摘要 目的观察选择性COX-2抑制剂塞米昔布(Celecoxib)对Raji细胞增殖、凋亡及细胞周期分布的影响,并检测存活素(Survivin)在细胞中的表达情况。方法应用流式细胞术(FCM)分析Celecoxib对人Burkitt淋巴瘤Raji细胞周期的影响并检测细胞凋亡及存活素在细胞中的表达情况,应用RT-PCR法检测细胞中SurvivinmRNA的表达水平。结果 Celecoxib各浓度组作用于Raji细胞24、48、72h后吸光度值与对照组相比均有显著性差异(P<0.05),同时各浓度组之间以及时间组之间有显著性差异(P<0.05)。Celecoxib各浓度组作用于Raji细胞48h后各浓度组间Cele-coxib对细胞凋亡率和细胞周期的影响、下调Survivin蛋白表达下调SurvivinmRNA相对表达量具有显著性差异(P<0.05)。结论 Celecoxib能够通过诱导凋亡抑制Raji细胞的增殖,其机制可能与抑制Survivin表达有关。
