The association between somatic JAK2 mutation and myeloproliferative neoplasms (MPNs) is now well established. However, because JAK2 mutations are associated with heterogeneous clinical phenotypes and often occur as secondary genetic events, some aspects of JAK2 mutation biology remain to be understood. We recently described a germline JAK2V617I mutation in a family with hereditary thrombocytos...

An increased expression of antiapoptotic molecules is often found in malignant cells, where it contributes to their clonal expansion by conferring an improved survival ability. We found that erythroid precurors derived from patients with polycythemia vera (PV) with medium and high JAK2V617F mutation rates often express elevated levels of the antiapoptotic molecules Bcl-2 and Bcl-X(L) (5 of 12 p...

JAK-STAT signaling is involved in the regulation of cell survival, proliferation, and differentiation. JAK tyrosine kinases can be transiently activated by cytokines or growth factors in normal cells, whereas they become constitutively activated as a result of mutations that affect their function in tumors. Specifically, the JAK2V617F mutation is present in the majority of patients with myelopr...

Aberrant activation of Janus kinase 2 (JAK2) caused by somatic mutation of JAK2 (JAK2V617F) or the thrombopoietin receptor (MPLW515L) plays an essential role in the pathogenesis of myeloproliferative neoplasms (MPNs), suggesting that inhibition of aberrant JAK2 activation would have a therapeutic benefit. Our novel JAK2 inhibitor, NS-018, was highly active against JAK2 with a 50% inhibition (IC...

Paroxysmal nocturnal hemoglobinuria (PNH) is a hemolytic and pro-thrombotic disorder associated with the clonal expansion of hematopoietic stem cells harboring somatic mutations in the PIG-A gene. Mutations in PIG-A result in a lack of surface expression of all glycosylphosphatidylinositol (GPI)-anchored proteins, including the complement inhibitors CD55 and CD59, which is responsible for the h...

DOI: 10.5581/1516-8484.20130074 The identification of the association of a JAK2 gene mutation with chronic myeloproliferative neoplasms (cMPN) negative for BCR-ABL(1,2) has allowed significant advances in the understanding of this group of hematologic diseases. The JAK2 gene, located on chromosome 9p24, encodes the JAK2 protein which is a cytoplasmic tyrosine kinase that plays an important role...
