Skin-painting studies in female CD-1 or SENCAR mice involved initiation by a single topical exposure to 7,12-dimethylbenz[a]-anthracene (DMBA) applied to the dorsal skin, followed by repeated percutaneous exposure to a tumor promoter, either DEHP or 12-O-tetradecanoylphorbol-13-acetate 12-O-tetradecanoylphorbol-13-acetate 12-O-tetradecanoylphorbol-13-acetate 12-O-tetradecanoylphorbol-13-acetate 12-O-tetradecanoylphorbol-13-acetate
