Myelodysplastic syndrome.
The last decade has witnessed a multistep evolution in the understanding of the natural history, clinical manifestations, and some of the molecular mechanisms that underlie the ineffective hematopoiesis and leukemic transformation in the myelodysplastic syndrome (MDS). The international prognostic scoring system, FAB, and WHO classifications have helped define specific subgroups with their char...
متن کاملMyelodysplastic Syndrome
The hallmark of neoplastic disease, including myelodysplastic syndrome (MDS), is clonal proliferation of cells. Clonal proliferation is the consequence of acquired somatic mutation that confers a proliferative advantage to cells. For the myelodysplastic syndrome, the ability to identify clonally derived cells has provided valuable information about the molecular pathogenesis of the disease, the...
متن کاملMyelodysplastic syndrome.
During the past 15 years, important progress has been made in the understanding of the biology and prognosis of myelodysplastic syndrome (MDS). MDS is a clonal disorder characterized by ineffective hematopoiesis, which can lead to either fatal cytopenias or acute myelogenous leukemia (AML). Risk-adapted treatment strategies were established because of the high median age (60-75 years) of the MD...
متن کاملTumor suppressor microRNAs are downregulated in myelodysplastic syndrome with spliceosome mutations
Spliceosome mutations are frequently observed in patients with myelodysplastic syndromes (MDS). However, it is largely unknown how these mutations contribute to the disease. MicroRNAs (miRNAs) are small noncoding RNAs, which have been implicated in most human cancers due to their role in post transcriptional gene regulation. The aim of this study was to analyze the impact of spliceosome mutatio...
متن کاملaberrant methylation-mediated suppression of apaf1 in myelodysplastic syndrome
background: myelodysplastic syndromes (mdss) include a diverse group of clonal bone marrow disorders characterized by ineffective hematopoiesis and pancytopenia.it was found that down regulation of apaf1, a putative tumor suppressor gene (tsg),leads to resistance to chemotherapy and disease development in some cancers. in this study, we investigated the relation of apaf1 methylation status with...
