Abstract

A primary target of the pleiotropic metabolic hormone FGF21 is adipose tissue, where it initiates a gene expression program to enhance energy expenditure, an effect presumed to be centered on augmented UCP1 expression and activity. In UCP1 null (UCP1KO) mice, we show that the effect of FGF21 to increase the metabolic rate is abolished. However, in contrast to prior expectations, we found that increased UCP1-dependent thermogenesis is only partially required to achieve the beneficial effects of FGF21 treatment. In UCP1KO mice, there appears to be an underlying reduction in food intake following FGF21 administration, facilitating weight loss equal to that observed in wild-type animals. Furthermore, we show that UCP1-dependent thermogenesis is not required for FGF21 to improve glycemic control or to reduce circulating cholesterol or free fatty acids. These data indicate that several important metabolic endpoints of FGF21 are UCP1 independent; however, the contribution of UCP1-dependent thermogenesis to other discrete aspects of FGF21 biology requires further study.

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

  • Two independent studies revealed FGF21 significantly decreases body weight in the absence of UCP1.

    “two independent studies have revealed that FGF21 significantly decreases body weight in the absence of UCP1 (refs. 102,103).”

    From Metabolic messengers: FGF21 (2021) · cites this paper as [103]

  • UCP1 is dispensable for FGF21-mediated increases in energy expenditure.

    “However, while adipose tissues are critical for these metabolic effects, UCP1 is dispensable for FGF21-mediated increases in energy expenditure (17, 85, 111, 132).”

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.
