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.
