HER-2 Signaling in Human Breast Cancer
1.1 erbB family HER-2 is a member of the erbB family of receptor tyrosine kinases. Epidermal Growth Factor Receptor (EGFR) was first identified as the cellular homolog of the transduced oncogene of the avian retroviruses such as avian ERythroBlastosis virus, which causes erythroleukemia and fibrosarcoma and gives rise to the family name (erbB). EGFR, as its name implies, was shown by Stanley Co...
متن کاملHER-2 gene amplification in human breast cancer without concurrent HER-2 over-expression
BACKGROUND Testing for human epidermal growth factor receptor-2 (HER-2) in breast cancer is performed by either immunohistochemistry (IHC) or in situ hybridization (ISH). The growth factor receptor-bound protein-7 (GRB7) gene is in close proximity to HER-2 on chromosome 17q11-12 and codes a signal transduction molecule shown to be an independent adverse marker in breast cancer. METHODS HER-2 ...
متن کاملComparative impact of trastuzumab and cyclophosphamide on HER-2-positive human breast cancer xenografts.
PURPOSE Metronomic chemotherapy is a minimally toxic and frequently effective new treatment strategy that is beginning to show promising phase II clinical trial results, particularly for metastatic breast cancer when combined with various molecularly targeted antitumor agents. Here, we assessed a treatment strategy that uses trastuzumab plus daily oral metronomic cyclophosphamide on metastatic ...
متن کاملHER-2/neu diagnostics in breast cancer
HER-2/neu status of the primary breast cancer (PBC) is determined by immunohistochemistry and fluorescent in situ hybridization. Because of a variety of technical factors, however, the PBC may not accurately reflect the metastatic tumor in terms of HER-2/neu status. Recently published guidelines recommend that tumors be defined as HER-2/neu positive if 30% or more of the cells are 3+. Circulati...
متن کاملBreast Carcinoma; Human Epidermal Growth Factor Receptor-2 (HER-2) and Grading Correlation
Introduction: Overexpression of Human Epidermal Growth factor Receptor-2 (HER-2) is one of the most important prognostic and predictive factors of breast cancer, observed in 25% - 30% of breast carcinoma patients leading to poor prognosis and feasible anti HER-2 antibody drugs. The objective of this study was to evaluate the HER-2 frequency in target population and its correlat...
