Epigenetic therapy in myeloproliferative neoplasms: evidence and perspectives
The classic Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs), which include polycythaemia vera, essential thrombocythaemia and primary myelofibrosis, originate from a stem cell-derived clonal myeloproliferation that manifests itself with variable haematopoietic cell lineage involvement; they are characterized by a high degree of similarities and the chance to transform each ...
متن کاملGenetic–pathologic characterization of myeloproliferative neoplasms
Myeloproliferative neoplasms (MPNs) are clonal hematopoietic stem cell disorders characterized by the proliferation of one or more myeloid lineages. The current study demonstrates that three driver mutations were detected in 82.6% of 407 MPNs with a mutation distribution of JAK2 in 275 (67.6%), CALR in 55 (13.5%) and MPL in 6 (1.5%). The mutations were mutually exclusive in principle except in ...
متن کاملGenetic and epigenetic alterations of myeloproliferative disorders.
The classical BCR-ABL negative myeloproliferative neoplasms (MPN) polycythemia vera, essential thrombocythemia, and primary myelofibrosis are clonal hematopoietic disorders characterized by excessive production of terminally differentiated myeloid cells. In MPN patients, the disease can progress to secondary myelofibrosis or acute myeloid leukemia. Clonal hematopoiesis, disease phenotype, and p...
متن کاملevaluation of common genetic disorders in myeloproliferative neoplasms
introduction: the myeloproliferative neoplasms (mpns) are a heterogeneous group of diseases characterized by excessive production of blood cells by hematopoietic precursors. typically, they include polycythemia vera (pv), essential thrombocythemia (et), idiopathic myelofibrosis(imf), and chronic myeloid leukemia (cml). philadelphia chromosome is the final diagnostic test for cml. recently, jak...
متن کاملMyeloproliferative neoplasms and thrombosis.
Major causes of morbidity and mortality in myeloproliferative neoplasms are represented by arterial and venous complications, progression to myelofibrosis, and transformation to acute leukemia. The pathogenesis of thrombosis results from a complex interplay of clinical and disease-related factors. Abnormalities of blood cells arising from the clonal proliferation of hematopoietic stem cells inv...
