Cancer A Pathway to Leukemia

Paula A. Kiberstis

Science, AAAS, Washington, DC 20005, USA

Leukemia is initiated and maintained by a small number of self-renewing cells called leukemia stem cells (LSCs), which share properties with hematopoietic stem cells (HSCs), the self-renewing cells that produce healthy blood cells. Wang et al. studied mouse models of acute myelogenous leukemia (AML), a disease that is often refractory to existing therapies. Activation of the Wnt/β-catenin signaling pathway was required for efficient oncogene-mediated conversion of HSCs into LSCs. This pathway is among the most well studied signaling pathways in cell biology, setting the stage for testing of β-catenin signaling antagonists in preclinical models of AML.
