Objective To identify the potential biomarkers in prostate cancer by bioinformatic analysis.Methods After the gene expression profile GSE55945 was downloaded from GEO database,differentially expressed genes(DEGs)were identified with R Software.The hub genes were screened and validated by bioinformatic methods.Results A total of 462 DEGs were identified,including 114 up-regulated and348 down-regulated ones.GO enrichment analysis revealed that the DEGs were mainly involved in muscle system process,regulation ...
