Adenylyl cyclase is a membrane-bound enzyme that catalyzes the conversion of ATP to cAMP. The inhibition of adenylyl cyclase was carried out by measuring the ability of the macrophage chemotactic protein-1 to inhibit the forskolin-induced enzyme activity. Measurement of adenylyl cyclase activity was performed according to the procedure described by Wiegn. Adenylyl cyclase activity in the pres...
متن کاملEndogenous regulator of g protein signaling proteins reduce {mu}-opioid receptor desensitization and down-regulation and adenylyl cyclase tolerance in C6 cells.
Chronic exposure of cells to mu-opioid agonists leads to tolerance which can be measured by a reduced ability to activate signaling pathways in the cell. Cell signaling through inhibitory G proteins is negatively regulated by RGS (regulator of G protein signaling) proteins. Here we examine the hypothesis that the GTPase accelerating activity of RGS proteins, by altering the lifetime of Galpha a...
متن کاملChronic opioid treatment induces adenylyl cyclase V superactivation. Involvement of Gbetagamma.
It has been known for some time that chronic treatment of neuronal cells and tissues with opioids, contrary to their acute effect, leads to an increase in cAMP accumulation. This phenomenon, defined as adenylyl cyclase superactivation, has been implicated in opiate addiction, yet the mechanism by which it is induced remains unclear. Here, we show that this phenomenon can be reproduced and studi...
متن کاملAcute and chronic activation of the mu-opioid receptor with the endogenous ligand endomorphin differentially regulates adenylyl cyclase isozymes.
While acute activation of G(i/o)-coupled receptors leads to inhibition of adenylyl cyclase, chronic activation of such receptors produces an increase in cyclic AMP accumulation, particularly evident upon withdrawal of the inhibitory agonist. This phenomenon has been referred to as adenylyl cyclase superactivation and is believed to play an important role in opiate addiction. Nine adenylyl cycla...
متن کاملRegulation of adenylyl cyclase isozymes on acute and chronic activation of inhibitory receptors.
Adenylyl cyclase superactivation, a phenomenon by which chronic activation of inhibitory Gi/o-coupled receptors leads to an increase in cAMP accumulation, is believed to play an important role as a compensatory response of the cAMP signaling system in the cell. However, to date, the mechanism by which adenylyl cyclase activity is regulated by chronic exposure to inhibitory agonists and the natu...
