目的 基于生物信息学方法探讨特发性肺纤维化(IPF)基因的差异表达,挖掘与IPF相关的关键基因和潜在机制.方法 从美国国家生物技术信息中心基因表达综合数据库下载GSE10667、GSE31934和GSE24206数据集,筛选IPF差异基因,进行蛋白-蛋白相互作用网络和信号通路富集分析,并对差异基因进行基因功能聚类分析,筛选IPF的核心基因、信号通路和相关的微RNA(miRNA).结果 经筛选,共获取IPF差异表达基因107个,CXCL12、ACAN、IGF1、CXCL8、CSF2、ICAM1是IPF发病的核心基因,富集于转化生长因子-β、核转录因子κB、肿瘤坏死因子、白细胞介素-17、Janus激酶/信号转导与转录激活因子、磷脂酰肌醇3-激酶/蛋白质丝氨酸苏氨酸激酶等信号通路上,功能聚类分析获得miR-4465、miR-182-5p、miR-1297、miR-1252-3p等miR与IPF关系密切.结论 IPF发病过程中基因表达存在显著差异,其病理过程涉及多靶点、多通路;可能受到多个miRNA调控;CXCL12、ACAN、IGF1、CXCL8、CSF2、ICAM1可能是IPF发病的关键基因.
Objective To explore the differential expression genes,the core genes and potential mechanisms associated with the pathogenesis of idiopathic pulmonary fibrosis(IPF)based on bioinformatics.Methods The GSE10667,GSE31934 and GSE24206 datasets were downloaded from the Gene Expression Omnibus database of the National Center for Biotechnology Information.The DEGs of IPF were screened,the protein-protein interaction network was constructed,the enrichment anal-ysis and functional cluster analysis were performed in order to screen the core genes,signaling pathways and related mi-croRNAs.Results After screening,a total of 107 DGEs in IPF were obtained,CXCL12,ACAN,IGF1,CXCL8,CSF2,I-CAM 1 were the core genes of IPF which enriched in signaling pathways such as transforming growth factor-β,nuclear transcription factor-κ B,tumor necrosis factor,interleukin-17,Janus kinase/signal transducer and activator of transcription,phosphatidylinositol-3-kinases/protein-serine-threonine kinase.The miR-4465,miR-182-5p,miR-1297,miR-1252-3p and other microRNAs which were closely related to IPF were obtained by functional cluster analysis.Conclusion There are significant differences in gene expression during the pathogenesis of IPF.The pathological process involves multiple targets and pathways.IPF pathogenesis may be regulated by multiple microRNAs.CXCL12,ACAN,IGF1,CXCL8,CSF2,ICAM1 may be the core genes in the pathogenesis of IPF.
