Hepatocyte retinoid X receptor alpha (RXRalpha)-deficient mice are more sensitive to ethanol toxicity than wild-type mice. Because RXRalpha-mediated pathways are implicated in lipid homeostasis and the inflammatory response, we hypothesized that a compromise in lipid metabolism and associated production of proinflammatory mediators are responsible for the hepatotoxicity observed in ethanol-trea...

The hypoxia-sensing transcriptional factor HIF1α is implicated in a variety of hepato-pathological conditions; however, the contribution of hepatocyte-derived HIF1α during progression of alcoholic liver injury is still controversial. HIF1α induces a variety of genes including those involved in apoptosis via p53 activation. Increased hepatocyte apoptosis is critical for progression of liver infl...
