E119: Gordon Lithgow talks about the biology of aging and prolonging lifespan

Описание: Full show notes: https://www.ihmc.us/stemtalk/episode-...

Our guest today is Dr. Gordon Lithgow, a professor and vice president of Academic Affairs at the Buck Institute in Novato, California. Gordon’s research focuses on uncovering genes and small molecules that prolong lifespan through enhanced molecular stability.

Because our conversation with Gordon was so extensive and fascinating, we have split his interview into two parts. In today’s part one of the interview, we talk to Gordon about his background and early studies as well as his fascination with C elegans, a microscopic worm that Gordon and other geneticists study and often use for their research. We particularly talk in depth about two of Gordon’s studies involving C elgans: one that looked at the role that protein homeostasis plays in aging;  and another study that found vitamin D3 improves protein homeostasis and slows aging.

A native of Scotland, Gordon researched the biology of aging at the University of Manchester in England before moving to the Buck Institute in 2000. Gordon is married to Dr. Julie Andersen, who was our guest on episodes 117 and 118 and who also is a researcher at the Buck Institute.

In part two of our interview with Gordon, we talk to him about a recent study of his that found the naturally occurring metabolite alpha-ketoglutarate reduces inflammatory signaling as well as chronic inflammation. The study has generated quite a bit of buzz because it suggests there’s a readily available metabolite that may have positive effects on lifespan and health span. As a result, Ken and Dawn have been getting numerous questions from listeners about alpha-ketoglutarate and Gordon’s recent study that ran in Cell Metabolism, which Gordon talks about in depth in part two.
