摘要: 目的: 研究宝霍苷-Ⅰ与5-FU联合应用对食管癌Eca-109细胞增殖和凋亡的影响。方法:实验设联合用药组 (12.5 mg/L宝霍苷-Ⅰ+12.5 mg/L 5-FU)、阴性对照组 (0.1% DMSO)、25 mg/L宝藿苷-I组和12.5 mg/L 5-FU组,共4组,每组均设3个复孔,每孔100 μl (含Eca-109细胞数为1×104个)。作用24、48、72 h时,采用四甲基偶氮唑盐 (MTT)法分别检测各组Eca-109细胞的增殖;并在作用48 h后,用流式细胞术检测Eca-109细胞凋亡率;用Western blot技术检测Bcl-2、Bax蛋白的表达。结果:宝霍苷-Ⅰ、5-FU单用及其联合应用在24、48和72 h时均可明显抑制Eca-109细胞的增殖,与阴性对照组比较,差异均有统计学意义(P 均<0.05),联合应用的抑制作用显著优于单独应用 (P <0.05)。宝霍苷-Ⅰ、5-FU单独及其联合作用48 h后,均可诱导Eca-109细胞凋亡,均可下调Bcl-2蛋白的表达,上调Bax蛋白的表达,与对照组相比差异均有统计学意义 (P均<0.05),且联合用药组较单独用药组作用明显 (P <0.05)。结论:宝霍苷-Ⅰ与5-FU联合应用对Eca-109细胞的增殖抑制和凋亡诱导有协同作用,可能与下调Bcl-2蛋白的表达、上调Bax蛋白的表达有关。

Abstract: OBJECTIVE: To study the effects of baohuoside-I in combination with 5-FU on the proliferation and apoptosis of human esophageal carcinoma cell Eca-109. METHODS:The cells were divided into 4 groups: combination group (12.5 mg/L baohuoside-I and 12.5 mg/L 5-FU),negative control group (0.1% DMSO),25 mg/L baohuoside-I group and 12.5 mg/L 5-FU group,with 3 holes in each group and 100 μl each hole (1×104 cells ). After treatment for 24,48,72 h,the inhibitory effect on proliferation of Eca-109 cells was analyzed by MTT. After treatment for 48 h,apoptosis of Eca-109 cells was measured with flow cytometry;the expression of Bcl-2 protein and Bax protein of Eca-109 cells was measured with Western blot. RESULTS:Baohuoside-I,5-FU alone and baohuoside-I in combination with 5-FU inhibited proliferation of Eca-109 cells (P all <0.05),the inhibitory effect of the combination group was superior to either alone (P <0.05). After treatment for 48 h,apoptosis of Eca-109 cells was induced significantly,the expression of Bcl-2 protein was decreased and Bax protein was increased significantly than control group (P all <0.05). T he combination group showed more significant effect than either alone (P <0.05). CONCLUSION: Baohuoside-I in combination with 5-FU exerted a synergistic effect on inhibiting proliferation and promoting apoptosis. This effect associated with decreased expression of Bcl-2 and increased expression of Bax.
