We have investigated the expression of three oncogenes (c-erbB-2, ras, pS2) and one supressor tumor gene (p53) in first, a clinical study, second, in an experimental one using the v-Ha-ras transgenic mice. Quantification of copy number of c-erbB-2 oncogene has been obtained by gene amplification using non-radioactive amplimer labelling on 29 mammary ductal infiltrating carcinomas. There was an apparent correlation between gene copy number and tumor grade. Immunohistochemistry on the same lesions have shown c-Ha-ras and p53 expression in high grade lesions. pS2 expression was associated to low grade lesions, which confirms the good prognosis associated to this protein. Detection of oncogenes and encoded proteins may be of value for establish...
