TL;DR: In Torpedo synaptic vesicles, only 5% of the total acetylcholine or ATP content is free, and that the rest is adsorbed to an intravesicular proteoglycan matrix that regulates the availability of free diffusible ACh and ATP.

Endogenous hemichannels play a role in the release of ATP from Xenopus oocytes
Laia Bahima,Jordi Aleu,Marc Elias,Mireia Martín-Satué,Ashraf Muhaisen,Joan Blasi,Jordi Marsal,Carles Solsona +7 more
TL;DR: The release of ATP is found to be coincident with the opening of hemichannels from Xenopus oocytes that are formed by Connexin 38 (Cx38), an endogenous, specific type of connexin, and the activation of these endogenous connexons allows transfer of Lucifer Yellow.

Release of ATP induced by hypertonic solutions in Xenopus oocytes
Jordi Aleu,Mireia Martín-Satué,Piedad Navarro,Ivanna Pérez de Lara,Laia Bahima,Jordi Marsal,Carles Solsona +6 more
TL;DR: Since the ATP measured is the balance between ATP release and ATP degradation by ecto‐enzymes, the nucleoside triphosphate diphosphohydrolase (NTPDase) activity of the oocyte surface during osmotic stress is measured, as the calcium‐dependent hydrolysis of ATP, which was inhibited by more than 50 % in hypertonic conditions.

Gadolinium inhibition of ecto-nucleoside triphosphate diphosphohydrolase activity in Torpedo electric organ
TL;DR: It is shown that gadolinium, an established blocker of stretch-activated channels, efficiently inhibits E-NTPDase activity of Torpedo electric organ as well as apyrase from potato tuber, frequently used in inhibition experiments.

Calcium-dependent acetylcholine release from Xenopus oocytes: simultaneous ionic currents and acetylcholine release recordings.
TL;DR: It is shown that SNARE proteins are present in native Xenopus oocytes and that those oocytes injected with acetylcholine and presynaptic plasma membranes extracted from the electric organ of Torpedo marmorata assume some of the functions of a cholinergic nerve terminal.
