E-cadherin and its adhesion complex play an essential role in the adhesion
of breast cancer cells and tissues. Members of the complex, such as beta -c
atenin, act as regulators on cell adhesion, and are involved in cell signal
ling and transcription regulation. The adhesion complex is a known structur
e in the control of tumour progression and metastasis. Recent years have se
en a rapid expansion in the understanding of the biology and clinical relev
ance of the complex in breast cancer. The current article summarises recent
progresses in the molecular/cellular biology of E-cadherin and its complex
and the clinical, diagnostic, prognostic, and therapeutic value of this co
mplex in breast cancer. (C) 2001 Elsevier Science Ltd. All rights reserved.
