摘要
目的 了解基质分解素-1(MMP_3)基因在胃癌组织的表达水平。方法 43例胃癌患者胃镜下取癌组织及正常胃粘膜,提取组织总RNA,用逆转录共扩增定量PCR方法测定MMP_3基因表达水平。结果 胃癌组织MMP_3,基因表达水平(2.02±0.34)明显高于正常胃粘膜组织(0.63±0.10,P<0.01),局部淋巴结受累者MMP_3基因表达水平(2.46±0.39)明显高于局部淋巴结未受累者(1.60±0.30,P<0.01)。结论 基质分解素-1在胃癌的浸润、转移中可能起重要作用。
Objective To investigate expression of stromelysin-1 ( MMP3) gene in tissues of gastric carcinoma. Methods 43 patients with stomach carcinoma were selected in this study. Cancerous tissue and normal gastric mucosa tissue were obtained under gastroscopy. Total RNA was isolated and expression of MMP3 gene was measured by reverse transription polymerase chain reac-tion( RT-PCR). Results Expression of MMP3 gene was stronger in gastric cancerous tissue(2. 02 ?
