News and views on EMT Fra-1 controls EMT in mammary epithelial cells

Abstract

Epithelial-to-mesenchymal transition (EMT), a process critical for breast cancer cell dissemination, engages the Fos-related antigen 1 (Fra-1) transcription factor. Molecular and cellular analyses revealed an evolutionary conservation of Fra-1 functions in EMT of mouse and human mammary cells, establishing a solid basis for preclinical studies in genetically engineered mouse models.
