Electronic Theses and Dissertations
Alcohol induced hepatic steatosis is a significant risk factor for progressive liver disease. Steatotic hepatocytes have increased sensitivity to injury produced by inflammatory cytokines, particularly TNF. Cyclic adenosine monophosphate (cAMP) has been shown to play a significant role in the regulation of both TNF production and lipid metabolism. However, the role of altered cAMP homeostasis in alcohol mediated hepatic steatosis and injury has not been studied. cAMP levels are tightly regulated by phosphodiesterase family of enzymes. Our recent work demonstrated that increased expression of hepatic PDE4, which specifically hydrolyzes and decreases cAMP levels, plays a pathogenic role in the development …
