        摘   要   目的:研究瓜蒂水提物和醇提物对食管癌 TE-1、EC-1 细胞增殖、迁移、克隆形成的影响及作用机制。方法:体外培养
        TE-1、EC-1细胞,分别加入质量浓度均为0、1.562 5、3.125、6.25、12.5、25、50、100、200 μg/mL的瓜蒂水提物或醇提物(以提取物粉
        末计)进行培养,采用 MTT 法检测细胞的生长抑制率并计算半数抑制浓度(IC50 )。将 TE-1、EC-1 细胞分为 TE-1/EC-1 空白组、
        TE-1/EC-1瓜蒂水提物组(药液浓度均为IC50 )、TE-1/EC-1瓜蒂醇提物组(药液浓度均为IC50 ),采用实时无标记细胞分析(RTCA)法
        检测各组细胞的增殖与迁移,绘制细胞增殖、迁移曲线;采用显微镜观察各组细胞形态学的变化;采用软琼脂克隆形成试验分析各
        组细胞克隆形成能力的变化,并计算细胞克隆形成率;采用流式细胞仪检测各组细胞的细胞周期、凋亡率;采用Western blotting检
        测各组细胞表皮生长因子受体(EGFR)、蛋白激酶C-α(PKC-α)的相对表达量。结果:瓜蒂水提物作用于TE-1、EC-1细胞的IC50分
        别为49.24、76.38 μg/mL,瓜蒂醇提物作用于TE-1、EC-1细胞IC50分别为9.08、14.53 μg/mL;瓜蒂水提物和醇提物加药后30 h内对
        细胞有增殖抑制作用;瓜蒂水提物和醇提物加药后60 h内对细胞有迁移抑制作用。与TE-1/EC-1空白组比较,各加药组细胞数量
        明显减少,细胞结构松散,多数细胞轮廓消失、变圆等;细胞克隆形成率显著下降(P<0.01);G2期细胞百分率显著升高(P<0.01),
        G1期、S 期细胞百分率显著降低(P<0.05);早、晚期凋亡率均显著增加(P<0.05);EGFR、PKC-α蛋白相对表达量显著降低(P<
        0.01)。与TE-1/EC-1瓜蒂水提物组比较,TE-1/EC-1瓜蒂醇提物组细胞克隆形成率显著下降(P<0.05);G2期细胞率显著升高(P<
        0.05);EGFR、PKC-α蛋白相对表达量显著降低(P<0.01);TE-1瓜蒂醇提物组早、晚期细胞凋亡率显著降低(P<0.05);EC-1瓜蒂
        醇提物组早、晚期细胞凋亡率显著升高(P<0.05)。结论:瓜蒂水提物和醇提物可影响TE-1、EC-1细胞增殖、迁移、克隆形成的能
        力,促进细胞凋亡,其作用机制可能与下调EGFR、PKC-α蛋白有关。

        ABSTRACT    OBJECTIVE:To study the effects and mechanism of water extract and ethanol extract of Muskmelon Pedicel on the
        proliferation,migration and cloning formation of esophageal carcinoma TE-1 and EC-1 cells. METHODS:TE-1 and EC-1 cells
        were cultured in vitro,and were treated with 0,1.562 5,3.125,6.25,12.5,25,50,100,200 μg/mL of water extract and ethanol
        extract of Muskmelon Pedicel(calulated by extract powder). MTT assay was used to detect the growth inhibitory rate of TE-1 and
        EC-1 cells,and calculate IC50 of them. TE-1 and EC-1 cells were divided into TE-1/EC-1 blank group,TE-1/EC-1 Muskmelon
        Pedicel water extract group(IC50 as drug concentration),and TE-1/EC-1 Muskmelon Pedicel ethanol extract group(IC50 as drug
        concentration). The proliferation and migration of cells in each group were detected by real-time unlabeled cell analysis(RTCA),
        and cell proliferation and migration curves were drawn. The morphological changes of cells were observed under microscope;soft
        agarose colony forming test was used to analyze the change of colony forming ability of cells in each group,and the colony
        forming rate was calculated;cell cycle and apoptosis rate of cells in each group were detected by flow cytometry;Western blotting
        assay was used to detect the relative expression of EGFR and PKC-α in cells in each group. RESULTS:IC50 of water extract of
        Muskmelon Pedicel were 49.24,76.38 μg/mL respectively for TE-1 and EC-1 cells. Those of ethanol extract of Muskmelon Pedicel
        were 9.08,14.53 μ g/mL respectively for TE-1 and EC-1 cells. The inhibition effect of water extract and ethanol extract of
                                                            Muskmelon Pedicel on the cell proliferation were within 30 h.
