摘要:

目的研究血管细胞黏附分子-1(VCAM-1)在口腔鳞状细胞癌(OSCC)中的表达与定位及其临床意义。方法应用分子原位杂交和免疫组化方法对48例OSCC组织和10例正常口腔黏膜组织中VCAM-1 mRNA和VCAM-1蛋白质的表达和定位进行检测,比较VCAM-1在不同口腔组织中的表达率及其与临床指标的关系。结果VCAM-1蛋白定位于肿瘤细胞胞浆和胞膜,VCAM-1 mRNA定位于肿瘤细胞胞浆。VCAM-1 mRNA和VCAM-1蛋白在OSCC中的表达率均显著高于正常口腔黏膜组织(P<0.01),VCAM-1 mRNA表达与VCAM-1蛋白表达呈正相关(P<0.01);OSCC中淋巴结转移者VCAM-1蛋白的表达显著高于无淋巴结转移者(P<0.01)。结论OSCC中VCAM-1基因的高表达可能与肿瘤的浸润和转移有关。

Abstract:

Objective To study the expression and the location of vascular cell adhesion molecule-1(VCAM-1) gene and its clinical significance in human oral squamous cell carcinoma(OSCC). Methods In situ hybridization, PV-9000 polymer detection system for immunohistochemical staining was used to detect the expression and the location of VCAM-1 mRNA and VCAM-1 protein in 48 cases of OSCC and 10 cases of normal controls. Statistical analysis was performed using chi-square test in SPSS 13.0. Results VCAM-1 protein was mainly expressed in tumor cell cytoplasm and membrane, VCAM-1 mRNA was mainly expressed in tumor cell cytoplasm. The expression rate of VCAM-1 mRNA and VCAM-1 protein was significantly higher in OSCC than that in normal oral mucosa(P<0.01). The expression of VCAM-1 mRNA was positively correlated with that of VCAM-1 protein(P<0.01). In the clinicopathologic factors, lymph node metastasis and depth of infiltration were closely correlated with VCAM-1 expression (P<0.01). The expression of VCAM-1 was significantly higher in tumor with lymph node metastasis than in tumor without lymph node metastasis(P<0.01). Conclusion Overexpression of VCAM-1 gene in OSCC may play a potential role in the development of OSCC. The overexpression of VCAM-1 gene in OSCC may be related to the tumor infiltration and metastasis.
