摘要: 目的:研究槲寄生凝集素对人结肠癌HT-29细胞增殖和凋亡的影响。方法:采用MTT 法观察槲寄生凝集素对体外培养的人结肠癌HT-29 细胞增殖的影响, 运用基因组DNA 电泳观察凋亡特征性“梯状”条带及原位末端标记法检测槲寄生凝集素诱导HT-29 细胞凋亡。结果:槲寄生凝集素对体外培养的人结肠癌HT-29 细胞抑制作用表现出时间和剂量依赖性。基因组DNA 琼脂糖凝胶电泳显示槲寄生凝集素作用于HT-29 细胞后出现凋亡细胞特有的DNA 阶梯状条带。原位末端标记法检测显示槲寄生凝集素可明显诱导HT-29 细胞的凋亡。结论:槲寄生凝集素可抑制人结肠癌HT-29 细胞生长并诱导其凋亡。

Abstract: AIM: To study the effect of mistletoe lectins on cell proliferation and apoptosis in HT-29 human colon cancer cell.METHODS: The effect of mistletoe lectins on cell viability in HT-29 cell was evaluated by MTT assay.Cell apoptosis was observed by DNA ladder analysis and Tunel.RESULTS: Mistletoe lectins (eg., 1-4 mg L) inhibited cell growth in a dose and time dependent way in HT-29 cells.HT-29 cells apoptosis can be induced when exposed to mistletoe lectins(eg., 1-4 mg L).CONCLUSION: Mistletoe lectins can inhibits proliferation and induces apoptosis in HT-29 cells in vitro.

Key words: mistletoe lectins, colon cancer, apoptosis
