Background. The c-erbB2 (Her2/neu) oncogene is located on the long arm of chromosome 7, encoding for a 185 kD transmembrane glycoprotein p185 with tyrosine kinase receptor function. Several studies have shown that overexpression of c-erbB2 (Her-2/neu) gene has been associated with breast cancer appearance. The aim of the present study was to investigate the relationship between amplification of c-erbB2 gene and the appearance of breast cancer in menopausal women.
Materials and methods. Paraffin embedded tumour tissue were obtained from patients with breast cancer (n=20). Blood samples from age matched healthy women (n=20) served as control. The amplification of c-erbB2 gene was determined by PCR reaction using the allele specific primers.
Results. The amplification of c-erbB2 gene was significantly higher in patients compared as control (p<0.05).
Conclusion. The results suggest that amplification of c-erbB2 gene may be linked with appearance of breast cancer in menopausal women.
