Abstract:
Objective:To study the effect of Biejia Jianwan on expressions of signal molecules and target genes of transforming growth factor-β (TGF-β)/Smad pathway in diethylnitrosamine (DEN)-induced rat hepatocellular carcinoma, and explore the mechanisms of Biejia Jianwan suppressing the invasion of hepatocellular carcinoma. Method:The rats were divided into three group, namely normal group, model group and Biejia Jianwan group (2.2 g·kg-1·d-1). Rats in Biejia Jianwan group and model group received intraperitoneal injections of DEN to induce sequential chronic inflammation, cirrhosis and hepatocellular carcinoma. At the sign of cirrhosis, rats in Biejia Jianwan group began taking Biejia Jianwan by gavage for 6 weeks. Rat blood was collected to measure serum levels of biochemical markers of liver function tests, including alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bilirubin(TBIL), albumin(Alb), γ-glutamyl transpeptadase(GGT), alkaline phosphatase(ALP). Rat livers were fixed in formalin and stained with hematoxylin-eosin (HE)staining， quantitative real-time PCR was used to test the mRNA expressions of TGF-β1， and Western blot was used to test protein expressions of TGF-β1, Smad2/3, p-Smad2/3, N-cadherin, E-cadherin and Vimentin. Result:All of the levels of biochemical markers showed no difference in Biejia Jianwan group and model group. Biejia Jianwan could improve the pathological changes of balloon-like degeneration, edema, and necrosis in liver cancer tissues. Importantly, the treatment dramatically decreased the mRNA expression of TGF-β1(P<0.01), and the protein expressions of TGF-β1, p-Smad2(P<0.01). Besides, the protein expression of N-cadherin and Vimentin were decreased significantly (P<0.01). Conclusion:Biejia Jianwan can inhibit epithelial-mesenchymal transition (EMT) in hepatocellular carcinoma cells activated via TGF-β/Smad pathway by reducing TGF-β1 expression, so as to suppress the metastasis and invasion of hepatocellular carcinoma.
