Colons from p47phox−/− mice with DSS colitis were notable for significantly increased expression of granulocyte-colony stimulating factor (G-csf), chemokine (C-C motif) ligand 3 (Ccl3), and chemokine (C-X-C motif) ligand 2 (Cxcl2) compared to controls. This evidence concerns the gene CXCL2 and colitis.
