PCAT1 and posterior cortical atrophy: Since PCA3 discovery and the development of RNA-seq technologies, the PCa transcriptome has been extensively explored by The Cancer Genome Atlas (TCGA) consortium and others to identify numerous PCa-associated lncRNAs (PCAT family) such as PCAT1, PCAT7, or PCAT114/SChLAP1 (Prensner et al, 2014; Iyer et al, 2015).
