摘要: 目的: 观察三叶青黄酮对SGC-7901 人胃癌细胞凋亡的诱导作用, 初步探讨其可能的机制。方法: 体外培养SGC-7901 人胃癌细胞, 并用MTT 法检测三叶青黄酮对肿瘤细胞生长的抑制作用, 流式细胞仪分析细胞周期, 光镜和电镜观察细胞形态改变,酶谱分析基质金属蛋白酶-2(MMP-2)蛋白的表达改变。结果: 三叶青黄酮能显著地抑制SGC-7901 细胞的生长, 并且具有浓度依赖性, 且细胞有明显的凋亡特征性改变, 并能降低细胞上清液中MMP-2 的含量。结论: 三叶青黄酮具有抗肿瘤细胞增殖和诱导凋亡的作用, 有潜在的抗肿瘤价值, 值得进一步研究。

Abstract: AIM: To study the effect of Tetrastigma hemsleyanum Diels et Gilg flavone (TDGF)on inducing SGC-7901 tumor cell apoptosis and to approach its mechanism.Methods: MTT assay was carried out to evaluate TDGF's activity;cell morphology change was monitored through optical microscope and electron microscope; cell apoptosis was detected by flow cytometry with Annexin Ⅴ PI staining assay;the concentration of MMP-2 protein in the supernatant of tumor cell culture was also measured by zymography essay.Results: Tetrastigma hemsleyanum Diels et Gilg flavone inhibited SGC-7901 cell proliferation in a concentration-related manner, and SGC-7901 cells had the characteristic changes of apoptosis in morphology.Tetrastigma hemsleyanum Diels et Gilg flavone could also down-regulate the concentration of MMP-2.Conclusion: Tetrastigma hemsleyanum Diels et Gilg flavone promotes tumor cell apoptosis significantly, which may be related to down-regulating the expression of MMP-2.So TDGF is a new promising anti-tumor TCM drug.

Key words: Tetrastigma hemsleyanum Diels et Gilg flavone, tumor, apoptosis, matrix metalloproteinase-2
