摘要: 目的:检测基质金属蛋白酶2(MMP-2)、PTEN基因在大肠癌组织中的表达,并研究其临床病理意义。 方法:采用逆转录聚合酶链反应(RT-PCR)检测MMP-2及PTEN在40例大肠癌组织中的表达。 结果:①Dukes A、B期大肠癌组织与对照组正常大肠粘膜组织比较,MMP-2、PTEN的表达差异均有显著性(P<0.01);DukesC、D期与A、B期比较,MMP-2及PTEN的表达差异均有显著性(P<0.05);②MMP-2及PTEN在高、中分化腺癌和低分化腺癌阳性表达率差异均有显著性(P<0.05);③MMP-2及PTEN在有淋巴结转移组和无淋巴结转移组检出阳性率差异均有显著性(P<0.05)。 结论:MMP-2及PTEN的表达与大肠癌临床病理特征和生物学行为有关联,MMP-2及PTEN基因是大肠癌细胞增生活跃的重要影响因素。

Abstract: Objective To explore the expressions of tumor-related genes (MMP-2 and PTEN) in colorectal carcinoma tissues and their clinic pathological significances. Methods The expressions of MMP-2 and PTEN in 40 patients with colorectal carcinoma were investigated by RT-PCR. Results ①There existed significant differences of the expressions of MMP-2 and PTEN between normal control and Dukes A,B (P<0.01); as well as the expressions of MMP-2 and PTEN between Dukes C,D and Dukes A,B(P<0.05); ②There existed significant differences of the expression rates of MMP-2 and PTEN between the high or middle differentiation grade of the carcinoma and the low differentiation grade (P<0.05);③There existed significant differences of the expression rates of MMP-2 and PTEN between the patients with lymph metastasis and those without lymph metastasis (P<0.05). Conclusion The expressions of MMP-2 and PTEN have close relationship with the pathology of colorectal carcinoma and their own biology behaviors. Both MMP-2 and PTEN play important roles in distincting hyperplasia of colorectal carcinoma.
