基于WGCNA的尿道下裂相关基因鉴定分析OA
Analysis of key gene related to hypospadias based on gene co-expression weight network analysis
目的 利用基因共表达权重网络(weighted gene co-expression network analysis,WGCNA)探索与尿道下裂发病相关的潜在基因.方法 利用WGCNA算法将数据集GSE35034 处理并构建基因共表达权重网络,筛选出与尿道下裂相关性最高的模块,通过基因本体论(gene ontology,GO)、京都基因和基因组百科全书(Kyoto Encyclopedia of Genes and Genomes,KEGG)对模块中的基因进行富集分析.同时进行差异分析,筛选差异基因.将差异基因导入String数据库,利用Cytoscape软件,找出网络中枢纽基因.将以上 3 种方法的结果系统分析,筛选出交集中的核心基因.利用外部数据集对核心基因进行mRNA表达变化及受试者操作特征(receiver operating characteristic,ROC)曲线诊断验证.结果 基于WGCNA方法得到 15 个共表达模块.通过差异分析获得了 93 个满足条件的共同差异基因.通过Cytoscape软件分析最终得到 10 个核心基因.最后 3 种方法得到 2 个交集基因:FBXL16、SYNDIG1.ROC曲线验证了交集基因在尿道下裂患者与正常人中表达存在差异.结论 本研究通过WGCNA获得了 2 个与尿道下裂具有显著相关性的关键基因,可用于尿道下裂发病及治疗的探索.
Objective To explore potential genes associated with the pathogenesis of hypospadias using weighted Gene co-expression network analysis(WGCNA).Methods The WGCNA algorithm was used to process the hypospadias-related dataset GSE35034,and then a gene co-expression weight network was constructed to screen the modules with the highest correlation with hypospadias,and the genes in the modules were enriched and detected by gene ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG).Differential analysis was also performed to screen out differential genes.The differential genes were imported into the String database.Using Cytoscape software,the hub genes in the network were identified.The results screened by the above three methods were combined and analyzed,and the core genes in the intersection set were screened.Using the external dataset GSE121712,the core genes were verified by mRNA expression changes and subject work characterization receiver operating characteristic(ROC)curve diagnosis.Results Fifteen co-expression modules were obtained based on the WGCNA method.Ninety-three common differential genes meeting the conditions were obtained by differential analysis.Ten core genes were finally obtained by Cytoscape software analysis.Finally MEbrown module,differential genes and the 10 core genes yielded a total of 2 intersecting genes:FBXL16 and SYNDIG1.ROC curves verified that the intersecting genes were differentially expressed in patients with hypospadias versus normal subjects.Conclusion In this study,two key genes with significant correlation with hypospadias were obtained by WGCNA,which may be used for the early diagnosis and treatment of hypospadias after further study.
