摘 要:目的:研究化疗药物顺铂应用于宫颈癌HeLa细胞对TRAIL死亡受体DR4、DR5的影响,探讨顺铂与TRAIL协同作用机制。方法:培养HeLa细胞加入顺铂10uM/L1ml培养24h,采用RT-PCR方法检测顺铂对HeLa细胞TRAIL死亡受体DR4、DR5的影响。结果:顺铂组TRAIL死亡受体DR4、DR5的表达较对照组增强。结论:顺铂与TRAIL的协同作用是通过提高TRAIL死亡受体DR4、DR5的表达而实现的。Objective: To study the effect of cisplatin on tumor necrosis factor - related apoptosis - inducing ligand (TRAIL) death receptors ( DR4 and DR5 ) in HeLa cells of cervical carcinoma, explore the mechanism of synergistic effect of cisplatin and TRAIL Methods: HeLa cells were cultured for 24 hours with cisplatin 10 uM/L 1 ml, then the effect of cisplatin on TRAIL death receptors ( DR4 and DRS) was detected by RT - PCR. Results : The expression levels of TRAIL death receptors ( DR4 and DR5 ) in HeLa cells in cisplatin group was significantly higher than that in control group. Conclusion: The synergistic effect of cisplatin and TRAIL is fulfilled by increasing the expression levels of TRAIL death receptors ( DR4 and DRS) in HeLa cells.
