摘要: 目的:探讨五倍子酸(GA)对人胃癌SGC-7901细胞转移的影响,阐明其作用机制。方法:培养人胃癌SGC-7901细胞,将其分为对照组及3.125、6.250、12.500、25.000、50.000和100.000 mg·L-1GA组。MTT法检测各组SGC-7901细胞增殖抑制率,细胞划痕实验检测各组细胞转移能力,免疫细胞化学法检测各组SGC-7901细胞中血管内皮生长因子(VEGF)表达水平。结果:与对照组比较,不同剂量GA组SGC-7901细胞增殖抑制率明显升高,并呈剂量依赖性(F=59.451,P<0.01)。与对照组比较,不同剂量GA组SGC-7901细胞的划痕愈合率明显降低(P<0.01),12.500和25.000 mg·L-1 GA组细胞中VEGF蛋白表达水平明显降低(P<0.05)。结论:GA通过抑制人胃癌SGC-7901细胞中VEGF蛋白的表达来抑制SGC-7901细胞增殖及迁移。

Abstract: Objective: To study the influence of gallic acid (GA) on the migration of human gastric carcinoma SGC-7901 cells, and to explore its mechanism.Methods: The human gastric carcinoma SGC-7901 cells were cultured and divided into control group and 3.125, 6.250, 12.500, 25.000, 50.000,100.000 mg·L-1 GA groups. The inhibitory rates of proliferation of SGC-7901 cells in various groups were examined by MTT assay; the migration abilities of SGC-7901 cells in various groups were measured with scratch assay; the expression levels of vascular of endothelial growth factor (VEGF) in various groups were detected by immunocytochemistry.Results: Compared with control group, the inhibitory rates of proliferation of SGC-7901 cells in different doses of GA groups were significantly increased in a dose-dependent manner(F=59.451,P<0.01). Compared with control group, the wound healing rates in different doses of GA groups were significantly decreased (P<0.01). Compared with control group, the expression levels of VEGF protein in 12.500 and 25.000 mg·L-1 GA groups were decreased (P<0.05).Conclusion: GA could inhibit the proliferation and migration of SGC-7901 cells through down-regulating the expression levels of VEGF protein.

Key words: cell migration, vascular endothelial growth factor, gallic acid, SGC-7901 cells
