Basal mRNA expression for CCL2 (Fig 2A, left panel) and CXCL12 (Fig 2A, right panel) was lower in each of the prostate cancer cell lines relative to the expression detected in the WPMY-1 prostate stromal fibroblast or the monocytic THP-1 cell lines. The gene discussed is CCL2; the disease is Familial prostate cancer.
