Aberrant EPHB4 gene methylation and childhood acute lymphoblastic leukemia.

ABSTRACT: The present study aimed to investigate the association between aberrant DNA methylation of the promoter region of the ephrin type-B receptor 4 (EPHB4) gene and the development of childhood acute lymphoblastic leukemia (ALL). Bisulfite sequencing polymerase chain reaction (BSP) was performed to determine the methylation density of cytosine-guanine pair islands in the promoter region of EPHB4, in bone marrow samples from 40 children with ALL. The mRNA and protein expression levels of EPHB4 were detected using reverse transcription-quantitative polymerase chain reaction and western blot analysis. A total of 10 children with idiopathic thrombocytopenic purpura (ITP) were recruited as controls. The results revealed that the average methylation density of the bone marrow samples from the patient
