也页目的:积雪草颗粒对TGF-β1诱导的体外培养的肾小管上皮细胞MMP-2、TIMP-2 mRNA及蛋白表达的影响。方法:将体外培养的大鼠近端肾小管上皮细胞(NRK52E)随机分为6组:正常对照组(DZ组)、TGF-β1诱导组(T组)、积雪草小( JX组)、中( JZ组)、大剂量( JD组)组及蒙诺组( M组)。培养48 h后取出,应用实时荧光定量PCR( RTFQ PCR)技术和western-blot技术检测细胞MMP-2、TIMP-2的mRNA及蛋白表达。结果:与DZ相比,T、JX、JZ、JD、M组细胞MMP-2、TIMP-2的mRNA及蛋白表达明显升高(P<0.05);JX、JZ、JD、M组细胞MMP-2、TIMP-2的mRNA及蛋白与T组相比明显下降(P<0.05),M组细胞变化与JD组相似(P>0.05)。结论:积雪草抗TIF作用可能通过抑制MMP-2、TIMP-2的高表达,调节MMP-2/TIMP-2的平衡而实现,且与其剂量呈正相关。

Objective:We investigated Centella asiatica particles on TGF-β1 -ind-uced in vitro cultured tubular pithelial cells of the mRNA and protein of MMP-2,TIMP-2 expression. Methods:Rat proximal tubular epithelial cells (NRK52E) cultured in vitro were randomly divided into 6 groups:Normal control group(group N),TGF-β1 -induced (10 ng/ml) group(group T),low ( group JX) , medium ( group JZ ) , hi - gh ( group JD ) Centella asiatica group, Monopril group ( group M ) . Take these cells after 48 hours,and application of realtime fluorescence quantitative PCR(RTFQ PCR) to detect the mRNA of MMP-2and TIMP-2,appli-cation of western-blot detect their protein. Results:Compared with the group DZ,the expression of MMP-2,TIMP-2 mRNA and protein in group T,JX,JZ,JD and M was significantly increased (P<0. 05). Compared with group T,the expression of MMP-2, TIMP-2 mRNA in group JX,JZ,JD and M decreased significantly (P<0. 05 ). The change of group M is similar with group JD(P>0. 05). Conclusion:The centella asiatica in the role of anti-TIF may be provided by inhibiting the expression of MMP-2,TIMP-2 and adjusting the balance of MMP-2/TIMP-2,and positively correlated with their dose.
