BACKGROUND The discovery of Janus kinase 2 (JAK2)-V617F has provided important insight into the pathogenesis of Philadelphia-negative chronic myeloproliferative neoplasms (Ph-negative MPNs); however, the etiology of JAK2(V617F)-negative Ph-negative MPN remains unidentified. MPL(W515L) and MPL(W515K) (MPL(W515L/K)) are 2 gain-of-function mutations, which have been found in some Ph-negative MPN p...

Fluoride pollution in waters has engulfed worldwide regions and an excess of fluoride intake always causes skeletal fluorosis. Herein, a novel hybrid nanomaterial ZrP-MPN was fabricated for fluoride retention by encapsulating nano-ZrP onto macroporous polystyrene materials modified with quaternary ammonium groups. The as-obtained materials exhibited favorable removal of fluoride ions from aqueo...

We previously found that gender influenced the JAK2 V617F allele burden, but it is unknown whether this gender difference in molecular epidemiology influences complications in the myeloproliferative neoplasms (MPNs). Historically, vascular complications represented the most common cause of mortality in polycythemia vera and essential thrombocytosis and contributed to morbidity in primary myelof...

A rapid and precise assay for neuraminidase using 2-(3'-methoxyphenyl)-N-acetyl-alpha-neuraminic acid (MPN) is described. It is proposed that this substrate be used for the standardization of activity of neuraminidases from viral, bacterial, and mammalian sources. MPN is also used as a chromogenic substrate to localize influenza and parainfluenza virus foci in tissue culture. This technique per...

The JAK2(V617F) mutation does not elucidate the phenotypic variability observed in myeloproliferative neoplasm (MPN) families. A putative tumor suppressor gene, TET2, was recently implicated in MPN and myelodysplastic syndromes through the identification of acquired mutations affecting hematopoietic stem cells. The present study analyzed the TET2 gene in 61 MPN cases from 42 families. Fifteen d...

Chronic myelomonocytic leukemia (CMML) is a myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN) overlap syndrome characterized by peripheral blood monocytosis (absolute monocyte count/AMC ⩾ 1 × 10(9)/l, ⩾ 10% of the total white blood cell count) and an inherent risk for leukemic transformation. Monocytosis, however, is not pathognomic for CMML and can be associated with reactive and ...

The Philadelphia chromosome-negative myeloproliferative neoplasms (MPN) are a group of clonal hematopoietic diseases characterized by bone marrow proliferation of one or more of the myeloid cell lineages with no marked alterations in cellular maturation. MPN classically comprise the clinically and pathologically related polycythemia vera (PV), essential thromobocythemia (ET), and primary myelof...

Objective Primary myelofibrosis (PMF) is one of the Philadelphia negative myeloproliferative neoplasms (MPN). The main clinical features are obvious physical symptoms and symptomatic splenomegaly. It may be converse to leukemia and has a shortened life expectancy. Nowadays, the therapy for PMF is aimed at maintaining comfort and there is no curative treatment. PMF with myelodysplastic syndrome ...

OBJECTIVE LNK is an adapter protein negatively regulating the JAK/STAT cell signaling pathway. In this study, we observed the correlation between variation in LNK gene and the clinical type of myeloproliferative neoplasms (MPN). METHODS A total of 285 MPN cases were recruited, including essential thrombocythemia (ET) 154 cases, polycythemia vera (PV) 76 cases, primary myelofibrosis (PMF) 19 c...
