

Compartmentalization allows for better risk stratification, for example balancing arms in a clinical trial by using stratification factors (ie. M1a/b versus M1c) and balancing groups in retrospective studies by utilizing matching or propensity scoring (ie. NCDB, SEER database). However, this can also generate selection bias in retrospective cohort series, for example in patients with occult node positive prostate cancer, some patients will undergo a completion prostatectomy whereas others will have their radical prostatectomy aborted (thus, unable to compare outcomes). Many of us think of personalized care in prostate cancer by way of DNA, RNA, proteins and receptors, such as in the pre-biopsy, post-biopsy, positive biopsy, post-radical prostatectomy, and metastatic settings:

Dr. Chapin emphasizes that it is critically important to delineate between prognostic versus predictive biomarkers. Prognostic biomarkers are a variable associated with favorable or unfavorable outcomes for patients in the absence of treatment. Predictive biomarkers are a variable used to identify patients or groups of patients most likely to benefit from a specific therapy, for example a patient with a DNA damage repair mutation being a candidate for PARP inhibitor treatment, or a patient with a mismatch repair deficiency being a candidate for anti-PD1 antibody treatment. Prognostic variables can be used incorrectly thus mistakenly influencing management. For example, genomic tests on prostate biopsies have all been based on treated prostate cancer patients, thus these findings may not be applicable to an active surveillance cohort. Findings from these genetic tests are used to make changes in management decisions, resulting in Medicare approval. Dr. Chapin states that it is important to remember that no randomized trials have reported outcomes (although there are several ongoing) assessing if genomic tests improve patient outcomes, and in fact reflexive genomic testing may be detrimental to patients.

Dr. Chapin then discussed several potential predictive markers and prospective trials. The PAM50 gene expression classifier was previously described in the breast cancer literature, but has since been applied to prostatectomy specimens. Zhao et al.1 applied the classifier to 3,782 samples (1,567 retrospective, 2,215 prospective) noting that the PAM50 classifier consistently segregated prostate cancer into three subtypes in both retrospective and prospective cohorts:

Luminal A, luminal B, and basal curves separate based on PAM50 gene expression, with basal tumors having worse prostate-cancer specific survival:

When assessing luminal B and basal tumors with regards to response to ADT, this study suggests there may be a benefit to treatment of luminal B patients with ADT but no benefit seen in those with basal tumors:

Another example is the post-operative radiation therapy outcomes score (PORTOS), which is a genetic prediction score for post-op radiation. PORTOS is made up of 24 genes selected from a training set of 196 men and validate in a separate cohort of 330 men, with a clinical endpoint of metastasis over 10 years of follow-up.2 In this study, patients with a high PORTOS score had a benefit in cumulative incidence of distance metastasis with radiotherapy (HR 0.15, 95% CI 0.04-0.60), whereas patients with a low PORTOS score (HR 0.92, 95% CI 0.56-1.51) did not have a benefit with radiotherapy:

Biomarker examples have also been described in the advanced prostate cancer setting, specifically assessing androgen indifferent or aggressive variant prostate cancer. In a phase 1-2 trial assessing cabazitaxel plus carboplatin for men with mCRPC, at a median follow-up of 31.0 months, combination cabazitaxel plus carboplatin improved the median progression-free survival from 4.5 months (95% CI 3.5-5.7) to 7.3 months (95% CI 5.5-8.2; HR 0.69, 95% CI 0.50-0.95) with cabazitaxel alone.3 Dr. Chapin notes that what is particularly interesting is that for patients with a positive aggressive variant prostate cancer molecular signature, there was an improvement in overall survival with the addition of platinum based chemotherapy, whereas there was no benefit in those that were aggressive variant prostate cancer molecular signature negative. Dr. Chapin highlighted that there are several trials ongoing in the localized setting assessing a personalized approach, including the Genomic Umbrella Neoadjuvant Study (GUNS):

Decipher is a 22 gene classifier that provides risk stratification based on radical prostatectomy specimen analysis, which is prognostic for metastasis. However, there is no data on predictive ability, which is undergoing prospective evaluation in the NRG-GU009 PREDICT-RT trial:

Importantly, there are several barriers to overcome in the era of personalized medicine, including (i) assessing if findings are transferrable across stages of the disease; (ii) tumor heterogeneity, whether intertumoral, intratumoral, or comparing a metastases to the primary tumor; (iii) in order to move from prognostic to predictive markers, prospective trials are required; (iv) it is important to determine drivers in the setting of co-occurences (ie. DDR, +/- p53, +/- Rb1, +/- PTEN); and (v) assess selection pressures over time (ie. the predominant clone).

Dr. Chapin concluded his presentation with the following take-home messages from his presentation of personalizing medicine in the management of prostate cancer:

AUA 2021: State-of-the-art Lecture: Personalized Medicine in the Management of Prostate Cancer Across the Patient Care Continuum - UroToday

iECURE is emerging from stealth with $50 million and a mission to go after the "holy grail" of gene editing with an in vivo approach that is mutation agnostic.

The biotech will use the funds for a slate of gene insertion programs for liver disorders out of the lab of gene therapy pioneerJim Wilson, M.D., Ph.D. at the University of Pennsylvania.

Versant Ventures, which has backed gene-editing companiesCRISPR Therapeutics and Graphite Bio,is launching iECURE alongside OrbiMed Advisors. The series A gives the biotech access to up to 13 programs out of Wilson's Gene Therapy Program at Penn.

Wilson's lab will conduct the preclinical, toxicology and manufacturing supportand then iECURE will sign the regulatory filings and move the assets through the clinic and onto the market, CEO JosephTruitt told Fierce Biotech.

Its a much more mature company than you would typically start off with if you were just licensing some technology from an academic center," Truitt said. By getting access to Wilson's team, iECURE doesn't have to recruit dozens of employees, the CEO said.

Wilson's lab has already shown long-term evidence of genome editing in non-human primates, which is important because translating into species larger than mice is often difficult, said Tom Woiwode, Ph.D., iECURE chairman and Versant managing director, in a joint interview with Truitt and Wilson.

Wilson has thought of the liver as a great target for gene therapy since the late-1980's, when he was in the lab as a post-doc, because "so many diseases have their root in the liver [and] it's accessible to biologics." Wilson is also director of the Orphan Disease Center and a professor in medicine and pediatrics at Penn's School of Medicine.

iECURE and Wilson's lab are approaching the "holy grail of genome editing" by using an in vivo approach that inserts genes inside organs, inside the human body, Woiwode said. In another adventurous analogy,Woiwode said the company is also going after the "untapped frontier of gene editing" by using a mutation agnostic approach. This is critical given many genetic diseases have multiple, "sometimes hundreds," of individual mutations. That many targets would not lend well to creating therapies at scale, the chairman added.

The series A will help iECURE bankroll the first three indications in the program of up to 13, Truitt said. More indications down the pipeline are still under evaluation. The financing is slated to take iECURE through the early part of 2023, the CEO said.

The first program goes after familial hypercholesterolemia, or high cholesterol caused by abnormalities in the gene PCSK9. The treatment reduced PCSK9 protein levels by 85% and LDL cholesterol by 56% in nonhuman primates for three years, Wilson's lab reported in Molecular Therapy in February.

The lab has been working with Precision Biosciences on that asset, which is ready to enter the clinic.As part of iECURE's deal with Wilson's lab, iECURE will conduct the phase 1 study and then return the program to Precision, Truitt said.

The next two indications in the pipeline are the rare metabolic disorders phenylketonuria and ornithine transcarbamylase deficiency, Truitt said.

The gene-editing technology used by iECURE and Wilson's lab is delivered viaadeno-associated virus, or AAV. Toxicity and safety issues have arisen with AAV gene therapies, which resulted in an FDA advisory committee meeting last week to discuss and make recommendations on animal and human testing with these therapies.

Wilson took part in two panels during thetwo-day meeting and said he doesn't see the results of that meeting having an impact on iECURE.

"In terms of the work with IECURE, there really isnt anything that I heard at the committee that impacts on our preclinical plan, our clinical plan or our discussions with health authorities," Wilson said.

Researchers have discovered a specific gene that drives much of the development of the stripes, blotches, and spots that decorate cat fur with patterns.

Color patterns are one of these unsolved biological mysteries; theres no go-to model organism to study itmice dont have stripes or spots, says Gregory Barsh, professor emeritus of genetics at Stanford University School of Medicine.

The color patterns and variability that you see in animals like tigers, cheetahs, and zebras prompted some central questions for us: What are the developmental genetic mechanisms and the cellular mechanisms that give rise to these patterns and how have they been altered during mammalian evolution to give rise to the amazing diversity of shape and form we see today?

Barsh and his team have answered part of that question: They have identified a gene, DKK4, that helps regulate the early development of the different fur patterns in domestic cats. DKK4, the team suspects, is likely involved in color patterns in all cats and perhaps other mammals, too.

The researchers findings appear in Nature Communications. Barsh is the senior author. Research scientists Christopher Kaelin and Kelly McGowan are co-lead authors.

The researchers previously identified a different gene that controls coat color variation in tabby cats. Its the same gene that accounts for the difference between cheetahs and king cheetahs, which have thicker, more prominent fur patterns.

We knew from studying domestic cats that there were other genes that contributed to color pattern formation; we just didnt know what they were, Barsh says.

They found a clue in fetal cat tissue that seemed to foreshadow fur color: a thickening of the skin tissue in certain areas. These thickened regions constitute a prepattern that mimics the eventual color patterns in an adult cats fur. The thick area marks the patches of fur that will later be darker; the thin area marks the patches that will be lighter.

We call this step establishment, and it happens long before color appears and long before hair follicles are mature, Barsh says.

The prepattern provided a map of sorts for the researchers, indicating cells involved in creating the pattern and the time when the pattern formed. The researchers then inspected the genetic makeup of individual cells in the thick and thin regions of skin. DKK4 was particularly active in the thickened skin, but not in skin that had remained relatively thin.

But to really lock in the connection between DKK4 and early pattern formation, the team turned to the Abyssinian cat. Abyssinians are known for sporting a blur of colors in their coat, with tiny, darker markings squished together, as if someone used a pencil to lightly shade a layer of gray on top of their orangish-brown coat. Barsh and his team identified disrupting mutations in the DKK4 gene responsible for the Abyssinian cats apparent lack of tabby markings, a look thats called ticked.

If you remove DKK4, the dark areas dont go away entirely, but they become smaller and more packed together, Barsh says.

You may be wondering, what about all-white cats? Or all-black cats? They, too, are patterned underneath their monochrome swath of fur. There are two distinct processes that make a color pattern: One that forms the pattern during embryonic development and one that translates the pattern into pigment produced in hair follicles. In solid-colored cats, the pattern is essentially overridden by instructions to produce dark pigment everywhere. In white cats, the pigment is lacking.

Scientists dont know exactly how DKK4 paints the array of color patterns domestic cats sport, but they do know DKK4 interacts with a class of proteins called WNTs, which are crucial in early development. WNTs and DKK4 help to form a prepattern when embryos are only two or three millimeters in length, weeks before pigment is produced in hairs. DKK4 is involved in marking areas that will eventually have darkly pigmented hairs, Barsh says, but how these skin areas remember their fate to induce target pigment is unclear.

This is one of the big unanswered questions in our workhow to connect the process of prepattern formation to the process that implements the pattern later in development, he says. Thats something that were actively trying to figure out.

On top of that, DKK4 is only part of the answer to the mysterious genetics dictating fur patterns. There are still other genes that are behind why, for instance, some cats have spots and why some cats have stripes, Barsh says. Looking into that is on their list, too.

Funding for the work came from the HudsonAlpha Institute for Biotechnology and the National Institutes of Health. Stanfords genetics department also supported the work.

Orchard Therapeutics Bolsters R&D and Technical Operations Leadership with New Executive ... - The Bakersfield Californian

PHILADELPHIA, Sept. 09, 2021 (GLOBE NEWSWIRE) -- Scout Bio today announced the successful completion of a CKD-associated anemia study in client owned cats treated with SB-001, an AAV expressing feline erythropoietin (fEPO). The study demonstrated a prolonged therapeutic effect with statistically significant increases in red blood cells after a single injection. SB-001 is the first gene therapy to successfully treat feline patients with an acquired non-monogenic disease. These results pave the way for Scout Bios portfolio of AAV delivered therapeutic proteins for companion animal diseases.

Clinical Study Highlights:

In this study we have successfully shown that SB-001 has the ability to increase PCV into the normal range, thereby reducing or eliminating the clinical effects of anemia associated with CKD, said Mark Heffernan, Ph.D., CEO of Scout Bio. These exciting results reinforce the potential for Scout Bios gene therapy platform to advance treatments for other acquired chronic diseases such as diabetes, chronic pain and atopic dermatitis.

There are no FDA-approved treatments available for CKD-associated anemia in cats. The single injection treatment of SB-001 presents an enormous advantage in convenience, improved compliance, and potentially allows owners more quality time with their pets. A new option for cats with kidney disease and anemia is urgently needed. These cats come into the veterinary clinic with weakness, lethargy, breathing difficulties, and overall feeling very unwell. SB-001s ability to increase the PCV can make a huge difference for many of these cats that would otherwise face euthanasia, said Anne Traas, DVM, MS, DACT, Chief Development Officer for Scout Bio and head of the clinical team leading the study. It was very rewarding to hear from owners participating in the study who expressed their deep gratitude for the additional time SB-001 was able to provide their beloved pets.

James M. Wilson, MD, PhD, Director of the Gene Therapy Program at the University of Pennsylvaniaand a co-founder of Scout Bio, commented, Scout Bios focus in companion animals with chronic diseases has resulted in this successful demonstration that AAV gene therapy can be an effective alternative to frequent injections with therapeutic proteins and result in the improvement of feline patient lives. These results provide validation that Scout Bios platform can be used to successfully deliver therapeutic proteins to treat chronic diseases in companion animals.

Scout Bio intends to progress key manufacturing activities and safety studies that will be necessary to apply for Expanded Conditional Approval under FDA guidelines.

About SB-001 SB-001 has a unique and innovative adeno-associated viral (AAV) vector, containing the gene for feline EPO, for delivery into the muscle cell nucleus which will continually produce therapeutic levels of the hormone. The expressed feline EPO stimulates erythropoiesis, or red blood cell production. The U.S. Food and Drug Administration (FDA) CVM has confirmed that SB-001 is eligible for Expanded Conditional Approval, potentially shortening the time until this product could be approved and made available.

About Chronic Kidney Disease (CKD)-Associated AnemiaAnemia associated with chronic kidney disease (CKD) in cats is a disease of high unmet medical need, with no FDA-approved therapies currently available. CKD is one of the most common diseases in senior cats and is an end-of-life disease that creates quality of life issues for cats and their owners. Up to 21% of cats with CKD have anemia and the only currently available therapeutic options are multiple blood transfusions or repeated injections of off-label human drugs. Compared to the off-label use of human EPO drugs, SB-001 is expected to have a superior safety profile with respect to immune reactions and incidence of pure red cell aplasia (PRCA), a serious life-threatening condition.

Scout Bio Successfully Completes Pilot Clinical Study of SB-001, a Single-Injection AAV Gene Therapy - GlobeNewswire

For the first time, doctors have partially restored the vision of a completely blind French man using light-sensing algae proteins. The breakthrough marks a significant milestone in genetic blindness treatment.

The man was diagnosed with the rare, genetic eye condition retinitis pigmentosa (RP) which causes the death of light-sensing cells on the retina forty years ago. The condition affects over two million people worldwide, and while complete blindness is rare, the man has had no vision for the past twenty years.

The French man, whose identity has not been revealed, was treated with optogenetics therapy, which uses the algae proteins to control cells at the back of his eye. He first realized the treatment was working when he could see the painted stripes of a crosswalk. Impressively, he can now count and grab objects too!

According to the study published on May 24 in Nature Medicine, this is the first reported case of partial functional recovery in a neurodegenerative condition after optogenetic therapy.

Optogenetics is a standard tool in fundamental neuroscience research, but its new to the world of medicine. It works by using light to activate specific brain cells and was used by the doctors in France to restore one of the mans eyes to detect light.

In his case, the light-detecting cells in his retina had died off a long time ago; therefore, the doctors inserted an algae gene into the surviving cells of the retina at the back of his eye. This caused them to produce channelrhodopsins, a protein found in algae that helps the photosynthetic microbes move toward light sources. In other words, now, when they are hit with light, they will send an electrical signal directly to the brain.

Since theres a big difference between photosynthetic algae and the human eye, the new therapy has limitations. It didnt restore the mans vision to normal levels and didnt allow him to see in color. However, they would respond to amber-colored light.

To solve this problem, the patient wore special goggles with a video camera and projector to capture the real world and translate a version in the correct wavelength onto the back of his eye, allowing him to see.

After months of training and building up high enough levels of the rhodopsins in the eye, the mans brain finally learned how to see again, starting with the white stripes of a pedestrian crossing.

Dr. Jos-Alain Sahel, who treated the patient at Pariss Institute of Vision, said:

This patient initially was a bit frustrated because it took a long time between the injection and when he started to see something. But when he started to report spontaneously that he could see the white stripes across the street, you can imagine he was very excited. We were all excited.

Not only did the patient report identifying the crosswalk, but that he could count the number of white stripes too! After more training, the patient displayed a significant improvement in daily visual activities, including detecting a mug, plate, phone, furniture in a room, or a door in a corridor, but only while using the goggles. Therefore, treatment by combining an optogenetic route with light-stimulating goggles led to a decent level of visual recovery.

While the mans eyesight isnt perfect, the difference between no vision and limited is a life-changer. The findings provide proof-of-concept that using optogenetic therapy to partially restore vision is possible, concluded Prof. Botond Roska from the University of Basel.

James Bainbridge, a retinal studies professor at the UKs UCL, said:

This exciting new technology might help people whose eyesight is very severely impaired.

Researchers are also exploring optogenetic therapy for conditions like Parkinsons disease to see whether it can improve recovery from a stroke.

In recent years, scientists have developed several approaches to restore sight. One includes correcting the genetic defects that cause RP, a challenging task since the disease has a significant number of mutations in over 71 different genes. In 2018, scientists at Oxford University in the UK completed a first gene therapy trial, improving patients vision for Choroideremia (one of the many forms of RP) by injecting a single healthy gene into their eyes. Their results were published in Nature Medicine.

Algae Gene Therapy Partially Restored Completely Blind Man's Vision - Intelligent Living

On September 1, 1971, unknowingly to most, the world changed for the fields of behavioral genetics and circadian clocks. Ronald Konopka, a graduate student with Seymour Benzer at Caltech, published a paper (1) that I would argue is the most important discovery ultimately leading to our current molecular understanding of the circadian clock in animals. In this classic paper, Ron and Seymour reported the isolation of three single-gene mutants in Drosophila that dramatically altered circadian rhythms in pupal eclosion and locomotor activity. One mutant exhibited no rhythmicity, another had a short 19-h period, and a third had a long 28-h period. Remarkably, all three mutants mapped to the same locus on the X chromosome. They named this gene period.

Seymour Benzer had recently joined the faculty at Caltech in 1967, after two previously successful careers in physics and molecular biology, and spurred on by Max Delbruck to do something more interesting, launched his third career in behavioral biology (25). Having done a sabbatical at Caltech with Roger Sperry, Seymour interacted with Ed Lewis, a giant in Drosophila genetics who trained with Alfred Sturtevant (descendent of Thomas Hunt Morgan) (6). Seymour chose Drosophila as a model system because its nervous system was intermediate in complexity between a single neuron and the human brain yet exhibited complex behavior and was amenable to genetic analysis (7). That same year, Seymour published his first paper (8) using mutagenesis and countercurrent technology to isolate phototaxis mutants in Drosophila. The opening sentence of this paper reads, Complex as it is, much of the vast network of cellular functions has been successfully dissected, on a microscopic scale, by the use

In many ways, Shang-Chi and the Legend of the Ten Rings, Marvels latest mega-blockbuster, is following in the footsteps of Black Panther. The 2018 installment of the MCU opened the door for Black representation in blockbuster cinema, and walked all the way to the Oscars. It took an even longer time for Marvel to get to a point where Shang-Chi could fill that role for Asian audiences.

The history of the character is far more complicated and messy than the movies production timeline. Originally, Shang-Chi was an extension of Marvels licensing deal for the problematic British literary villain Fu Manchu created by white author Sax Rohmer. Stereotypes abounded in the original Shang-Chi comic books, which had to be resolved in order for Marvel to bring this character into the 21st century. One of the people responsible for that transformation is this weeks guest on Galaxy Brains, Gene Luen Yang. Yangs credits include the graphic novel American Born Chinese, several Avatar: The Last Airbender comics, DCs Superman Smashes the Klan, and most recently, an ongoing Shang-Chi book for Marvel Comics.

To rethink Shang-Chi for the modern Marvel universe, Yang brought traditional Chinese mysticism and cultural heritage to the characters backstory. For our Shang-Chi episode of Galaxy Brains, we asked the cartoonist and writer to dig into the history of Shang-Chi, his familial relationship to Fu Manchu, and how he was able to reclaim this character for Asian communities around the world. Heres an excerpt:

What were the origins of this character and why was it not a character that was in regular rotation in the Marvel Comics universe?

Gene: I began reading Marvel Comics in the 1980s back when I was in fifth grade. I bought my very first comic from a spinner rack at my local bookstore. And back then there were some Shang-Chi comics that were around. I think his monthly series had recently ended at issue 125. So they were in back-issue bins. But as a Chinese-American kid, I was going through this thing where I just didnt want to be Asian.

So I actively avoided picking up those Shang-Chi comics. So I didnt know a ton about the character. I didnt read any Shang-Chi comics until I was an adult. But from doing research in order to write the ongoing series, he began with ... not-so-awesome origins. In the original run, he was the son of Fu Manchu. My understanding was that Marvel wanted to do a comic based on Kung Fu, the television series, but were unable to acquire the license. So getting the Fu Manchu license was the next best thing. And they created this character who was the son of Fu Manchu. If you read those early comics, there are really fun things about them the way they do action is amazing. But then the character himself, Shang-Chi himself, doesnt totally fit the Marvel mold. Like when you think of Marvel, at least when I was a kid, one of the things that I loved the most about Marvel was that the characters were meant to be relatable. Like you got to see Spider-Man go to his local laundromat to do his laundry and you identify with him. But those early Shang-Chi comics were structured that way. They werent structured in a way where youre meant to identify with.

I think about Black Panther, and how it played a similar role in the MCU to what Shang-Chi is playing now, but the Black Panther comic books were very unique in that period of the Marvel Golden Age because he wasnt a Peter Parker, a kid whos trying to scrape by and make something of himself. This character of Black Panther is a king. You know, hes very regal; TChala is not like us. Hes not relatable in that way. They found a way to make him relatable in the films, but it wasnt quite as connected and grounded to the real world as some of the other Marvel comics. Im interested to hear you say that about Shang-Chi, that it was similar in that it was, I wouldnt say othering because that seems like a negative word, but its certainly different from how grounded the Marvel superheroes were.

Gene: Yeah, thats right. For TChalla, it took awhile for them to kind of Marvel-ize him, to make them fit into what makes Marvel unique. To build in those identification pieces.

I want to drill down into Fu Manchu. For those who dont know what Fu Manchu was, or the reason why its offensive to a lot of Asian people, can you explain kind of what this character was and what his place in the popular culture was at that time?

Gene: Fu Manchu is what we would recognize as the prototypical Yellow Peril villain. Yellow Peril villains were a trend in the late 1800s, early 1900s of Western media portraying these Chinese characters, predominantly Chinese characters, as pretty inhuman. Like Fu Manchu was a Chinese super genius whos bent on taking over the Western world. He had bright yellow skin, he had really exaggerated facial features, hair, pointed ears. An early Asian stereotype was that Asians had pointy ears. I have no idea where this came from! Like, Ive never met an Asian person with remotely pointy ears. But in any case, Fu Manchu starred in these early novels written by an author named Sax Rohmer. The way I see Fu Manchu now is that I think of him as almost like a ghost. Hes not actually a ghost in the stories, but often ghost stories are a supernatural way of talking about people wrestling with their sins. The ghost in a ghost story often represents an embodiment of the repercussions of sin.

Fu Manchu became really popular towards the end. Like, I think he debuted right after what the Chinese call their century of humiliation. So during the 1800s, China as a nation just went through hell. They lost war after war and one of the one of the big wars that they lost was the Opium War against the British. And the Opium War was about Britain fighting for their right to sell drugs to the Chinese populace, which the Chinese government didnt want. And they were doing that in order to even out a trade deficit. So I think deep down inside, the Brits knew that this was a bad thing. I think deep down inside the new right, theyre sinning against this other nation. In a lot of ways, the way I read Fu Manchu is that he kind of represents the repercussions of Britains actions towards the Chinese in the 1800s. And when Fu Manchu gets defeated in those early Fu Manchu stories, its sort of like the Brits writing the story about how theyre able to put off the repercussions of their own sins.

Right now youre personally responsible for revamping the origin story of Shang-Chi. And I was wondering if you could talk us through how you approach this new story and what new details you added to the characters backstory?

Gene: Yeah, its been a ton of fun to work on. Ive gotten to work with some amazing artists. Dike Ruan and I are now doing the monthly ongoing series for the limited series that came out about a year ago. Dike did part of the art and Phillip Tan did another part. The whole things being edited by Darren Shan, an amazing editor with amazing instincts. Were all of Chinese descent and, early on, we talked about what this character meant to us. And all of us had that weird relationship that I talked about earlier, where we didnt fully embrace Shang-Chi as kids. So ultimately, what we wanted to do was bring more Marvel into this character. We wanted to make him more of a character that we could all relate to regardless of our readers cultural background. We wanted them to be able to relate to Shang-Chi.

The Marvel Universe is different from DC. Like with DC, you sometimes have these hard resets of the entire universe that happened with Crisis on Infinite Earths in the 80s, and its happened again more recently with New 52. But Marvels never gone through something like that. Marvels never had a hard reset. So it means that all the stuff in the Marvel past, like the Marvel history, is still in play, which means we have to kind of figure out how to talk about all the problematic pieces of Shang-Chi without doing a hard reset. We kept the fact that Shang-Chis dad is a supervillain. Hes no longer Fu Manchu, but hes the super villain. We tried to make his supervillain dad more sympathetic, but we wanted to lean into a family drama. Everybody can relate to family drama. So we wanted to lean into the tension between him and his dad, and we also wanted to give them a bunch of siblings that he could both support and squabble with.

That family dynamic and the idea of squabbling, I think, is probably the most unifying aspect of the Marvel Universe, both on the page and on the screen. How are you going to improve upon your parents or how are you going to overcome the obstacles presented by your parents? Theres just so much that is there in these stories. Was that something that when you were reading the comics as a kid you related to or was it something that was more just like subtext that you got later on when you grew up?

Gene: Oh, yeah, absolutely. I dont know if I would have been able to articulate it as a kid, but that was definitely something that I was drawn to. My favorite Marvel book when I was little, like when I was in elementary school, was Fantastic Four. The whole thing was about how these people love each other, but kind of hate each other sometimes, too. Thats almost all of us, the way we feel about our families. We love them. But sometimes, you know, sometimes maybe not.

Theres a big plot point in your comics about the spirit of Shang-Chis father and a jiangshi, which is a vampiric ghost-like creature from Chinese mythology and folklore. Im wondering what other elements of Chinese mythology that you worked into these comics and why did you choose to tie in those specific characters, creatures and themes?

Gene: In a lot of ways, all of the work that Ive done in comics has been about connecting with my own cultural heritage. I was born and raised in the United States, so I really only knew about Chinese culture through my parents. I remember visiting China for the very first time as an adult when I was in my 20s, and it was just weird. It was like seeing all the stuff for the first time that I had only known through echoes. So in a lot of ways my work on Shang-Chi is like trying to figure out all of this stuff. Its kind of like a selfish reason! But I just want to figure out these parts of myself.

So one of the big pieces that we used from traditional Chinese culture is this idea from traditional Chinese medicine called the five elements. You know how there are four elements of Western culture air, water, earth and fire but in Chinese culture, there are five elements: fire, earth, metal, water and wood. And what we did was we had Shang-Chi come from ... his family runs this organization called the Five Weapons Society, and the five weapons correlate with the five elements of traditional Chinese medicine.

So what was that experience like? Did you go to a theater? Did you try to make it an event for yourself?

Gene: Yeah, it was amazing. I went with a friend of mine who is also a cartoonist and we sat in that theater for a whole two hours when I watched the trailer after it dropped a few months ago, I had this feeling. I dont even know how to describe it. But basically the movie was that same feeling. For two hours, it was amazing. All the expectations that I had going in were exceeded. My friend, hes just like the prototypical nerd, before we went into the movie was like If this is good, Im going to go by all the action figures. And the first thing he did after we exited the theater was he went to GameStop and bought all the action figures..

Thats awesome. I can think back to how I felt seeing Black Panther and how a lot of people of African descent felt seeing that for the first time. And it was like, Oh, my God, I cant believe they made this thing. And I had to go out and buy all the toys.

In addition to your writing, your comics writing, you are a teacher in the Bay Area and youve merged these two careers with an online comic book for teaching math called Factoring with Mr. Yang and Mosley the Alien. How effective do you find comic books to be is teaching tools?

Gene: I think comics are an amazing tool for education. I was a high school teacher for 17 years at a high school in Oakland, and I also got my masters in education. So for a final masters project,I did that online interactive comic teaching factorials, the topic from algebra.

Dont make me remember algebra two. Im breaking out in hives.

Gene: Youre breaking out in hives because the teacher didnt use comics to teach you! For a really long time, the educational establishment avoided comics. There was this book that came out in the 1950s called Seduction of the Innocent that argued that comics cause juvenile delinquency. So even though that book was wrong, it had a huge cultural impact. And educators just avoided comics for decades. Thats changed recently, but in my research for my masters program, what I found was that, out of all of the visual storytelling media like film and television and animation comics is the only one where it puts control over time in the hands of the reader. A comic can go as fast or slow in the readers mind as the reader desires. That is an incredibly effective tool. And I think thats one of the most powerful things about comics. Theres no other visual media that allows you to do that. Its only comics.

Rethinking Shang-Chis problematic origins in the Marvel universe - Polygon

Doctors regard amyloid plaque lodged between the brains nerve cells and tangled tau protein fibers forming within the cells as the hallmark of Alzheimers disease.

However, amyloid plaque consisting of broken pieces of protein that clump together is also present in the brains of older adults who do not develop Alzheimers, suggesting another factor is triggering the disease.

A new study finds that inflammation in the brain drives the progression from the presence of amyloid plaque and tau tangles to the onset of dementia and Alzheimers disease.

Lead author of the study, Dr. Tharick Pascoal, Ph.D., assistant professor of psychiatry and neurology at the University of Pittsburgh School of Medicine, PA, explains:

Many [older adults] have amyloid plaques in their brains but never progress to developing Alzheimers disease. We know that amyloid accumulation on its own is not enough to cause dementia our results suggest that it is the interaction between neuroinflammation and amyloid pathology that unleashes tau propagation and eventually leads to widespread brain damage and cognitive impairment.

The study appears in Nature Medicine.

While scientists have observed neuroinflammation in people with Alzheimers before, the new study reveals for the first time its critical role in the development of the disease.

The research finds that activating the brains immune cells its microglial cells promotes the spread of tangled tau proteins that comprise amyloid plaque.

Heather M. Snyder, Ph.D., Alzheimers Association vice president of medical and scientific relations, who was not involved in the study, explained the purpose of neuroinflammation to Medical News Today. The Alzheimers Association contributed funding to the research.

Inflammation has an important role in fighting off infection and other pathogens in the body, including in the brain and central nervous system, said Snyder. Microglia help clear debris (damaged neurons, infections) from the brain.

However, adds Dr. Snyder, a sustained inflammatory response, or a change from acute to chronic neuroinflammation, may contribute to the underlying biology of several neurodegenerative disorders.

Inflammation is not by itself associated with cognitive impairment, Dr. Pascoal told MNT. However, he said, when neuroinflammation converges with amyloid pathology, the interaction potentiates tau pathology. As a consequence, the coexistence of these three processes in the brain amyloid, neuroinflammation, and tau pathology determines cognitive deterioration.

While experiments using cultured cells and laboratory animals have previously implicated microglial activation in the spread of tau fibers, the new study is the first to document their relationship in living people.

The researchers used MRI and PET scans to study 130 people across the age and Alzheimers disease spectra, observing the presence and extent of microglial activation, amyloid plaque, and tau tangles.

Successfully controlling neuroinflammation as a means of treating Alzheimers disease remains a challenge. Dr. Pascoal told MNT: Several different anti-inflammatory drugs can potentially reduce neuroinflammation. However, some of them have already been tested in clinical trials aiming to mitigate cognitive decline but failed.

However, he suggested, the issue may be the timing of treatment.

Our study indicates these anti-inflammatory drugs would present optimal efficacy at a specific moment in the course of the disease when the patients have tau pathology confined to the medial temporal brain cortex, he says.

Thus, says Dr. Pascoal, our results suggest that the combination of anti-amyloid with anti-inflammatory therapies in the early stages of the disease, when the pathology of tau is still confined to the temporal cortex, would maximize the efficacy of these drugs.

Snyder noted, The Alzheimers Association, through its Part the Cloud initiative, is focused on accelerating findings from the laboratory, through trials, into possible therapies filling the gap in Alzheimers drug development by supporting early phase clinical studies.

She reported, Scientists around the world were invited to submit proposals that could translate into human trials of treatments targeting neuroinflammation, with the goal of improving cognition in individuals with neurodegenerative diseases. The initiative selected four projects.

For Dr. Pascoal, the research is personal, he tells UPMC:

As a young resident neurologist in my home country of Brazil, I noticed that many patients with Alzheimers disease are left neglected and without access to appropriate care.

The studys finding gives him hope for those people. He says, Our research suggests that combination therapy aimed to reduce amyloid plaque formation and limit neuroinflammation might be more effective than addressing each pathology individually.
