title: ErbB2 activation and signal transduction in normal and malignant mammary cells.
abstract: One of the first consistent genetic alterations found in human breast tumors was amplification of the erbB-2 gene leading to overexpression of the protein. ErbB2 is a member of the ErbB/type I family of receptor tyrosine kinases which also includes epidermal growth factor receptor, ErbB3 and ErbB4. The role of ErbB2 in the biology of the mammary gland as well as in breast cancer development is under intense investigation. In clinical studies, the ErbB2 protein level has been examined for its utility in predicting patient prognosis and response to treatment. The ErbB2 receptor is also being tested as a target for tumor directed therapies.
