大黄素对人胃癌BGC-823细胞体外增殖和迁移的影响

目的 探讨大黄素对人胃癌BGC-823细胞增殖和迁移的影响。 方法 采用四甲基偶氮唑盐（MTT）比色法测定不同浓度大黄素对体外培养人胃癌BGC-823细胞增殖的影响；采用流式细胞术测定大黄素对人胃癌BGC-823细胞的细胞周期影响；采用划痕损伤实验测定大黄素对人胃癌BGC-823细胞迁移的影响。 结果 MTT法显示，大黄素能抑制人胃癌BGC-823细胞増殖，呈现浓度依赖性；流式细胞术显示，人胃癌BGC-823细胞的细胞周期主要停滞在G₀/G₁期；划痕损伤实验表明，人胃癌BGC-823细胞迁移受到明显的抑制。 结论 大黄素对人胃癌BGC-823细胞的增殖和迁移具有明显的抑制作用，且呈浓度依赖性，并可使人胃癌BGC-823细胞增殖周期停滞于G₀/G₁期。

Effects of aloe-emodin on proliferation and migration of human gastric cancer cell line BGC-823

Objective To investigate the effect of aloe-emodin on proliferation and migration of human gastric cancer cell line BGC-823. Methods The effects of aloe-emodin on cell proliferation,cell cycle stage and migration ability of BGC-823 cells were observed.The proliferation level was measured by MTT method, cell cycle stage was detected with flow cytometry and migration ability was tested by wound healing assay. Results MTT assay showed the inhibitory effect of aloe-emodin on proliferation of BGC-823 cells was dose-dependent; Treatment of BGC-823 cells with aloe-emodin resulted in cell cycle arrest at G₀/G₁ phase by flow cytometry analysis; The migration velocity of BGC-823 cells was obviously inhibited as shown in wound healing assay. Conclusion The inhibitory effect of aloe-emodin on proliferation and migration of BGC-823 cells was dose-dependent, as well as the cell cycle was arrested at G₀/G₁ phase, which offers the clue for further understanding the inhibition mechanism of aloe-emodin on human gastric cancer cell line BGC-823.
