摘要: 目的

通过生物信息学工具筛选子宫内膜异位症(EMS)相关的差异表达基因(DEGs),为阐明EMS的病因提供理论依据,为EMS的诊断和治疗开辟新的研究方向。

方法

从基因表达汇编(GEO)数据库检索“endmetriosis”,下载涉及EMS组织和正常子宫内膜组织的高通量芯片数据集GSE25628,GSE23339和GSE7305。使用GE02R在线分析工具筛选EMS组织和正常子宫内膜组织的DEGs,使用基因本体功能注释(GO)和京都基因与基因组百科全书(KEGG)对DEGs进行功能及通路富集分析,利用STRING数据库建立蛋白-蛋白互作(PPI)网络,最后通过Cytoscape软件对PPI网络进行可视化并筛选核心基因。

结果

分析确定了27个上调DEGs和43个下调DEGs。GO富集分析,DEGs主要富集于细胞外基质、细胞外空间和细胞外区域等方面;KEGG通路分析,DEGs主要富集于磷酸肌醇代谢信号通路。通过 STRING 数据库和Cytoscape 软件共筛选出核心蛋白聚糖(DCN)、上皮细胞黏附分子(EPCAM)、双链蛋白聚糖(BGN)、脂肪酸结合蛋白4(FABP4)、神经酪氨酸激酶受体2(NTRK2)、磷脂酰肌醇聚糖3(GPC-3)、表皮生长因子受体3(ERBB3)、分化抗原簇蛋白24(CD24)、巢蛋白2(NID2)和血小板反应蛋白2(THBS2)连接度最高的前10个核心基因,其中DCN、BGN、NID2和THBS2 4种基因与细胞外基质的生物学功能有密切关联。

结论

细胞外基质相关基因失调可能在EMS发生发展过程中起重要作用,且细胞外基质相关基因可能成为EMS早期诊断的生物标志物及治疗靶点。

Abstract: Objective

To screen the differentially expressed genes (DEGs) of endometriosis (EMS) by bioinformatics tools,and to provide theoretical basis for clarifyinng the pathogenesis of EMS, and to find a new research direction for the diagnosis and treatment of EMS.

Methods

The datasets (GSE25628, GSE23339 and GSE7305) including EMS tissue and normal endometrial tisue were downloaded from the Gene Expression Omnibus(GEO) database by searching for endometriosis. The GE02R online analvsis tools were used to screen for the DEGs in the EMS tissue and the normal endometrial tissue. Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) were used to analyze the function and pathway enrichment of DEGs, the STRING database was used to establish the protein-protein interaction (PPI) network. Finally,the PPI network was analyzed and visualized by Cytoscape software, and the top ten core genes were screened.

Results

After the DEGs analysis, a total of 27 up-regulated DEGs and 43 down-regulated DEGs were identified. The GO enrichment analysis results showed that DEGs were mainly enriched in the extracellular matrix, extracellular space, extracellular region and so on. The results of KEGG pathway analysis demonstrated that DEGs were mainly enriched in phosphate inositol metabolic signal pathway.Through STRING and Cytoscape softwares, the top 10 core genes with the highest connectivities in the PPI network were screened out, including DCN, EPCAM, BGN, FABP4, NTRK2, GPC-3, ERBB3, CD24, NID2, and THBS2. Among them, DCN, BGN, NID2, and THBS2 were associated with the biological function of extracellular matrix.

Conclusion

The disorder of extracellular matrix-related genes may play an important role in the occurrence and development of EMS, and the extracellular matrix-related genes may become the biomarkers and for early diagnosis and therapeutic targets of EMS.
