摘要: 目的 观察中药肝复康含药血清对肝星状细胞T6(HSC-T6)细胞株经典Wnt信号转导通路中的关键调节因子Wnt1、糖原合成激酶3β(GSK-3β)、β-链蛋白(β-catenin)、细胞周期蛋白D1(cyclinD1)以及α-平滑肌动蛋白(α-SMA)基因表达的影响,探讨其抗纤维化的作用及分子机制。方法 制备肝复康含药血清,用乙醛及肝复康含药血清干预HSC-T6细胞株,采用RT-PCR和Western-Blot法分析Wnt1、Gsk-3β、β-catenin、cyclinD1和α-SMA表达的变化。结果 肝复康含药血清处理可上调HSC-T6细胞株Gsk-3βmRNA的表达,下调Wnt1、β-catenin、cyclinD1和α-SMA的表达。结论 肝复康对肝纤维化具有明显的抑制作用,其作用机制可能是通过调节经典的Wnt信号通路中的关键因子的表达,从而抑制α-SMAmRNA的转录,以减少细胞外基质的形成。

Abstract: Objective To study the effect of Ganfukang compound,a Chinese traditional herb medicine,on the expression of some regulatory factors of Wnt signaling pathway in hepatic stellate(HSC)-T6 cells. Methods HSC-T6 was dealt with middle concentration of Ganfukang compound. The expression changes of Wnt1,Gsk-3β,β-catenin,cyclinD1 and α-SMA were analysed by RT-PCR and Western-blot. Results Except Gsk-3β,the expression of Wnt1,β-catenin,cyclinD1 and α-SMA were downregulated after treated with Ganfukang compound. Conclusion The anti-fibrosis roles of Ganfukang compound are related to several key regulatory factors in Wnt/β-catenin pathway,which might inhibit the transcription of α-SMA and decrease the production of extracellular matrix.
