In 2010, chronic myeloid leukemia (CML) accounted for 11 of all adult leukemias diagnosed inside the Usa.1,two CML is characterized by the fusion of a portion in the ABL1 oncogene on chromosome 9 with the breakpoint cluster area gene (BCR) on chromosome 22 to type the BCR-ABL1 gene.1 This oncogene encodes a constitutively active tyrosine kinase protein (BCR-ABL1) which will activate many signal transduction pathways affecting hematopoietic cell growth and survival.3 BCR-ABL1 tyrosine kinase inhibitors (TKIs) (imatinib, dasatinib, and nilotinib) are presently the mainstays of CML treatment.four Dasatinib can be a prototypic short half-life TKI (plasma half-life about 4 to 6 hours)5 that inhibits BCR-ABL1 with a potency 325-fold that of imatinib in vitro.Correspondence: Neil P Shah UCSF ematology/Oncology, Suite M1286, Box 1270, 505 Parnassus Ave, San Francisco, CA 94143, USA Tel +1 415 476 3303 Fax +1 415 476 3726 Email [email protected] your manuscript | dovepressDovepresshttp://dx.doi.org./10.2147/CPAA.SClinical Pharmacology: Advances and Applications 2013:5 85?7 ?2013 Wang et al, publisher and licensee Dove Healthcare Press Ltd.
