Chronic Myelogenous Leukemia: Approaches to Pharmacological Resistance

2017

Chronic myelogenous leukemia (CML) is a clonal myeloproliferative disorder characterized by the reciprocal t (9:22) chromosomal translocation. This rearrangement produces the socalled Philadelphia chromosome carrying the chimeric Bcr-Abl oncoprotein, p210, responsible of disease progression [1]. Because of its critical role in pathogenesis, the scientific community had focused on targeting Bcr–Abl for treatment of CML. For many years Imatinib (IM), as selective inhibitor of the Tyr-Kinase activity of the oncoprotein, was used to treat CML patients [2]. From 2000 some data relative to IM resistance were available. There are many mechanisms responsible of IM resistance, more often point mutat…
