Molecular biology of Philadelphia-negative myeloproliferative neoplasms
Myeloproliferative neoplasms are clonal diseases of hematopoietic stem cells characterized by myeloid hyperplasia and increased risk of developing acute myeloid leukemia. Myeloproliferative neoplasms are caused, as any other malignancy, by genetic defects that culminate in the neoplastic phenotype. In the past six years, since the identification of JAK2V617F, we have experienced a substantial i...
متن کاملMyeloproliferative Disorders BCR-ABL1—Negative Myeloproliferative Neoplasms: A Review of Molecular Biology, Diagnosis, and Treatment
In 2008, the World Health Organization expanded the classification of myeloproliferative disorders based on increasing amounts of molecular and cytogenetic data. Myeloproliferative neoplasms (MPN) that do not contain the BCR-ABL1 mutation include polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). JAK2V617F is the best characterized mutation in BCR-ABL1–nega...
متن کاملLow Frequency of C-MPL Gene Mutations in Iranian Patients with Philadelphia-Negative Myeloproliferative Disorders
Background Myeloproliferative disorders are a group of diseases characterized by increased proliferation of myeloid lineage. In addition to JAK2V617F mutation, several mutations in the c-MPL gene were described in patients with Philadelphia-negative chronic myeloproliferative disorders that could be important in the pathogenesis of diseases. The aim of present study was to investigate the fre...
متن کاملSingle chromosomal abnormalities in Philadelphia-negative chronic myeloproliferative disorders.
BACKGROUND In Philadelphia-negative chronic myeloproliferative disorders (CMPD), increased proliferation with effective maturation of the myeloid lineage is present, while peripheral leukocytosis, thrombocytosis or elevated red blood cell mass are found. This group of disorders includes polycythemia vera (PV), essential thrombocythemia (ET) and idiopathic myelofibrosis (IMF). Furthermore, cases...
متن کاملPhiladelphia chromosome-negative myeloproliferative disorders: an historical perspective.
Polycythemia vera is a prototype and also the most common of the four classical myeloproliferative disorders—chronic myelogenous leukemia (CML), polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). Our understanding of the last three disorders has lagged behind in comparison to our understanding of the molecular basis of CML, which led to the development of t...
