Abstract

Objective

This study investigated the effects of rh-TRAIL with or without chemotherapeutic drugs on the apoptosis of the osteosarcoma cell line, MG-63, and the influence of chemotherapeutic drugs on changes in the expression of DR5 and Yin Yang1(YY1) in MG- 63 cells.

Methods

The effects of treatment with rh-TRAIL alone and/or chemotherapeutic drugs on MG-63 cell growth inhibition and apoptosis were measured using the MTT assay, FACS analysis of Annexin V labeled cells, and the mRNA changes of DR5 and YY1 were detected by RT-PCR.

Results

Rh-TRAIL protein inhibited the growth of MG-63 cells, and this inhibition was increased by adriamycin and IFN-γ. Adriamycin and IFN-γ significantly facilitated the induction of the expression of DR5 and reduced the expression of YY1.

Conclusion

The apoptosis-inducing effect of rh-TRAIL in MG-63 cells was enhanced by chemotherapeutic drugs.

TRAIL及其受体在骨肉瘤细胞中的表达及TRAIL、阿霉素和IFN-γ联合作用对MG-63细胞凋亡的影响

目的研究rh-TRAIL联合或不联合化疗药物对MG-63骨肉瘤细胞系凋亡的影响，以及化疗药物对MG-63细胞DR5和阴阳1(YY1)表达变化的影响。方法采用MTT法、Annexin V标记细胞FACS法检测rh-TRAIL和/或化疗药物治疗对MG-63细胞生长抑制和凋亡的影响，RT-PCR检测DR5和YY1 mRNA的变化。结果rh - trail蛋白对MG-63细胞的生长有抑制作用，阿霉素和IFN-γ可增强这种抑制作用。阿霉素和IFN-γ显著促进DR5的表达诱导，降低YY1的表达。结论化疗药物可增强rh-TRAIL对MG-63细胞的诱导凋亡作用。
