Epigenetic effects of decitabine on acute lymphoblastic and acute promyelocytic leukemia cells
Background: Decitabine (5-aza-2'-deoxycytidine, DAC) is a deoxycytidine analog currently used as an effective drug against myelodysplastic syndromes and acute myeloid leukemia. Although various studies have pointed out the epigenetic effects of this drug, its epigenetic mechanisms in different leukemic cell lines are not specified. In this lab trial study, possible epigenetic effects of decitab...
متن کاملEffects of 5-aza-2'-deoxycytidine on fetal hemoglobin levels, red cell adhesion, and hematopoietic differentiation in patients with sickle cell disease.
Fetal hemoglobin (HbF) decreases polymerization of sickle hemoglobin (HbS) and improves outcomes in sickle cell disease (SSD). Therefore, a therapeutic goal in SSD is pharmacologic reactivation of HbF. Silencing of the gamma-globin (HbF) gene is associated with DNA methylation. The cytosine analog 5-aza-2'-deoxycytidine (decitabine) hypomethylates DNA by inhibiting DNA methyltransferase. We exa...
متن کاملDecitabine, a DNA methyltransferase inhibitor, reduces P-glycoprotein mRNA and protein expressions and increases drug sensitivity in drug-resistant MOLT4 and Jurkat cell lines.
Multidrug resistance (MDR) is a major clinical obstacle in the treatment of several cancers including hematological malignancies and solid tumors. The ATP-binding cassette transporter B1 (ABCB1) gene and its product, P-glycoprotein (P-gp), is one molecule that is involved in drug resistance. Here we report on the effect of decitabine (5-aza-2'-deoxycytidine), an inhibitor of DNA methyltransfera...
متن کاملAn update on the safety and efficacy of decitabine in the treatment of myelodysplastic syndromes
Myelodysplastic syndromes (MDS) are clonal bone marrow malignancies characterized by peripheral cytopenias and dysplastic changes in the bone marrow with various clinical features. Patients with MDS, in particular those with intermediate-2 (Int-2) and high-risk disease, have a poor prognosis. The mainstay of treatment includes cytoxic chemotherapy and supportive care. Over the last decade, prom...
متن کاملEffect of 5-aza-2′-deoxycytidine on p16INK4a, p14ARF, p15INK4b Genes Expression, Cell Viability, and Apoptosis in PLC/PRF5 and MIA Paca-2 Cell Lines
Background: Mammalian cell division is regulated by a complex includes cyclin-dependent kinases (Cdks) and cyclins, Cdk/cyclin complex. The activity of the complex is regulated by Cdk inhibitors (CKIs) compressing CDK4 (INK4) and CDK-interacting protein/kinase inhibitory protein (CIP/KIP) family. Hypermethylation of CKIs has been reported in various cancers. DNA methyltransferase inhibitors (DN...
