NFKB1 and neoplasm: KEGG pathway analysis was conducted for the top 50 significant genes of each group, respectively (Figures 4D, E), and indicated that tumor proliferation and immune-related pathways were enriched in the positively correlated group, such as the NF-kB signaling pathway, the Jak-STAT signaling pathway, the natural killer cell mediated cytotoxicity, and the T cell receptor signaling pathway.
