Megakaryocytic morphology in Janus kinase 2 V617F positive myeloproliferative neoplasm
CONTEXT Alterations in megakaryocyte morphology are the hallmark of myeloproliferative neoplasms (MPNs). These neoplasm are also associated with Janus kinase 2 (JAK2) V617F mutation in nearly 95% patients with polycythemia vera (PV), 40% patients of essential thrombocythemia (ET) and 50% patients of myelofibrosis (MF). The utility of megakaryocyte morphology in these disorders in correlation wi...
متن کاملLimited efficacy of BMS-911543 in a murine model of Janus kinase 2 V617F myeloproliferative neoplasm.
Activation of Janus kinase 2 (JAK2), frequently as a result of the JAK2(V617F) mutation, is a characteristic feature of the classical myeloproliferative neoplasms (MPNs) polycythemia vera, essential thrombocythemia, and myelofibrosis, and it is thought to be responsible for the constitutional symptoms associated with these diseases. BMS-911543 is a JAK2-selective inhibitor that induces apoptosi...
متن کاملDevelopment of paroxysmal nocturnal hemoglobinuria in CALR-positive myeloproliferative neoplasm
Paroxysmal nocturnal hemoglobinuria (PNH), a disease characterized by intravascular hemolysis, thrombosis, and bone marrow failure, is associated with mutations in the PIG-A gene, resulting in a deficiency of glycosylphosphatidylinositol-anchored proteins. Many hypotheses have been posed as to whether PNH and PIG-A mutations result in an intrinsic survival benefit of CD55(-)/CD59(-) cells or an...
متن کاملCorrelations between Janus Kinase 2 V617F Allele Burdens and Clinicohematologic Parameters in Myeloproliferative Neoplasms
BACKGROUND This study evaluated potential correlations between the allele burden of the Janus kinase 2 (JAK2) V617F mutation and clinicohematologic characteristics in patients with myeloproliferative neoplasms (MPN). METHODS Clinical and hematologic features were reviewed for 103 MPN patients, including patients with polycythemia vera (PV, 22 patients), essential thrombocythemia (ET, 64 patie...
متن کاملDiagnostic Usefulness of the Janus Kinase 2 Mutation in non BCR/ABL Myeloproliferative Disorders
BACKGROUND We investigated the Janus kinase 2 (JAK2) mutation and its diagnostic value in patients suffering with non BCR/ABL myeloproliferative diseases (nMPD) or other reactive conditions. METHODS We reviewed the clinical records of 83 patients who underwent bone marrow (BM) examinations with suspect of nMPD. The diagnoses of nMPD were made based on the WHO criteria since 2001 and the PVSG ...
