Consistently, the positive correlation of PCAT7 with TGFBR1 and p‐SMAD3, and the negative correlation of PCAT7 with miR‐324‐5p were further clinically verified in primary PCa cells reported in our previous study (Ren et al., 2019) (Fig. 8E). The gene discussed is PCAT7; the disease is posterior cortical atrophy.
