摘    要:目的研究选择性环氧化酶-2(COX-2)抑制剂塞来昔布联合5-Fu对SGC-7901人胃癌细胞增殖及Bcl-2、Bax表达的影响。方法以SGC-7901人胃癌细胞为研究对象,运用不同浓度的塞来昔布联合5-Fu,采用MTT法测定塞来昔布及其与5-Fu联合对胃癌细胞生长的影响,流式细胞仪(FCM)检测处理后细胞周期和凋亡的变化,免疫组化检测Bcl-2、Bax的表达。结果塞来昔布联合5-Fu对胃癌细胞均有抑制作用,且联合用药及单药的抑制率与对照组比较差异有统计学意义(P〈0.05);流式细胞学检测到凋亡峰,其抑制作用呈时间-剂量依赖性;处理后的胃癌细胞进行免疫组化检测,发现联合用药组有更显著的Bcl-2表达下降和Bax表达增强。结论塞来昔布与5-Fu联合对胃癌细胞有协同抑制作用,其机制可能与改变Bcl-2和Bax的表达水平有关。

Abstract:Objective To investigate the effects of Celecoxib,a selective COX-2 inhibitor,with 5-Fu on cell proliferation,Bcl-2 and Bax Expression and apoptos is in SGC-7901 human gastric cancer cell line and to explore its anti-neoplasm mechanism.Methods MTT assay was used to determine cell proliferation after incubation in different concentrations of celecoxib with 5-Fu.The effect of celecoxib with 5-Fu on cell cycle changes and apoptosis of cells was studied by flow cytometry(FCM).The immunohistochemistry measured t...
