Based on these two signaling pathways, 13 differentially expressed genes (Vcam1, Atf6b, Akt1, Irf1, Map2k3, Lcn2, Hsp90ab1, Anapc5, Traf4, Fosl1, Jun, Cxcl5, Nfκbia) among NC, CRC, and FP groups were screened and verified by Western blot. The gene discussed is JUN; the disease is colorectal carcinoma.
