METTL3 and cancer: Other pro-methylating molecules displayed the capability to bind the Methyl Transferase-like 3 (METTL3)/METTL14/Wilm’s Tumor-1-Associated Protein (WTAP) complexes, thus increasing the cellular levels of N6-methyladenosine (m6A), whose deficiency has been involved in several diseases such as cancer, neurodegeneration and aging [11].
