Abstract
1-Oleoyl-2-acetyl-glycerol induced a rise in ornithine decarboxylase activity in isolated epidermal cells in a concentration-dependent manner. The time course of the induction of ornithine decarboxylase by 1-oleoyl-2-acetyl-glycerol was similar to that by 12-O-tetradecanoylphorbol-13-acetate. A23187 did not enhance the enzyme induction caused by 1-oleoyl-2-acetyl-glycerol. Palmitoyl-DL-carnitine prevented the induction of the enzyme either by 1-oleoyl-2-acetyl-glycerol or 12-O-tetradecanoyl-phorbol-13-acetate. These results suggest that the activation of protein kinase C is an initial and essential event in the process of ornithine decarboxylase induction caused by 12-O-tetradecanoyl-phorbol-13-acetate.
