Summary:背景与目的长非编码RNA（long non-coding RNA,lnc RNA）在肿瘤的发生、侵袭转移等过程中发挥着重要的调控作用。本研究通过实验和生物信息学手段系统性研究lnc RNA MALAT1调控的微小RNA（micro RNA,miRNA）。方法设计特异性敲减MALAT1的反义寡核苷酸（antisense oligonucleotides,ASO）,在A549细胞中敲减MALAT1,通过Tqa Man Low Density Array（TLDA）芯片研究敲减MALAT1后miRNA表达变化;使用基因集富集分析（gene set enrichment analysis,GSEA）方法分析敲减MALAT1之后差异表达基因,寻找富集的miRNA。结果 ASO有效降低了MALAT1表达,敲减MALAT1之后153个miRNA表达显著变化,其中131个miRNA表达上调,22个miRNA表达下调。在A549细胞中敲减MALAT1后,458个基因发生显著差异表达,GSEA分析发现多个miRNA在差异表达基因中被显著富集。对TLDA和GSEA数据取交集并进一步分析确认28个被MALAT1调控的miRNA。结论本研究系统鉴定了MALAT1对miRNA的调控,为进一步研究提供了基础。

Background and objective Long non-coding RNA （lncRNA） plays important regulatory roles in the development and invasion of various cancers. The aim of current study is to comprehensively identify microRNAs （miRNA） regulated by lncRNA MALAT 1 via experimental and bioinformatics methods. Methods Antisense oligonucleotides （ASO） specifically targeting MALAT1 were designed and synthesized. After knockdown of MALAT1 by ASO in A549 ceils, miRNA expression changes were profiled by TqaMan L
