Cadherin-11 increases tumor cell proliferation and metastatic potential via Wnt pathway activation.

ABSTRACT: During epithelial-mesenchymal transition (EMT) in cancer progression, tumor cells switch cadherin profile from E-cadherin to cadherin-11 (CDH11), which is accompanied by increased invasiveness and metastatic activity. However, the mechanism through which CDH11 may affect tumor growth and metastasis remains elusive. Here, we report that CDH11 was highly expressed in multiple human tumors and was localized on the membrane, in the cytoplasm and, surprisingly, also in the nucleus. Interestingly, β-catenin remained bound to carboxy-terminal fragments (CTFs) of CDH11, the products of CDH11 cleavage, and co-localized with CTFs in the nucleus in the majority of breast cancer samples. Binding of β-catenin to CTFs preserved β-catenin activity, whereas inhibiting CDH11 cleavage led to β-catenin phosp
