Several chemokine ligands (chemokine (C-C motif) ligand 3 (CCL3), chemokine (C-X-C motif) ligand 2 (CXCL2), and chemokine (C-X-C motif) ligand 3 (CXCL3)) also demonstrated >25-fold overexpression in 4-NQO-induced oral cancers. This evidence concerns the gene CXCL2 and lip and oral cavity carcinoma.
