1. Screening for myeloid mutations in patients with myelodysplastic syndromes and AML with myelodysplasia-related changes
ABSTRACT Introduction: One of the most critical complications in myelodysplastic syndromes (MDS) is the progression to acute myeloid leukemia (AML). The dynamics of clonal evolution in MDS and how acquired mutations can be used as biomarkers to track disease progression remains under investigation. Objective and method: Herein, we investigated the frequenc

2. Clinical and molecular profile of a Brazilian cohort of patients with classical BCR-ABL1-negative myeloproliferative neoplasms
ABSTRACT Background: The classical BCR-ABL1-negative myeloproliferative neoplasms (MPNs) are Polycythemia Vera (PV), Essential Thrombocythemia (ET) and Primary Myelofibrosis (PMF). In developing countries, there are few reports that truly reveal the clinical setting of these patients. Therefore, we aimed to characterize a single center MPN population with a

3. Essential thrombocythemia - a predisponent factor for stroke
SUMMARY The essential thrombocythemia is one of the seven described forms of myeloproliferative neoplasms. It is characterized by megakaryocytic hyperplasia with consequent thrombocytosis maintained in the peripheral blood, favoring the occurrence of thrombo-hemorrhagic phenomena. We present the case of an 81-year-old woman with a history of ischemic stroke

4. Insulin Substrate Receptor (IRS) proteins in normal and malignant hematopoiesis
The insulin receptor substrate (IRS) proteins are a family of cytoplasmic proteins that integrate and coordinate the transmission of signals from the extracellular to the intracellular environment via transmembrane receptors, thus regulating cell growth, metabolism, survival and proliferation. The PI3K/AKT/mTOR and MAPK signaling pathways are the best-charac

5. Philadelphia-negative myeloproliferative neoplasms as disorders marked by cytokine modulation
ABSTRACT Background: Cytokines are key immune mediators in physiological and disease processes, whose increased levels have been associated with the physiopathology of hematopoietic malignancies, such as myeloproliferative neoplasms. Methods: This study examined the plasma cytokine profiles of patients with essential thrombocythemia, primary myelofibrosis,

6. Aplicação do escore prognóstico IPSET-trombose nos pacientes com trombocitemia essencial em um hospital público brasileiro
Resumo Introdução: em pacientes com trombocitemia essencial (TE), complicações vasculares contribuem para morbidade e mortalidade. Para melhor predizer a ocorrência de eventos trombóticos, um escore prognóstico internacional de trombose para TE (IPSET-trombose) foi recentemente desenvolvido. Apresentamos aqui a aplicação desse escore e comparamos s

8. l-Amino acid oxidase isolated from Calloselasma rhodostoma snake venom induces cytotoxicity and apoptosis in JAK2V617F-positive cell lines
ABSTRACT BACKGROUND: Myeloproliferative neoplasms are Philadelphia chromosome-negative diseases characterized by hyperproliferation of mature myeloid cells, associated or not with the Janus kinase 2 tyrosine kinase mutation, JAK2V617F. As there is no curative therapy, researchers have been investigating new drugs to treat myeloproliferative neoplasms, incl

9. Myeloproliferative neoplasms and the JAK/STAT signaling pathway: an overview
ABSTRACTMyeloproliferative neoplasms are caused by a clonal proliferation of a hematopoietic progenitor. First described in 1951 as 'Myeloproliferative Diseases' and reevaluated by the World Health Organization classification system in 2011, myeloproliferative neoplasms include polycythemia vera, essential thrombocythemia and primary myelofibrosis in a subgr

11. Desregulação da apoptose em neoplasias mieloproliferativas crônicas
As neoplasias mieloproliferativas crônicas cromossomo Filadélfia negativas são doenças hematológicas clonais que se caracterizam pela independência ou pela hipersensibilidade dos progenitores hematopoiéticos às citocinas. Os mecanismos celulares e moleculares envolvidos na fisiopatologia das neoplasias mieloproliferativas crônicas ainda não estão

12. Evaluation of the association between the JAK2 46/1 haplotype and chronic myeloproliferative neoplasms in a Brazilian population
OBJECTIVE: The JAK2 46/1 haplotype has recently been described as a major contributing factor to the development of myeloproliferative neoplasm, whether positive or negative forthe JAK2 V617F mutation. The G allele, identified by a single-nucleotide polymorphism known as JAK2 rs10974944, is part of the JAK2 46/1 haplotype. The aim of this study was to verify
