Abstract<\/h6>\n

Calorie restriction (CR), or reducing calorie intake without malnutrition, robustly extends lifespan in model organisms ranging from yeast to mammals. CR restricts the intake of all macronutrients (protein, carbohydrate, and fat), but whether the effects of a CR diet are mediated solely by reduced caloric intake or reduced consumption of specific macronutrients has long been unclear.<\/p>\n

Over the last decade, research in organisms including flies and mice has highlighted a critical role for dietary protein in mediating longevity, with reduced consumption of dietary protein promoting longevity and improving metabolic health. However, the specific dietary components altered in a low protein diet that promote health and longevity remain unknown. In this talk, I will discuss ongoing research in my laboratory into the role of the three branched-chain amino acids (BCAAs; leucine, isoleucine, valine) in regulating metabolic health and longevity.<\/p>\n

Research profile<\/h6>\n

Dr. Lamming completed his PhD in Experimental Pathology with Dr. David Sinclair at Harvard University in 2008, and then performed postdoctoral research at the Whitehead Institute for Biomedical Research with Dr. David Sabatini. In 2014, he joined the faculty of the University of Wisconsin-Madison, where he is an Assistant Professor of Medicine, and co-directs the UW-Madison Department of Medicine Mouse Metabolic Phenotyping Platform. He has a joint appointment as a Research Health Scientist with the William S. Middleton Memorial Veterans Hospital.<\/p>\n

Dr. Lamming is primarily focused on understanding the regulation of aging and metabolism by nutrient signaling pathways, including the mechanistic target of rapamycin (mTOR), and specific dietary macronutrients. His laboratory recently determined that low protein diets promote metabolic health \u2013 improving blood sugar control and reducing adiposity \u2013 in humans and mice, and identified dietary branched-chain amino acids (BCAA) as key regulators of these effects. His laboratory is now investigating the molecular and physiological mechanisms by which BCAAs regulate metabolic health, and is exploring the possibility that specifically modulating dietary BCAAs can treat or prevent metabolic syndrome, other age-related diseases, and promote longevity and healthspan.<\/p>\n
