摘要: 目的 氧化苦参碱对视网膜母细胞瘤细胞SM-106凋亡的诱导作用及机制。方法 以不同作用时间(24 h、48 h、72 h)和不同作用浓度(12.5 μl/mL、25 μl/mL、50 μl/mL、100 μl/mL)氧化苦参碱处理视网膜母细胞瘤细胞SM-106,分别采用流式细胞仪及western blot检测视网膜母细胞瘤细胞SM-106细胞凋亡及其凋亡因子(Bax、Bcl-2)蛋白表达。结果 氧化苦参碱可促进SM-106细胞体外凋亡,上调Bax蛋白表达及Bax/Bcl-2蛋白表达比值,下调Bcl-2蛋白表达,并呈现剂量及时间依赖性。结论 氧化苦参碱可诱导视网膜母细胞瘤细胞SM-106凋亡,调控凋亡因子Bax、Bcl-2的表达是其可能作用机制。

Abstract: Objective To evaluate the apoptosis and its mechanism of retinoblastoma cells SM-106 induced by oxymatrine. Methods Retinoblastoma cells SM-106 were treated with different time(24 h、48 h、72 h)and different concentrations(12.5 μl/mL, 25 μl/mL, 50 μl/mL or 100 μl/mL) of oxymatrine. The apoptosis and protein expression of apoptosis factors (Bax and Bcl-2) were respectively determined by flow cytometry and western blot. Results Oxymatrine significantly promoted the SM-106 cells apoptosis in vitro, raised Bax protein expression and Bax/Bcl-2 protein expression ratio, reduced the Bcl-2 protein expression, and showed the dose and time dependent. Conclusion Oxymatrine is able to induce the apoptosis in retinoblastoma cells SM-106. Regulating apoptosis related gene Bax and Bcl-2 expression may be the mechanism of apoptosis.
