Understanding Aging to Extend Healthspan and Longevity with Dr. Gordon Lithgow
In this episode of Longevity by Design, hosts Ashley Reaver, MS, RD, CSSD, and Dr. Gil Blander sit down with Dr. Gordon Lithgow, a Professor and Vice President for Academic Affairs at the Buck Institute for Research on Aging. Dr. Lithgow's research focuses on understanding the mechanisms of aging and identifying genes and small molecules that can prolong lifespan. With a background in genetics from the University of Glasgow and extensive experience in biotechnology and aging research, Dr. Lithgow shares his journey from growing up in Scotland to leading a lab at the Buck Institute.
Dr. Lithgow discusses the compelling nature of aging as a profound biological mystery, which drew him into the field. He highlights his lab's approach of following curiosity-driven research, often using the nematode worm C. elegans as a model organism due to its short lifespan and genetic similarities to humans. This unbiased method has led to significant discoveries, including genetic mutations and drug-like molecules that extend lifespan. The conversation also covers the concept of geroscience, which Dr. Lithgow helped coin, emphasizing the link between aging and chronic diseases.
A major focus of Dr. Lithgow’s work is studying protein homeostasis, which declines with age. Protein misfolding is implicated in many age-related diseases; that discovery moved the lab’s focus from lifespan extension to efforts to understand drivers of healthspan and the causes of age-related chronic diseases, in particular Alzheimer’s and Parkinson’s. His work also includes the influence of environmental factors, such as mild heat stress, and dietary iron, vitamin D, and alpha-ketoglutarate (AKG) on aging. Dr. Lithgow's interdisciplinary collaborations aim to uncover new interventions to extend healthspan and longevity.
Dr. Gordon Lithgow is also the host of Buck Institute for Research on Aging's podcast, "We're not getting any younger... yet" on which he speaks with some of the brightest scientific stars on the planet to search for—and actually find answers to—questions on aging.
