Alcohol consumption causes alteration in several cellular mechanisms, and leads to inflammation, apoptosis, immunoresponse defect, and fibrosis. These phenomena are associated to significant changes in the epigenetic mechanisms, and, subsequently, to the liver cell memory. Although inhibition of proteasome function has been widely reported in models of alcoholic liver disease (ALD), why proteasome dysfunction may enhance hepatotoxicity is not well defined. In addition, there is no evidence of the effect of ethanol feeding on the activity of nuclear proteasome and the consequences of proteasome inhibition in epigenetic mechanisms and DNA repair...
