PCAT7 and posterior cortical atrophy: In this study, we identified a PCa‐associated lncRNA, prostate cancer‐associated transcript 7 (PCAT7), also known as PCAN‐R2, which locates in chromosome (chr) 9q22.32 and has been reported to be involved in tumor progression (Liu et al., 2017b; Liu et al., 2017a).
