Severe Acute Respiratory Syndrome Coronavirus Type 2 (SARS-CoV-2) is an enveloped single-stranded RNA virus that can lead to respiratory symptoms and damage many organs such as heart, kidney, intestine, brain and liver. It has not been clearly documented whether myocardial injury is caused by direct infection of cardiomyocytes, lung injury, or other unknown mechanisms. The gene expression profile of GSE150392 was obtained from the Gene Expression Omnibus (GEO) database. The processing of high-throughput sequencing data and the screening of differentially expressed genes (DEGs) were implemented by R software. The R software was employed to analyze the Gene Ontology (GO) analysis and the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. The protein-protein interaction (PPI) network of the DEGs was constructed by the STRING website. The Cytoscape software was applied for the visualization of PPI network and the identification of hub genes. The statistical analysis was performed by the GraphPad Prism software to verify the hub genes. A total of 516 up-regulated genes and 191 down-regulated genes were screened out. The top 1 enrichment items of GO in biological process (BP), Cellular Component (CC), and Molecular Function (MF) were type I interferon signaling pathway, sarcomere, and receptor ligand activity, respectively. The top 10 enrichment pathways, including TNF signaling pathway, were identified by KEGG enrichment analysis. A PPI network was established, consisting of 613 nodes and 3,993 edges. The 12 hub genes were confirmed as statistically significant, which was verified by GSE151879 dataset. In conclusion, the hub genes of human iPSC-cardiomyocytes infected with SARS-CoV-2 were identified through bioinformatics analysis, which may be used as biomarkers for further research.
严重急性呼吸系统综合症冠状病毒 2 型(SARS-CoV-2)是一种包膜的单链 RNA 病毒,可导致呼吸道症状,并损害心、肾、肠、脑和肝等多种器官。目前尚不清楚心肌损伤是由心肌细胞直接感染、肺部损伤还是其他未知机制引起的。从基因表达综合数据库(GEO)中获得了 GSE150392 的基因表达谱。使用 R 软件对高通量测序数据进行处理,并筛选差异表达基因(DEGs)。使用 R 软件对基因本体论(GO)分析和京都基因与基因组百科全书(KEGG)分析进行分析。使用 STRING 网站构建 DEGs 的蛋白质-蛋白质相互作用(PPI)网络。使用 Cytoscape 软件对 PPI 网络进行可视化,并识别枢纽基因。使用 GraphPad Prism 软件进行统计分析,以验证枢纽基因。筛选出 516 个上调基因和 191 个下调基因。GO 在生物学过程(BP)、细胞成分(CC)和分子功能(MF)中的前 1 个富集项分别为 I 型干扰素信号通路、肌节和受体配体活性。KEGG 富集分析确定了前 10 个富集途径,包括 TNF 信号通路。建立了一个 PPI 网络,包含 613 个节点和 3993 个边。通过 GSE151879 数据集验证,确定了 12 个枢纽基因具有统计学意义。通过生物信息学分析鉴定了感染 SARS-CoV-2 的人诱导多能干细胞心肌细胞的枢纽基因,这些基因可能作为进一步研究的生物标志物。
