DiscoveryNutrition and exercise interventions have the potential to attenuate the development of insulin resistance, decrease chronic inflammation and reduce the risk of developing cardiovascular disease risk and metabolic syndrome. Our laboratory is interested in continuing to develop research lines to elucidate mechanisms whereby various nutritional and exercise interventions alter the chromatin state and crosstalk between nuclear and mitochondrial compartments, essentially epigenetically programming mitochondrial adaptation in lean, insulin sensitive or obese, insulin resistant states. We are currently utilizing both clinical and cellular models to determine 1) the effects of dietary fat and/or exercise training on the chromatin state within skeletal muscle that results in differential cellular phenotypes, metabolomes (acylcarnitine profiles) and whole body energy expenditures and phenotypes, focusing on nucleosome reorganization; and 2) epigenetic regulation of PGC1a in skeletal muscle by supplementation with the botanical extract, quercetin, or the metabolite produced by dietary fiber fermentation, butyrate. Understanding the epigenetic mechanisms whereby nutrition and physical activity regulate nuclear gene expression and coordinate with downstream mitochondrial gene expression to determine mitochondrial number and function is crucial in understanding, treating and preventing obesity and type 2 diabetes.
