c- erbB-2 Immunohistochemistry in Paraffin Tumors
2003Immunohistochemistry is the study of the intracellular distribution of antigens based on the formation of an immune complex. The concept is based on the application of a specific antibody to the antigen to be detected and visualization of the antigen-antibody reaction with a staining procedure.

Overexpression of erbB-2 is important in the pathogenesis of a variety of human neoplasms. Overexpression of the erbB-2 gene product has been associated with poor clinical prognosis with respect to malignancies originating in the ovary, breast, gastrointestinal tract, salivary gland, and lung (1-4) and has led to the development of several therapeutic ...

Clinical & Experimental Metastasis, 2002
Overexpression of the c-erbB-2 protein (also called HER-2/neu) is observed in a variety of malignancies including colorectal cancer (CRC). In this study we aimed to evaluate the rate of c-erbB-2 overexpression in our tumor collection and to clarify its correlation with the chromosomal status at the c-erbB-2 locus in CRC.

Seminars in oncology, 1989
The neu gene was first identified in rat tumors that had been induced by the carcinogen ethyl nitrosourea. The human homolog of neu, usually designated c-erbB-2, is located on chromosome 17, q21. It specifies a transmembrane receptor-like phosphoglycoprotein that is closely related to the EGFr (c-erbB-1). The ligand for c-erbB-2 is not known.

C-erbB-2 protein in the sera of breast cancer patients
Breast Cancer Research and Treatment, 1992The c-erbB-2 protein was measured in sera of patients with breast cancer or benign breast diseases to study the significance of this protein as a tumor marker. The mean value and positive rate for this protein (assuming 20U/ml as the cut-off value) were 11.8 U/ml (0%) in benign breast disease (n = 30), 11.8 U/ml (3.1%) in stage I/II primary breast ...

Expression of neu/c-erbB-2 in human brain tumors
Human Pathology, 1994The neu/c-erbB-2 oncogene encodes a 185 kd transmembrane protein (p185). Here we have used the monoclonal antibody (mAb) 3B5 to determine the expression of p185 in a series of fixed biopsy specimens of 180 human brain tumors, including the most frequent entities and, in addition, 18 recurrent gliomas with malignant progression.

No evidence for c-erbB-2 overexpression in cutaneous melanoma.
Anticancer research, 2001Recent studies have demonstrated the expression of the c-erbB-2 (HER-2/neu) oncoprotein in several malignant tumors and have related its overexpression with poor prognosis. Because cutaneous melanoma is a malignant tumor associated with poor prognosis, we investigated the expression of c-erbB-2 protein in cutaneous melanoma and in melanoma metastatic ...

The c-erbB-2 Protein in Primary and Metastatic Breast Carcinomas
Ultrastructural Pathology, 1991Material from 41 patients with primary breast carcinoma and lymph node metastases at the time of primary surgical intervention was immunostained for c-erbB-2 protein, neuron-specific enolase (NSE), and estrogen receptors. Thirty of the primary breast carcinomas were of ductal type. Six were classified as infiltrating lobular carcinomas, 2 were apocrine,

Expression of c‐erbB‐2 oncoprotein in human thyroid tumours
Histopathology, 1999Aimsc‐erbB‐2 expression has been found to be a potential marker of aggressive biological behaviour in some tumours, but the role played by this oncoprotein in the development and maintenance of thyroid tumours is still controversial. Therefore our objective was to determine whether c‐erbB‐2 was overexpressed in a large retrospective series of human ...

Expression of Bcl-2 and c-ErbB-2 in colorectal neoplasia
Pathology & Oncology Research, 2001Several studies have been demonstrated the value of c-ErbB-2 and Bcl-2 in predicting the biological behaviour of tumors. The aim of this study was to investigate Bcl-2 and c-ErbB-2 expression in colorectal carcinomas and the correlation between their presence and other clinicopathologic parameters.
