大蒜素对胃癌细胞株及裸鼠移植瘤的抑制作用

Inhibitory Effect of Garlicin on Gastric Cancer Cells and Nude Mice Tumor Xenograft

  • 摘要: 目的 观察大蒜素对胃癌细胞株及移植瘤的作用, 初步探讨抗癌机制。方法 采用MTT法观察不同质量浓度及作用不同时间大蒜素对胃癌 SGC- 790 1及 MGC- 80 3细胞的影响 ;流式细胞术分析 1 0 0 mg&#8226; L-1大蒜素分别作用 4h和 8h后两种肿瘤细胞增殖周期的变化 ;荷胃癌SGC- 790 1裸鼠模型随机分成 4组, 每组 4只, 分别于荷瘤 7d和 1 4d用 2 0 g/L的大蒜素 0 .1 m L和PBS0 .1 m L对瘤体进行局部注射治疗, 每隔 2 d一次, 共 3次, 观察瘤体增殖及裸鼠生存状况的变化。结果 不同质量浓度梯度大蒜素对两种肿瘤细胞皆有一定的杀伤, 大蒜素质量浓度为 80 0 mg&#8226; L-1及 1 0 0 0 mg&#8226;L-1时, 对 SGC- 790 1细胞的抑制率分别为 65.5%, 68.6% (P<0 .0 1, vs5- FU)。大蒜素对 MGC- 80 3细胞的抑制作用较明显, 质量浓度为 40 0 mg&#8226;L-1,80 0 mg&#8226; L-1及 1 0 0 0 mg&#8226;L-1时, 抑制率分别为 67.5%, 75.3%和 79.5% .

     

    Abstract: Objective To study the anticarcinogen mechanism of garlicin after observation of the effect of garlicin on gastric cancer cells. Methods Cultural cell lines of gastric cancer SGC-7901 and MGC-803 were used as the target cells to observe the effect of garlicin of different concertritions with different culture time on these cell lines by MTT assay.Two kinds of gastrical cancer cells with 10% bovine serum and 100mg&#8226;L\+ -1 garlicin were cultured,and their changs of cell cycles after 4 and 8 hours were meas...
