To identify bone metastasis‐relevant oncogenic lncRNAs, the lncRNA expression profiles of PCa dataset from TCGA were analyzed and found that PCAT7, a prostate cancer‐associated lncRNA by virtue of its nomenclature, was significantly upregulated in bone metastasis‐positive PCa tissues, further validated in our PCa samples. The gene discussed is PCAT7; the disease is prostate cancer.
