PURPOSE CD4(+)CD25(bright) regulatory T cells (Tregs) are increased in patients with several malignancies and correlate with disease stage and prognosis. Breast cancer patients represent a heterogeneous population with unpredictable disease progression even at advanced stages. Circulating Tregs in correlation with HER-2/neu (HER) status and treatment with chemotherapy, either alone or in combin...
Two members of the EGF receptor family, HER2 and HER3, act as key oncogenes in breast cancer cells. A MAb against HER2, trastuzumab, interferes with HER2 signaling and istherapeutically effective in humans. Here, we explored the biologic effects of an antibody against HER3 (alpha-HER3ECD) in the invasive breast cancer cell lines MCF-7ADR and MDA-MB-468. Pretreating the breast cancer cells with ...
Introduction: HER-2 is a protein receptor of growth. Approximately 25% of breast cancers have overexpress HER-2. This study was designed to determine frequency of HER-2 overexpression in patients with breast cancer. Additionally, it intended to explore its relationship with some variables such as age, histopathologic diagnosis,tumor size, axillary lymph node involvement. Methods: This analyti...
background: the her-2/neu gene is located on chromosome 17q21 and encodes a 185-kda transmembrane glycoprotein with tyrosine kinase activity reported to be released in soluble form in various malignancies. objective: to evaluate the clinical significance of soluble her-2/neu as a diagnostic marker in lung cancer. methods: serum levels of soluble her-2/neu were measured in 43 patients with lung ...
background and objective: egfr and her-2 are two members of erbb/her family of type i transmembrane growth factor receptors. cox2 is an enzyme responsible for the conversion of arachidonic acid to prostaglandins, which has a major role in angiogenesis and can modelate tumor growth. the aim of this study was to determine the level of expression of egfr, her-2 and cox2 in colorectd cancer. mater...
