In order further test the possible interaction between CXCR4 receptor and CCL20 chemokine in prostate cancer, we evaluated the coexpression of CCL20 and CXCR4 in human prostate cancer tissues with the use of commercially available additional array of 48 paraffin-embedded prostate sections from patients with advanced prostate cancer. This evidence concerns the gene CXCR4 and prostate carcinoma.
