Inhibition of ethanol-induced liver disease in the intragastric feeding rat model by chlormethiazole.

The purpose of this investigation was to assess the effect of chlormethiazole treatment on liver damage in the experimental rat intragastric ethanol-feeding model of alcoholic liver disease. Chlormethiazole has been used in the treatment of alcoholic withdrawal and has been shown to inhibit cytochrome P4502E1. Since treatment of experimental alcoholic liver disease with CYP2E1 inhibitors had an ameliorating effect on liver injury in the rat, chlormethiazole was used to see if it had a similar effect.

Role of CYP2E1 in the pathogenesis of alcoholic liver disease: modifications by cAMP and ubiquitin-proteasome pathway.

The ethanol inducible isoform of cytochrome P450, CYP2E1, may play a role in ethanol-induced liver injury. Therefore, the factors which govern CYP2E1 degradation and turnover were investigated. These factors include cAMP, ubiquitin, proteasomal enzymes and CYP2E1 mRNA.
