A B S T R A C T To investigate whether resveratrol could ameliorate the hepatic steatosis in high-fat diet (HFD) fed mice by modulating gut microbiota composition, fecal microbiota transplantation (FMT) was utilized in this study. Our results showed that resveratrol significantly ameliorated hepatic steatosis in HFD mice, increased the gene expression of fasting-induced adipose factor, and decreased the expression of lipogenesis-related genes and proteins (SREBP-1, FAS and ACC). In addition,

... veratrol reversed HFD-induced gut microbiota dysbiosis, with an increase in the relative abundance of Bacteroidetes and a decrease in that of Firmicutes and Proteobacteria. Subsequent results showed the gut microbiota compositions of FMT recipient groups were similar to those of corresponding donor groups. And the changes of state of hepatic steatosis and expression of SREBP-1, ACC and FAS were coordinated with the results of gut microbiota. In conclusion, these results provided evidence to support the resveratrol could ameliorate the hepatic steatosis by modulating the gut microbiota.
