Dr. Sack’s laboratory focuses on modifications of proteins that play pivotal roles in metabolism and mitochondrial function to understand how these modifications affect disease risk. The major regulatory proteins being explored in the Sack laboratory include SIRT3, GCN5L1 and Parkin. The effects of these nutrient- and stress-regulatory proteins on mitochondrial biology and metabolism are explored in the context of disease pathophysiology with studies in both experimental systems with translation to the human subjects. The objective of these studies are to understand how nutrient- and other stress- signaling events cause or exacerbate disease and whether therapeutic interventions can be tested that reverse these pathologies. Current diseases being explored include cardiovascular disease, immune activation and Early Onset Parkinson Disease.
