摘要: 目的 研究藏药余甘子鞣质部位的体外抗肿瘤作用机制。方法 余甘子鞣质部位40 、80 、160 μg·mL-1作用于人肿瘤A549及BEL-7402细胞48 h, MTT法测定剂量反应曲线;倒置相差显微镜下观察两种细胞形态学的变化;流式细胞术测定细胞周期及凋亡的情况。结果 不同浓度的余甘子鞣质部位作用48 h对A549和BEL-7402细胞均表现明显的细胞毒作用;倒置镜下可见加药组细胞生长受到明显抑制,细胞收缩变小;流式细胞术测定发现余甘子鞣质部位具有显著的诱导细胞早期凋亡和G2/M期阻滞作用。结论 余甘子鞣质部位可通过诱导肿瘤细胞凋亡和对细胞周期阻滞而发挥其体外抗肿瘤作用。

Abstract: Objective To investigate the mechanism of antitumor activity of tannin part of Tibetan medicine Phyllanthi Fructus on human tumor cells in vitro. Methods The human tumor A549 cells and BEL-7402 cells were treated with tannin part of Tibetan medicine Phyllanthi Fructus with 40, 80 and 160 μg·mL-1 for 48 h. They were detected by MTT assay.Morphology changes in cells were examined under the inverted phase contrast microscope. Cell cycle and apoptosis in both cells were determined by flow cytometry. Results MTT assay showed a significant cytotoxicity on A549 cells and BEL-7402 cells in different concentration of tannin part of Tibetan medicine Phyllanthi Fructus for 48 h. Significant growth inhibition and cells shrinkage were observed in cells that received treatment. Significant cells early apoptosis and G2/M phase block were induced by tannin part of Tibetan medicine Phyllanthi Fructus. Conclusion Tannin part of Tibetan medicine Phyllanthi Fructus showed antitumor activity in vitro. Inducing tumor apoptosis and cell cycle block contribute to this activity.

Key words: tannin part of Phyllanthi Fructus, antitumor, apoptosis, cell cycle
