ABSTRACT
Objective To investigate the effectiveness of decitabine demethylation in treatment of acute leukemia.Methods Methylation specific PCR (MSP) was used to detected the methylation status of Apaf-1 gene promoter.10 cases entering the group.MSP was used to detected the 10 cases methylation status of Apaf-1 promoter between pre-and post-treatment of dicitabine.RT-PCR method used was to detect the differential expression levels of Apaf-1 mRNA in acute leukemia bone marrow mononuclear cell between preand post-treatment of decitabine.Results In post-treatment of decitabine,6 cases Apaf-1 gene promoter was demethylated.The loss expression of Apaf-1 mRNA re-expressed in 4 cases.6 cases Apaf-1 mRNA still express deletion.6 cases patients have Apaf-1 mRNA exprssion deletion,However,4 cases Apaf-1 gene was demethylated,2 cases methylated in post-treatment,maybe related to allele deletion or allelic varriants.Conclusion Post treatment of decitabine.Apaf-1 gene promotor was demethylated and repress the expression of Apaf-1 mRNA,play a key role in apoptosis maybe a new method for treatment of acute leukemia.
