Identification of hub genes. (a) The 39 genes was found to belong to both DEGs and co-expressed genes of METTL1. (b) The protein-protein interaction network analysis for 39 genes was performed using STRING database. (c) The top 5 hub genes were selected using degree algorithm in cytoHubba plugin of Cytoscape. (d–f) The association between the overall survival of BRCA patients and the expression of ANAPC11 (d), NME1 (e), and POP7 (f) were analyzed. BRCA, breast invasive carcinoma.
