摘要 目的探讨丝裂原细胞外信号调节激酶(MEK)1/2抑制剂U0126对食管鳞癌细胞迁移的影响及可能的分子机制。方法培养人食管鳞癌细胞系KYSE-150,Transwell迁移实验和划痕实验评价细胞垂直和横向迁移情况,Western印迹法检测上皮间质转化(EMT)相关标记物的蛋白表达。结果Transwell实验结果表明,与对照组相比,不同浓度U0126处理KYSE-150细胞后,细胞垂直向迁移能力明显增强(P<0.05)。细胞划痕实验结果表明,与对照组相比,不同浓度U0126处理KYSE-150细胞后,细胞水平迁移能力明显增强,除0.5μmol/L U012624 h时外,其余差异有统计学意义(P<0.05)。与对照组相比,U0126处理KYSE-150细胞后,p-ERK1/2、E-cadherin表达明显降低,β-catenin表达明显升高(P<0.05)。结论U0126以剂量依赖的方式促进KYSE-150细胞迁移,其机制可能与下调E-cadherin,上调β-catenin表达有关。
