目的:应用基因芯片技术研究心房颤动(房颤)患者心房组织中miRNA的表达谱,分析差异表达的miRNA,为进一步研究miRNA在房颤发生、发展中的作用奠定基础.方法:采用miRNA基因芯片技术检测房颤患者和非房颤患者心房组织样本中miRNA的表达水平;采用实时定量PCR(quantitative real-time PCR,qRT-PCR)对部分差异表达的miRNA进行验证.结果:MiRNA基因芯片分析结果显示,与非房颤组织相比,房颤组织中差异表达的miRNA共有26个,其中16个miRNA表达上调,10个miRNA表达下调.qRT-PCR验证结果与芯片结果相一致.结论:MiRNA在房颤患者心房组织中存在差异性表达.

Objective： To analyze the differentially expressed microRNAs （miRNA） in atrial tissues from patients with atrial fibrillation by gene chip technology and to lay a foundation for studing its role in the development of atrial fibrillation. Methods： The miRNA gene chip was used to detect the miRNA expression level in patients with atrial fibrillation and without atrial fibrillation. Quantitative real-time PCR （qRT-PCR） was used to verifythe differential expression of microRNAs.Results： q-he results of miRNA gene chip showed that there were ...
