Abstract

The myelodysplastic syndromes comprise a heterogeneous group of neoplastic disorders characterized by ineffective hematopoiesis with an increased tendency to evolve to acute leukemia. Clinically, the common manifestations include peripheral blood cytopenias of one or more lineages and a normal to hyperplastic marrow. MDS has been defined on the basis of morphological criteria, namely the percentage of blast cells in the bone marrow, by the French-American-British study group. Scoring systems have been developed to include such factors as hemoglobin, leukocyte count and age in the evaluation of MDS prognosis. Although useful in the prediction of clinical course and design of therapy regimens, our understanding of the basis of MDS has come from recent advances in molecular analysis of these disorders. This review describes some of the established and recent contributions to our understanding of the molecular basis of the myelodysplastic syndromes. The authors of the present review have been working in the field of myelodysplastic syndromes for several years and have contributed original papers on the molecular pathogenesis of these disorders. In addition, in the present review they have critically examined articles and abstracts ...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
