Mutant ASXL1 Cooperates with MECOM and BRD4 to Drive Transcriptional Dysregulation in Human Hematopoiesis.
Mutations in the epigenetic regulator ASXL1 are common in myeloid malignancies and portend a near-universally poor prognosis. While multiple mechanisms for mutant ASXL1-dependent oncogenesis have been proposed, none have been functionally validated in the context of the human hematopoietic stem cell, where these mutati...
