This is the first report to show that epidermal growth factor (EGF) and 12-O-tetradecanoylphorbol 13-acetate (TPA) stimulate the production of PGE2 and 6-keto PGF1 alpha, an end metabolite of PGI2, in the thyroid gland. In cultured porcine thyroid cells, EGF and TPA stimulate PGE2 and 6-keto PGF1 alpha production; the maximum PG levels were obtained after 3-4 h incubation with EGF or TPA; the addition of as little as 10(-11) M EGF or 5 X 10(-11) M TPA resulted in increases in PGE2 and 6-keto PGF1 alpha, and the maximum levels were obtained with 10(-8)-10(-7) M EGF or TPA. This report also shows that EGF and TPA stimulate [3H] thymidine incorporation.
