METTL14 and neoplasm: METTL14, an m6A methyltransferase, catalyzes RNA m6A modification by forming a complex with METTL3 and WTAP.25 Recent research demonstrated that piRNA-14633 significantly increases METTL14 mRNA stability, thereby enhancing m6A RNA methylation in CC.26 Furthermore, METTL14 has been implicated in correlating with the infiltration of tumor-associated macrophages and the prognosis of CC.
