摘要 目的探讨体外条件下转化生长因子β1(TGF-β1)对大鼠血管平滑肌细胞(VSMCs)Smad泛素调节因子2(Smurf 2)以及Ⅰ型胶原(ColⅠ)表达的影响。方法应用RT-PCR法检测Smurf2 mRNA的表达,Western印迹法检测Smurf2蛋白的表达,ELISA检测ColⅠ的表达。结果不同浓度TGF-β1(1、5、10μg/L)作用于VSMCs后,细胞中Smurf2的表达量均低于对照组(P<0.05),且5、10μg/L组同对照组相比差异显著(P<0.01),ColⅠ的浓度高于对照组(P<0.05),且5μg/L组同对照组相比差异显著(P<0.01)。结论 TGF-β1呈浓度依赖性抑制Smurf2的表达,促进ColⅠ的产生。
