摘      要：Objective To further explore associated effects of Lactobacillus plantarum dy-1(LFBE) on obesity and lipid metabolism at the gene expression level, the expression of micro RNAs(mi RNAs) was investigated in the liver of high-fat diet(HFD) induced obese rats.Methods Three groups of animal models were established. Changes in mi RNA expression in the liver of each group were analyzed by microarray and RT-q PCR, complemented by bioinformatics. Palmitateinduced hepatocellular carcinoma(Hep G2) cells were used as a model to validate the test.Results LFBE treatment groups and HFD groups were observed to be distinctly different with respect to rates of increase in body weight and body fat percentage and triglyceride(TG) and total cholesterol(TC) levels in serum and liver. In addition, the LFBE group showed upregulation of ten mi RNAs and downregulation of five mi RNAs in the liver. Downregulation of mi R-34 a and mi R-212 was observed in the livers of the LFBE group. Gene ontology and kyoto encyelopedia of geues and genomes(KEGG)pathway analysis showed that possible target genes of the deregulated mi RNAs were significantly enriched in the adrenergic and HIF-1 signaling pathways.Conclusion These results demonstrate that LFBE might regulate the expression of mi RNAs in order to inhibit obesity and fatty liver.
