Abstract

The endocrine-derived hormone fibroblast growth factor (FGF) 19 has recently emerged as a potential target for treating metabolic disease. Given that skeletal muscle is a key metabolic organ, we explored the role of FGF19 in that tissue. Here we report a novel function of FGF19 in regulating skeletal muscle mass through enlargement of muscle fiber size, and in protecting muscle from atrophy. Treatment with FGF19 causes skeletal muscle hypertrophy in mice, while physiological and pharmacological doses of FGF19 substantially increase the size of human myotubes in vitro. These effects were not elicited by FGF21, a closely related endocrine FGF member. Both in vitro and in vivo, FGF19 stimulates the phosphorylation of the extracellular-signal-regulated protein kinase 1/2 (ERK1/2) and the ribosomal protein S6 kinase (S6K1), an mTOR-dependent master regulator of muscle cell growth. Moreover, mice with a skeletal-muscle-specific genetic deficiency of β-Klotho (KLB), an obligate co-receptor for FGF15/19 (refs. 2,3), were unresponsive to the hypertrophic effect of FGF19. Finally, in mice, FGF19 ameliorates skeletal muscle atrophy induced by glucocorticoid treatment or obesity, as well as sarcopenia. Taken together, these findings provide evidence that the enterokine FGF19 is a novel factor in the regulation of skeletal muscle mass, and that it has therapeutic potential for the treatment of muscle wasting.

  • Administration of FGF19 promoted muscle hypertrophy and increased grip strength without AKT activation but with ERK stimulation.

    “It has been recently reported that administration of FGF19 promoted muscle hypertrophy and increased grip strength without AKT activation but with ERK stimulation26.”
  • Injecting mice daily with exogenous FGF19 increased skeletal muscle mass and strength.

    “Injecting mice daily with exogenous FGF19, a closely related endocrine FGF member produced in the gut, increased skeletal muscle mass and strength.”
  • Skeletal muscle hypertrophy effects were not elicited by administering FGF21.

    “Remarkably, the skeletal muscle hypertrophy effects were not elicited by administrating FGF21.22”
  • 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.”

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.
