摘要:
 【摘要】 目的 探讨血管内皮细胞(vascular endothelial cell,VEC)增殖过程中碘离子与血管内皮生长因子(VEGF)及其受体的关系。方法 ① 采用CCK?蛳 8法检测碘离子与VEGF抑制剂作用后VEC的增殖率。② 采用蛋白质印迹技术(Western印迹法)检测碘离子对血管内皮生长因子受体2(VEGFR?蛳 2)磷酸化的影响。结果 ① 在300 μg/L碘离子环境中,使用VEGF抑制剂并不能抑制VEC的增殖(P < 0.05)。② 一定浓度的碘离子可促进VEGFR?蛳 2(Tyr1214)磷酸化水平上调(P < 0.05)。③ 碘离子对VEGFR?蛳 2(Tyr1175,Tyr951位点)的磷酸化无影响。结论 ① 碘离子促进VEC增殖并不依赖于VEGF对膜受体的刺激,碘离子可视为促VEC增殖的独立因素。② 碘离子通过刺激膜受体VEGFR?蛳 2(Tyr1214)磷酸化水平上调,介导VEC迁移。③ 碘离子对VEGFR?蛳 2的Tyr1175位点的磷酸化无影响,其对VEC的促增殖效应并不是通过作用于膜受体。
