In this episode of TGen Talks, we explore the art and responsibility of mentorship in biomedical research. Behind every breakthrough is not just data and experiments, but the guidance of seasoned scientists who shape the next generation. And while the results may not appear in a lab notebook, they’re just as important.TGen neuroscientist and educator, Dr. John Fryer, joins the podcast to share how mentorship transforms careers, fosters resilience, and sparks creativity. From the lessons learned in his own training to the values he instills in his lab today, Dr. Fryer reminds us that science is an apprenticeship at heart, and choosing the right mentor can make all the difference in the world.Because in the end, the breakthroughs we celebrate are powered not only by experiments, but by the people who take the time to guide others along the way.
For many Arizona students, the path into science begins with a single summer that reshapes their confidence and their future. Since 2007, the Helios Scholars Program at TGen has been that turning point. Each year, Helios Scholars spend eight weeks working directly with TGen researchers exploring cancer biology, neurological and infectious disease, diabetes, and the fast‑growing world of computational genomics. Some even step into administrative roles that keep scientific projects moving. The program began with a Helios Education Foundation grant in 2006. The pilot’s success led to a $6.5 million endowment and the official launch of Helios Scholars at TGen, a program built to educate, inspire, and strengthen Arizona’s STEM workforce. Now entering its 20th year, the impact is undeniable. Alumni have published research, earned national recognition, and joined top graduate and medical programs across the country. Helios alumna Saahithi Mallapragada joins TGen Talks to discuss how her Helios experience became a launchpad for her career in science. You’ll hear about her internship experience, her work in the lab, and why she would encourage anyone to apply to the Helios Scholar program to see if science might be a true passion.
May is Brain Tumor Awareness Month. In this episode, meet two new TGen researchers whose shared love of science—and math—first brought them together in the lab and later in life. Drs. Simona Migliozzi and Luciano Garofano are married to each other and to their work. They discuss their education in Italy, their research journeys across institutions in the U.S., and the path that ultimately led them to TGen, where Dr. Garofano’s expertise in math and statistics pairs seamlessly with Dr. Migliozzi's passion for improving outcomes for patients with glioblastoma. You’ll also hear about their individual contributions to the growing body of GBM research and learn which partner believes the other is the true “smart one” in the partnership.
It’s well known that smoking is the number one factor that significantly increases your risk of developing cancer over a lifetime. But obesity also poses an increased risk. While the relationship is well known, the reasons behind the link between body weight and cancer were not … until now. In this episode of TGen Talks, Dr. Cristian Tomasetti, senior author on a recent study in Cancer Research, highlights why obesity and cancer are so closely connected. While the link between excess weight and cancer has long been observed, Tomasetti and colleagues are the first to mathematically explain why the risk rises. Their work revealed that obesity enlarges organs, increasing the total number of cells that could potentially become cancerous. This episode blends math and medicine for a compelling look at how understanding cancer at the cellular level can shape the future of risk assessment.
March is Multiple Myeloma Awareness Month. In this episode, we speak with TGen Associate Professor Jonathan Keats, Ph.D.Dr. Keats’ revisits the COMPASS study from the Multiple Myeloma Research Foundationm a 12-year research project that examined the different forms of this blood cancer and revealed why some patients respond well to treatment while others face more aggressive disease. His work on the project led to the development of two advanced tests that can deliver results in days instead of weeks, helping doctors choose the most effective treatment for each patient.These tests can also show when some patient may no longer need therapy, sparing many people from years of difficult and costly treatments. Listen as Dr. Keats shares why he believes the future is becoming much brighter for patients with multiple myeloma and other forms of cancer.
Why do some people stay mentally sharp well into their seventies and eighties, while others begin to struggle with memory much earlier in life? MindCrowd, an ambitious online brain study created at TGen, set out to explore that question more than a decade ago. Instead of bringing small groups of volunteers into a lab, Matt Huentelman, Ph.D., and his team did something almost unheard of at the time: they opened the study to anyone with an internet connection. In just a few minutes, participants answered basic questions and completed simple tasks that measured memory and reaction time. Over time, those millions of data points have revealed how thinking, learning, and remembering evolve across the human lifespan. Today, MindCrowd is nearing an extraordinary milestone: one million participants. That massive, global dataset representing people of all ages, backgrounds, and countries has made possible discoveries that simply couldn’t be captured in traditional studies. Researchers have seen clear patterns in how response time changes with age, consistent performance differences between men and women, and even surprising findings about participants with high blood pressure. And despite our widespread fears about Alzheimer’s and dementia, MindCrowd reinforces a hopeful truth: roughly 87 percent of us will not experience dementia in our lifetime. As the project approaches the one-million mark, Dr. Huentelman joins us to talk about what study’s already taught us, the outliers who intrigue him most, why identifying the factors that protect, or challenge, our brain health matters to every one of us, and how this work moves us closer to the goal of precision aging.
Episode 87 of TGen Talks features Dr. Haiyong Han, who dives into his latest work on one of the deadliest of cancers: pancreatic cancer. He breaks down why this disease is so hard to catch early, how it can grow silently for years before symptoms appear, and why identifying true positives in the general population is such a big challenge. Dr. Han also shares promising progress toward a new non-invasive screening test that could one day enable earlier detection of pancreatic cancer. The goal? To turn this deadly disease into a more manageable condition, and give patients real hope for the future.As we recognize Pancreatic Cancer Awareness Month in November, this episode emphasizes the urgent need for improved diagnostic methods, more effective treatments, and continued research to change the outcome for patients everywhere.
In this episode of TGen Talks, we sit down with three researchers who are working to make cancer care safer and more precise for some of the most vulnerable patients—children with rare brain tumors.Dr. Floris Barthel, Dr. Shea Gallus, and graduate student Sharvari Mankame are part of a team at TGen and Phoenix Children’s Hospital exploring liquid biopsies—a method that uses small samples of blood or spinal fluid to detect and monitor brain cancer. This approach could reduce the need for invasive surgeries, which are especially hard on young patients.Our guests explain how liquid biopsies work, what they’re learning from genetic markers called K-mers, and how artificial intelligence is helping them analyze tumor DNA in ways that weren’t possible before. Their goal is to find a better way to track cancer in real time—giving doctors more information while easing the burden on patients and families.While this science is still developing, it’s already showing real potential to shift how we approach diagnosis and treatment—not just in pediatrics, but across cancer care.
What connects a fashion show to biomedical research? More than you'd expect—especially in the fight against women’s cancers and the local support for TGen and City of Hope. TGen’s 5th annual Runway for Research takes place on Friday, October 17, in partnership with Neiman Marcus, Scottsdale Fashion Square, and City of Hope Phoenix. Runway for Research blends fashion and purpose, supporting advancements in women’s cancer research and treatment. Attendees will experience the season’s latest runway trends, connect with community leaders, and support groundbreaking local research. In this episode of TGen Talks, Runway co-chairs Lee Courtney and Amy Hair spotlight Runway for Research, and explain why it’s about more than style; it’s about saving lives. This year’s “Pink Elegance” theme continues the color tradition launched in 2023, encouraging guests to wear their favorite shades of pink in honor of cancer survivors and in support of future discoveries. Registration is now open at tgen.org/runway.
What if medicine worked to get you healthier overall—not just people like you or for one or another symptom? In the latest episode of TGen Talks, host Karie Dozer sits down with Nicholas Schork, Ph.D., and Laura Goetz, M.D., co-authors of a recent commentary published in Nature Communications, From Precision Interventions to Precision Health, to explore the promise—and complexity—of truly personalized healthcare. Traditional medicine treats symptoms. Precision healthcare, however, rethinks that model entirely. By tapping into genomics, environment, lifestyle, and even real-time data from wearable devices, Drs. Schork and Goetz discuss developing highly individualized approaches that don’t just treat illness—they aim to prevent it. Together, they unpack how this shift could redefine everything from how drugs are tested, to how diseases are managed, and even how we define “health.” They discuss cutting-edge innovations like anti-sense oligonucleotides—drugs custom-made for an individual’s genetic code—and the rise of geroprotectors, compounds designed to support whole-body wellness as we age. They discuss the difficulties of such specific treatments and the differences in the way different patients might metabolize and respond to the same medicine. The future of medicine isn’t one-size-fits-all. It’s N-of-1—and it might just be closer than you think.

On this month’s TGen Talks, our host sits down with Leigh Nicholson, Ph.D., who was recently named a research assistant professor in TGen’s Early Detection and Prevention Division. Nicholson studies neurological diseases of all kinds — from the rarest to the very common — including a childhood disorder called Okur-Chung neurodevelopmental syndrome, or OCNDS for short, and Alzheimer’s disease, which affects nearly 7 million Americans. The podcast covers her path to a career in science, her day-to-day research, and why she thinks mentoring young scientists and improving scientific literacy is so important. All this and more, in just under 15 minutes.
Every September, the scientific community recognizes postdoctoral researchers during Postdoc Appreciation Week. Postdocs bring new ideas and deep expertise as they tackle complex questions and expand knowledge through experiments. In this month’s episode of TGen Talks, Aya Kamzina, Ph.D., one of TGen’s 11 postdoctoral researchers, shares her journey to becoming a postdoc and her experiences at TGen. Dr. Kamzina’s educational path began in Kazakhstan and differs from many of her peers. She discusses her work with organoids and microglia in Dr. Huentelman’s neurogenomics lab, as well as her diverse background in biochemical engineering and molecular biology. Dr. Kamzina also explains why she finds TGen’s translational research meaningful and how it aligns with her goals in shaping the future of science.
Scientists at TGen have released the results of a more than decade-long study into multiple myeloma. Looking at more than 1100 patients from four different countries, scientists identified new genetic subtypes of the disease, providing insights that could transform how we approach treatment (see related story above).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.
In this episode of TGen Talks, we explore the overlooked yet vital world of skin cancer prevention and treatment. Our skin, the body's largest organ, often takes a back seat in discussions about cancer. Join us as we delve into this crucial topic with our guest, Dr. Aleksandar Sekulic. Dr. Sekulic wears two hats: that of a clinician and a researcher. He shares how his interactions with patients inform his research, leading to groundbreaking advancements in skin cancer treatment. From pioneering clinical trials to developing targeted therapies and immunotherapies, Dr. Sekulic sheds light on the complexities of skin cancer and the importance of bridging the gap between medicine and research. Discover the different types of skin cancer, from melanoma to basal cell carcinoma, we’ll explore the various facets of this disease, its impact, and the latest advancements transforming the landscape of skin cancer care. Learn about the challenges posed by complex skin cancers, such as locally advanced and metastatic basal cell carcinoma, and the innovative treatments being developed to address them. Tune in to gain a deeper understanding of this often-underestimated aspect of healthcare as our host, Karie Dozer, works to uncover the latest insights and advancements in skin cancer research and treatment with Dr. Aleksandar Sekulic.
Cancer continues to be the second most common cause of death in the United States, with a total of nearly 2 million diagnoses every year. In this episode of TGen Talks, recorded in front of a live studio audience, we take a look at how genomic information is leading to better and earlier diagnoses and treatments for all kinds of cancer and how the collaboration between City of Hope Cancer Center Phoenix and TGen is proving to be a mighty weapon in the fight against cancer right here in Arizona. Joining the podcast this month are TGen President and Research Director, Dr. Jeffrey Trent, and City of Hope Cancer Center Phoenix Chief Clinical Officer, Dr. Alan Bryce.
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.
Today, the world of biomedical science is changing how we think about disease and, certainly, how we treat it ... but did you ever wonder how discovery happens? What does a lab look like? What type of equipment do they use? Who exactly is working inside? How many scientists and staff? And on what projects? On this episode of TGen Talks, Kristen Kaus, Manager of TGen's Education and Outreach programs, talks TGen, specifically, what guests and visitors see and hear when they go on a tour. While you might not learn everything modern research, you will gain an insider’s knowledge of TGen. She also talks about STEM education and the programs at TGen designed to foster a love of science and support students aiming for a career in bioscience. If that’s you, a TGen tour is a great way to see science in action.
For a patient diagnosed with multiple myeloma, a type of blood cancer, there are more treatment options than ever and traditional chemotherapies that cause debilitating side effects have been all but completely replaced by immunotherapies, treatments that help a patient's own immune system better fight the disease. But in many patients, a chosen immunotherapy drug can show great promise in early treatments, yet seemingly stop working altogether as time goes by. In a paper that was published in Nature Medicine, TGen's Dr. Jonathan Keats explains how upwards of 65% of relapsing multiple myeloma patients could be affected by mutations that impact targeted T cell treatments. On this episode, you'll hear about a study that found how these cancer cells were mutating to evade the very drugs prescribed to fight them. The findings could help clinicians and patients choose from among a variety of T cell therapies for multiple myeloma to find treatments that best match a patient’s available tumor targets. Dr. Keats also discusses his broader work in multiple myeloma and plans for a rapid sequencing center that will place valuable genomic-informed data in the hands of treating physicians in just 48 hours. All this and more on TGen Talks.
The phrase "gut health" has become quite a buzzword in recent years, and researchers like this month's guest will tell you quite candidly that we have a lot to learn about the community of microorganisms that live INSIDE the human body. But one thing seems to be clear. The human being with a "healthy gut" is far better able to fight a cancer diagnosis than the human with poor gut health. Regardless the current standard for a healthy human microbiome, the data being compiled on this relatively new topic is vast. One TGen researcher is uniquely qualified to analyze and manage such data, and is doing so at TGen North. Dr. Greg Caporaso is a bioinformatician-- with expertise in both computer science and the human microbiome. On this episode of TGen talks, he explains how his study of this important body system started not in a pre-med class, but in the computer lab.
Most of us had a summer job when we were in high school or college, and if we were lucky, we had one that helped us make meaningful decisions about college or a career.
At TGen, summer interns in the Helios Scholars at TGen program work alongside researchers on projects that are much more than “just” eight weeks of full-time hours inside a lab. Many Scholars choose a field of research they will pursue for an entire career.
On this episode of the TGen Talks, we connect with Heather Mead, Ph.D., a research assistant professor in TGen’s Pathogen and Microbiome Division. A former Helios Scholar who describes the eight-week internship as life changing and encouraged her to begin a second career in research, one that has seen her come full circle as today she mentors Helios Scholars, helping them find and follow their passion … all while conducting research and coordinating projects around Tuberculosis, Valley Fever, COVID and more.
What if you could take a simple test to find out just how susceptible you are to Covid19, the Flu, or any other virus? What if you could test your exposure and immunity to EVERY virus known to mankind using a single drop of blood? The technology is here, now. And at TGen, researchers are using it to understand the human immune response and predict and track the next global outbreak. What's more, the human immune system not only protects us from viruses and pathogens, it can help prevent the onset of deadly diseases triggered by those infections. This month's podcast is an introduction to something called PepSeq (pep-seek), a breakthrough technology that allows scientists at TGen to detect infections by – and immunity to – the entire human virome.
This month, our host Karie Dozer sits down for a personal conversation with Maria Fundora, who is neither a scientist nor a clinician. She's a businesswoman from Alpharetta, Georgia, a restauranteur and founder of Purple Pansies, a nonprofit organization dedicated to raising awareness and funds for pancreatic cancer research. And like most nonprofits that support research, there's a story about how it all began, and most often in whose memory. Maria's mother passed away from pancreatic cancer in 2007, inspiring Maria to start Purple Pansies. The organization began with $3,500 raised on Mother's Day in 2008. Maria chose the name Purple Pansies because purple represents pancreatic cancer and pansies symbolize resilience. Initially, Purple Pansies held two annual events, a community gathering and a gala in Maria's restaurant. It wasn't until 2010 that Maria learned about TGen. Impressed by TGen's approach, Maria established a partnership that to date has raised millions. All this and more with Maria Fundora on TGen Talks.
Understanding how infectious diseases spread in the past is important to understanding how they affect populations today. The difficulty lie in piecing together information given that so little is known about how microbes spread historically. Applying academic rigor with scientific assessment, two microbiologists teamed with an archaeologist to look at different types of evidence — genetics, anthropology, paleontology and climate — in an attempt to explain how the fungus that causes Valley fever, Coccidioides immitis, ended up in a specific area of Washington state. The review article in mBio by Drs. David Engelthaler, James C. Chatters and Arturo Casadevall details their approach from a historical perspective, applying what they knew about the biology and epidemiology of C. immitis, which led them to propose a new theory for why it has emerged in that region of Washington. Today, a great deal of discussion around the spread of diseases and the expansion of their habitats focuses on the effects of global warming. And while climate change does have an impact on different environments and habitats, this investigation sought to understand how and why different microbes, like fungi, move from one place to another through the lens of modern biology. Their final analysis, climate change may not always be the reason behind the spread of diseases, but it can reveal past events that could be dangerous. Engelthaler explains more in this edition of TGen Talks.
When treating cancer patients, physicians are often faced with tough choices. Treatment options like radiation can often come with unpleasant, for some, unbearable side-effects. Doctors walk a fine line between stopping the growth of cancer cells and giving cancer cells the very thing they need to grow and spread. City of Hope and TGen physician-scientist Yun Rose Li, M.D., Ph.D., has been called trailblazing and innovative by the NIH in her research into oxidative stress and its effects on cancer cells. Dr. Li is using a five year, nearly $2 million grant to study how manipulating oxidative stress can improve the outcomes of her patients with genitourinary cancers. Recruited for her research while still a resident at UC San Francisco, Dr. Li is quickly proving it no longer takes a lifetime in cancer research to make a difference in the lives of patients.
In part two of TGen Talks Live, we continue our conversation on precision aging with Drs. Matthew Huentelman and Nicholas Schork.Aging encompasses a variety aspects—both physical and mental—a fact made evident by the topics covered and the research presented. Where Huentelman’s work covers the brain and the more cognitive aspects of aging, Schork’s work focuses on the physical changes we undergo as we age. This month, in part two of our live show, our guests talk about how the COVID pandemic affected our bodies and brains, and how we can best separate fact from fiction when it comes to anti-aging supplements.
TGen offers listeners a deeper dive into a particular biomedical-related topic or program through its monthly podcast TGen Talks.

Humans have been searching for the fountain of youth (a mythical endless supply of waters that purport to keep us young forever) for thousands of years—but there’s no such thing in the world of science. At TGen, scientists are working toward a virtual fountain of youth, and they call it precision aging. On this month’s TGen Talks, Matthew Huentelman, Ph.D., helps us understand precision aging a bit more clearly, as he explains the concepts behind the process, and discusses just a few of the benefits it may hold for our future. This month’s podcast also tees up a first-ever TGen Talks Live event slated for December, where Huentelman and his colleague, Nicholas Schork, Ph.D., join our host Karie Dozer for a deeper dive into precision aging, and how genomics may hold the answers for a longer and healthier life
Cancer is the number one worry of pet parents, and it's no wonder. More than half of all dogs older than 10 will be diagnosed with cancer. Cancer is hard to treat in many dogs, and is often diagnosed when it's too late to treat. Americans spent more than $120 billion on their pets just last year. One TGen subsidiary is putting its science to work for pet parents, so that cancer in dogs is diagnosed before it's too late. Vidium Animal Health is a wholly owned subsidiary of TGen and it works to diagnose and treat canine cancers.
With COVID infections and deaths on the decline worldwide, many researchers are turning their attention back to a familiar foe. Tuberculosis (TB) was the number one infectious disease killer before the emergence of COVID-19, and it is number one again today. Although most Americans are not at risk of contracting TB, it continues to be a danger worldwide. TGen researchers are trying to find better diagnostics for this very stubborn bacterial infection, and combat antibiotic resistance so that doctors everywhere can better treat this ancient illness. TGen North research scientist Megan Folkerts joins TGen Talks to discuss TB’s history, Egyptian mummies, TGen North's efforts to design better diagnostics, learning how antibiotic resistance stunts treatment, and improved ways to overcome its effects on new or current therapies. All this and more on TGen Talks.
For Crystal Hepp, PhD, the newest member of the TGen North team, understanding how different pathogens move over time and space and through different populations is all in a day’s work. Recently, that work has centered heavily on RNA viruses, and given that the translational aspects of her work aligned seamlessly with the TGen North team and its mission, the decision to join the team came fairly easy. Spread through the bite of the common house mosquito, West Nile virus is the leading cause of mosquito-borne disease in the United States. Hepp discusses her work with county vector control agencies throughout the southwest to collect and test mosquitoes, work that helps identify locations that are viral hot zones. Additionally, Dr. Hepp discusses a unique method for collecting local wastewater samples across wastewater treatment plants, local school districts, and university residence halls testing for COVID —a partnership between the City of Flagstaff, Coconino County Health Services, Northern Arizona University, and TGen— and plans for a study to look for coronaviruses in different animal populations to understand which populations might be able to be reservoir species, then estimate when or if spillover back into humans could occur. All this and more on TGen Talks.
This episode of TGen Talks takes the listener along I-17 from Phoenix to Flagstaff, where our host, Karie Dozer, sits down with David Engelthaler, Ph.D., professor and director of TGen’s Pathogen and Microbiome Division, more commonly known as TGen North. Whereas TGen uses genomics to solve complex problems such as cancer and Alzheimer's disease, the scientists at TGen North use these same tools and technology to focus on infectious disease … the microbes, the bacteria, the viruses, the fungi that cause some of the greatest problems around the world. Engelthaler provides the listener an inside look at the research underway across the division, and the community work with different tribal nations and hospitals to understand what’s most important to them and how TGen North can apply their expertise to support those needs. Whether it's Cryptococcus, tuberculosis, superbugs in our hospitals, or other bad things like plague, West Nile, Valley fever, COVID, or the latest efforts around pathogen intelligence, TGen North’s goal is and always has been to rapidly identify and help stop the spread of potentially dangerous outbreaks. All this and more, on TGen Talks.
Dr. Johanna DiStefano joins TGen Talks to discuss nonalcoholic fatty liver disease, or NAFLD, a condition that causes excess amount of fat in one’s liver cells. As evidenced by its name (which could use an update, according to our guest) NAFLD covers a wide-range of liver conditions with the “alcohol” portion somewhat misleading, as it’s not always that cut and dry. Different factors, such as genetics, lifestyle, and diet could also play a role in NAFLD. It could also be one’s gender or one’s stage in life. For example, the risk increases for women following menopause. Dr. DiStefano discusses her labs focus on the genetic factors that influence the development of NAFLD and increasing awareness of this population among clinicians. How does nonalcoholic fatty liver disease develop? How does the liver communicate with other cells in the body, other organs in the body? The long-term goal, of course, is identifying better ways to detect and treat fatty liver disease. And that means new tests and new drugs. All this and more on TGen Talks.
This year marks the 20th anniversary of TGen's founding on what at the time was a relatively unknown idea outside the circles of academia and scientific research, precision medicine. The concept of using a person's own genome to diagnose and treat disease at an individual level, to move beyond the one-size-fits-all treatment plans that had dominated the medical landscape for decades, where drugs and therapies considered large groups of people with the same disease, and what worked for the majority.
A true public-private partnership, TGen came to fruition through the work of tribal leaders, CEOs, philanthropic trusts, foundations, individuals and university presidents, all united toward an extraordinarily high-risk goal: Forming and funding an institute based on the just-completed Human Genome Project and placing it not in Boston, San Francisco or Washington, D.C., but in Phenix, Arizona.
TGen founder, Dr. Jeffrey Trent, joins TGen Talks to discuss the institute’s beginnings as well as how over the past 20 years, TGen faculty have leveraged the human blueprint to advance the diagnosis and treatment of various cancers, neurologic and metabolic diseases such as Alzheimer’s, diabetes, and rare disorders.
Applied mathematics dramatically advanced the field of finance in the 1970’s, where its application allowed for the modeling of financial markets by mathematicians highly skilled in quantitative analytics. Today, these highly sought-after mathematicians are making a name for themselves in the field of applied science as their skills are increasingly providing solutions in many areas of biomedical research. The genomic sequencing routinely employed by TGen in precision medicine platforms generates data on a massive scale. Applying mathematical modeling, statistical methods, and machine learning, to these complex datasets has the potential to transform longitudinal (i.e., the same patient sampled over time) genomics data into new predictive biomarkers of disease or response to treatment. In the latest edition of TGen Talks, Dr. Cristian Tomasetti discusses his mathematical grounding, how applied mathematics influences modern biology, his work at TGen and City of Hope, and the role of somatic mutations on cancer. All this and more in under 20 minutes.
TGen’s Scientific Technology Assessment Research Team (START) supports the research faculty by bringing new technology into the labs to help answer today’s most pressing research questions. When the current tools for measuring DNA or proteins or cellular structure aren't sufficient, START scouts the technology landscape for companies that are developing new methods that can, often by partnering to beta test the technology. And that means TGen gains early access … but only after the START lab vets the technology through rigorous testing at a biological level. Stephanie Pond, Ph.D., Vice President of Emerging Technologies and head of TGen's START program, joins TGen Talks to discuss START. She explains how technologies make the cut, and the avenues by which new technologies hit the START radar. She also discusses a recent collaboration between TGen and Bay Area start-up, Deepcell (see related story Going Deep), who developed a system focused on cell imaging and cell sorting that allows researchers to predict how cells will function based on how they look.
For our final episode of TGen Talks in 2021, our host, Karie Dozer, sat down with TGen North Director, Dr. David Engelthaler, who has led TGen’s research into COVID since day one. Dr. Engelthaler shares his thoughts on Omicron … what we know, what’s left to learn, and why it’s spreading so fast. While it may be a bit early to predict how Omicron will play out in the U.S., it appears to follow trends seen with other variants and is on pace to replace Delta as the most dominant variant, which may not be all bad news, particularly if it produces symptoms that are milder than its predecessors. Dr. Engelthaler also discusses which states seem to be hit the hardest, how that changes week-by-week, immunity against Omicron for the fully vaccinated, and how a strong cellular immunity helps prevent serious illness. All this and more in just eighteen minutes on TGen Talks.
Genomic analysis of a cancer tumor is fairly common these days. Researchers sequence and compare a patient’s non-cancerous DNA with their tumor DNA to identify changes that may allow a patient to receive medicine that specifically targets those changes. But what happens when the tumor comes back? Has the tumor changed? And if so, how? These were questions that intrigued TGen Assistant Professor Floris Barthel, M.D. In particular, his latest research focuses on the effects of radiotherapy on the cancer tumor. What is different in the DNA of the first tumor compared to the normal DNA, and what is different in the DNA of the second tumor compared to the first tumor? How does treatment affect the DNA of these tumors over time? On this episode of TGen Talks, Dr. Barthel discusses how his work has shown that radiotherapy, while highly beneficial, appears to create breaks in the DNA and instead of dying, the cancer cell repairs itself, which alters the tumor make-up upon recurrence. He cautions there is still much to discover, but if successful, it could help identify those relapsed patients resistant to further radiotherapy and allow treating physicians to suggest an alternate course of treatment.
At the Center for Rare Childhood Disorders, it's all about the kids. Center staff dedicate themselves to finding a diagnosis and possible treatments for disorders so rare that many may not even have a name. In episode 42 of TGen Talks, we go inside the Center with Clinical Director Keri Ramsey, who talks about the parents and kids who come to the Center for answers, and how TGen scientists are solving as many of these medical mysteries as possible ... some years after the search began through a special program that brings cold cases to the forefront and offers renewed hope to families in search of answers.
For TGen’s Dr. Matt Huentelman, leveraging today’s technology to rewrite the playbook on research recruiting and reimagine the scientific landscape involves attracting people to genomic studies in a whole new way. Leaning on a riff from the Doobie Brothers, Huentelman wants to take it to the streets. The Internet — in one form or another — has been around since the late 1960s, yet it’s only been within the last decade or so that scientists have taken advantage of online platforms to recruit for and drive large-scale research studies. For Huentelman, his MindCrowd study was among the early adopters and today has recruited over 160 thousand participants. But, not wanting to stop there, he believes the next iteration involves mobile laboratories that bring the science to a town and neighborhood near you. This month, on TGen Talks, Dr. Huentelman addresses his latest efforts with MindCrowd, plus his drive to understand aging and age-related diseases through a process he refers to as precision aging. And not just for some. Studying diverse populations remains critical to fully understanding aging and how it effects all walks of life and all aspects of society — from urban to rural and everywhere in-between. Is a mobile lab visit in your future?
The range of emotions a Helios Scholar at TGen experiences — from application through the program’s end — shifts dramatically as the summer unfolds. The end result, however, is one of accomplishment. 2021 marked the 15th year of TGen’s flagship internship program that has seen nearly 600 alumni gain often career-defining exposure to biomedical research and medicine by working alongside TGen faculty and staff. In episode 40, TGen Talks host Karie Dozer sits down with three Helios Scholars from the class of 2021 who share their summer of science as they discuss what they've learned and how they'll put that training to use as they move forward in their careers.

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.
With the Delta variant of COVID-19 garnering worldwide attention, it begs the question: When will the pandemic end? This month, on Episode 38, we circle back with David Englethaler, Ph.D., Director of TGen's Pathogen and Microbiome Division, more commonly known as TGen North, for an update on all things COVID-19 related. How much longer will we be dealing with COVID-19? Do we really know where COVID came from? Will we need vaccinations against COVID for years to come? Dr. Engelthaler answers these questions, and also explains how TGen is working with local and state health officials to track variants of COVID-19 — and posting that information freely on Arizona COVID-19 Sequencing Dashboard— and how we’re preparing for the next pandemic.
Hearing the words you have cancer comes as a shock. Hearing that your child has cancer is almost unimaginable. And when you learn that it is a rare form of brainstem cancer known as diffuse intrinsic pontine glioma or DIPG — a central nervous system cancer that forms from glial cells, the supportive tissue of the brain and spinal cord that affects less than 300 children per year — the questions become endless. Joining TGen Talks is Dr. Michael Berens, professor and director of TGen’s Cancer and Cell Biology Division and head of the Glioma Research Laboratory, whose research efforts focus on conducting genomic profiling of tumors to increase the understanding of DIPG at the genomic level and developing techniques to monitor how tumors are responding to treatment. Brain tumors are now the most common cause of cancer related death in children younger than 15 years of age today, with DIPG accounting for nearly 80 percent of all brain stem cancer cases. Dr. Berens talks about liquid biopsies and the efforts to rewire a misbehaving gene and what influence it could have on regaining control in the body’s cells. He also talks about the real hope in terms of pushing on the boundaries of the disease and explains his mantra “most best days.” It’s worth a listen.
At TGen, scientists have studied naturally occurring cancer in canines for over a decade. This expertise led to the formation of a company aimed specifically at partnering with veterinarians to identify treatment options for our four-legged friends and bring greater peace of mind to pet parents. Vidium Animal Health was launched in September of 2020, to provide genomic based precision medicine to veterinary oncologist through its flagship test Searchlight DNA. Searchlight DNA was designed to specifically identify any of the nearly 120 known cancer associated genetic mutations in dogs and to use the molecular profile of misbehaving genes to help guide diagnosis and treatment. In episode 36 of TGen Talks, veterinarian and Vidium president Dr. David Haworth discusses how Vidium can help inform veterinarians and pet parents about which mutations are causing their pet’s cancer to grow and spread, and how Vidium wants to use precision medicine to combat canine cancer in new and more effective ways.
At TGen's Center for Rare Childhood Disorders, we are committed to developing, refining, and applying the latest tools of genomic medicine to help diagnose and direct treatment for children with rare diseases and disorders.
Did you know that there are over 7,000 rare diseases that affect over 25 million Americans? Many of these patients endure a diagnostic odyssey that involves multiple tests and doctor visits that all too often are expensive and painful, yet offer no additional clues.
To address this challenge, TGen established the Center for Rare Childhood Disorders in 2012 with the goal of using advanced genomic testing to identify the factors that cause rare disorders in children, which comprise approximately half of all rare disease patients.
In honor of Rare Disease Day (February 28) Center medical director, Vinodh Naryanan, M.D., talks numbers, treatments and more on this month's edition of TGen Talks.
It took under a year to develop, test and begin to deploy vaccines against COVID-19. And despite a few hiccups upon arrival, the rollout is underway... and that's great news for a world that's nearing 100 million cases and over 2 million deaths. Joining TGen Talks to discuss his take on COVID-19 vaccines is Dr. David Engelthaler, Director of TGen North, the Pathogen and Microbiome Division of TGen located in Flagstaff, Arizona. Dr. Engelthaler discusses the vaccine's available today, those that are currently in the development pipeline and why getting vaccinated is important. He also tackles the known side-effects, the speed at which the vaccines were developed, and the recent variant strains that were discovered in the UK, South Africa and elsewhere, and which of these are already being seen in the US. All that and more on this month's edition of TGen Talks.
Internships provide students an opportunity to learn more about potential career choices and equally important, following the experience, gauge whether that career is right for them. Joining TGen Talks is Josh Niska, MD — a 2007 Helios Scholar at TGen — who explains the value of his Helios internship experience, how it helped shape his career, and how the lessons learned at the bench continue to inform his work as a radiation oncologist. He explains how the technologies and techniques and concepts he learned at TGen helped with his undergraduate education, medical school, residency and his work today. He also discusses the importance of mentorships, and how the Helios Scholars at TGen program offered more than just applicable hands-on learning but created friendships and networks that exist to this day.
For 45 students, Summer 2021 could be life-changing … an opportunity to look into the future of biomedical science and see where their own careers could lead them. It’s possible thanks to The Helios Education Foundation and TGen. For 14 years, these forward-thinking organizations have offered gifted students the opportunity to work on real-life projects as paid interns, side-by-side with skilled TGen mentors. In this podcast, learn how this program has been a springboard to inspiring careers and find out how the next generation of students can apply to change their lives.
Recent events and social protests have prompted increased dialog, and rightly so, on the topic of diversity, equity, and inclusion in America. It's a big topic that covers multiple segments of society. But this edition of TGen Talks will focus on how diversity relates to the fields of science and medicine. Our guest this month on TGen Talks is Dr. Joseph Mikhael, professor of Applied Cancer Research and drug discovery at TGen and Chief Medical Officer of the International Myeloma Foundation, or IMF, and a counselor on the Executive Committee of the American Society of Hematology, who shares his insights on the into how we all can become better at embracing and understanding differences that make us unique and the value inherent in assessing our own thoughts and beliefs. To Dr. Mikhael, it's not just business, it's personal.
275 days ago, the Wuhan Municipal Health Commission in China reported a cluster of cases of pneumonia … a novel coronavirus was eventually identified and labeled COVID-19. Since that time, over 200,000 Americans have died and over 7.1 million have tested positive for the disease. Globally, the number of deaths has reached 1 million with more than 33 million citizens testing positive. Our guest this month on TGen Talks is Dr. David Engelthaler, co-director of TGen North, the Pathogen and Microbiome Division of TGen located in Flagstaff, Arizona, who shares his insights on the latest information and developments surrounding COVID-19 — locally and globally — from testing to the value of masks, and vaccine development.
Immune cells, also known as white blood cells, help the body fight infection and disease. Now, scientists and clinicians at TGen and City of Hope are using immune cells in combination with chemotherapy drugs to tailor personalized treatments for cancer patients. Specifically, they're using a mathematical formula to predict who might respond best to this type of therapy. This month on TGen Talks, Sunil Sharma, M.D, TGen Deputy Director of Clinical Sciences and Director of the Applied Cancer Research and Drug Discovery Division discusses immunotherapy, this latest advance, and how it could lead to the development of innovative clinical trials in the future.
Following the lifting of social restrictions and individuals returning to work, the medical profession has seen a recent spike in COVID-19 cases. This month on TGen Talks, Tyler Delaughder, D.O., a TGen clinical research coordinator and recent graduate of Midwestern University, shares his interpretations of the medical issues surrounding COVID-19. Dr. Delaughder provides insight on the progress of testing and what we might expect next by looking into the past, identifying human error, understanding the power of Mother Nature, and the body’s own genomic complexities. Is there a way of stopping future viruses from developing or are they inevitable? And how is the progress being made in the labs at TGen and TGen North informing the medical profession during this pandemic. All this and more on TGen Talks.
For nearly 6 months, COVID-19 has raised numerous questions and concerns, as well as having led to global disruption. In addition to testing, TGen was an early adopter in tracking the virus to learn how it mutates and spreads. Joining TGen Talks to discuss what we've learned is Dr. David Engelthaler, co-director of TGen North, the Pathogen and Microbiome Division of TGen located in Flagstaff, Arizona. Dr. Engelthaler discusses what the epidemiology is telling us about COVID-19, and how that plays into decisions states are making on whether to open, and if so, how broadly? He also discusses the global effort toward vaccine development, the possibility of a second wave of COVID-19 in the fall, lessons learned in terms of public health and how we prepare for other viruses in the future.
What can a few drops of blood tell scientists about how one’s immune system reacted to COVID-19? If you’re TGen North’s Dr. John Altin, you hope a lot. In this episode of TGen Talks, Dr. Altin discusses a new study entitled the COVID Immunity Study whereby citizen-scientists diagnosed with, and subsequently recovered from, COVID-19 can contribute a few blood spots that will enable Dr. Altin to investigate the antibody response against the SARS-CoV-2 virus, which causes the COVID 19 disease. Through his study Dr. Altin, an Assistant Professor in TGen’s Pathogen and Microbiome Division, hopes to find antibody signatures of exposure that are clear and robust and perhaps even signature that differentiate the different types of disease that people experience. The Holy Grail would be signatures that indicate what type of immune response provides protection, versus one that may do more harm than good. The answer may lie in their immune response. This study may find the answers.
The COVID-19 coronavirus continues to affect lives on a daily basis. Businesses, churches, schools, and other public facilities are closing. Sporting events and meetings are canceled daily. News reports tell us how hospitals are grappling with limited testing capabilities. There seem to be more questions than answers, and if ever there was a time for answers, it is now. Joining TGen Talks to discuss COVID-19, is Dr. David Engelthaler, co-director of TGen North, the Pathogen and Microbiome Division of TGen located in Flagstaff, Arizona, who discusses the launch of a genomic-based test for COVID-19, and TGen’s collaborative work with the Arizona Department of Health Services to test for and identify pockets of COVID-19 across the state.
Our DNA tells the story of who we are genetically. But when we develop cancer, our tumor DNA tells a different version of that story. At Ashion Analytics, a subsidiary of TGen, a patient's tumor sample undergoes testing in a CLIA-certified laboratory —through its flagship test, GEM ExTra— to understand how the story changed and how Ashion can help treating physicians identify actionable steps to help their patients. In episode 24 of TGen Talks, Dr. Janine LoBello, Medical Director and Pathologist of Ashion Analytics, discusses Ashion's beginnings, how their services benefit medical professionals, and a few interesting facts you may not know about the BReast CAncer, or BRCA, gene. Listen now or learn more at ashion.com.
The human body contains trillions of individual cells, and inside each resides a unique genetic code. Single-cell RNA sequencing enables researchers to study the mechanics of individual cells and identify the processes underlying disease states — valuable information that helps predict disease susceptibility, or resistance, to drug therapies. This is particularly important in the study of cancer, as cells are constantly mutating. Single-cell sequencing allows investigators to observe these patterns of mutations at a micro-level. In episode 23 of TGen Talks, Dr. Sen Peng, a computational scientist with TGen’s Brain Tumor Unit, discusses how data from single-cell sequencing allows Dr. Peng and his colleagues to study — and make inroads against — the deadly brain cancer, glioblastoma.
Dr. Peng also discusses work with colleagues at City of Hope and elsewhere, and his future plans for studying glioblastoma.
Over the past decade, cancer treatment has gone from a one-size-fits-all approach to a targeted and personal approach known widely as Precision Medicine. Among the leaders at TGen pushing the boundaries of this new frontier is Dr. Sunil Sharma, Deputy Director of TGen Clinical Sciences, Professor, and Division Director in the Applied Cancer Research and Drug Discovery division. Dr. Sharma is a well-known cancer investigator, responsible for helping develop some of the world’s most advanced anti-cancer agents. In episode 22 of TGen Talks, Dr. Sharma discusses his work in drug development and patient clinical trials in concert with City of Hope in California, and TGen’s clinical partnership with the HonorHealth Research Institute. Whether in the clinic, or at the bench, his work helps bring precision medicine solutions to patients in need.
Experts aren’t sure why some people accumulate fat in the liver while others do not, but they all agree it’s a serious health issue.
One type, known as nonalcoholic fatty liver disease — or NAFLD — is a collection of liver conditions affecting people who drink little to no alcohol. It’s also the most common form of chronic liver disease and is tied closely to diabetes.
In episode 21 of TGen Talks, Johanna DiStefano, Ph.D., a Professor in TGen’s Quantitative Medicine and Systems Biology Division and Head of its Diabetes and Fibrotic Disease Unit discusses the connections between NAFLD and diabetes, her work to determine the disease trajectory of patients with NAFLD, and what you can do to avoid getting NAFLD.
Don't let the word rare fool you. Roughly 1-in-10 individuals in the world are affected by a rare disease, and our Center for Rare Childhood Disorders is on a mission to find diagnoses and treatments for these individuals and families. In episode 20 of TGen Talks, Center co-director, Keri Ramsey, explains the advances science has made in genetic sequencing and how we've applied it to help our patients through treatments, gene therapy, and FDA drug testing. Listen to learn more about how our Center and its donors are impacting the lives of our community.
The offer of help to a family friend created a serendipitous chain of events that led Dr. Nick Banovich to study Idiopathic Pulmonary Fibrosis (IPF). IPF is a type of lung disease that scars the lungs and as it worsens makes it for the lungs to take in enough oxygen. In episode 19 of TGen Talks, Dr. Banovich explains how the right collaboration and today's technology make it possible to examine individual cells, rather than a mash-up of many cells from a tissue sample, to identify gene expression changes associated with IPF, work that is breathing new life into research surrounding IPF.
TGen North's Dr. David Engelthaler discusses Valley Fever. We learn why Arizona - with nearly 65% of all Valley Fever cases in the U.S.- is the perfect hotbed for research into this debilitating and potentially lethal disease, and how TGen North is tracking this warm-climate invader and adapting today's technology to provide much needed answers to this age-old problem.

Microbes out-number the genes in your DNA by more than 1,000 to 1 and together they make up what is known as your microbiome. TGen’s Dr. Sarah K. Highlander, a research professor in the Pathogen and Microbiome Division at TGen North and director of the Clinical Microbiome Service Center, works to understand the microbiome and how it is helping scientists better understand cancer, diabetes and a host of other conditions, including traveler’s diarrhea.
Dr. Glen Otero, a 20 year veteran of life science industry and an expert in high-performance computing, discusses artificial intelligence, or A.I., and how it addresses the computational needs of the biomedical research community by executing tasks more rapidly and without human error in a fraction of the time. Today, A.I. is used to process complex genomic data sets to accelerate delivery of personalized treatments for cancer and other diseases by turning raw genomic data —such as a human genome sequence— into usable information to predict disease patterns and treatment outcomes.
In medicine, a biomarker is anything used to determine the presence or development of a particular disease or biological state. They can be used to determine if an injury or disease has occurred, or even if a therapy is working. In this episode, Dr. Kendall Van Keuren-Jensen, a Professor in TGen Neurogenomics Division and Co-Director of TGen’s Center for Noninvasive Diagnostics, discusses how her team is working on ways to use biomarkers — in this case the molecular readout of RNA — as a non-invasive method for studying and treating complex diseases, such as those that affect the nervous system.
Nature vs. nurture? How about nature and nature? Dr. Candace Lewis, a postdoctoral fellow in the Huentelman lab at TGen, walks us through a biological regulatory framework known as epigenomics that changes the behavior of our cells due to our life experiences. Dr. Lewis also discusses the resurgence in psychedelic assisted therapy to treat depression and trauma, and her work in Autism.
