Abstract

N-cadherin is not typically expressed by epithelial cells. However, it is detected in breast cancers and increases tumor cell migration and invasion in vitro. To explore its misexpression, we generated transgenic mice with N-cadherin in the mammary epithelium. Mammary glands appeared normal and no tumors arose spontaneously. To investigate N-cadherin misexpression in mammary tumors, neu was overexpressed through breeding. Tumors developed in +/neu and N-cadherin/neu mice, although few tumors in bitransgenic mice expressed N-cadherin, and they did not differ from N-cadherin-negative tumors.
