CDKN2A and neoplasm: We screened out 21 differentially expressed genes from 67 NRGs and compared their expression in non-tumor and tumor tissues, including 4 downregulated (GATA3, MYCN, IDH2, and BACH2) and 17 upregulated NRGs (TRAF2, LEF1, FAS, TNFRSF1B, EGFR, MYC, TLR3, BNIP3, AXL, CD40, ALK, MLKL, PLK1, ZBP1, FASLG, TERT, and CDKN2A).
