mirs are 17-25 nucleotide non-coding rnas. these rnas target approximately 80% of protein coding mrnas. mirs control gene expression and altered expression of them affects the development of cancer. mirs can function as tumor suppressor via down-regulation of proto-oncogenes and may function as oncogenes by suppressing tumor suppressors. myeloproliferative neoplasias (formerly known as chronic ...

background: myeloproliferative neoplasms (mpns) are clonal malignant diseases that represent a group of conditions including polycythemia vera (pv), essential thrombocythemia (et) and primary myelofibrosis (pmf). the aim of this study was to evaluate possible correlations between jak2v617f allele burden and clinicohematologic characteristics in iranian patients with mpns. we also aimed at deter...

BACKGROUND Myeloproliferative neoplasms constitute a group of diverse chronic myeloid malignancies that share pathogenic features such as acquired mutations in the JAK2, TET2, CBL and MPL genes. There are recent reports that a JAK2 gene haplotype (GGCC or 46/1) confers susceptibility to JAK2 mutation-positive myeloproliferative neoplasms. The aim of this study was to examine the role of the JAK...

Chronic myeloproliferative neoplasms arise from clonal proliferation of hematopoietic stem cells. According to the World Health Organization myeloproliferative neoplasms are classified as: chronic myelogenous leukemia, polycythemia vera, essential thrombocythemia, primary myelofibrosis, chronic neutrophilic leukemia, chronic eosinophilic leukemia, hypereosinophilic syndrome, mast cell disease, ...

Most DNA methylation studies in classic Philadelphia-negative myeloproliferative neoplasms have been performed on a gene-by-gene basis. Therefore, a more comprehensive methylation profiling is needed to study the implications of this epigenetic marker in myeloproliferative neoplasms. Here, we have analyzed 71 chronic (24 polycythemia vera, 23 essential thrombocythemia and 24 primary myelofibros...

A diagnostic approach of myeloproliferative neoplasms, according to the 2008 WHO classification system for hematological malignancies, has to consider clinical, molecular, and cytogenetic information as well as bone marrow histology. A diagnosis of chronic myeloid leukemia requires the presence of BCR-ABL-1, and the Philadelphia chromosome-negative (Ph-1-negative) myeloproliferative neoplasms c...

introduction: the myeloproliferative neoplasms (mpns) are a heterogeneous group of diseases characterized by excessive production of blood cells by  hematopoietic precursors. typically, they include polycythemia vera (pv), essential thrombocythemia (et), idiopathic myelofibrosis(imf), and chronic myeloid leukemia (cml). philadelphia chromosome is the final diagnostic test for cml. recently, jak...

myeloproliferative neoplasms (mpns) such as polycythemia vera, essential thrombocythemia, primary myelofibrosis and chronic myeloid leukemia have too similar and accurate way to differentiate their is study of genetic disorders in these patients. philadelphia chromosome is a sure way to definitively diagnose cml. recently, jak2v617f mutation introduced as a diagnostic marker for other myeloprol...

According to the World Health Organization (WHO) classification of tumors of hematopoietic and lymphoid tissues, myelodysplastic/myeloproliferative neoplasms are clonal myeloid neoplasms that have some clinical, laboratory, or morphologic findings that support a diagnosis of myelodysplastic syndrome, and other findings that are more consistent with myeloproliferative neoplasms. These disorders ...
