Oncogenes 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 کاملMegakaryoblastic transformation of chronic granulocytic leukemia.
Three cases of megakaryoblastic transformation of chronic granulocytic leukemia (CGL) are reported. In each case, the leukemic transformation had morphologic features suggesting megakaryocytic differentiation. This was confirmed by positive immunostaining with a monoclonal antibody (HP1-1D) specific for platelet and megakaryocyte glycoprotein IIb/IIIa antigen, which was expressed by the majorit...
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 کاملEosinophilic myeloproliferative disorders.
Despite recent attempts to define and classify patients with marked eosinophilia and features consistent with myeloproliferative disease, areas of controversy remain. These are particularly apparent in situations in which multiple lineages are involved in a clonal process and clinical manifestations are overlapping. Although the introduction of new molecular diagnostics and targeted therapies h...
