目的:探讨结肠癌组织中SLP-2蛋白的表达情况及SLP-2基因对结肠癌细胞HCT-116侵袭、迁移力的影响。方法:采用免疫组化法检测50对结肠癌及正常结肠黏膜组织中SLP-2蛋白的表达,分析患者临床病理特征与SLP-2蛋白表达的关系。设计合成SLP-2 siRNA,转染结肠癌HCT-116细胞,Transwell法及Matrigel基质实验检测转染SLP-2 siRNA对HCT-116细胞侵袭、迁移力的影响,RT-PCR及Western blot 检测转染48 h后HCT-116细胞中SLP-2 mRNA及蛋白的表达情况。结果:正常结肠及结肠癌组织中SLP-2蛋白的高表达率比较,差异有统计学意义(χ2配对=23.188,P<0.001)。 SLP-2蛋白表达与结肠癌TNM分期(χ2=10.474,P=0.001)及淋巴结转移(χ2=19.647,P<0.001)有关。 SLP-2 siRNA转染组细胞迁移力、侵袭力、SLP-2 mRNA及蛋白表达水平均低于阴性对照组和空白对照组(P均<0.05)。结论:结肠癌组织中SLP-2高表达;SLP-2可能通过促进结肠癌细胞的侵袭、迁移能力,参与结肠癌的转移。

To investigate SLP-2 expression in colorectal cancer tissue and its influence on HCT-116 cell's migra-tion and invasion .Methods:Immunohistochemistry was used to detect the expression of SLP-2 protein in 50 normal color-ectal tissue and colorectal cancer tissue .Then the relationship between the expression of SLP-2 protein and the clinical pathological characteristics of the 50 colorectal cancer cases was analyzed .SLP-2 siRNA was transfected into colorectal cancer cell line HCT-116 .The SLP-2 mRNA and protein expression in HCT-116 cells were detected using RT-PCR and Western blot .The cell migration and invasion ability was detected by Transwell test and Matrigel invasion test .Results:The high SLP-2 expression rate in coloretal cancer tissue was higher than that of the adjacent normal colorectal tissue (χ2paired =23.188,P<0.001).The expression of SLP-2 in coloretal cancer tissue was associated with TNM staging (χ2 =10.474,P=0.001) and lymph nodes metastasis (χ2 =19.647,P<0.001).After interfering with SLP-2 siRNA, the mi-gration and invasion ability of HCT-116 cell decreased , and the exprssion of SLP-2 mRNA and protein decreased ( P<0.05).Conclusion:SLP-2 protein shows up-regulation in colorectal cancer , and it may promote cell metastasis through promoting migration and invasion ability .
