    Abstract

    Identification of Gene Targets of Mutant C/EBPα Reveals a Critical Role for MSI2 in CEBPA-Mutated AML

    Integrative analysis identified 117 p30-dependent regulatory elements associated with 33 strongly down-regulated genes upon p30-knockdown. CRISPR/Cas9-mediated mutational disruption of these genes revealed the RNA-binding protein MSI2 as a critical p30-target.
