Role Reversal: A Pro-metastatic Function of E-Cadherin.

Carcinoma cells often acquire mobility and invasiveness by undergoing epithelial-to-mesenchymal transition, and yet most metastatic lesions remain epithelial in nature. Recently, in Nature, Padmanaban et al. (2019) demonstrated that the quintessential epithelial marker E-cadherin promotes metastasis of invasive ductal breast carcinoma by enhancing the survival of tumor cells.
