摘要:

 目的: 探讨韭籽多糖对人食管癌EC9706细胞增殖和凋亡的影响。 方法:应用流式细胞仪、Hoechst33258染色、透射电镜、DNA凝胶电泳等技术检测、观察韭籽多糖对食管癌EC9706细胞增殖和凋亡的影响。结果:40 μg/mL的韭籽多糖可明显抑制食管癌EC9706细胞增殖 (P<0.05),作用48 h后,可诱导食管癌EC9706细胞出现明显凋亡特征性的形态结构和DNA条带。结论:韭籽多糖可抑制人食管癌EC9706细胞增殖,诱导肿瘤细胞凋亡。

Abstract:

 OBJECTIVE: To investigate the effects of Leek seed polysaccharide on the proliferation and apoptosis of human esophagus cancer cell EC9706. METHODS:Flow cytometry,Hoechst33258 staining,transmission electron microscope and DNA gel electrophoresis were used. RESULTS:Proliferation of EC9706 cells was significantly inhibited by Leek seed polysaccharide at the dose of 40 μg/mL(P<0.05). Moreover,after 48 hour of treatment by Leek seed polysaccharide,obvious characteristic features of apoptosis and DNA ladder were also induced. CONCLUSION: Leek seed polysaccharide could inhibit EC9706 cell proliferation and induce its apoptosis.

Key words:  Leek seed polysaccharide, human esophagus cancer cell EC9706, proliferation, apoptosis
