摘要： 目的:比较视网膜母细胞瘤RB1-诱导卷曲蛋白1(RB1CC1)在人和小鼠正常口腔黏膜、上皮异常增生组织及口腔鳞状细胞癌中的表达,并探讨其在口腔癌发生发展过程中的作用。方法:采用免疫组化和RT-PCR检测人及小鼠在正常口腔黏膜、上皮异常增生、高分化鳞癌原发灶组织中RB1CC1蛋白及基因的表达情况。结果:RB1CC1蛋白在人上皮异常增生组、高分化鳞癌组的阳性表达高于正常组(P<0.05);RB1CC1蛋白在鼠正常组、异常增生组、高分化鳞癌组阳性表达逐渐增加,差异均有统计学意义(P<0.05)。人RB1CC1 mRNA的表达量在异常增生组与高分化鳞癌组无明显差异,正常口腔黏膜组均高于异常增生组与高分化鳞癌组(P＜0.05);小鼠RB1CC1 mRNA的表达量在正常口腔黏膜组与异常增生组、高分化鳞癌组差别无统计学意义。结论:RB1CC1表达在人和小鼠相似, RB1CC1可能参与了口腔鳞癌的早期癌变过程。

Abstract: Objective: To compare the expression of RB1-inducible coiled-coil 1 (RB1CC1) in normal oral mucosa, dysplasia and oral squamous cell carcinoma (OSCC) of human and mouse model, and explore the role of RB1CC1 in the occurrence and development of OSCC. Methods: Immunohistochemical and reverse transcription-polymerase chain reaction method were used to detect the expression of RB1CC1 in 10 cases of human normal oral mucosa, 20 cases of dysplasia and 20 cases of well differentiated OSCC as well as 7 cases of mouse normal oral mucosa, 13 cases of dysplasia and 13 cases of OSCC, respectively. Results: In human, the positive expression rates of RB1CC1 in dysplasia and well differentiated squamous cell carcinoma group were higher than that in normal oral mucosa group (P<0.05). In mouse, the positive expression rate of RB1CC1 gradually increased from normal to carcinoma group (P<0.05). By contrast, in human, the gene expression of RB1CC1 in normal oral mucosa was higher than dysplasia and OSCC group (P<0.05), but not significantly different in dysplasia and well differentiated OSCC group. Conclusion: The expression of RB1CC1 was similar in the same pathological stages of between human and mouse, and may play an important role in early carcinogenesis of OSCC.
