... of the adenylate cyclase inhibitor SQ22536, the PKA inhibitor H89 or the CREB inhibitor KG-501 immediately after training also blocked the formation of long-term memory, but had no effect on short-term memory formation. Thus, our pharmacological behavioural analyses showed that new protein synthesis was necessary...

... are, and how they come about. Regarding odour–food associative learning, the emerging working hypothesis is that when a mushroom body neuron is activated as a part of an odour-specific set of mushroom body neurons, and coincidently receives a reinforcement signal carried by aminergic neurons, the AC-cAMP-PKA...

..., calreticulin, annexin,type II regulatory subunit of protein kinase A (PKA) and rab GDP dissociation inhibitor and increases the cytosolic presence of adducin, actin,Ca 2+ -binding protein regucalcin/SMP30 and actin-depolymerizing factor. Supporting the putative role of PKA in the AK-III-induced activation...

... the hypertonicity-induced increase in intracellular Ca 2+ ([Ca 2+ ]i), significantly diminished hypertonic elevation of pHi, indicating that Ca 2+ signalling might be involved in NHE activation. A reduction in alkalinization and proton secretion was also observed in the presence of the protein kinase A(PKA...

... of the protein kinase C(PKC) activator phorbol-12-myristate 1-acetate (PMA) and was inhibited by the PKC inhibitor bisindolylmaleimide (BIM-1). The potentiation was not inhibited by H89, a protein kinase A (PKA) inhibitor. Proctolin did not change the intracellular concentration of 3′,5′-cyclic adenosine...
