In the Ginos Head-Neck dataset, CXCL1, CXCL2, CXCL3, CXCL5, CXCL6, CXCL8, CXCL9, CXCL10, CXCL11, and CXCL13 were overexpressed in HNSCC samples in contrast with normal tissues, and the fold changes were 17.404, 12.793, 5.374, 16.431, 2.964, 36.405, 6.976, 6.41, 6.635, and 6.901, respectively (19). This evidence concerns the gene CXCL2 and head and neck squamous cell carcinoma.
