Abnormal beta-catenin expression in oral cancer with no gene mutation: correlation with expression of cyclin D1 and epidermal growth factor receptor, Ki-67 labeling index, and clinicopathological features.

Abstract excerpt

Beta-Catenin not only acts as a regulator of E-cadherin-mediated cell-cell adhesion but also plays an important role in Wnt signaling. To assess the prevalence of Wnt signaling, we examined beta-catenin mutation and its immunohistochemical protein expression in oral cancers. The results were linked with expression of cyclin D1, one of the target genes of Wnt signaling, expression of epidermal growth factor...
