Abstract

Fibroblast growth factor 21 (FGF21) is a hepatokine that acts as a global starvation signal to modulate fuel partitioning and metabolism and repress growth; however, the site of action of these diverse effects remains unclear. FGF21 signals through a heteromeric cell-surface receptor composed of one of three FGF receptors (FGFR1c, FGFR2c or FGFR3c) in complex with β-Klotho, a single-pass transmembrane protein that is enriched in metabolic tissues. Here we show that in addition to its known effects on peripheral metabolism, FGF21 increases systemic glucocorticoid levels, suppresses physical activity and alters circadian behavior, which are all features of the adaptive starvation response. These effects are mediated through β-Klotho expression in the suprachiasmatic nucleus of the hypothalamus and the dorsal vagal complex of the hindbrain. Mice lacking the gene encoding β-Klotho (Klb) in these regions are refractory to these effects, as well as those on metabolism, insulin and growth. These findings demonstrate a crucial role for the nervous system in mediating the diverse physiologic and pharmacologic actions of FGF21.

  • KLB expression is primarily restricted to specific metabolic tissues (liver, pancreas, adipose) and lower in brain; KLB is not expressed in muscle.

    “KLB expression is primarily restricted to specific metabolic tissues (for example, the liver, pancreas and adipose tissue)5, and lower expression is observed in the brain22,48–50. Despite some reports to the contrary51,52, KLB is not expressed in muscle5,41.”

  • KLB is expressed in numerous cell types and regions throughout the hypothalamus and CNS, in contrast to reported restriction to the suprachiasmatic nucleus.

    “In contrast to the reported restriction of KLB expression to the suprachiasmatic nucleus49, KLB is expressed in numerous cell types and regions throughout the hypothalamus48 (and CNS).”

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.
