摘要:
采用溶胶凝胶法制备明胶硅氧烷纳米颗粒(GS NPs),分析反应中的不同pH值盐酸溶液对GS NPs的影响,并通过粒径、电位和形貌对GS NPs进行表征。结果表明:pH值3.0盐酸溶液为制备的最佳条件,制备的GS NPs呈无规则球状,分散性较好,平均粒径为250 nm左右且分布集中,表面Zeta电位为38 mV。为评估其作为基因载体的可行性及负载p53基因对肝癌的抑制效果,采用凝胶电泳实验检测GS NPs对pDNA的负载率和释放性,CCK8法检测其生物相容性和激光共聚焦观察细胞内摄取情况以及MTT法、Western blot综合评价其携载pEGFP C1 p53对肝癌细胞的抑制效果,结果显示:GS NPs可有效负载pDNA且最适负载量比为200∶1,在盐溶液下表现出一定的释放性;此外GS NPs具有良好的生物相容性,可携载pDNA逃逸出溶酶体的吞噬,携载pEGFP C1 p53后对肝癌细胞Hep 3b表现出显著的抑制效果,并介导GFP p53融合蛋白的表达。研究结果表明所制备的GS NPs可作为一种基因载体,负载p53基因对肝癌细胞具有一定的抑制效果。
