Except for the above-mentioned molecules, evidence has shown that AMPK reduces hepatic steatosis in high-fat, high-sucrose (HFHS) diet-fed mice by interacting with and mediates phosphorylation of insulin-induced gene (Insig), a novel effector of AMPK, which plays a critical role in regulating intracellular cholesterol equilibrium [60]. Here, PRKAA2 is linked to fatty liver disease.
