Lactobacillus casei YRL577 combined with plant extracts reduce markers of non-alcoholic fatty liver disease in mice.

This study explores the effects of using both probiotics and plant extracts on NAFLD. This study evaluated the effects of plant extracts on lipid droplet accumulation and the growth of probiotics in vitro. A C57BL/6 mouse model was used to examine the effects of probiotics and plant extracts on NAFLD. The body weight and food intake were measured. The levels of serum lipids, oxidative stress, and the liver injury index were determined using commercial kits. HE staining, gas chromatography and Real-Time PCR were also used for analysis. The results revealed that administration of Lactobacillus casei YRL577 and Lactobacilli paracasei X11 with resveratrol (RES) or tea polyphenols (TP) significantly reduced the levels of total cholesterol (TC), triacylglycerols (TG) and low-density lipoprotein cholesterol (LDL-C) and increased the level of the high-density lipoprotein cholesterol (HDL-C). The groups of L. casei YRL577 with RES and TP also regulated the liver structure, oxidative stress, and injury. Furthermore, L. casei YRL577 with TP exhibited a more positive effect toward improving the NAFLD and increased the concentrations of the butyric acid than other three combined groups. L. casei YRL577 with TP up-regulated the mRNA levels of the farnesoid X receptor (FXR) and fibroblast growth factor 15 (FGF15) and decreased the mRNA levels of the apical sodium-dependent bile acid transporter (ASBT). These findings showed that L. casei YRL577 + TP modified genes in the intestinal bile aci...
