养肝益水颗粒对自发性高血压大鼠肾小球足细胞TGF-β1、p27蛋白及其基因表达的影响

         

摘要

目的 从足细胞途径探讨养肝益水颗粒改善高血压肾损害的作用机制.方法 将64只自发性高血压大鼠随机分4组,每组16只,即养肝益水颗粒高、低剂量治疗组,贝那普利组,模型组,并选取16只WKY大鼠作为正常组.检测实验前后各组大鼠的血清肌酐(serum creatinine, SCr)、血尿素氮(blood urea nitrogen, BUN)水平;采用RT-qPCR检测大鼠肾皮质转化生长因子(transforming growth factor beta 1,TGF-β1)、p27 mRNA表达水平;Western blot检测大鼠肾皮质TGF-β1、p27蛋白表达变化.结果 治疗前后各组自发性高血压大鼠SCr、BUN水平显著高于正常组(P<0.05);治疗后,养肝益水颗粒高、低剂量组,西药组大鼠SCr、BUN水平均显著降低(P<0.05),但3组之间比较,差异无统计学意义(P>0.05).模型组肾皮质p27蛋白、p27 mRNA及TGF-β1 mRNA、TGF-β1蛋白表达水平均明显高于正常组(P<0.05);治疗后,养肝益水颗粒高、低剂量组相比,高剂量组肾皮质p27蛋白及p27 mRNA表达水平均降低(P<0.05);肾皮质TGF-β1 mRNA、TGF-β1蛋白相对表达水平显著降低(P<0.05).结论 养肝益水颗粒通过下调TGF-β1、p27的表达,调节足细胞的增殖和凋亡,维持足细胞正常形态和结构,从而达到保护肾脏的目的.%Objective To investigate the mechanism of action of Yanggan Yishui Granule in improving hypertensive kidney injury via podocytes.Methods A total of 64 spontaneously hypertensive rats were randomly divided into high-and low-dose Yanggan Yishui Granule groups, benazepril group, and model group, with 16 rats in each group;another 16 WKY rats were selected as normal group.The levels of serum creatinine (SCr) and blood urea nitrogen (BUN) were measured before and after the experiment, and RT-qPCR and Western blot were used to measure the mRNA and protein expression of transforming growth factor-β1 (TGF-β1) and p27 in the renal cortex in rats.Results The spontaneously hypertensive rats had significantly higher levels of SCr and BUN than the normal rats before and after treatment (P<0.05).After treatment, the high-and low-dose Yanggan Yishui Granule groups and the benazepril group had significant reductions in the levels of SCr and BUN (P<0.05), but there were no significant differences between the three groups (P>0.05).The model group had significantly higher mRNA and protein expression of p27 and TGF-β1 in the renal cortex than the normal group (P<0.05).After treatment, compared with the low-dose Yanggan Yishui Granule group, the high-dose Yanggan Yishui Granule group had significant reductions in the mRNA and protein expression of p27 and TGF-β1 (P<0.05).Conclusion Yanggan Yishui Granule can protect the kidney through down-regulating the expression of p27 and TGF-β1, regulating the proliferation and apoptosis of podocytes, and maintaining the normal morphology and structure of podocytes.
