It could affect CRC cell proliferation, apoptosis, cell cycle, migration, invasion, autophagy, epithelial–mesenchymal transition, angiogenesis, and chemoresistance by regulating multiple signaling pathways, such as PI3K/Akt, NF-κB, MAPK, Wnt/β-catenin, epidermal growth factor receptors, p53, TGF-β, mTOR, Hedgehog, and immunomodulatory signaling pathways. The gene discussed is NFKB1; the disease is colorectal carcinoma.
