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. This evidence concerns the gene METTL14 and cancer.
