Bcr-Abl and inhibition of apoptosis in chronic myelogenous leukemia cells.
Chronic myelogenous leukemia (CML) cells are highly resistant to apoptosis induced by chemotherapeutic drugs. The observation that production of Bcr-Abl is the initiating event in CML has focussed attention on the survival signals triggered by this oncogene. A number of signal transducers and transcription factors have been associated with the antiapoptotic phenotype of CML cells, some of which lead to the expression and/or activation of members of the Bcl-2 family of apoptosis modulators, such as Bcl-xL and Bad. In this article, recent advances in understanding the antiapoptotic pathways triggered by Bcr-Abl in CML cells, are discussed.
