Normal thyroid tissues showed no significant immunostaining reaction to antibodies for EGF, and products of ras and myc oncogenes. The incidence of EGF positivity was 27%, 46% and 76% in Graves' disease, follicular adenoma, and carcinoma, repectively. The incidence of positivity of ras oncogene product was 27%, 38%, and 82% in Graves' disease, follicular adenoma and carcinoma, respectively. The incidence of positivity of myc oncogene product was 18%, 46% and 71% in Graves' disease, Follicular adenoma, and carcinoma, respectively. These results suggest that EGF, and ras and myc oncogenes or proto-oncogenes play a role in neoplastic lesions of the thyroid., Acta medica Nagasakiensia. 1989, 34(2-4), p.70-75}, pages = {70--75}, title = {Expression of EGF and, Ras and Myc Oncogene Products in Normal, Graves' Thyroid, Adenoma, and Carcinoma of the Thyroid}, volume = {34}, year = {1989} }
