ADAR1 Activation Drives Leukemia Stem Cell Self-Renewal by Impairing Let-7 Biogenesis

Bhaskar Chanda Stem Cell Zipeto, Court, and colleagues show a pivotal role for let-7 microRNA editing in leukemia stem cell self-renewal. Impairment of let-7 is dependent on JAK2 and BCR-ABL-mediated activation of ADAR1 editing. This provides a novel mechanism of malignant reprogramming that can be targeted through combined JAK2 and BCR-ABL or ADAR1 inhibition.
