The effect of topical application of PGE on induction of ODC in mouse epidermis was measured. When direct induction of ODC by TPA was blocked by also applying indomethacin, maximum ODC activity occurred only when PGE was applied simultaneously with TPA 4% hr before killing of the mice. If either TPA

Abstract
Nerve growth factor (NGF), epidermal growth factor (EGF), adenosine 3β²,5β²βcyclic monophosphate (cAMP), and cholera toxin all increase the specific activity of ornithine decarboxylase (ODC) in the PC12 nerveβlike cell line. A phosphodiesterase inhibitor augments the effect of NGF on the induction of ODC in these cells, while it is only additive with the EGF response. These data suggest that cAMP has an intermediary role in the induction of ODC by NGF and that cAMP is not involved in the EGF response.
