Objective To investigate the effect of reversine (REV) on bile duct ligation (BDL) -induced hepatic damage, fibrosis, epithelial-mesenchymal transformation, and ductular reaction in rats. Methods Male Lewis rats were randomly divided into three groups with 5 rats in each group. Bile duct ligation was performed in the BDL group for two weeks. BDL+ REV group was treated with bile duct ligation and intraperitoneal injection of reversine. The control group was Sham operation (Sham). Blood and liver tissue were obtained after 2 weeks. Blood indexes were determined for total albumin, total bilirubin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and γ-glutamyl transpeptidase. Hepatic histopathology was detected by H&E staining. Azan staining was used to detect tissue collagen deposition. Immunohistochemistry was used to detect the expression of α-SMA, desmin, vimentin, cytokeratin, β-catenin and epithelial cell adhesion molecule (EpCAM) protein. Results Bile duct ligation resulted in the decrease of total albumin synthesis in liver, and the increase of total bilirubin, glutamic-oxalacetic transaminase, alkaline phosphatase and γ-glutamyltranspeptidase. The levels of total bilirubin, aspartate transaminase, alkaline phosphatase and γ-glutamyltranspeptidase returned to the normal level with reversine treatment. Reversine could alleviate cholestasis-induced liver fibrosis by downregulating BDL-induced deposition of collagen and α-SMA protein. Reversine inhibited cholestasis-induced epithelial-mesenchymal transformation by significantly reducing BDL-induced desmin and vimentin expression. Reversine could inhibit cholestasis-induced ductular reaction by significantly reducing the expression of CK7 and CK19 positive biliary cells. Inhibition of cholestasis induced ductular reaction by reversine was associated with regulation of β-catenin and EpCAM expression. Conclusion Reversine can alleviate liver damage caused by cholestasis in rats and have a protective effect. Reversine may be a potential treatment that need further investigation.
