Therefore, cAMP signaling pathway, Hippo signaling pathway, PPAR signaling pathway, Fat digestion and absorption signaling pathway, Regulation of lipolysis in adipocyte signaling pathways, Adipocytokine signaling pathway, AMPK signaling pathway and Non-alcoholic fatty liver disease (NAFLD) signaling pathway are the main signal pathway regulating intramuscular fat. Here, PPARA is linked to metabolic dysfunction-associated steatotic liver disease.
