Abstract
Paraffin-embedded tissue slides from 88 infiltrating ductal breast carcinoma were examined by immunohistochemistry technique with the use of monoclonal antibody against human p65 antigen and polyclonal antibody against p65-like protein present in fetal bovine serum. Immunohistochemical analysis of expression of growth factor receptors (EGFR), protein product of oncogene c-erb B2 as well as protein product of mutated anti-oncogene p53 was also done. It was established that there is no correlation between p65 and c-erbB2, EGFR or p53 expression. In low differentiated tumors (grade III) high p53 index and high EGFR and c-erbB2 expression was connected with low p65 expression. The lack of c-erbB2 and EGFR and low p53 expression was combined usually with high p65 oncoprotein levels.
