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). Here, PLK1 is linked to neoplasm.
