PURPOSE Experimental data suggest a complex cross-talk between HER-2 and estrogen receptor, and it has been hypothesized that HER-2-positive tumors may be less responsive to certain endocrine treatments. Clinical data, however, have been conflicting. We have conducted a meta-analysis on the interaction between the response to endocrine treatment and the overexpression of HER-2 in metastatic bre...
AIM OF THE STUDY To determine whether the expression of HER-3 influences the survival of HER-2 positive patients with breast cancer (BC). MATERIAL AND METHODS In the present work, the expression of HER-3 in a group of 35 HER-2 positive patients with BC was studied by performing immunohistochemistry (IHC) in formalin-fixed paraffin embedded tissues. RESULTS Higher HER-3 status if estimated b...
It is appropriate that this lecture is being given in Cambridge because Marjory Stephenson spent most of her life here and indeed was born only ten miles away in Bunvell. However, she taught for a while in London at Unix ersity College and King’s College of Household Science. Her connection with the latter College is of particular interest to me because King’s College of Household Science event...
The present study explores the correlation of human epidermal growth factor receptor-2 (HER-2) protein expression with sentinel lymph node (SLN) metastasis and prognosis of breast cancer. The breast cancer tissues and adjacent tissues were obtained from patients with primary breast cancer. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect the mRNA level of HER-2...
BACKGROUND Serum HER-2/neu antigen concentrations have been reported to correlate with increased tumor volume in patients with breast cancer. We measured serum CA 15-3, a surrogate marker of disease burden, and correlated serum CA 15-3 with serum HER-2/neu and analyzed the association of both markers with clinical outcomes. METHODS Pretreatment serum samples from 566 patients were retrospecti...
Her-2 transgenic (Tg) mice were generated with wild-type human c-ErbB-2 (Her-2) under the whey acidic protein promoter. They are tolerant to Her-2 and appropriate for testing Her-2 vaccines. The expression of transmembrane ErbB-2 from the whey acidic protein-Her-2 cassette and its up-regulation by insulin and hydrocortisone was verified by in vitro transfection. The transgene cassette was micro...
There is controversy over the role of Her-2 in osteosarcoma, with some investigators reporting association between expression and adverse outcome, whereas others point to the lack of gene amplification and membranous expression by immunohistochemistry (IHC) as inconsistent with biological significance. Her-2 normally requires pairing with epidermal growth factor receptor (EGFR), Her-3, or Her-4...
BACKGROUND & OBJECTIVE In breast cancer, the HER-2/neu gene is amplified in 20-30 per cent of cases. The mechanism by which the amplification/overexpression occurs is not known. Elevated serum HER-2/neu levels have been shown to be associated with a poor clinical prognosis and decreased survival in early stage breast cancer patients, and thus might help in management of the disease. The present...
