Abstract

We investigated the effects of ciprofibrate, a potent peroxisome proliferator, on ethanol metabolism in mice. The blood alcohol levels of mice fed a liquid diet containing both ciprofibrate and ethanol were markedly depressed compared with mice fed the ethanol-containing diet alone. Ciprofibrate markedly induced enoyl-CoA hydratase/3-hydroxyacyl-CoA dehydrogenase, hydrogen peroxide, and to a lesser extent catalase in both control and ethanol-diet fed mice. Northern blot analysis indicated no significant upregulation of cytochrome P450IIE1 mRNA by ciprofibrate. Our study suggests that peroxisome proliferators increase ethanol catabolism through hydrogen peroxide production, thus allowing utilization of the catalase pathway. These findings indicate that catalase has the potential to provide a significant pathway for ethanol metabolism under conditions of peroxisome proliferation.
