Abstract:
摘要 目的 研究外源性神经节苷脂GM3对人宫颈癌HeLa细胞增殖、凋亡和VEGF表达的影响。方法 不同浓度GM3干预HeLa细胞24 h后,MTT法检测细胞增殖变化,流式细胞学技术检测细胞凋亡率,RT-PCR技术检测细胞VEGF mRNA表达水平,Western blot技术检测细胞VEGF蛋白水平。结果(1)GM3浓度分别为2 、10、50和250 μmol/L时,HeLa细胞生长抑制率分别为9.8%、32.9%、50.7%和78.6%,半数抑制浓度(IC50)为49.8 μmol/L。(2)GM3浓度分别为10、50和250 μmol/L时,HeLa细胞凋亡率分别为(4.9±0.4)%、(15.1±0.3)%、(24.4±0.7)%。(3)当GM3浓度高于10 μmol/L时,HeLa细胞VEGF mRNA表达水平以及VEGF蛋白表达水平均显著下降(P<0.05)。结论 外源性神经节苷脂GM3能呈浓度依赖性抑制人宫颈癌HeLa细胞增殖,促进HeLa细胞凋亡,下调HeLa VEGF mRNA水平和蛋白水平,提示GM3可能通过调节肿瘤细胞凋亡和肿瘤血管生成而发挥双重抗肿瘤作用
