摘要 目的分析艾滋病相关性弥漫大B细胞淋巴瘤(HIV-DLBCL)及艾滋病患者淋巴结反应性增生(HIV-RH)的microRNA表达谱,筛选差异表达microRNA,为研究microRNA在HIV-DLBCL发生发展及诊断治疗中的作用提供依据。方法收集筛选6例HIV-DLBCL及4例HIV-RH石蜡包埋组织标本,提取总RNA,进行microRNA芯片杂交,运用SPSS 17.0软件进行统计学分析;利用miRWalk、Targetscan、miRanda软件对两组中存在统计学差异的microRNA进行靶基因预测,并进一步通过Gene Ontology(GO)和Kyoto Encyclopedia of Genes and Genomes(KEGG)数据库分析靶基因功能。结果与HIV-RH组相比,miR-4492、miR-208b-3p、miR-4738-3p、miR-4674在HIV-DLBCL组织中显著上调,miR-4453、miR-363-3p显著下调(表达变化>5倍)。预测6个靶基因可能与HIV-DLBCL的发生发展有关:miR-208b-3p的靶基因CDKN1A、NLK、SMAD4及miR-363-3p的靶基因E2F3、FOXG1、TBX3。结论筛选得到多个HIV-DLBCL中具有深入研究价值的microRNA及其靶基因,为进一步研究差异表达microRNA在HIV-DLBCL发病机制中的作用及其靶基因的生物学效应奠定了基础。
