The importance of CYP2E1 in the pathogenesis of alcoholic liver disease and drug Toxicity and the role of the proteasome

Abstract

The chapter discusses about the critical role of CYP2E1 in ethanol mediated liver injury and its association with NASH. Ethanol metabolism by CYP2E1 generates hydroxyethyl radicals which promote ethanol hepatotoxicity. Greater induction of CYP2E1 and hence greater liver injury occurs with co-administration of ethanol and drugs. Induction of CYP2E1 leads to prominent epigenetic effects and CYP2E1 polymorphism may be associated with alcoholic liver disease. These are some aspects of CYP2E1, amongst many others which account for its importance in the context of drug metabolism and disease development and have been reviewed in the chapter.
