摘要: 目的 筛选新疆地区维吾尔族人群原发性高血压(EH)患者与健康者血浆中microRNA差异表达谱,为进一步探究microRNA与新疆维吾尔族人群原发性高血压的发病的关系提供依据。方法 选取4例维吾尔族原发性高血压患者和4名维吾尔族健康人的全血,用Agilent Human miRNA芯片检测血浆microRNA表达谱。对差异表达的microRNA进行聚类分析、靶基因预测、靶基因注释等生物信息学分析。另外选取独立验证样本(15例维吾尔族原发性高血压患者及15名维吾尔族健康人),对差异表达的microRNA进行qPCR验证。结果 实验组与对照组相比,筛选获得 257个差异表达microRNA,其中161个上调表达,97下调表达。通过TargetScan、PITA、microRNAorg数据库对差异表达microRNA进行靶基因预测,对3个数据库预测到的靶基因取交集,获得6580个microRNA调控的靶基因系。最终筛选得到表达上调最多和下调最多的两个microRNA,hsa-miR-1183和 hsa-miR-30e-5p。结论 原发性高血压患者有着独特的microRNA表达谱,筛选获得的差异表达microRNA,可能是原发性高血压早期诊断的生物标志物和潜在的治疗靶点,同时对于后续研究原发性高血压的发病机制具有提示作用。

Abstract: Objective The aim of this study was to screen the microRNA expression file in Uighur population, which would supply research data for further exploring the relationship of microRNA and molecular mechanism of hypertension. Methods Whole blood samples were taken from 4 hypertension patients and 4 health people from Uighur population. MicroRNA expression profile was tested by using Agilent Human miRNA array. Clustering analysis and target gene annotation were performed on differentially expressed microRNAs. Another 30subjects were sampled independently (15 from hypertension patients and 15 from healthy people) andthe differentially expressed microRNAs were validated by quantitative PCR. Results Compared microRNA profiles of the two groups, 257 differentially expressed microRNAs were filtered, in which 161 were up-regulated and 97 were down-regulated. Target genes were predicted in three database, that is, TargetScan, PITA and microRNAorg. 6’580 target genes were obtained by computing the intersection of three databases.Hsa-miR-1183 was the most up-regulated and hsa-miR-30e-5p was the most down-regulated microRNA in hypertension patients. Conclusions microRNA expression profile of Experimentalgroup was different from the control group. Differentially expressed microRNAs would be potential biomarkers for diagnosis or therapy. This study supplied a foundation for exploring the mechanism of essential hypertension.
