Abstract

Abstract: Molecular targeted agents are pharmacologically used to treat liver fibrosis and have gained increased attention. The present study examined the preventive effect of lenvatinib on experimental liver fibrosis and sinusoidal capillarization as well as the in vitro phenotypes of hepatic stellate cells. LX‐2, a human stellate cell line, was used for in vitro studies. In vivo liver fibrosis was induced in F344 rats using carbon tetrachloride by intraperitoneal injection for 8 weeks, and oral administration of lenvatinib was started two weeks after initial injection of carbon tetrachloride. Lenvatinib restrained proliferation and promoted apoptosis of LX‐2 with suppressed phosphorylation of extracellular signal‐regulated kinase 1/2 and AKT. It also down‐regulated COL1A1, ACTA2 and TGFB1 expressions by inhibiting the transforming growth factor‐β1/Smad2/3 pathway. Treatment with lenvatinib also suppressed platelet‐derived growth factor‐BB‐stimulated proliferation, chemotaxis and vascular endothelial growth factor‐A production, as well as basic fibroblast growth factor‐induced LX‐2 proliferation. In vivo study showed that lenvatinib attenuated liver fibrosis development with reduction in activated hepatic stellate cells and mRNA expression of profibrogenic markers. Intrahepatic neovascularization was ameliorated with reduced hepatic expressions of Vegf1, Vegf2 and Vegfa in lenvatinib‐treated rats. Collectively, these results suggest the potential use of lenvatinib as a novel therapeutic strategy for liver fibrosis.
