Ever since Cell Metabolism published a study that found the naturally occurring metabolite alpha-ketoglutarate reduces inflammatory signaling as well as chronic inflammation, listeners have been asking Ken and Dawn for their take on the paper. Today, we have the author of the paper, Dr. Gordon Lithgow, as our guest on STEM-Talk. We talk with Gordon in-depth about his study and the potential of alpha-ketoglutarate to have positive effects on lifespan and healthspan.

Gordon is a professor and vice president of Academic Affairs at the Buck Institute in Novato, California, where his research focuses on uncovering genes and small molecules that prolong lifespan through enhanced molecular stability. Today we cover Gordon’s research into alpha-ketoglutarate in the second part of a two-part interview. In part one, episode 119, we asked Gordon about his fascination with C elegans, a microscopic worm that Gordon and other geneticists study and often use for their research. He particularly covered two of his 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.
