METTL14 and urinary bladder carcinoma: METTL14 exerts a tumor‐suppressive function in bladder cancer and hepatocellular cancer but promotes cancer progression and metastasis in pancreatic cancer.[26, 40, 41] These seemingly contradictory results indicate the complexity of the role of m6A in tumor progression and highlight that METTL14 is rarely studied in EC and deserves further exploration.
