Analysis of apoptosis and all cycle regulatory gene expression in myelodysplastic syndromes (MDS)

Abstract

Myelodysplastic syndromes (MDS) constitute a heterogeneous group of clonal haematopoietic disorders that exhibit ineffective haematopoiesis with an increased risk of transformation to acute myeloid leukaemia (AML). A delicate balance exists between accelerated programmed cell death (apoptosis) and proliferation (cell cycle) of the leukemic haematopoietic stem cell that permits many patients to survive for years. When the balance shifts toward proliferation of the leukemic clone, AML develops, with a poor outcome for most but not all patients. Ιn the last few years τhere have been a large number of studies that examine alterations of the expression of numerous genes in the diverse types of MDS. Taking these into consideration, the aim of the present study was to identify molecular alterations in the bone marrow of adult patients with de novo MDS, more precisely to detect alterations of cell cycle regulatory genes, particularly CDK1, CDK2, CDK3, CDK4, p27, p21, PISSLRE, p16, cyclins A, B ...
