Naked mole rat gene, whale DNA repair and mouse lifespan: a video description

What is aging? Why is it the single biggest predictor of disease? And which of the most talked-about anti-aging interventions — telomere extension, biological age tests, supplements — actually hold up? In this conversation we talk to Dr. Vera Gorbunova and Dr. Andrei Seluanov who run a research lab together at the University of Rochester where they study the biology of aging across dozens of long-lived species — from naked mole rats to bowhead whales. A naked mole rat is roughly the size of a mouse but can live past 40 years — more than ten times a mouse's lifespan — and almost never develops tumors. Gorbunova and Seluanov's lab traced that resistance to a single molecule, and when they engineered mice to produce it, those mice developed about 50% fewer tumors and lived 10–15% longer. The same lab has also found a seaweed compound that extended mouse lifespan by 15%, studies a 200-year-old whale that carries 100 times more of a specific DNA-repair protein than humans do, and recently found that controlling a stretch of the genome once dismissed as "junk" nearly doubled the reproductive lifespan of mice. In this episode you'll learn: • What aging actually is, and why it happens in the first place - Why naked mole rats almost never get cancer — and the clogged lab-vacuum tube that led to the discovery • Why a naked mole rat gene cut tumors in half in mice and extended their lifespan • Why a 200-year-old whale has 100x more of a DNA-repair protein than humans — and whether cold plunges can activate it • Why longer telomeres don't make you live longer, and can raise cancer risk instead • How a gene variant found in human centenarians led to a seaweed compound that extended mouse lifespan 15% • How controlling the "dark genome" nearly doubled mice's reproductive lifespan, and what that might mean for delaying menopause • Why biological age tests can swing by years on the same day — and how to actually use them • Why the researchers say most anti-aging supplements are unproven — and which ones they still take themselves Connect with Dr. Vera Gorbunova: https://www.linkedin.com/in/vera-gorbunova-64a97b46/ Connect with Dr. Andrei Seluanov: https://www.linkedin.com/in/andrei-seluanov-52055b62/ Connect with our host Chris Wharton on Instagram: instagram.com/chriswharton1 Follow The LIVING Room Podcast on Socials: • Instagram: https://www.instagram.com/the.living.room.pod/ • LinkedIn: linkedin.com/company/wndrlab/ • The WNDR Lab: https://www.thewndrlab.com/ Want to learn more?
