ABSTRACT
Objective:To investigate ?-catenin expression during check pouch carcinogenesis in golden hamster.Methods:Expression of ?-catenin was examined with immunohistochemical SABC method in 23 cases of check normal buccal epithelium of golden hamster,22 of hyperplasitic epithelium,22 of dysplastic epithelium,29 of squamous cell carcinoma.Results:Normal buccal epithelium showed strong pericellular staining in the basal,suprabasal and prickle cell layers.Positive rates(%) of ?-catenin in normal buccal epithelium,hyperplastic epithelium,dysplastic epithelium and squamous cell carcinoma were 100,100,77.3 and 41.4 respectively.Conclusion: The decreased expression of ?-catenin may be related to the carcinogenesis of golden hamster check pouch.
