瑞舒伐他汀对急性冠脉综合征患者CD4+ T淋巴细胞miRNA表达的影响
目的研究瑞舒伐他汀对急性冠脉综合征(ACS)患者外周血CD4+T淋巴细胞基因中微小RNA(miRNA)表达谱的影响,探讨瑞舒伐他汀钙治疗ACS的机制。方法选取2012年3—7月入住济南军区总医院的9例ACS患者,另以因疑似不典型冠心病症状而行320CT示冠脉病变≤50%的住院患者9例作为正常对照组。利用密度梯度法离心分离ACS患者及对照者的外周血单核细胞,免疫磁珠法进一步分离出CD4+T淋巴细胞。采用miRNA基因芯片技术检测CD4+T淋巴细胞miKNA的表达谱,筛选ACS患者与正常对照组,以及ACS患者用药前后差异表达的miRNA。选取其中差异性最为显著的3个miRNA,采用实时荧光定量聚合...

Summary: | 目的研究瑞舒伐他汀对急性冠脉综合征(ACS)患者外周血CD4+T淋巴细胞基因中微小RNA(miRNA)表达谱的影响,探讨瑞舒伐他汀钙治疗ACS的机制。方法选取2012年3—7月入住济南军区总医院的9例ACS患者,另以因疑似不典型冠心病症状而行320CT示冠脉病变≤50%的住院患者9例作为正常对照组。利用密度梯度法离心分离ACS患者及对照者的外周血单核细胞,免疫磁珠法进一步分离出CD4+T淋巴细胞。采用miRNA基因芯片技术检测CD4+T淋巴细胞miKNA的表达谱,筛选ACS患者与正常对照组,以及ACS患者用药前后差异表达的miRNA。选取其中差异性最为显著的3个miRNA,采用实时荧光定量聚合酶链反应(RT-PCR)对差异表达的miRNA进行验证。结果通过基因芯片共检测基因1900余条,其中有差异的有300余条。与正常对照比较,ACS患者中显著上调的基因有126条,如miRNA-21、miRNA-142、miRNA-20a等,显著下调的基因有202条,如miRNA-4734、miRNA-1182、miRNA1273等。ACS患者服用瑞舒伐他汀钙(20mg,1次/d)10d后,与用药前相比,显著上调的基因有157条,如miRNA.4734、miRNA.1182、miRNA-663b等,显著下调的基因有137条,如miRNA-4789、miRNA-5692c、miRNA-26a等。采用RT-PCR进一步验证,结果与miRNA芯片检测结果一致。结论瑞舒伐他汀钙可能通过调节miRNA-4734、miRNA-1182、miRNA-4789等miRNA的表达从而发挥其对ACS的治疗作用。 |
