PVT1 and urinary bladder cancer: Table 1 shows that three of the first five predicted lncRNAs have found supporting evidence in the 2017 version of the lncRNADisease database. MEG3 and PVT1 have not been verified by the lncRNADisease database, but we have manually excavated recent biomedical literature and find them and bladder cancer-related evidence. For example, Fan et al. (2020) found that MEG3 can control the progression of bladder cancer through PI3K/AKT/mTOR pathway regulation. Tian et al. (2019) found that PVT1 can regulate the growth, migration, and invasion of bladder cancer through mir31/CDK1.
