Abstract

BACKGROUND & AIMS: Fibroblast growth factor 21 (FGF-21) is a liver-derived metabolic regulator induced by energy deprivation. However, its regulation in humans is incompletely understood. We addressed the origin and regulation of FGF-21 secretion in humans. METHODS: By determination of arterial-to-venous differences over the liver and the leg during exercise, we evaluated the organ-specific secretion of FGF-21 in humans. By four different infusion models manipulating circulating glucagon and insulin, we addressed the interaction of these hormones on FGF-21 secretion in humans. RESULTS: We demonstrate that the splanchnic circulation secretes FGF-21 at rest and that it is rapidly enhanced during exercise. In contrast, the leg does not contribute to the systemic levels of FGF-21. To unravel the mechanisms underlying the regulation of exercise-induced hepatic release of FGF-21, we manipulated circulating glucagon and insulin. These studies demonstrated that in humans glucagon stimulates splanchnic FGF-21 secretion whereas insulin has an inhibitory effect. CONCLUSIONS: Collectively, our data reveal that 1) in humans, the splanchnic bed contributes to the systemic FGF-21 levels during rest and exercise; 2) under normo-physiological conditions FGF-21 is not released from the leg; 3) a dynamic interaction of glucagon-to-insulin ratio regulates FGF-21 secretion in humans.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Circulating FGF21 levels are derived primarily, if not exclusively, from the liver under physiological conditions in both rodents and humans.

    “circulating levels of FGF21 are now known to be derived primarily, if not exclusively, from the liver under physiological conditions in both rodents6 and humans7.”

    From Metabolic messengers: FGF21 (2021) · cites this paper as [7]

  • Under most physiological conditions, circulating levels of FGF21 are derived primarily from the liver.

    “Notably, despite the expression of Fgf21 mRNA in these tissues, under most physiological conditions, circulating levels of FGF21 are derived primarily from the liver (46, 86).”
  • In humans, in response to exercise, FGF21 is produced from the liver, not muscle.

    “In addition, in humans in response to exercise, FGF21 is produced from the liver not muscle (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.
