In agreement with this concept, several studies demonstrated that the effects of the Sct/SR signaling axis on biliary damage and liver fibrosis are mediated by paracrine modulation of TGFβ1 biliary secretion that leads to activation/deactivation of HSCs and changes in liver fibrosis through modulation of liver angiogenesis [9, 16, 17]. This evidence concerns the gene SCT and Hepatic fibrosis.
