Abstract

Fibroblast growth factor-19 (FGF19) and its rodent ortholog, FGF15, are hormones produced in the distal small intestine and secreted into the circulation after a meal. In addition to controlling the enterohepatic circulation of bile acids, FGF15/19 also regulates systemic lipid and glucose metabolism. In these experiments we investigated the hypothesis that, like other gut-derived postprandial hormones, FGF15/19 can act in the central nervous system to elicit its metabolic effects. We found that FGF-receptors 1 and 4 are present in rat hypothalamus, and that their expression was reduced by up to 60% in high-fat fed rats relative to lean controls. Consistent with a potential role for brain FGF15/19 signaling to regulate energy and glucose homeostasis, and with a previous report that intracerebroventricular (i.c.v.) administration of FGF19 increases energy expenditure, we report that acute i.c.v. FGF19 reduces 24-h food intake and body weight, and acutely improves glucose tolerance. Conversely, i.c.v. administration of an FGF-receptor inhibitor increases food intake and impairs glucose tolerance, suggesting a physiological role for brain FGF receptor signaling. Together, these findings identify the central nervous system as a potentially important target for the beneficial effects of FGF19 in the treatment of obesity and diabetes.

  • Fgf15 can signal through the brain to modulate glucose homeostasis and glucagon secretion.

    “Importantly, Fgf15 can also signal through the brain to modulate glucose homeostasis 45 and glucagon secretion 46.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
