1 In addition, we examined whether PMA affects interleukin-1beta (IL-1beta) stimulation of COX-2 and PGE(2) production. Tetradecanoylphorbol Acetate mitochondrially encoded cytochrome c oxidase II Homo sapiens
2 PMA increased COX-2 protein levels 2. Tetradecanoylphorbol Acetate mitochondrially encoded cytochrome c oxidase II Homo sapiens
3 Inhibition of either p38 kinase or protein kinase C (PKC) prevented PMA-stimulated COX-2. Tetradecanoylphorbol Acetate mitochondrially encoded cytochrome c oxidase II Homo sapiens
4 These findings indicate that: 1) PMA, acting through PKC and p38 kinase, enhances COX-2 expression, but chronic treatment with PMA partially inhibits IL-1beta stimulation of COX-2; and 2) exogenous PGF(2alpha) is involved in neonatal ventricular myocyte growth but endogenous COX-2 products are not. Tetradecanoylphorbol Acetate mitochondrially encoded cytochrome c oxidase II Homo sapiens
