Inducing Effect of Decitabine on Apoptosis of KMS-18 Myeloma Cells and Its Mechanism / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To investigate the effect of decitabine on proliferation and apoptosis of multiple myeloma KMS-18 cells and its possible mechanism.@*METHODS@#CCK-8 was used to detect cell proliferation, flow cytometry was used to detect the changes of apoptosis, real-time quantitative PCR was used to detect the expression of P53 gene mRNA in myeloma KMS-18 cells, and MSP assay was used to detect the methylation status of P53 gene promoter.@*RESULTS@#The proliferation inhibition and apoptosis of KMS-18 cells significantly increased after treatment by decitabine (P＜0.05). The expression of P53 mRNA increased in KMS-18 cells after treatment of decitabine (P＜0.05). The methylation status of the P53 gene promoter in KMS-18 cells could be partially reversed by decitabine.@*CONCLUSION@#Decitabine can inhibit the proliferation of KMS-18 cells and induce their apoptosis, its mechanism ralates with partially reversing the methylation of P53 gene promoter in KMS-18 cells.
