title: [Effect of 5-aza-2'-deoxycytidine on DAPK gene expression in human HL-60 cells].
abstract: This study was aimed to investigate the effect of methylation transferase inhibitor 5-aza-2'-deoxycytidine (5-aza-2dC) of different concentrations on the apoptosis of human acute myeloid leukemia (AML) cell line HL-60 and the expression of DAPK gene in HL-60 cells, as well as to explore the possible anti-AML mechanism of 5-aza-2dC. HL-60 cells were treated by 5-aza-2dC of different concentrations. The effect of 5-aza-2dC on the HL-60 cell morphology was observed by Wright's staining. The effect of 5-aza-2dC on HL-60 cell apoptosis and DAPK mRNA expression was detected by flow cytometry and reverse transcription-polymerize chain reaction (RT-PCR) respectively. The results showed that the 5-aza-2dC induced the apoptosis of HL-60 cells in a concentration-dependent manner; the 5-aza-2dC increased the expression levels of DAPK mRNA in HL-60 cells in a concentration-dependent manner. It is concluded that the apoptosis rate of HL-60 cells and DAPK mRNA expression level displayed a rising trend with 5-aza-2dC concentration increasing. Therefore, DAPK gene may participate in HL-60 cell apoptosis induced by 5-aza-2dC.
