PCAT6 and urinary bladder carcinoma: For example, the expression of lncRNAs such as TUC338 and PVT1 can be used as biomarkers for early diagnosis of bladder cancer [28, 29], while the expression of PCAT6, NRON, GAS6-AS2, SNHG3, lncRNA TP73-AS1, and LINC00641 can predict poor prognosis of bladder cancer [30–35].
