Mutation of JAK2 in the myeloproliferative disorders: timing, clonality studies, cytogenetic associations, and role in leukemic transformation.
The identification of an acquired mutation of JAK2 in patients with myeloproliferative disorders has raised questions about the relationship between mutation-positive and mutation-negative subtypes, timing of the JAK2 mutation, and molecular mechanisms of disease progression. Here we demonstrate that patients with V617F(-) essential thrombocythemia do not commonly progress to become V617F(+). C...
متن کاملOncogenes in myeloproliferative disorders.
Myeloproliferative disorders (MPDs) constitute a group of hematopoietic malignancies that feature enhanced proliferation and survival of one or more myeloid lineage cells. William Dameshek is credited for introducing the term "MPDs" in 1951 when he used it to group chronic myeloid leukemia (CML), polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF) under one cl...
متن کاملMyeloproliferative disorders and its associated mutations
Myeloproliferative Neoplasm (MPN) are a clonal disorder in hematopoietic stem cells (HSC). MPN is categorized to 8 subclasses, including chronic myeloid leukemia (CML), polycythemia vera (PV), essential thrombocytopenia (ET), primary myelofibrosis (PMF), systematic mastositosis (SM), chronic eosinophilic leukemia (CEL), chronic neutrophilic leukemia (CNL), and unclassified myelofibrosis disorde...
متن کاملChronic Myeloproliferative Disorders
JAK2, an acquired mutation of JAK2, is present in a majority of patients with polycythemia vera and to a lesser extent among patients with the other myeloproliferative disorders. We analyzed the effect of JAK2 on the expression of polycythemia rubra vera 1(PRV-1), using an in vitro model. Compared to wild-type JAK2, the presence of JAK2 increased both PRV-1 protein and mRNA levels in murine mye...
متن کاملDOWN\'S SYNDROME: CYTOGENETIC STUDIES IN 150 CASES IN TEHRAN
Cytogenetic studies were performed on 150 cases of Down's syndrome (DS) in Iran. The standard trisomy 21 was found in 132 (88 % ) and translocation-trisomy 21 (+21) in 18 (12%) patients, i.e., t(21,21) in 1(0.63%) and mosaicism in 17(11.33%) cases. The comparison of the frequencies for mosaicism between different populations such as Denmark, Hungary, Egypt, Iraq, India, Australia and Iran ...
