UNLABELLED BACKGROUND Anti-Her-2 treatment is successfully administered to Her-2 overexpressing breast cancer patients and significantly implicates upon their survival. Building on these promising results, anti-Her-2 treatment protocols were tested as an option for epithelial ovarian cancer (EOC) as well. However Her-2 signalling is known to be modulated by G-protein coupled receptors (GPCR)...

Human epidermal growth factor receptor-2 (HER-2)/neu (ErbB2), a member of the epidermal growth factor family of receptors, is overexpressed in 20-30% of breast cancers. It is an attractive target for receptor-directed antitumor therapy using mAbs. Unlike other epidermal growth factor receptor family members, HER-2/neu does not bind a high-affinity ligand, but rather functions as the preferred d...

Background &Objectives Evaluation of estrogen receptor (ER), progesterone receptor (PR), and (human epidermal growth factor receptor-2) Her-2 on core needle biopsies (CNBs) is increasingly in use to diagnosis early breast cancer, but its concordance with surgical excision (SE) is not well documented. Methods The study included 100 formalin fixed, paraffin-embedded specimens of invasive breast...

Synthetic peptide vaccines targeting B-cell epitopes of the extracellular domain of the HER-2 oncoprotein were evaluated for their capacity to elicit HER-2-specific antibodies with antiproliferative activity. Several HER-2 B-cell epitopes were identified by computer-aided analysis of protein antigenicity, and selected B-cell epitopes were synthesized colinearly with a promiscuous T-helper epito...

HER-2/neu overexpression occurs in a proportion of invasive breast carcinomasand is an adverse prognostic indicator, although its apparent strength as a prognostic indicator varies in different studies. Paradoxically, HER-2/neu is overexpressed with particularly high frequency in ductal carcinoma in situ (DCIS). We have hypothesized and presented supporting data that HER-2/neu is actively signa...
