| Summary: | Osmond J D'Cruz,1 Fatih M Uckun1,21Children's Center for Cancer and Blood Diseases, Children's Hospital Los Angeles, Los Angeles, CA, USA; 2Department of Pediatrics, University of Southern California, Los Angeles, CA, USAAbstract: Bruton's tyrosine kinase (Btk) is intimately involved in multiple signal-transduction pathways regulating survival, activation, proliferation, and differentiation of B-lineage lymphoid cells. Btk is overexpressed and constitutively active in several B-lineage lymphoid malignancies. Btk has emerged as a new antiapoptotic molecular target for treatment of B-lineage leukemias and lymphomas. Preclinical and early clinical results indicate that Btk inhibitors may be useful in the treatment of leukemias and lymphomas.Keywords: tyrosine kinase, personalized therapy, kinase inhibitors, Btk, leukemia, lymphoma
