Abstract

Fibroblast growth factor 21 (FGF21) is a liver-derived endocrine factor that stimulates glucose uptake in adipocytes. Here, we show that FGF21 activity depends on βKlotho, a single-pass transmembrane protein whose expression is induced during differentiation from preadipocytes to adipocytes. βKlotho physically interacts with FGF receptors 1c and 4, thereby increasing the ability of these FGF receptors to bind FGF21 and activate the MAP kinase cascade. Knockdown of βKlotho expression by siRNA in adipocytes diminishes glucose uptake induced by FGF21. Importantly, administration of FGF21 into mice induces MAP kinase phosphorylation in white adipose tissue and not in tissues without βKlotho expression. Thus, βKlotho functions as a cofactor essential for FGF21 activity.

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

  • FGF21 binding promotes formation of a dimeric FGFR1c-KLB complex, activates tyrosine kinase domains and propagates signalling through ERK phosphorylation.

  • Loss of KLB abolishes all effects of FGF21 in vitro and in vivo.

    “loss of KLB abolishes all effects of FGF21 in vitro and in vivo46,53–56.”

    From Metabolic messengers: FGF21 (2021) · cites this paper as [53]

  • Endocrine FGFs require a coreceptor to provide signaling specificity, which for FGF21 and FGF19 is β-klotho.

    “Importantly, since FGF receptors are ubiquitously expressed, endocrine FGFs require a coreceptor to provide signaling specificity, which for FGF21 and FGF19 is the coreceptor β-klotho (71, 99, 140).”
  • FGF21 functions in target tissues that express FGFR1c and the obligate coreceptor β-klotho.

    “FGF21 functions in target tissues that express the traditional FGF receptor FGFR1c and the obligate coreceptor β-klotho (2, 27, 71, 99, 124, 140).”

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.
