The highly DEGs were primarily concentrated in the cytokine–cytokine receptor interaction, pathways in cancer, PI3K‐Akt signaling pathway, Epstein–Barr virus infection, phagosome, human T‐cell leukemia virus 1 infection, cell adhesion molecules, and chemokine signaling pathway, according to the KEGG pathway analysis. This evidence concerns the gene PIK3CG and cancer.
