PVT1 and urinary bladder carcinoma: As following in Table 1, the up-regulated expression of PVT1 was closely associated with histological grade (P = 0.014), and TNM stage (P< 0.001) in bladder carcinomas, the low expression of miR-194-5p was significantly related to histological grade (P=0.006) and TNM stage (P<0.001).
