| Abstract: | 3-Phenylpyruvate evoked a monophasic insulin release from perifused mouse islets. L-Phenylalanine was not an insulin secretagogue and was oxidized by islets at a very low rate, suggesting that 3-phenylpyruvate does not trigger insulin release by enhancing production of reducing equivalents. Moreover, allosteric activation of glutamate dehydrogenase does not play a role in 3-phenylpyruvate-induced insulin secretion. |
