Science has come a remarkably long way, especially since sequencing the human genome, but has it come far enough for everyone? A focus of TGen research has always been finding a path to the clinic and ensuring the work is relevant to all ethnicities, ages and genders. But that’s not always easy. "Right now, precision medicine is not precise for every American, and especially it's not precise for those that are of non-European ancestry," says Jeffrey Trent Ph.D., F.A.C.M.G., TGen's Founding President and Research Director, on episode 39 of TGen Talks, who discusses a new project that comes at a time where the focus on diversity in our population should be represented more significantly in our research and healthcare system. He also explains how investigators at TGen headquarters continued their research into various cancers and other diseases without missing a beat while most of the world was on COVID lockdown, and shares his views on the value of having summer interns. All this and more on TGen Talks.

×What if the cure for diseases like Alzheimer’s or cancer lay hidden inside the immune systems of llamas, cows, or even sharks? On this episode of TGen Talks, TGen’s newest faculty member, Dr. John Fryer, introduces us to the world of nanotherapeutics—a new class of biologics derived from the unique immune systems of animals like camels and sharks. These ultra-small molecules, known as “nanobodies,” are revolutionizing the way we think about treating diseases like Alzheimer’s, cancer, and even sepsis. Dr. Fryer explains how these tiny molecules—about 10 times smaller than traditional monoclonal antibodies—can target tough-to-reach areas like the brain, offering new hope for conditions once thought impossible to treat. He dives into his team’s work on neurodegenerative diseases, sepsis, and cancer, and shares how the collaboration between TGen and City of Hope is accelerating the development of these next-generation therapies.

Scientists have long known that farm chemicals can be harmful to human health. Many lawn and garden products used by consumers carry warnings, so that users can protect themselves when applying herbicides in their own yards. But which chemicals are the most dangerous? And how much exposure is too much to be considered safe? A new study from TGEN and Arizona State University is shedding light on glyphosate, a common chemical in many herbicides, and its findings indicate that not only does glyphosate cross the blood brain barrier, but its damaging effects on the brain can remain long after the exposure. Patrick Pirrotte, Ph.D., and colleagues at Arizona State University have identified an association between glyphosate exposure and symptoms of neuroinflammation, as well as accelerated Alzheimer’s disease-like pathology. The study tracks both the presence and impact of glyphosate’s byproducts in the brain long after exposure ends, showing an array of persistent, damaging effects on brain health. Listen as Dr. Pirrotte discusses the methods used in the research and how the pervasive use of such chemicals means that most Americans, even those who have no exposure to farms or the application of such herbicides have traces of the harmful compounds in their bodies.…

Listen as Jonathan Keats, Ph.D., the study's senior author discusses the findings, their impact on personalized medicine, and how TGen's advanced genomic sequencing is paving the way for more effective and individualized care. In particular, the study has identified a high-risk subgroup of patients with a distressingly short median survival, highlighting the urgent need for tailored therapies and innovative clinical trials.…
Aging. It’s something we’d all like to do better. Americans spend an estimated $5 Billion on anti-aging products every year. But at TGen and City of Hope, scientists like TGen distinguished professor Nicholas Schork, Ph.D., are working to unlock the secrets to not just better ‘aging,’ but disease prevention alongside longevity, and are making promising progress toward medications and methods that will be tailored to each specific person, rather than those that promise longer healthier lives for all. In this episode of TGen Talks, our host Karie Dozer sits down with Schork to discuss the groundbreaking search for substances that can slow down aging. Imagine a daily pill that not only extends your lifespan but also your health span, delaying age-related diseases like heart disease, diabetes, and cancer. Schork, with his extensive background in quantitative genetics and translational biomedical science, explains the exciting potential of longevity and health promoting interventions, termed ‘geroprotectors,’ and the race to develop them. We'll explore the challenges and excitement of developing anti-aging interventions, the race to find effective solutions, and the potential of personalized treatments through “N-of-1” trials. Join us as we delve into the future of aging research and the hope it brings for healthier, longer lives.…

On this month’s TGen Talks, David Engelthaler, Ph.D., professor and director of TGen’s Pathogen and Microbiome Division, discusses the recent surge of bird flu, also known as H5N1. H5N1 has been in the news a lot lately, but what does it all mean? Engelthaler breaks down the science and talks about the effects this particular strain might have on humans. He also explains what constitutes an outbreak, how they fade over time, and why they start anew. Bird flu, like other influenza viruses, changes and mutates over time, and the H5N1 strain is particularly concerning. Although it is currently a low risk for human outbreak (there are only 3 known cases in the U.S. thus far), its impact on other animals, especially poultry and cattle, caught the attention of the CDC, USDA and other groups that monitor such outbreaks. Engelthaler notes that outbreaks are often first noticed by wildlife managers or at zoos, where bird die-offs prompt testing for influenza. Over the past two years, the current bird flu strain has spread significantly by wild birds across North America and the rest of the world. The good news: In Arizona, only one mammal, an Abert’s tree squirrel, has tested positive for H5N1 to date. TGen researchers are working with local wildlife and health officials to monitor the situation.…

This month, TGen Talks explores polygenic risk scores with Dr. David Duggan, an associate professor in the Quantitative Medicine and Systems Biology Division at TGen. A polygenic risk score is a number that indicates the combined effect of many genetic variants on a person's risk of developing a certain trait or disease. Each genetic variant adds a small amount to the overall risk. When these small effects are added together, they help predict the likelihood of developing the trait or disease. Think of the human genome as a deck of cards, where each card represents a different genetic variant. The value of each card represents the risk contribution of that variant. For example, an Ace might represent a high-risk variant (4 points), while a 2 might represent a low-risk variant (1 point). Let's assume all contributions are positive for simplicity, although in reality, some variants might reduce risk. Imagine drawing 10 cards from the deck randomly. These 10 cards represent the genetic variants you inherited from your parents. Each card has a point value (risk contribution). Adding up the points of the 10 cards gives you your polygenic risk score. This score indicates your genetic predisposition to the trait or disease. You can then compare this score against population averages or thresholds to determine if you are at higher or lower risk for the trait or disease. In this analogy, each card represents a genetic variant, and its point value represents its contribution to your overall genetic risk for a specific trait or disease. The polygenic risk score is the sum of these contributions, much like summing the values of drawn cards to get a total score. This information can help you and your doctor make informed health decisions, such as focusing on preventive measures. Dr. Duggan notes that lifestyle factors also play a significant role in disease risk, sometimes reducing genetic risk by up to 50%. Whether you’re a healthcare professional, a genetics enthusiast, or just curious about the future of personalized medicine, this month’s TGen Talks is worth the listen.…

Glioblastoma. It’s the most aggressive and least treatable type of brain cancer. Research into treatment has been slow, mostly because of the difficulty in accessing and treating a tumor that exists behind the blood-brain barrier. A new two year fellowship into Glioblastoma Multiforme, or GBM, aims to better drug therapies to fight the cancer while developing better tests to determine which drugs are working on an individual patient's tumor and which are not. The fellowship, established by Shawn Lane and the Lori Lane Foundation together with Chris and Florence Spyrow, honors Lori Lane and Andrew Spyrow, whose lives were cut short by GBM. This month on TGen Talks, Valerie De Luca, Ph.D., the inaugural Lori Lane/Andrew Spyrow Fellow at TGen discusses her work toward improving our understanding of molecular markers associated with tumor vulnerability to specific drugs.…

Alzheimer’s disease affects an estimated six million Americans. Diagnosing and treating the disease is challenging, and for families taking care of a loved one with Alzheimer’s, it’s even more difficult. Detecting and addressing the disease early on is crucial due to its progressive nature. However, Alzheimer’s symptoms can resemble those of other non-progressive conditions. In a recent Cells publication, a team of scientists describe using machine learning models to identify changes in RNA molecules of plasma extracellular vesicles (EVs) that may hold potential for identifying Alzheimer’s disease (AD) at its earliest stages. This is one of the first studies to show changes in the RNA molecules of plasma EVs that precede neurodegeneration and provides evidence that some of the hidden pathology taking place early in the disease is reflected in plasma EVs, where it can be accessed in a minimally invasive manner and used for biomarker development. On this edition of TGen Talks, study co-author and TGen Neurogenomics Division staff scientist Joanna Palade, Ph.D., discusses their findings, and how what sound like magic or a fortune teller's promise, is the goal of the scientists working to develop a simple test; one that wouldn't simply indicate whether your symptoms might progress to an Alzheimer's diagnosis, but could also estimate the timeframe for when it might occur.…

Paul J. Luna, president and CEO of Helios Education Foundation, sits down with TGen Talks to discuss the transformational power of education, in particular, how internships help prepare students for future success. Helios Education Foundation supports postsecondary attainment for all students, especially low-income and underrepresented communities, in Arizona and Florida. Earlier this month, Helios committed funding to extend the TGen Bioscience Leadership Academy (TBLA) through 2028 (see related story). TBLA spun out of TGen’s Helios Scholars Program in 2018, with a focus on supporting high-school students interested in careers in biomedical research and medicine. In addition to the Helios-funded programs at TGen, Luna discusses Helios’ focus on helping students achieve educational success beyond high school and the importance of opening the programs to all students, regardless of background. And how rewarding it is to help students find a track to success, whatever that success may be. Students should allow themselves to dream big, he says. Be willing to apply, be willing to say, I want to be part of that unique cohort of talented students who are going to learn and evolve and build a network and maybe, one day, find the cure for Alzheimer’s or cancer.…
More than three years after the beginning of the pandemic, humans still spread COVID to one another every day, though with less severe symptoms in most cases. Scientists also know that we can spread COVID to our pets as well, because of the close relationships many of us have with our four-legged friends. While dogs CAN get COVID from humans, they don’t seem to get very SICK. So, what’s the big deal if we spread the virus to our pets? Can dogs spread it back to humans or to other animals? TGen scientists are looking to answer these and other questions in a new study called the 1000 Canine (1K9) SARS-CoV-2 Surveillance Study … and they’re looking for dogs to participate. Hayley Yaglom, MS, MPH, a genomic epidemiologist who leads TGen North’s One Health team and the 1K9 study joins TGen Talks to discuss the study and how the information gained will help tailor guidance for public health, veterinary professionals, and people interacting with dogs in various settings.…
