To emphasize this point more specifically, we also assessed ATP effects on signal output in living cells (that is, the normal test environment for FRET-based biosensors). Changes in intracellular ...
Anticholinergics prevent the increases in intracellular concentration of Ca++ ... catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3, 5-adenosine monophosphate (cyclic AMP).
