Fasting and high-fat diet aggravate liver metabolic damage in Mst1−/− mice.
Mst1 decreases Srebp-1c expression and increases antioxidant genes expression.
Fasting-induced hepatic Sirt1 increase is attenuated in Mst1−/− mice.
Mst1 increases the expression of Sirt1 by inhibiting Sirt1 ubiquitination.
