Abstract

Basic fibroblast growth factor (FGF-2) has been isolated from the brain, but the regulation of FGF-2 synthesis in the brain is not yet fully understood. Since exogenously administered FGF-2 has been reported to suppress food intake as well as the secretion of gastric acid and pepsin in rats, we examined the effect of fasting on FGF-2 mRNA levels in the hypothalamus and the cerebral cortex of male rats, using RNase protection assay. Fasting for 72 h resulted in an approximately 2-fold increase in FGF-2 mRNA level in the hypothalamus but did not affect FGF-2 mRNA level in the cerebral cortex significantly. These findings support the hypothesis that FGF-2 plays a significant role in regulation of hypothalamic function.
