摘要
目的探讨人叉头框C2(FOXC2)和Vimentin蛋白在胃癌组织中的表达和意义。方法采用免疫组化S-P法检测65例胃癌组织及20例正常胃黏膜中FOXC2和Vimentin的表达,分析两种蛋白与胃癌临床特征之间的关系及两者的相关性。结果胃癌组织中FOXC2和Vimentin均呈现高表达,FOXC2和Vimentin在胃癌组织中的阳性表达率分别为41.53%和35.38%。FOXC2在中晚期胃癌的表达率为58.60%,明显高于早期胃癌表达率27.78%(P=0.012);FOXC2在有淋巴结转移组中的表达率为55.88%,明显高于无淋巴结转移组表达率29.03%(P=0.018)。Vimentin在中晚期胃癌的表达率为51.72%,明显高于早期胃癌表达率22.22%(P=0.013);在有淋巴结转移组的表达率为41.20%,高于无淋巴结转移组表达率14.80%(P=0.010)。胃癌组织中FOXC2与Vimentin的表达呈正相关(P=0.037)。结论 FOXC2和Vimentin可能参与了上皮细胞间质转化过程,在胃癌转移中扮演重要角色。
Objective To investigate the expression and effect of FOXC2 （forkhead box C2） and Vimentin in gastric carcinoma tissues .Methods To detect the protein expression of FOXC2 and Vimentin in 20 normal gastric tissues and 65 gastric carcinoma tissues with immunochemistry .Results FOXC2 and Vimentin were highly expressed in all gastric carcinoma tissues .In all gastric carcinoma cases ,the FOXC2 expression rate was 41 .53% ,the rate of Vimentin was 35 .38% .The average expression rates of FOXC2 and Vimentin in TNM （ Ⅲ ＋ Ⅳ ） group were significantly higher than those in TNM （Ⅰ ＋ Ⅱ ） group ,respectively （58 .60% vs .27 .78% ,P=0 .012 ;55 .88% vs .29 .03% ,P=0 .018） .The expression rates of FOXC2 and Vimentin in lymph node transfer group were statistically higher than those in no lymph node transfer group （51 .72% vs .22 .22% ,P=0 .013;41 .20% vs . 14 .80% ,P=0 .010） .The correlation between FOXC2 and Vimentin was positive （P= 0 .037） .Conclusion It is possible that FOXC2 and Vimentin are involved in the transformation of epithelial cells into the mesenchymal cells .And they may play an impor-tant role in the metastasis of gastric carcinoma .
