METTL3 and urinary bladder carcinoma: Similarly, in our previous study, we also found that the expression of METTL3 and YTHDF2 was up‐regulated in bladder cancer and showed that METTL3 inhibited the expression of SETD7 and KLF4 in an m6A‐YTHDF2‐dependent manner to further promote the proliferation and metastasis of bladder cancer.32
