摘要 [目的]探讨Sp1转录因子在人肺腺癌细胞株A549中对survivin基因表达影响。[方法]电泳迁移率分析(EMSA)检测A549细胞核蛋白与标记的survivin启动子序列在有、无mithramycin时的结合情况。用不同浓度mithramycin处理A549细胞,RT-PCR检测survivin mRNA的表达。[结果]标记的survivin启动子序列-126bp~-106bp与核蛋白作用,出现DNA-核蛋白结合条带,经mithramycin预处理的相同序列出现减弱的DNA-核蛋白结合条带;序列-186bp~-166bp与核蛋白作用后无相应条带。mithramycin使A549细胞survivin mRNA表达显著下降。[结论]survivin启动子-121bp~-116bp处存在Sp1结合位点,mithramycin抑制Sp1与此位点的结合;-178bp~-175bp处可能不存在Sp1结合位点。mithramycin抑制survivin mRNA表达,抑制作用具有浓度依赖性。
