摘要
The activation of the Wnt/β-catenin signaling pathway in oval cells after liver injury is implicated in hepatocarcinogenesis.Diwu Yanggan capsule is a Chinese herbal medicine that has been used for treating liver disorder.The present study aimed to examine the mechanism by which Diwu Yanggan inhibits liver carcinogenesis,and the involvement of the Wnt/β-catenin signaling pathway.Diwu Yanggan capsule was administered to 2-acetaminofluorene/partial hepatectomy(2-AAF/PH)rats,a murine model of liver injury.The biomarkers of oval cells and key proteins in the Wnt/p-catenin signaling pathway were assessed on postoperative day 8,10,14,17,19 and 22.The results showed that treatment with Diwu Yanggan was associated with reduced expression of oval cell and stem cell biomarkers in the 2-AAF/PH animals.The expression pattern of key proteins in the Wnt/β-catenin pathway was altered in Diwu Yanggan-treated animals,indicating that the Diwu Yanggan treatment accelerated the activation of the Wnt/β-catenin pathway in the initial stage and contributed to its deactivation in the later stage.Histological findings indicated that hepatocyte proliferation was suppressed in Diwu Yanggan-treated animals,compared with untreated 2-AAF/PH animals.Taken together,Diwu Yanggan capsule may reduce the risk of hepatocarcinogenesis by modulating the Wnt/β-catenin signaling pathway.
