TGFB1 and Hepatic fibrosis: The expressions of known genes in liver damage were studied, such as tissue inhibitors of metalloproteinases (such as Timp1) that can inhibit matrix degradation; transforming growth factor beta-1 (such as Tgfb1), a known inducer of fibrogenesis in the effector cells of hepatic fibrosis that can stimulate adipocyte transformation; and peroxisome proliferator-activated receptor (Pparg) transcription factor, involved in the signaling pathway of lipid metabolism.
