Pearson correlation analysis comparing the expression of each marker in normal prostate and in tumor revealed a significant correlation between HOXB13 and PSMA for normal prostate (r = 0.684, P = 0.001) and tumor (r = 0.501, P = 0.028) (Fig. 3C; Supplemental Fig. 4A). The gene discussed is FOLH1; the disease is neoplasm.
