MicroRNA-17-5p-activated Wnt/β-catenin pathway contributes to the progression of liver fibrosis.

ABSTRACT: Aberrant Wnt/β-catenin pathway contributes to the development of liver fibrosis. MicroRNAs (MiRNAs) are found to act as regulators of the activation of hepatic stellate cell (HSC) in liver fibrosis. However, whether miRNAs activate Wnt/β-catenin pathway in activated HSCs during liver fibrosis is largely unknown. In this study, we found that Salvianolic acid B (Sal B) treatment significantly inhibited liver fibrosis in CCl4-treated rats, HSC-T6 cells and rat primary HSCs, resulting in the suppression of type I… collagen and alpha-smooth muscle actin. Also, Sal B suppressed HSC activation and cell proliferation in vitro. Interestingly, Sal B treatment induced the inactivation of Wnt/β-catenin pathway, with an increase in P-β-catenin and Wnt inhibitory factor 1 (WIF1). We demonstrated that th
