The association of these two factors with cancer metastasis could be corroborated in the LEC-prostate cancer model, where we found a strong up-regulation of CCL7 and CXCL6 in LECs after interaction with the metastatic cell line LNCAP, but not after co-culture with the non-metastatic cell line DU145. The gene discussed is CXCL6; the disease is cancer.
