Báo cáo khoa học: Inhibition of the NF-jB transcriptional activity by protein kinase A

The cAMP-dependent protein kinase (PKA) signaling pathway plays a major role in a number of pathophysio-logical conditions. However, there have been conflicting evidences regarding the action of cAMP/PKA on nuclear factor-jB(NF-jB). Inthis study,wehaveexplored the effect of cAMP/PKA on NF-jBactivity and determined its molecular mechanism. PKA activating agents or expression of thecatalyticsubunitofPKA(PKAc) inhibitedtheNF-jB-dependent reporter gene expression induced by tumor nec-rosis factora(TNFa). ...
