| Outline of Final Research Achievements |
PS-B1 is fermented products using lactic acid bacteria, which showed inhibitory effect on hepatic transcription factor ChREBP-mediated gene expression in vitro. The present study evaluated the effect of PS-B1 on high sucrose diet-induced obesity in mice. The weight gain of overall body, liver, and visceral fat was reduced in the PS-B1 treated mice in a dose-dependent way. Besides, mRNA expression of hepatic glycolytic and lipogenic enzymes including L-PK, ACC, FAS etc. was significantly lower especially in 5% PS-B1-treated mice. The results of this study suggest that PS-B1 inactivates ChREBP-mediated gene expression, resulting in reduced fat synthesis and obesity in vivo.
