The Burden of JAK2V617F Mutated Allele in Turkish Patients With Myeloproliferative Neoplasms
BACKGROUND Studies regarding the impact of JAK2V617F allele burden on phenotypic properties and clinical course in Philadelphia-negative myeloproliferative neoplasms (Ph-negative MPNs) have reported variable results. We aimed to analyze the association of mutated JAK2V617F allele burden with laboratory characteristics and clinical phenotype in Turkish patients (107 essential thrombocythemia (ET...
متن کاملHigh Frequency of Endothelial Colony Forming Cells Marks a Non-Active Myeloproliferative Neoplasm with High Risk of Splanchnic Vein Thrombosis
Increased mobilization of circulating endothelial progenitor cells may represent a new biological hallmark of myeloproliferative neoplasms. We measured circulating endothelial colony forming cells (ECFCs) in 106 patients with primary myelofibrosis, fibrotic stage, 49 with prefibrotic myelofibrosis, 59 with essential thrombocythemia or polycythemia vera, and 43 normal controls. Levels of ECFC fr...
متن کاملMyeloproliferative Neoplasms Associated with Mutation in JAK2V617F and Tyrosine Kinase Inhibitors as Therapeutic Strategy
MPNs including a heterogeneous group of clonal or oligoclonal hamtopathies characterized by proliferation and accumulation of mature myeloid cells. JAK2 tyrosine kinase mutation is the most common molecular lesion identified in 90% of cases. JAK2 is involved in EPO signaling pathway, and mutations in it lead to EPO-independent spontaneous phosphorylation. Most tyrosine kinase inhibitors (TKI) a...
متن کاملPrognostic significance of ASXL1, JAK2V617F mutations and JAK2V617F allele burden in Philadelphia-negative myeloproliferative neoplasms
BACKGROUND Despite insights into the genetic basis of Philadelphia-negative myeloproliferative neoplasms (Ph-negative MPNs), a significant proportion of essential thrombocythemia (ET) and primary myelofibrosis (PMF) patients present with no known MPN disease alleles. There were no previous studies investigating the impact of ASXL1 mutations in Ph-negative MPNs in Turkey. In the current study, w...
متن کاملCardiac hypertrophy associated with myeloproliferative neoplasms in JAK2V617F transgenic mice
BACKGROUND Myeloproliferative neoplasms (MPNs) are blood malignancies manifested in increased production of red blood cells, white blood cells, and/or platelets. A major molecular lesion associated with the diseases is JAK2V617F, an activation mutation form of tyrosine kinase JAK2. Cardiovascular events represent the leading cause of morbidity and mortality associated MPNs, but the underlying m...
