The RNA methyltransferase METTL3 catalyzes N6-methyladenosine (m6A) modification of messenger RNAs (mRNAs). It is overexpressed in many types of cancer, including acute myelogenous leukemia (AML), and promotes cancer cell growth and tumorigenicity. Now, a selective small molecule inhibitor of METTL3 shows significant antileukemic effects in preclinical AML models, highlighting the promise of pharmacological METTL3 inhibition as a new cancer therapy.
