The Yin and Yang of RNA Methylation: An Imbalance of Erasers Enhances Sensitivity to FTO Demethylase Small-Molecule Targeting in Leukemia Stem Cells

A prevalent eukaryotic N6-methyladensosine (m6A) post-transcriptional mark can be "erased" by the m6A demethylase FTO, which is commonly deregulated in acute myeloid leukemia (AML). In this issue of Cancer Cell, Huang et al. design small-molecule FTO inhibitors, FB23 and FB23-2, and demonstrate their potent inhibitory impact in AML models.
