Measurement of ATP production by islets depolarized with 70 mM KCl: islet ATP content and its accumulation in the extracellular medium in response to addition of the indicated citric acid cycle intermediate, its corresponding cofactors for the pyruvate/malate or isocitrate/malate cycles, and 2 mM GABA. Effect of the GABAT inhibitor 1 mM gabaculine.

The experimental conditions were the same as described above in the legend of Table 1. (More information is found in Materials and Methods section).实验条件与上文表1图例中所述一致。（详细信息可参见材料与方法（Materials and Methods）章节。）
