FOLH1 and neoplasm: This trend was maintained between AR and HOXB13, although slightly reduced in tumor (normal prostate: r = 0.804, P = <0.0001; tumor: r = 0.598, P = 0.006), and between PSMA and AR (normal prostate: r = 0.878, P < 0.0001; tumor: r = 0.458, P = 0.048) (Fig. 3C; Supplemental Figs. 4B and 4C).
