TI - 2-Buten-4-olide, an endogenous feeding suppressant, improves spatial performance through brain acidic fibroblast growth factor in mice.
PG - 531-6 AB - Endogenous sugar acid 2-buten-4-olide, a satiety substance, has been shown to increase the blood glucose, norepinephrine, and glucocorticoid concentrations that are known to modulate learning and memory processes. The glucose-induced release of acidic fibroblast growth factor facilitated the hippocampus-dependent memory function. In the present study, we investigated the effect of 2-buten-4-olide on the spatial performance of male DDY mice undergoing the water maze task. The intraperitoneal injection of 2-buten-4-olide (5 mg/kg) facilitated the spatial performance, which was indicated by a reduction in the escape latency in which the mouse finds and climbs the goal platform in comparison to the vehicle-injected control mice. In the probe test after removing the platform, the 2-buten-4-olide-treated mice stayed a longer time in the quadrant where the platform was originally located and crossed more frequently at the platform location than did the control mice. The pretreatment of acidic fibroblast growth factor antibody injected into the lateral ventricle eliminated the effect of 2-buten-4-olide both during the training sessions and during the probe test. Therefore, 2-buten-4-olide was found to improve the spatial performance, and this effect is mediated, at least in part, by acidic fibroblast growth factor.
