Abstract
Leukemia-initiating cells can originate from hematopoietic progenitor cells that have acquired self-renewal capacity upon transformation with leukemic fusion genes. In this issue of Cancer Cell, Kirstetter and colleagues describe a mouse model for the frequent CEBPA mutations in human acute myeloid leukemia that result in the synthesis of only the 30kDa isoform, but not the 42kDa isoform of C/EBPalpha. This mutation uncouples C/EBPalpha's roles in myeloid differentiation and proliferation control. Furthermore, this mutation activates self-renewal in committed myeloid progenitor cells and induces myeloid malignancy with complete penetrance that is sustained by leukemia-initiating cells with a committed myeloid molecular signature.
