1 In previous studies we found that NGF production is up-regulated by 12-O-tetradecanoylphorbol 13-acetate (TPA) and serum, down-regulated by corticosterone, and unaffected by dibutyryl-cyclic AMP (db-cyclic AMP) in fibroblasts. Tetradecanoylphorbol Acetate nerve growth factor Homo sapiens
2 In previous studies we found that NGF production is up-regulated by 12-O-tetradecanoylphorbol 13-acetate (TPA) and serum, down-regulated by corticosterone, and unaffected by dibutyryl-cyclic AMP (db-cyclic AMP) in fibroblasts. Tetradecanoylphorbol Acetate nerve growth factor Homo sapiens
3 TPA and serum together stimulated NGF production 10-fold more than either agent alone. Tetradecanoylphorbol Acetate nerve growth factor Homo sapiens
4 Forskolin and db-cyclic AMP prevented NGF mRNA induction by TPA and serum without changing basal levels. Tetradecanoylphorbol Acetate nerve growth factor Homo sapiens
5 TPA induced c-fos and junB mRNAs transiently and preceding NGF mRNA induction but c-jun mRNA remained undetectable. Tetradecanoylphorbol Acetate nerve growth factor Homo sapiens
6 Thus, TPA induction of NGF mRNA is modulated differentially by corticosterone and cyclic AMP. Tetradecanoylphorbol Acetate nerve growth factor Homo sapiens
