AIM:To determine the therapeutic efficacy of resveratrol on ulcerative colitis(UC) and its underlying mechanisms.METHODS:The mouse UC model was developed using 5% dextran sulfate sodium.Mice were randomly divided into four groups:normal control,UC model group,resveratrol low-dose group(RLD; 50 mg/kg per day),and resveratrol high-dose group(RHD; 100 mg/kg per day).RESULTS:The results showed that RLD regulates Treg/Th17 balance mainly through reducing the number of Th17 cells,whereas RHD regulates Treg/Th17 balance through both downregulating the number of Th17 cells and upregulating the number of Treg cells.Resveratrol can also regulate the level of plasma and intestinal mucosal cytokines including interleukin(IL)-10,transforming growth factor-β1,IL-6,and IL-17.The expressions of hypoxia inducible factor(HIF)-1α,mammalian target of rapamycin(m TOR),and signal transducer and activator of transcription 3 weresignificantly decreased in the intestinal tissues of mice treated with resveratrol.CONCLUSION:The therapeutic efficacy of resveratrol in UC is dose dependent and closely associated with the regulation of Treg/Th17 balance and the HIF-1α/mT OR signaling pathway.
