抑制survivin基因的表达对骨肉瘤细胞株U-2OS凋亡的影响
Blockade of survivin promotes the apoptosis of human osteosarcoma cell line U-2OS
摘要
Abstract
Objective:To investigate the effect of surviving on the apoptosis of human osteosarcoma cell line U-2OS. Methods:Atfer transfection with small inference RNA targeting survivin in U-2OS, survivin protein and mRNA expression were measured with western blot and RT-PCR, respectively. U-2OS cells were knockdown with survivin, and then were incubated with cisplatin for the indicated times, cell survival rate, growth inhibitory rate and apoptosis rate were measured with MTT and lfow cytometry, respective;Bcl-2 and Bax protein expressions were measured with western blot. Results:Knockdown of survivin significantly decreased the protein and mRNA expression of survivin (P<0.05). Furthermore, survivin deifciency dramatically augmented the effect of cisplatin on cell survival rate, growth inhibitory rate, apoptosis rate, and the expression of Bcl-2 and Bax (P<0.05).Conclusion:Absence of survivin accelerated the apoptosis of U-2OS, and increased the chemosensitivity of U-2OS towards cisplatin;the present study reveals a novel role of surviving in the treatment of osteosarcoma.关键词
