Hepatocyte Clock And Alcohol-Dependent Disruption In Glycogen Metabolism, Uduak Sunday Udoh

All ETDs from UAB

Chronic alcohol consumption has been shown to significantly decrease hepatic glycogen, an important storage form of energy for the body and liver. Emerging studies indicate a link between metabolism and the molecular circadian clock. Previously, we have shown that chronic alcohol consumption disrupts the liver molecular clock mechanism. However, it is not known how this alteration impacts hepatic energy (e.g., glycogen) metabolism and contributes to alcohol hepatotoxicity. This dissertation investigates the impact chronic alcohol consumption has on time-of-day-dependent oscillations of various aspects of liver glycogen metabolism, and the importance of the liver circadian clock in these metabolic alterations.
