PPARG and metabolic dysfunction-associated steatotic liver disease: Western blot revealed that PP1 inhibited the lipid accumulation and fatty acid synthesis in 3T3-L1 adipocytes in two pathways, primarily: nonalcoholic fatty liver disease (NAFLD) pathway (C/EBPα, SREBP-1c, AMPKα) and AMPK signaling pathway (SREBP-1c, PPARγ, AMPKα).
