Abstract:

In this study, GSE83514 data set was downloaded from Gene Expression Omnibus (GEO) database, and Weighted Gene Co-Expression Network Analysis (WGCNA) was used to explore the related modules and hub genes of bovine foot-and-mouth disease virus (FMDV) infection. The results showed that through constructing WGCNA co-expression network, the genes of Darkred module and Green module were found to be negatively and positively related to bovine FMDV infection respectively. MFSD4 and RHOH were the hub gene of Darkred module and Green module, respectively. Twenty Gene Ontology (GO) terms and 14 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were enriched in those two modules. DNA replication signaling pathway was the only pathway enriched in both modules. The results of this study provided a bioinformatics basis for investigating the molecular mechanism of bovine FMDV infection, and the selected hub genes, MFSD4 and RHOH, were expected to be therapeutic biomarker for inhibiting the infection of FMDV.
