title: Silibinin inhibits ethanol metabolism and ethanol-dependent cell proliferation in an in vitro model of hepatocellular carcinoma.
abstract: Chronic ethanol consumption is a known risk factor for developing hepatocellular carcinoma (HCC). The use of plant-derived antioxidants is gaining increasing clinical prominence as a potential therapy to ameliorate the effects of ethanol on hepatic disease development and progression. This study demonstrates silibinin, a biologically active flavanoid derived from milk thistle, inhibits cytochrome p4502E1 induction, ethanol metabolism and reactive oxygen species generation in HCC cells in vitro. These silibinin-mediated effects also inhibit ethanol-dependent increases in HCC cell proliferation in culture.
