MTOR and metabolic dysfunction-associated steatotic liver disease: The pivotal role of mTOR in the regulation of metabolism, lipid biosynthesis, fibrogenesis, and NAFLD/NASH progression was confirmed with the help of omics techniques, and the close relationship with IGF1, TGF-β/SMAD, SREBP, PPARs, and other important cellular regulators was reported in human and animal studies [13,14,15].
