NFKB1 and nasopharyngeal carcinoma: Besides NF-κB and PI3K, upregulated gene expression in epithelial-mesenchymal transition, Notch and Wnt signaling pathways in EBV+ve cohorts was also revealed by GSEA (Supplementary Fig. 21b–d), indicating enhanced gene expression in these pathways might play functional roles in NPC carcinogenesis.
