Molecular mechanisms associated with leukemic transformation of MPL-mutant myeloproliferative neoplasms

Haematologica, 2010
Somatic activating mutations in MPL, the thrombopoietin receptor, occur in the myeloproliferative neoplasms, although virtually nothing is known about their role in evolution to acute myeloid leukemia. In this study, the MPL T487A mutation, identified in

Stat5 is critical for the development and maintenance of myeloproliferative neoplasm initiated by Nf1 deficiency

Haematologica, 2016
Juvenile myelomonocytic leukemia is a rare myeloproliferative neoplasm characterized by hyperactive RAS signaling. Neurofibromin1 (encoded by the NF1 gene) is a negative regulator of RAS activation.

Hybrid or Mixed Myelodysplastic/Myeloproliferative Disorders – Epidemiological Features and Overview

Frontiers in Oncology, 2021
The WHO-category Myelodysplastic/Myeloproliferative neoplasms (MDS/MPNs) recognizes a unique group of clonal myeloid malignancies exhibiting overlapping features of myelodysplastic as well as myeloproliferative neoplasms.

Myeloproliferative neoplasms in children [PDF]

Journal of Hematopathology, 2015
Myeloproliferative neoplasms (MPN) are a group of clonal hematopoietic stem cell disorders characterized by aberrant proliferation of one or more myeloid lineages often with increased immature cells in the peripheral blood. The three classical BCR-ABL-negative MPNs are: 1) polycythemia vera (PV), 2) essential thrombocythemia (ET), and 3) primary ...

Bone marrow morphology is a strong discriminator between chronic eosinophilic leukemia, not otherwise specified and reactive idiopathic hypereosinophilic syndrome

Haematologica, 2017
Chronic eosinophilic leukemia, not otherwise specified can be difficult to distinguish from idiopathic hypereosinophilic syndrome according to the current World Health Organization guideline.

Novel therapeutics in myeloproliferative neoplasms [PDF]

Journal of Hematology & Oncology, 2020
AbstractHyperactive signaling of the Janus-Associated Kinase/Signal Transducers and Activators of Transcription (JAK/STAT) pathway is central to the pathogenesis of Philadelphia-chromosome-negative myeloproliferative neoplasms (MPN), i.e., polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) which are characterized by

Tissue‐Resident Myeloid and Histiocytic Cells in Health and Disease: Novel Emerging Concepts

American Journal of Hematology, EarlyView.
ABSTRACT Although all myeloid cells are considered to derive from hematopoietic stem cells, the cells in each myeloid lineage are heterogeneous populations, and their distribution and functions vary, depending on underlying physiologic and pathologic processes, age, sex, and genetic and epigenetic signatures.

Triple A Plus (AAA+) Survival Prediction Model for Essential Thrombocythemia: Analysis Involving 7308 Patients

American Journal of Hematology, EarlyView.
A new risk model for essential thrombocythemia that is based on complete blood cell count‐derived parameters and host‐related factors. ABSTRACT Survival prediction models in essential thrombocythemia (ET) include the International Prognostic Scoring System (IPSET) and the more recently introduced triple‐A (AAA) prognostic score.

Risk Factors for and Impact of Pre‐Engraftment Syndrome on Outcomes Following Single‐Unit Cord Blood Transplantation in Adults

American Journal of Hematology, EarlyView.
ABSTRACT Pre‐engraftment syndrome (PES) is a unique complication of cord blood transplantation (CBT) whose risk factors and impact on transplant outcomes remain controversial. Using a nationwide database in Japan, we analyzed a total of 3734 patients who underwent single‐unit CBT.
