  Objectives: Recently, hyperactivation of the Wnt signaling pathway has been implicated in leukomogenesis, so we studied the epigenetic dysfunction of SFRP1,2 and expression of interleukin2 receptor α chain (IL2Rα, also known as CD25) and its prognostic impact in acute myeloblastic leukemia (AML). Methods: We studied the methylation profile of SFRP1,2 in AML cells by methylation-specific polymerase chain reaction (MSP) and the hyper expression of IL2Rα (CD25) by flowcytometry. Results: We analyzed the methylation profile of SFRP1,2 in 40 de novo AML patients. The percentage of hypermethylation in the patient samples were 37.5% for SFRP1, 12.5% for SFRP2. CD25 was positive in 12(30%) of 40 patients AML. We found that in patients whom 60 years and younger with intermediate risk cytogenetics in de novo AML, hypermethylation of SFRP1 and CD25 were accompanied with relapse (P.. View More»
