1 Dibutyryl cAMP increased phosphorylation of Akt and CREB, both of which were reversed by H89, wortmannin and the Akt inhibitor SH-6. Cyclic AMP cAMP responsive element binding protein 1 Mus musculus
2 In dominant-negative CREB-transfected cells, dibutyryl cAMP no longer prevented cell injury or inhibited changes in mRNA expression of Bcl-2 and Bax. Cyclic AMP cAMP responsive element binding protein 1 Mus musculus
3 These findings suggest that elevation of endogenous cAMP effectively prevents radiocontrast nephropathy through activation of A kinase/PI 3-kinase/Akt followed by CREB phosphorylation and enhanced expression of Bcl-2. Cyclic AMP cAMP responsive element binding protein 1 Mus musculus
