Then, we confirmed ZFAS1 expression in bladder cancer tissue, normal bladder tissue, human bladder cancer cell line, and normal uroepithelium cell line, and found levels of ZFAS1 expression were elevated in bladder cancer tissues and cell lines compared with normal bladder tissues and normal uroepithelium cell line, respectively. Here, ZFAS1 is linked to urinary bladder carcinoma.
