siRNA下调astrocyte elevated gene-1对神经母细胞瘤细胞增殖和凋亡影响的体外研究
Chinese Journal of Pathophysiology(2011)
Abstract
目的:探讨siRNA下调astrocyte elevated gene-1(AEG-1)表达对神经母细胞瘤细胞增殖、凋亡和细胞周期的影响.方法:用设计合成的AEG-1 siRNA转染神经母细胞瘤细胞株M17和SK-N-SH,采用荧光定量RT - PCR技术观察AEG-1 siRNA对AEG-1基因表达的影响;用MTT法和克隆形成实验观察AEG-1 siRNA对神经母细胞瘤细胞的增殖抑制作用;用流式细胞术检测下调AEG-1表达对神经母细胞瘤细胞凋亡及细胞周期的影响.结果:用AEG-1 siRNA转染人神经母细胞瘤细胞,RT - PCR结果证实AEG-1 siRNA能显著基因下调AEG-1表达,与对照组相比有显著差异(P<0.01);MTT法和克隆形成实验结果证明下调AEG-1表达可显著抑制神经母细胞瘤细胞的增殖;流式细胞术检测结果表明下调AEG-1表达可促进神经母细胞瘤细胞凋亡,并将细胞周期阻滞在G0/G1期.结论:AEG-1 siRNA可下调基因在神经母细胞瘤细胞中表达,并抑制神经母细胞瘤细胞增殖,促进细胞凋亡.
