For example, the directional migration of A2056 human melanoma cells was shown by exposure of the C-X-C-type chemokine ligand (CXCL) 8 [8], and both CXCL8 and CXCL5 expression in non-small cell lung carcinoma (NSCLC) has been correlated with tumor angiogenesis [9]. This evidence concerns the gene CXCL8 and non-small cell lung carcinoma.
