Matt shares his professional history with David, including his early interactions with David in Leonard Guarente's lab at the Massachusetts Institute of Technology (MIT) and scientific differences that emerged after Matt and colleagues were unable to reproduce a key result from David's work pertaining to resveratrol. Their discussion touches on some of David's scientific claims about age reversal, the role of institutions such as Harvard University in regulating scientific integrity, the potential for future interventions in healthspan and longevity, and the importance of separating personal feelings from scientific evaluation. David, currently a professor in Harvard Medical School's Department of Genetics at the Paul F. Glenn Center for Biology of Aging Research, is a prominent geroscience researcher whose lab focuses on age-related epigenetic change, cellular reprograming, longevity drug discovery, mitochondrial fitness, reproductive aging, neurodegenerative disease, and the human secretome. He has received awards including the National Institutes of Health Nathan Shock Award, the Merck Prize, and the Australian Medical Research Medal, and was elected to TIME's 2014 “100 Most Influential People in the World" list. David conducted postdoctoral research at MIT and obtained a PhD in Molecular Genetics at the University of New South Wales.

As we age, NAD+ levels naturally decline. Supplements containing NAD+ precursors such as nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN) aim to counteract this decline by providing the body with the building blocks it needs to restore NAD+ levels. Proponents of these supplements suggest that they may support better energy metabolism, improved cognitive function, and even promote longevity. However, while early research is promising, it's important to approach these supplements with caution and consult healthcare professionals to understand their potential benefits and limitations. For this episode, we examined a 2022 study that looked at the effects of NMN supplementation on VO2 max, or the maximum amount of oxygen a person can use during intense exercise, in amateur runners. Matt and Nick review the study, discuss its limitations, and provide their takes on whether NMN actually improves endurance and aerobic capacity during exercise—and thus whether we should take the claims of NMN supplement sellers seriously.

One of these was Cristal Hill. Cristal is an Assistant Professor of Gerontology at the University of Southern California Leonard Davis School of Gerontology, where she runs a lab focused on how dietary protein might affect adipose tissue (body fat) function, metabolic, and endocrine health during aging. Cristal received postdoctoral training at the Pennington Biomedical Research Center of Louisiana State University, a PhD in molecular biology from Southern Illinois University, and a B.S. in Animal Sciences from Tuskegee University. In this episode, Matt and Cristal discuss fibroblast growth factor 21 (FGF21), a hormone produced mainly in the liver that helps regulate metabolism and control how the body uses sugar and fat for energy. They also chat about FGF21's influence on food preferences, role in healthy aging and longevity, potential as an obesity treatment, and more, as well as the broader impact of protein restriction on health- and lifespan as we age. Some definitions: the term "wildtype" refers to the typical form of an organism or gene as it occurs in nature, and represents the standard or normal genetic makeup and phenotype against which mutants or genetically modified organisms are compared. A "knockout" is an organism in which a specific gene has been completely disabled or "knocked out" to study the gene's function by observing the differences between the knockout organism and a wildtype one. Finally, a "transgenic" organism is one that has had a gene or genes introduced into its DNA to give the organism new traits or abilities, such as resistance to diseases, or to study the effects of the introduced gene.

Subscribe to our channel: https://www.youtube.com/@optispan Check out the Bryan Johnson video: https://www.youtube.com/watch?v=bax8to_s07Q Last month, entrepreneur and venture capitalist Bryan Johnson released a Youtube video detailing his trip to Prospera, Honduras to receive follistatin gene therapy from the Minicircle Gene Therapy clinic. Bryan describes Minicircle's gene therapy as "a pioneering technology with the potential to improve muscle and strength, slow the speed of aging, and many more benefits". In this episode, Matt reacts in real time to his first watch of Bryan's video and responds to Nick's questions about various topics that come up along the way. He provides a primer on gene therapy and its potential as a longevity intervention, discusses the clinical evidence for follistatin's effects on humans and model organisms, and goes through several things one might want to consider when deciding whether to partake in a new therapy. He also gives his honest take on "offshore medicine"—medicine performed in countries that lack the regulatory oversight of the United States Food and Drug Administration—and discusses potential mechanisms for safely offering experimental therapies in the United States. Follistatin is a glycoprotein that functions as a potent inhibitor of several members of the TGF-beta superfamily, particularly activin and myostatin. It is involved in various physiological processes, including muscle growth and development, reproduction, and inflammation. By binding to these proteins, follistatin prevents them from interacting with their receptors, thereby regulating their activity.

One of these was Kevin White, physician at longevity-focused clinic Prime Health Associates in Oklahoma City, Oklahoma. Kevin spent two decades in emergency medicine before obtaining fellowship training in integrative and functional medicine, nutrition, and age management. He complete residency training in emergency medicine and trauma at Washington University in St. Louis, and received his M.D. from the University of Oklahoma College of Medicine. Matt describes him as "one of the few longevity docs who actually comes to the science meetings to learn more about the science of aging." Ultimately, the geroscience field is nothing without the medical professionals who bring new discoveries to bedside. So we really enjoyed sitting down with Kevin and hearing his thoughts on interventions such as stem cell therapy as well as his questions about the geroscience field, which prompted a wide-ranging discussion of rapamycin, the hallmarks of aging, body composition, and more.

One of these was Aditi Gurkar, an assistant professor in the University of Pittsburgh's Aging Institute, Division of Geriatric Medicine whose lab focuses on the downstream effects of DNA damage on aging. Prior to setting up her lab at the University of Pittsburgh, Aditi conducted research on the impact of DNA damage on aging at Scripps Research. She also completed postdoctoral training at Massachusetts General Hospital/Harvard Medical School and the Broad Institute of MIT and Harvard, where she focused on the tumor suppressor p53 as well as on autophagy regulation. Aditi received a PhD and a B.S. from the Boston University School of Medicine and Florida International University in Miami respectively. Matt and Aditi spend much of this episode chatting about senescent cells: how Aditi developed a focus on cellular senescence and found its relevance to aging, potential therapeutic benefits of senescent cell clearance, and the much-debated question of how to define a senescent cell. They also discuss the importance of "zooming out" from narrow areas of focus in the geroscience field to find new solutions and of breaking your own models on your way to productive new directions in science.

Rapamycin belongs to a class of drugs called macrolides and has potent immunosuppressive and anti-proliferative effects. The drug has garnered attention for its potential anti-aging properties and has attracted research interest for its ability to extend lifespan and delay age-related diseases in various model organisms, including yeast and mice. As we've mentioned before, we read every comment on our social media and Youtube channels and often learn a lot from your questions and feedback. For this episode, we collected comments you left containing questions about rapamycin. Many of the questions focus on rapamycin dosing, diet and exercise changes while taking rapamycin, and potential side effects. We also appreciated your curiosity about the state of rapamycin research, evidence for benefit in different model organisms, and the nuances of experimental conditions in rapamycin studies. Keep the questions coming!

Our recent episode on the Interventions Testing Program's recent tests on various longevity interventions sparked some interesting debate on X. City of Hope National Medical Center's Alfred E. Mann Family Foundation Chair in Diabetes and Cancer Metabolism Charles Brenner made a remark about the potential negative effects of rapamycin on humans, while Ponce De Leon Health Chief Operating Officer Mike Muldoon plugged the calcium alpha-ketoglutarate supplement Rejuvant (the ITP tests reported no lifespan extension of alpha-ketoglutarate on mice). Matt responded to these comments on X and some interesting back and forth with Charles and Mike ensued. In this episode, Matt and Nick take a magnifying glass to Charles' and Mike's feedback and examine the published data—and some unpublished data—to consider and respond to their claims. They also discuss the allure of phrases such as "scientifically proven" and "clinically proven" in marketing, and the importance of approaching such phrases with a critical mindset and an eye towards study robustness and methodology as well as the researchers' impartiality.
