1 Using either an artificial SMAD3/4-dependent reporter construct or the natural TGF-beta target, plasminogen activator inhibitor-1, we show that membrane-permeable dibutyryl cAMP, and other intracellular cAMP-elevating agents such as the phosphodiesterase inhibitor isobutyl-methylxanthine, the adenylate cyclase activator forskolin, or exogenous prostaglandin E2 (PGE2), interfere with TGF-beta-induced SMAD-specific gene transactivation.
