Her2/neu is a tyrosine kinase receptor which stimulates cell growth. The receptor is overexpressed in about 20% of breast cancers. Her2/neu expression is an indicator of poor prognosis but also the target of the treatment of breast cancer using humanised anti-Her2/ neu antibodies. Only cancers overexpressing the protein will respond to this therapy, but which has significant (cardiac) side effects and is expensive. It is therefore important to test for the overexpression of the protein on breast cancer cells. This paper discusses how this can be done and ongoing research into new therapeutic options targeting the involved signaling pathways.
