In rat liver microsomes, all-trans-[11,12-3H]retinoic acid was found to be metabolized to polar products in the presence of NADPH. One of the metabolites was coeluted with 4-hydroxyretinoic acid on reverse-phase high-pressure liquid chromatography (HPLC). This reaction required oxygen and was inhibited by carbon monoxide as well as aminopyrine, aniline, and ethanol, suggesting the involvement of cytochromeP-450. Isolated rat hepatocytes also metabolized all-trans[3H]retinoic acid to polar compounds, with an elution pattern on HPLC similar to that in microsomal preparations. Microsomal activity was compared in rats pair-fed with diets containing either ethanol or isocaloric carbohydrate for 4–6 weeks. Ethanol-fed rats showed enhanced microsomal retinoic acid metabolism (50%,P< 0.01) accompanied by increased microsomal cytochromeP-450 content (34%,P< 0.005). On the other hand, microsomal β-glucuronidation of retinoic acid in the presence of uridine diphosphoglucuronic acid (UDPGA) was not affected by chronic ethanol feeding. The increased hepatic microsomal cytochromeP-450-dependent metabolism of retinoic acid after chronic ethanol consumption may contribute to the accelerated catabolism of retinoic acidin vivo.
