摘  要:目的研究宝藿苷-Ⅰ与As2O3联合应用对食管癌细胞Eca-109增殖的影响。方法取对数生长期Eca-109接种于96孔培养板,宝藿苷-Ⅰ组予以25 mg/L宝霍苷As2O3组予0.18 mg/L As2O3,联合用药组予12.5 mg/L宝藿苷-Ⅰ+0.09 mg/L As2O3,对照组予0.1%DMSO。采用MTT法分析对Eca-109细胞增殖的抑制作用,DNA琼脂糖凝胶电泳分析细胞凋亡,流式细胞术分析细胞周期,Western Blot技术检测C-myc基因蛋白的表达,每组均重复3次。结果 3个用药组均可明显抑制Eca-109细胞的增殖(均P<0.05),但联合用药组抑制作用显著优于单独用药组(P<0.05);3个用药组均可使细胞凋亡,使细胞周期阻滞在G2/M期,使C-myc表达下调,与对照组相比均有显著性差异(P均<0.05),但联合用药组较单药组作用更显著(P<0.05)。结论各自半量的宝藿苷-Ⅰ与As2O3联合应用对Eca-109细胞的增殖抑制有显著的增强作用,明显优于各自的单味应用效果。Objective It is to observe the influence of of baohuoside- I combined with As203 on proliferation of human esophageal carcinoma cell Eca - 109. Methods The cells were divided into 4 groups: 25 mg/L baohuoside - I group (25 mg/ L) , As2O3 group (0.18 mg/L) , combination group ( 12.5 mg/L baohuoside - I and 0. 09 mg/L As203 ) , and control group (0.1% DMSO) , the inhibitory effect on proliferation of Eca - 109 ceils was analyzed by MTT, the apoptosis of Eca - 109 cells was measured with DNA agarose gel electrophoresis, the cell cycle was measured by flow cytometry, the expression of C- myc protein of Eca - 109 cells was measured with western blot, each group were repeated 3 times. Results The proliferation of Eca - 109 cells were inhibited in three drug groups (all P 〈0.05 ) , the inhibitory effect of combination group was superior to alone group (P 〈 0. 05) ; cell apoptosis of Eca- 109 cells was induced significantly in three groups, the cell rate of the G2/ M phase was increased significantly, expression of C - myc protein was decreased significantly than control group ( all P 〈 0. 05 ), and the combination group showed more significant effect than alone group ( P 〈0.05 ). Conclusion Half dose of Baohuoside- I and As2O3 in combination shows a synergistic enhancement on the inhibiting proliferation, and superior to alone group.
