Abstract

To investigate the relationship between LRP15 gene promoter region methylation and its gene expression in acute leukemia patients, the status of LRP15 gene promoter region methylation was detected by MS-PCR and the gene expression was detected by RT-PCR in bone marrow samples from leukemia patients. The results indicated that the LRP15 gene expression was 47.6% in complete remission (CR) patients and 16.7% in non-CR patients respectively, while LRP15 gene promoter region methylation was 38.1% in CR group and 72.2% in non-CR group respectively. No relationship was found between LRP15 gene promoter region methylation and its expression (P = 0.0087). It is concluded that the methylation in LRP15 gene promoter region may not be the only reason for LRP15 gene silence.
