Abstract
Acute myeloid leukemia (AML) is an aggressive clonal disorder of hematopoietic stem cells (HSCs) and primitive progenitors that blocks their myeloid differentiation generating self-renewing leukemic stem cells (LSCs). Here we show that the mRNA m6A reader YTHDF2 is overexpressed in a broad spectrum of human AML and is required for disease initiation, as well as propagation in mouse and human AML.
YTHDF2 decreases the half-life of diverse m6A transcripts that contribute to the overall integrity of LSC function, including tumor necrosis factor receptor Tnfrsf2 whose upregulation in Ythdf2-deficient LSCs primes cells for apoptosis. Intriguingly, YTHDF2 is not essential for normal HSC function with YTHDF2-deficiency actually enhancing HSC activity. Thus, we identify YTHDF2 as a unique therapeutic target whose inhibition selectively targets LSCs while promoting HSC expansion.
