Abstract

Diabetes mellitus is a major health concern, affecting more than 5% of the population. Here we describe a potential novel therapeutic agent for this disease, FGF-21, which was discovered to be a potent regulator of glucose uptake in mouse 3T3-L1 and primary human adipocytes. FGF-21-transgenic mice were viable and resistant to diet-induced obesity. Therapeutic administration of FGF-21 reduced plasma glucose and triglycerides to near normal levels in both ob/ob and db/db mice. These effects persisted for at least 24 hours following the cessation of FGF-21 administration. Importantly, FGF-21 did not induce mitogenicity, hypoglycemia, or weight gain at any dose tested in diabetic or healthy animals or when overexpressed in transgenic mice. Thus, we conclude that FGF-21, which we have identified as a novel metabolic factor, exhibits the therapeutic characteristics necessary for an effective treatment of diabetes.

  • FGF21 stimulates uptake of glucose by adipocytes and inhibits production of glucose in the liver.

    “In general, FGF21 stimulates the uptake of glucose by adipocytes and inhibits the production of glucose in the liver.”

    From Physical Exercise-Induced Myokines and Muscle-Adipose Tissue Crosstalk: A Review of Current Knowledge and the Implications for Health and Metabolic Diseases (2018) · cites this paper as Kharitonenkov et al., 2005

    The Identification of FGF-21 in vitro bioactivity section reports that FGF-21 stimulated glucose uptake in mouse and human adipocytes. The Discussion proposes reduced glucagon secretion as a possible contributor to lower blood glucose, but does not establish that FGF-21 inhibits glucose production in the liver; that part of the claim is overstated. Page numbers are unavailable in our copy. (LLM, conf=0.88)

  • FGF21 acts in the control of glucose and lipid homeostasis.

    “FGF21 acts in the control of glucose and lipid homeostasis (Kharitonenkov et al., 2005).”
  • FGF21 appears to protect pancreatic β cells from cell death induced by glycotoxicity.

    “In addition, FGF21 appears to protect pancreatic β cells from cell death induced by glycotoxicity (Kharitonenkov et al., 2005, 2007).”

    From Physical Exercise-Induced Myokines and Muscle-Adipose Tissue Crosstalk: A Review of Current Knowledge and the Implications for Health and Metabolic Diseases (2018) · cites this paper as Kharitonenkov et al., 2005

    The pancreatic-islet methods describe measurements of insulin and glucagon release, not β-cell survival. The Discussion reports no effect on insulin secretion; searches for glycotoxicity, β-cell death, and protection found no passage addressing whether FGF-21 prevents glycotoxicity-induced cell death. (LLM, conf=0.72)

    Experimental — accuracy not yet measured
  • Mice that overexpress FGF-21, a circulating FGF which is induced by a ketogenic diet, are lean and have increased brown fat, suggesting that the beneficial metabolic effects induced by a ketogenic diet are brought about in part by increases in BAT mass.

    “Interestingly, mice that overexpress FGF-21, a circulating FGF which is induced by a ketogenic diet 106, are lean and have increased brown fat 107, suggesting that the beneficial metabolic effects induced by a ketogenic diet are brought about in part by increases in BAT mass.”

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.
