摘要 目的探讨U0126、SB203580、PD98059和LY294002对体外缺氧状态下人肺癌细胞A549侵袭力的影响。方法由DFOM建立缺氧环境,U0126、SB203580、PD98059和LY294002处理A549细胞,采用细胞培养、BD细胞培养小室、Giemsa染色和免疫细胞化学染色等方法,检测细胞侵袭力的变化和E-cadherin蛋白的表达。结果A549细胞在缺氧状态下高侵袭力24h后即受到抑制剂明显抑制,其中以PD98059的作用最显著;E-cadherin蛋白的表达也明显上调。结论U0126、SB203580、PD98059和LY294002具有抗肿瘤侵袭的作用,具体机制有待于进一步研究。
