1 Similar inhibition of cell respiration by VIP was observed when pyruvate, fructose, and dihydroxyacetone were used as substrates, while the oxidation of glutamine, ketone bodies, and octanoate was unaffected, suggesting that the peptide acts on pyruvate metabolism.

3 The suppression of VIP effects by dichloroacetate (5 mM) and pyruvate (10 mM) and the significant decrease (18%) of the activity of the pyruvate dehydrogenase complex after incubation of the cells with the neuropeptide, support the hypothesis that the effects of VIP on glucose oxidation may occur through an inhibition of the pyruvate dehydrogenase complex.
