Research Abstract

Metabolism in different tissues/organs is regulated via both neuronal and humoral factors. We have previously demonstrated that neuronal networks, especially from the liver, play important roles in maintaining metabolic homeostasis among organs/tissues, including adipose tissue and pancreatic islets. Nutrient (carbohydrate, fat, and protein) overloads due to overeating affect these regulational systems, resulting in progression of metabolic disorders. In this study, we purpose to identify a new role of hepatic amino acid metabolism on the development of metabolic syndrome.
