PU.1 and Junb: suppressing the formation of acute myeloid leukemia stem cells.
Cancer Cell. 2006; (6): 456-7
Improved understanding of the molecular pathways that suppress the genesis and maintenance of cancer stem cells will facilitate development of rationally targeted therapies. PU.1 is a transcription factor that is required for normal myelomonocytic differentiation in hematopoiesis, and reduced PU.1 activity has been associated with myeloid leukemogenesis in man and in mouse models. A recent study by Steidl et al. demonstrates that Junb and Jun, two AP-1 transcription factors, are critical downstream effectors of the tumor suppressor activity of PU.1, and that reduced expression of Junb, in particular, may be a common feature of acute myeloid leukemogenesis.
