摘要
采用实时荧光PCR和激光共聚焦技术研究降压益肾颗粒(JYYS)对自发性高血压大鼠(SHR)肾组织细胞外基质降解系统转化生长因子-β1(TGF-β1)、Ⅳ型胶原蛋白(COLⅣ)、基质金蛋白酶-9(MMP-9)及其抑制物金属蛋白酶组织抑制因子-1(TIMP-1)表达的影响。以JYYS和苯那普利为研究对象,考察不同剂量JYYS和苯那普利对SHR肾脏TGF-β1、COLⅣ、MMP-9及其抑制物TIMP-1 mRNA表达和蛋白表达的差异。结果表明:JYYS长期给药可降低TIMP-1、TGF-β1及COLⅣ转录和蛋白水平,上调肾组织局部MMP-9mRNA和蛋白水平,从而纠正MMP-9/TIMP-1失衡,促进细胞外基质的降解,减少细胞外基质的积聚,产生肾脏保护作用。
This article investigate the effect of the Jiangya Yishen(JYYS) granule on regulative system of extracellular matrix(ECM)decomposition of spontaneously hypertensive rats(SHR),we determined the expression of include transforming growth factor β1(TGF-β1),collagen type IV(COLIV),matrix metalloproteinase-9(MMP-9),tissue inhibitor of metalloproteinase-1(TIMP-1)by utilizing real time fluorescent PCR technique(RT-PCR) and laser confocal fluorescence microscopy.The results showed that JYYS could enhance the level of renal MMP-9 mRNA and its protein level,meanwhile down-regulate the transcription of TIMP-1,TGF-β1,COLIV and decreasing their protein level after long term treatment.Therefore,JYYS corrected the imbalance of MMP-9/TIMP-1,then enhanced the degradation of ECM and decreased the accumulation of ECM to protect kidney in SHR.
