摘　　要：目的研究MMP-2、MMP-3和MMP-9在胃癌细胞转移中作用,进一步探讨MMP-2、MMP-3和MMP-9的临床意义。方法体外培养SGC-7901胃癌细胞和GES-1胃上皮细胞,划痕损伤实验模型和Transwell小室模型法检测这2种细胞的迁移,ELISA法检测培养液中MMP-2、MMP-3和MMP-9的含量。免疫组化检测胃癌、胃炎患者和正常人MMP-3的阳性率,ELISA检测血清中MMP-2、MMP-3和MMP-9的含量。结果细胞划痕实验和Transwell实验均显示,SGC-7901细胞迁移能力强于GES-1;SGC-7901分泌的3种蛋白含量均高于GES-1;免疫组化结果显示,胃癌患者MMP-3的阳性率84.4%,高于胃炎患者和正常人。其血清中MMP-2、MMP-3和MMP-9也明显高于胃炎患者和正常人。结论胃癌细胞的转移能力与MMP-2、MMP-3和MMP-9的含量相关,3种蛋白可用于胃癌的早期诊断。Objecitive The research was in order to explore the roles of MMP-2,MMP-3 and MMP 9 which played in the gastric cancer cell metastasis,and make a further study of the clinical signifance.Methods Both SGC-7901 and GES-1 were cultured in vivo.The migra-tion were examined by Wound-healing and the Transwell assay.The expression of MMP-2,MMP-3 and MMP 9 in the medium were detected by ELISA.The positive rate of MMP-3 in the gastric cancer,gastritis and normal was used the IHC,and the serum of MMP-2,MMP-3 and MMP-9 were also examined by ELISA.Results Both Wound-healing and Transwell assay showed that the migration of SGC-7901 cells was more quicker than the GES-1.Comparing to GES-1,the MMP-2,MMP-3 and MMP-9 were higher in the SGC-7901.The immunohistochemical results showed that the positive rate of MMP-3 in the gastric cancer patients was 84.4%,it was higher than the latter.The serum levels of MMP-2 MMP-3 and MMP-9 were also significantly higher than others.Conclusion The migration of gastric cancer cells was depended on the MMP-2,MMP-3 and MMP-9.The 3 proteins can be used for the diagnosis of gastric cancer patients,and it also avail to make the judgment the prognosis of patients with gastric carcinoma.
