trastuzumab

The HER2 (or c-erbB2) proto-oncogene encodes a transmembrane receptor protein of 185 kDa which is structurally related to the epidermal growth factor receptor. Trastuzumab has been shown to inhibit the proliferation of human tumor cells that overexpress HER2. Trastuzumab is a mediator of antibody-dependent cellular cytotoxicity (ADCC). In vitro, trastuzumab-mediated ADCC has been shown to be preferentially exerted on HER2 overexpressing cancer cells compared with cancer cells that do not overexpress HER2. Trastuzumab is indicated* for treatment of breast cancer and gastric cancer.
