Mst1 regulates hepatic lipid metabolism by inhibiting Sirt1 ubiquitination in mice
چکیده انگلیسی
Previous study showed mammalian Ste20-like kinase (Mst1) may serve as target for the development of new therapies for diabetes. However, the function of Mst1 involved in liver lipid metabolism has remained elusive. In this study, we report that the liver of Mst1 knockout (Mst1−/−) mice showed more severe liver metabolic damage under fasting and high-fat diet than that of control mice. And fasting induced hepatic Mst1 expression. Mst1 overexpression inhibited Srebp-1c expression and increased the expression of antioxidant genes in primary hepatocytes. We also found that fasting-induced expression of hepatic Sirt1 was attenuated in Mst1−/− mice. Mst1 overexpression promoted Sirt1 expression, probably due to inhibiting Sirt1 ubiquitination. In summary, our study suggests that Mst1 regulates hepatic lipid metabolism by inhibiting Sirt1 ubiquitination in mice.
