Resumen
Background: Primary myelofibrosis is a chronic myeloproliferative neoplasm characterized by abnormal megakaryocyte proliferation and fibrosis that destroys healthy bone marrow. This results in extramedullary hematopoiesis, variable blood cell deficiencies, hepatosplenomegaly, general symptoms, progression to leukemia, and a reduced lifespan. Myelofibrosis can occur as a de novo myeloproliferative neoplastic disorder or evolve from other myeloproliferative neoplasms, including Polycythemia Vera or Essential Thrombocytosis. MicroRNAs (miRNAs) are short, non-protein-coding RNA molecules, typicall

Resumen
Primary myelofibrosis (PMF) is a pluripotent hematopoietic stem cell-derived malignancy, included in the heterogeneous group of myeloproliferative neoplasms (MPNs). PMF diagnosis is based on a composite assessment of clinical and laboratory data. The three major diagnostic criteria are: screening for driver mutations, exclusion of other conditions that can cause myelofibrosis, and bone marrow biopsy displaying megakaryocyte changes and fibrosis. PMF treatment options are only partially disease-modifying and consist mainly of symptom control. Recently, a new targeted therapy was introduced for

Abstract Abstract 2854 Molecular mechanisms underlying Philadephia-negative myeloproliferative neoplasm (MPN) pathogenesis were partially unraveled in 2005–2006 with the identification of somatic gain-of-function of JAK2 and MPL, after which many other mutated genes were found. Recently, several new molecular pathogenetic mechanisms were identified. Among them, aberrant microRNA (miRNA) expression especially seems to add to the molecular complexity of MPNs, as specific miRNA signatures capable of discriminating MPN cells from those of normal donors were previously reported (P.

Abstract Myeloproliferative Neoplasms (MPNs) are characterized by clonal proliferative hematopoiesis with increased mature blood cells. The signal-activating mutations such as JAK2V617F increase blood cells, but it remains uncertain how an abnormal hematopoietic cell clone expands in MPNs. We have recently showed that overexpression of the high mobility group AT-hook 2 (HMGA2) causes proliferative hematopoiesis with providing a clonal growth advantage to hematopoietic cells in mice (Ikeda et al, Blood, 2011), suggesting the possibility that HMGA2 contributes to the pathogenesis of MPNs.

Recent studies have suggested that alterations in miRNAs expression could play a critical role in MPN's pathogenesis.

Resumen
Abstract Myeloproliferative neoplasms (MPNs), including polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF), are clonal hematological disorders characterized by proliferation of mature blood cells. Recently, several agents that influence epigenetic modifications, such as histone deacetylase inhibitors (HDACi), as well as JAK2 inhibitors, have been investigated for high-risk MPNs. For example, an HDACi, panobinostat has shown significant efficacy including nearly complete response in PMF (Mascarenhas et al, BJH, 2013), but molecular targets of HDACi remain lar

Primary myelofibrosis (PMF) is a myeloproliferative neoplasm characterized by megakaryocyte (MK) hyperplasia, bone marrow fibrosis, and abnormal stem cell trafficking. PMF may be associated with somatic mutations, about 90% of patients harbor one of three “driver” mutations, with mutational frequencies of approximately 60%, 22% and 6% for JAK2, CALR and MPL, respectively. Other “non-driver” mutations have also been described in PMF involving different cellular targets such as epigenetic regulatory pathways genes (ASXL1, DNMT3A, EZH2, IDH1 and IDH2, TET2), splicing factor genes (SRSF2, SF3B1) a

Clinically chronic myeloproliferative neoplasms are biphasic or triphasic diseases that are usually diagnosed in the initial ‘chronic’, ‘indolent’, or ‘stable’ phase and then spontaneously evolve after some years into an advanced phase. In patients with chronic myeloid leukaemia, the advanced phase can sometimes be subdivided into an earlier accelerated phase and a later blast phase resembling acute leukaemia.
