| 摘 要： | 目的 研究选择性COX2抑制剂尼美舒利(Nimesulide)对结肠癌细胞株LOVO生长的影响以及其参与抑制肿瘤血管转移的可能机制.方法 采用四甲基偶氮唑蓝(MTT)比色法观察尼美舒利对结肠癌细胞增殖的抑制,电镜下观察尼美舒利作用后细胞的超微结构变化,ELISA法检测尼美舒利对上清液中血管内皮生长因子(VEGF)的影响.结果 MTT显示尼美舒利能抑制LOVO的增殖,呈剂量和浓度依赖性.0.2 mmol/L尼美舒利作用72 h后电镜观察可见典型的凋亡小体.尼美舒利作用后上清液中VEGF的含量呈剂量依赖性下调.结论 尼美舒利可抑制结肠癌细胞株LOVO的生长,促进其凋亡,还可下调细胞上清中的VEGF含量,推测其通过抑制VEGF释放,从而抑制肿瘤的生长及浸润转移.
