Demethylation of a hypermethylated P15/INK4B gene in patients with myelodysplastic syndrome by 5-Aza-2′-deoxycytidine (decitabine) treatment

Abstract excerpt

p16 and p15, 2 inhibitors of cyclin-dependent kinases, are frequently hypermethylated in hematologic neoplasias. Decitabine, or 5-Aza-2'-deoxycytidine, reverts hypermethylation of these genes in vitro, and low-dose decitabine treatment improves cytopenias and blast excess in ~50% of patients with high-risk myelodysplastic syndrome (MDS). We examined p15 and p16 methylation status in bone marrow mononuclear cells...
