METTL14 can positively regulate the primary microRNA 126 process in an m6A‐dependent manner to inhibit the metastatic potential of HCC.12 METTL14, as an important m6A methyltransferase, has been identified as playing an important role in many physiological functions18, 19, 20, 21 and is also related to the occurrence and development of a variety of cancers.12, 22, 23 In addition, METTL14 has become a new target for treatment in EBV‐associated tumors.24 Here, METTL14 is linked to cancer.
