Abstract

"Browning," the appearance and activation of brown-in-white (brite) adipose cells within inguinal white adipose tissue (iWAT), and induction of uncoupling protein 1 (UCP1) correlate with fibroblast growth factor-21 (FGF21)-induced weight loss and glucose homeostasis improvements. Therefore, antiobesity therapies targeting browning and brite adipocyte activation are currently being sought. To test the dependence of weight loss on browning, we examined whether this event was responsible for FGF21-Fc's beneficial effects. Lean and diet-induced obese mice housed at 21°C or 30°C that received FGF21-Fc exhibited similar degrees of body weight reduction and glucose homeostasis improvement. Substantial browning of iWAT occurred only in FGF21-Fc-treated lean mice housed at 21°C. Further, FGF21-Fc-treated Ucp1(-/-) mice showed robust improvements in body weight, glucose homeostasis, and plasma lipids, associated with increased energy expenditure and FGF21-Fc-induced Ppargc1 expression in iWAT. We conclude that FGF21 requires neither UCP1 nor brite adipocytes to elicit weight loss and improve glucose homeostasis.

  • 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 [102]

  • Véniant et al demonstrated that beneficial effects of weight loss observed after cold were not directly related to FGF21-induced browning.

    “Despite the evidence of FGF21 production in WAT, controversial results were published by Véniant et al 94 who demonstrated that beneficial effects of weight loss observed after cold were not directly related to FGF21‐induced browning.”

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.
