Abstract
Protein-coding and noncoding RNAs can be decorated with a wealth of chemical modifications, and such modifications coordinately orchestrate gene expression during normal hematopoietic differentiation and development. Aberrant expression and/or dysfunction of the relevant RNA modification modulators/regulators ("writers," "erasers," and "readers") drive the initiation and progression of hematopoietic malignancies; targeting these dysregulated modulators holds potent therapeutic potential for the treatment of hematopoietic malignancies. In this review, we summarize current progress in the understanding of the biological functions and underlying mechanisms of RNA modifications in normal and malignant hematopoiesis, with a focus on the N6-methyladenosine modification, as well as discuss the therapeutic potential of targeting RNA modifications for the treatment of hematopoietic malignancies, especially acute myeloid leukemia.
