The role of m6A RNA methyltransferase METTL3 in drug resistance mechanisms in acute myeloid leukemia. (PubMed, Blood Res)
Inhibitors such as STM2457, METTL3-directed PROTACs, and rational drug combinations with agents including venetoclax, anthracyclines, and ATRA, have reversed resistance phenotypes and impaired leukemic cell fitness...By integrating molecular, cellular, and microenvironmental evidence, this review underscores METTL3 as a central driver of drug resistance and a promising therapeutic target in relapsed or refractory AML. Unlike previous summaries, it highlights the convergence of METTL3-mediated m6A modifications with noncoding RNA regulation, autophagy, and niche adaptation, and critically evaluates emerging therapeutic approaches, including catalytic inhibitors, PROTACs, and natural compounds.
