PTGS2 and neoplasm: The 35 upregulated genes included NF-κB genes (NFKB1, RELA, IKBKG, NFKBIB, NFKB2, REL, CHUK) and NF-κB-regulated genes involved in apoptosis (MCL1L, TNFAIP3/A20, GADD45B, FASLG, MCL1S, IER3L, TNFRSF10B/TRAILR2), immune response (CD40, CD48, TNFSF11/RANKL, TNFRSF11A/RANK, CCL2/MCP-1, CD40LG, IL15, GBP1), proliferation (CCND2, CCND3, CSF1R, CSF1, SOD2), tumor progression (CXCL12, SELE, TNC, VCAM1, ICAM1, PLAU/UPA) or angiogenesis (PTGS2/COX2, CXCL1/GRO1).
