Work in the GERAM (Gene Expression Regulation of Aging and Metabolism) lab, directed by Dr. Rhoads, focuses on understanding the molecular regulation of aging and metabolism through the use of caloric restriction (CR). CR is a dietary intervention and model of delayed aging; CR results in extended lifespan in numerous model organisms. This is of direct relevance for human health, as advanced age is the largest risk factor for numerous chronic diseases – cancer, diabetes, cardiovascular disease, and neurodegeneration, to name a few. However, the molecular mechanisms connecting reduced caloric intake with enhanced longevity and reduced chronic disease vulnerability remain poorly understood. The GERAM lab focuses on mechanisms of gene expression regulation, including protein post-translational modification, mRNA processing, and expression regulation via endogenous small RNA. Tools used include both wet lab and dry lab analytical methods, with a substantial interest in integrative models that produce systems-level insights.
