CCL18 mRNA and protein expression in prostate cancer (PCa) and adjacent benign prostate tissues detected by real-time quantitative RT-PCR assay (b) and western blot analysis ((a) and (c)). The statistical analysis showed that CCL18 mRNA average expression level (n = 10) was significantly upregulated in PCa tissues compared with those in noncancerous prostate tissues (n = 10, P < 0.001, (b)), which was consistent with the findings of western blot analysis on CCL18 protein expression (n = 10, PCa: 1.12 ± 0.24 versus benign: 0.26 ± 0.16, P = 0.017, (a) and (c)).
