TGFB1 and metabolic dysfunction-associated steatohepatitis: In proteomic studies with human NASH-associated biopsies, in addition to alteration proteins associated with inflammation, lipid deposition, insulin resistance, and oxidative stress, significant elevation of numerous ECM and cytoskeleton proteins, with the majority being downstream of TGF-β, including different collagens, fibronectin, vimentin, beta actin-like protein 2, tropomyosin α-4 chain, myosin 9, tubulin α-1C chain, moesin, and others, have been demonstrated [13,68].
