title: Effect of 12-O-tetradecanoylphorbol-13-acetate on polyamine metabolism in mice sensitive and resistant to lung-adenoma.
abstract: Ornithine decarboxylase activity and polyamine concentrations were determined in the lungs of mice from 0 to 20 h after treatment with 12-O-tetradecanoylphorbol-13-acetate (17.7 nmol in 0.2 ml acetone/mouse). In CFLP mice, which responded to carcinogen with development of lung-adenomas, a single topical application of TPA to hairless mouse skin increased ornithine decarboxylase activity in the lung. In contrast, in C3H/He-mg mouse strain, which were resistant to lung-adenoma production, TPA application did not increase ODC activity of the lungs.
