PSPC1 and posterior cortical atrophy: We also observed the significant downregulation of genes encoding the primary interacting proteins for these non-coding RNAs, including PSPC1 (fold change −1.5; p = 0.0005), and EZH2 (fold change −1.5; p = 0.0332) in all the PCa lines tested; SFPQ (fold change −1.53; p < 0.0001) and GADD45A (fold change −1.996; p < 0.0001), in DU145 and PC3, respectively.
