Abstract
AIM: To investigate the effects of low-dose all-trans-retinoic acid (ATRA) supplementation on the concentrations of hepatic retinoids, formation of polar retinoid metabolites (PRMs), expression of microsomal cytochrome P4502E1 (CYP2E1) and liver injury in ethanol-fed rats.
METHODS: A rat model of alcoholic liver disease (ALD) was induced by intragastric infusion of ethanol. Thirty male SD rats were randomly assigned to four groups: group A was a control group, rats of groups B, C and D were received intra-gastric infusion of alcohol (8 g/kg) for 8 weeks, and rats of groups C and D were administered all-trans-RA at two different doses (150 µg/kg body wt in group C and 1.5 mg/kg body wt in group D), by intragastric infusion, for 4 weeks. The concentrations of retinoids in rat liver were detected using high-performance liquid chromatography (HPLC), the levels of CYP2E1 were measured by Western blotting, and pathological changes in the livers were observed under light microscope ......
