8 8-bromo-cAMP stimulated NOx production and increased steady-state levels of iNOS mRNA in rat VSMC in a time- and dose-dependent manner. 8-Bromo Cyclic Adenosine Monophosphate nitric oxide synthase 2 Rattus norvegicus

12 Actinomycin D abolished the cAMP-induced iNOS mRNA, whereas cycloheximide remarkably increased iNOS mRNA levels in the presence and absence of 8-bromo-cAMP (superinduction). Cyclic AMP nitric oxide synthase 2 Rattus norvegicus
13 Actinomycin D abolished the cAMP-induced iNOS mRNA, whereas cycloheximide remarkably increased iNOS mRNA levels in the presence and absence of 8-bromo-cAMP (superinduction). Cycloheximide nitric oxide synthase 2 Rattus norvegicus
14 Actinomycin D, but not dexamethasone, completely abolished the cycloheximide-induced iNOS mRNA. Dactinomycin nitric oxide synthase 2 Rattus norvegicus
15 Actinomycin D, but not dexamethasone, completely abolished the cycloheximide-induced iNOS mRNA. Cycloheximide nitric oxide synthase 2 Rattus norvegicus
16 The half-life of cAMP-induced iNOS mRNA was approximately 2 h, whereas no decay in the cycloheximide-induced iNOS mRNA was observed during 12 h. These results demonstrate that iNOS gene is upregulated by cAMP and the superinduction of iNOS mRNA is attributable to increased mRNA stability in rat VSMC.
