| 摘 要： | 目的：分析S100A3在胃癌中表达情况及临床意义。方法采用逆转录-聚合酶链反应、蛋白质印迹和组织微阵列分析90例胃癌组织及正常胃组织标本和胃癌细胞系中S100A3基因、蛋白表达水平及组学定位。结果胃癌组织S100A3基因表达水平高于正常胃组织2.5倍，S100A3的上调表达与肿瘤分化程度、TNM分期相关，胃癌细胞S100A3基因呈上调表达。胃癌组织中S100A3蛋白表达水平强阳性表达（74.7%）。结论 S100A3上调表达与胃癌分化程度及TNM分期密切相关。

Expressions and clinical signiifcance of S100A3 in gastric cancer |

| Abstract: | ObjectiveTo explore the expression and clinical significance of S100A3 within gastric cancer. MethodsCombined with analysis of RT-PCR, Western blot and Tissue microarray(TMA), the mRNA and protein expression levels of S100A3 in normal and malignant stomach tissues and cell lines were systematically investigated. ResultsThe mean expression levels of S100A3 in gastric cancer tissues were 2.5 times as high as in adjacent non-tumorous tissues. S100A3 expression was correlated with tumor differentiation and TNM stage of gastric cancer. S100A3 was overexpression in gastric cancer cell lines. The mean expression levels of S100A3 protein in gastri cancer were higher. ConclusionOverexpressed S100A3 may be associated with the differentiation and progression of gastric cancer. |
