摘要:目的:探讨糖耐康(TNK)含药血清对转化生长因子-β1(TGF-β1)诱导的人肾小管上皮细胞(HK-2)转分化Smad信号通路的影响。方法:将HK-2细胞用含10%胎牛血清的DMEM/F12(1∶1)培养基培养;实验分为6组:空白对照组、单纯TGF-β1诱导组(TGF-β110μg·L-1)、空白血清对照组(TGF-β110μg·L-1+10%空白血清)、TNK高浓度组(TGF-β110μg·L-1+20%糖耐康含药血清)、TNK中浓度组(TGF-β110μg·L-1+10%糖耐康含药血清)、TNK低浓度组(TGF-β110μg·L-1+5%糖耐康含药血清)。药物干预24 h后,荧光定量PCR检测TGF-β1及其Ⅰ,Ⅱ受体(TβRI,TβRⅡ)的mRNA表达,Western blot检测Smad 2、Smad 3的蛋白表达。结果:HK-2细胞经TGF-β1诱导后,TβRⅠ,TβRⅡ的mRNA表达和Smad 2,Smad 3的蛋白表达显著上升,与空白对照组相比有显著性差异(P<0.05),但经TNK含药血清干预后,其表达逐步下降,与单纯TGF-β1诱导组及TGF-β1+空白血清对照组相比有显著性差异(P<0.05)。而空白血清无此作用。结论:TNK能够调控TGF-β1诱导的人肾小管上皮细胞转分化Smad信号通路,在一定程度上具有抑制肾间质纤维化的作用。
Objective: To explore the effect of Tangnaikang (TNK) on the smads signaling pathway of human renal tubular epithelial cells (HK-2) induced by transforming growth factor-β1 (TGF-β1). Method: The HK-2 cells were cultured by DMEM/F12 (1:1 ) with 10% fetal bovine serum and divided into control group, TGF-β1 group (TGF-β1 10μg ·L^-1), rat serum control group (TGF-β1 10g·L^-1 + 10% rat serum), TNK - containing rat serum therapy groups (TGF-β,10 μg·L^-1 + 20% TNK or + 10% TNK or + 5% TNK). After 24 h, the expression of transforming growth factor ]3 receptor I (TβRI) , transforming growth factor β receptor II (TβRII) mRNA were tested by fluorescence quantitatiye PCR assay, and the expression of Smad 2, Smad 3 protein by Western-blot assay. Result: The expression of TβRI, TβRII mRNA and Smad 2, Smad 3 protein of HK-2 cultured with TGF-β1 were much notable than the control, and significantly decreased in HK-2 cultured with TGF-β1 plus TNK compared with only TGF-β1 (P 〈 0.05) , but only rat serum had no such effect. Conclusion:TNK could regulate the smads signaling pathway of human renal tubular epithelial cells HK-2 induced by transforming growth factor-β1 , and could prevent the development of renal fibrosis to a certain extent.
