Claudin-4, DAD1, POX1 and TPD52 expression in BPH, PCa and metastatic tissue samples was assessed using quantitative real-time RT–PCR. The transcript ratios (candidate gene transcripts/β2M transcripts; y axis) were plotted against patient samples (BPH, PCa and metastasis; x axis). The expression of each candidate gene was determined in a minimum of 18 BPH, 17 PCa and 5 metastatic tissue samples. Error bars represent s.e. (standard error).
