Enhanced induction of epidermal ornithine decarboxylase activity in C57BL/6 compared to DBA/2 mice by protein kinase C-activating skin tumor promoters: relevance to genetically mediated differences in promotion susceptibility

Previous work from our laboratory demonstrated that 12-O-tetradecanoylphorbol-13-acetate (TPA) or a synthetic diacylglycerol induced significantly higher epi...
