To screen for potential probone metastasis‐related lncRNAs in PCa, the lncRNA expression profiles from The Cancer Genome Atlas (TCGA) dataset were first analyzed, and the screening rationale is depicted in Fig. 1A. Interestingly, the lncRNA, prostate cancer‐associated transcript 7 (PCAT7), was screened out to be a significant bone metastasis‐related lncRNA in PCa and was selected for further study by virtue of its nomenclature indicating its potentially critical role in PCa. The gene discussed is PCAT7; the disease is posterior cortical atrophy.
