摘要 目的设计针对纤溶酶原激活物抑制物(plasminogen activator inhibitor,PAI)基因的小干扰RNA(PAI siRNA),研究其对PAI和组织型纤溶酶原激活物(tPA)表达的影响。方法体外化学合成PAI siRNA,电转染法转染人主动脉平滑肌细胞(HASMC),采用RT-PCR及Western印迹法分别从mRNA和蛋白水平上检测转染细胞PAI及tPA蛋白的表达情况。结果转染细胞PAI mRNA和蛋白表达水平均较对照组明显下降(P<0.01),tPA蛋白表达较对照组明显升高(P<0.01)。结论PAI siRNA可快速特异性封闭PAI基因表达,并调节tPA蛋白表达,使其升高,为进一步研究PAI在血栓性疾病中作用机制以及探讨PAI与tPA之间关系提供了实验基础。
