摘要 目的评估二十二碳六烯酸(DHA)联合氟尿嘧啶(FU)对人胃癌细胞株MGC-803的作用。方法采用MTT法检测DHA、FU单用和联合应用对细胞增殖的影响,Chou-Talalay联合指数原理计算药物单用和合用时的中效浓度(Dm)及合用指数(CI),流式细胞仪检测药物对细胞周期及凋亡的影响,Western blot检测bcl-2和caspase-3蛋白的表达。结果DHA可抑制MGC803细胞生长,低浓度DHA可促进正常细胞生长(P<0.05)。DHA能显著增强FU对胃癌细胞生长的抑制作用,将FU的Dm减少3.6~2.5倍;两者合用抑制效率达30%时呈协同作用(CI<1),并表现为显著的G_0/G_1期阻滞作用(P<0.05)。DHA能提高FU的诱发凋亡作用,促进剪切型caspase-3蛋白表达。结论DHA可抑制胃癌细胞株MGC803生长,与FU对胃癌细胞的抑制具有协同作用,可减少FU用量。 Objective To evaluate the effect of the combination of docosahexaenoic acid(DHA) and fluorouracil(FU) on human gastric carcinoma cell strain MGC803 in vitro.Methods The influences of DHA and FU alone or in combination on cell proliferation was detected using MTT assay.Dose of median(Dm) of drugs(alone or in combination) and the combination index(CI) were calculated using the combination index equation of Chou-Talalay.Cell cycle were examined using flow cytometry.Cell apoptosis was determined by AnnexinV-FIT...
