HPN and posterior cortical atrophy: In PCa1 cohort, comparison of PCa to NPT samples, revealed significant up-regulation of HPN (FC 3.3; p < 0.001), ERG (FC 3.0; p = 0.038), and EZH2 (FC 1.3; p = 0.029) in cancerous tissues, while FABP7 (FC 4.4; p < 0.001) was significantly down-regulated (Supplementary Figure 1A).
