Mitochondria are known as the "engines" of the cell, converting metabolites into a useable form of energy for the rest of the cell. Overloading cells with fuel due to excess caloric intake and/or inactivity compromises mitochondrial function whereas exercise training enhances mitochondrial oxidative capacity. Research in my lab is directed at deciphering the molecular mechanisms governing mitochondrial bioenergetics and function in the context of the etiology of metabolic disease as well as disease prevention/treatment.
NIH RO1 DK073488 Mitochondrial Bioenergetics and Etiology of Insulin Resistance (04/30/11). The long term objective of this research is to determine if the loss of mitochondrial function and insulin sensitivity stem from a common metabolic disturbance, i.e., oxidative stress. The projects utilize a newly developed permeabilized fiber approach to study mitochondrial function in rodent skeletal muscle, pharmacological agents and transgenic models to manipulate mitochondrial ROS production and scavenging.
NIH RO1 DK074825 Linking Mitochondrial Bioenergetics to Muscle Insulin Sensitivity (01/31/14). This project examines the potential link between mitochondrial function/dysfunction and insulin sensitivity in 1) obese humans 2) younger subjects of normal weight and with normal insulin sensitivity acutely exposed to high caloric/high fat diet; and 3) in obese subjects undergoing a diet/exercise intervention to reverse insulin resistance.
