METTL14 and urinary bladder cancer: We found that a low expression of METTL14 (a m6A methyltransferase), SMPD4, and SGK2, but a high expression of ALKBH5 (a m6A de methyltransferase), LINC00482, and HIPK3, showed a tendency to associate with worse overall survival in bladder cancer patients (Figures 6C–H).
