The core-binding factor leukemias: lessons learned from murine models.

Abstract

The recent development of murine models of core-binding factor leukemias has provided important insights into the underlying molecular pathology of this common subtype of acute myeloid leukemia. Evidence from these models supports the idea that acute myeloid leukemia 1/core-binding factor beta-subunit (AML1/CBFbeta) has a critical role in the control of the self-renewal capacity of hematopoietic stem cells and their progeny. Moreover, the accumulated data demonstrate that the expression of translocation-encoded AML1 or CBFbeta fusion proteins are insufficient by themselves to induce a full leukemic phenotype. The models that have been developed should prove to be of value for defining the range of mutations that can cooperate with AML1/CBFbeta fusion proteins, and for assessing novel therapies targeted toward the pathways that are altered by the expression of these fusion proteins.
