Abstract: | Prostaglandin (PG) E(2) release is induced in pulmonary A549 cells by the NF-{kappa}B-activating stimuli interleukin-1{beta} (IL-1{beta}) and phorbol 12-myristate 13-acetate (PMA). Adenoviral over-expression of I{kappa}B{alpha}ΔN, a dominant NF-{kappa}B inhibitor, prevents NF-{kappa}B-dependent transcription and was used to qualify the role of NF-{kappa}B in the release of PGE2. I{kappa}B{alpha}ΔN repressed IL-1{beta}-induced, but not PMA-induced, cycloxygenase-2 (COX-2) and microsomal prostaglandin E synthase (mPGES) expression. These data conclusively demonstrate a substantial role for NF-{kappa}B in the co-ordinate induction of COX-2, mPGES and in the corresponding release of PGE2 by IL-1{beta}. However, other pathways are primarily responsible for PGE2 release induced by PMA. |
