To investigate the expressions of Wnt-1, beta-catenin and adenomatous polyposis coli (APC) in oral squamous cell carcinoma (OSCC). Surgical specimens from 66 OSCC patients were examined for Wnt-1, beta-catenin, APC and MIB-1 expressions by immunohistochemical staining. Among all the 37 cases of well differentiated OSCCs, there were 30, 25 and 31 cases of high expressions of Wnt-1, APC and beta-catenin, respectively, 7, 12 and 6 cases of low expressions. Among all the 29 cases of moderate and poor differentiated OSCCs, there were 6, 9 and 11 cases of high expressions of Wnt-1, APC and beta-catenin respectively, 23, 20 and 18 cases of low expressions. Among all the 66 cases of OSCCs, there were 32 cases of high expressions of MIB-1 and 34 cases of low expressions. Expressions of Wnt-1, beta-catenin and APC showed significant difference in different differentiation of OSCC. Wnt-1, beta-catenin and APC expressions were related to the differentiation of OSCC.
