摘　　要：目的探讨RNA干扰EMS1基因表达对人胃癌MGC803细胞增殖和迁移的影响。方法为检测下调EMS1基因表达后MGC803细胞功能的变化,运用平皿集落形成实验检测其增殖能力;流式细胞仪分析细胞周期和凋亡;Transwell迁移和侵袭实验观察细胞迁移和侵袭能力的变化。结果下调MGC803细胞中EMS1基因表达后,MGC803细胞增殖、迁移和侵袭能力受到抑制,与对照组相比差异有显著性(P<0.05),而对细胞周期和凋亡无明显影响。结论 RNA干扰EMS1基因可抑制胃癌MGC803细胞的增殖和迁移侵袭能力。Purpose To explore the effect of EMSI-siRNA on the growth, invasion and migration of human gastric cancer cell line MGC803. Methods It used the Colony formation assay to determine the abilities of proliferation, and flow cytometry analysis to asses cell cycle distribution and apoptosis, transwell invasion and migration experiment to determine the ability of cell invasion and migration after knockdown the expression of EMS1 in MGC803. Results These results suggested that EMS1 gene down-regulated have no affect on cell cycle and cell apoptosis, but the ability of colony formation depressed and migration lowerd obviously （P 〈 0. 05）. Conclusion The results shows EMS1 gene is related to proliferation and migration of tumor.
