Abstract

OBJECTIVE: Fibroblast growth factor (FGF)-21 is highly expressed in the liver and regulates hepatic glucose production and lipid metabolism in rodents. However, its role in the pathogenesis of type 2 diabetes in humans remains to be defined. The aim of this study was to quantitate circulating plasma FGF-21 levels and examine their relationship with insulin sensitivity in subjects with varying degrees of obesity and glucose tolerance. RESEARCH DESIGN AND METHODS: Forty-one subjects (8 lean with normal glucose tolerance [NGT], 9 obese with NGT, 12 with impaired fasting glucose [IFG]/impaired glucose tolerance [IGT], and 12 type 2 diabetic subjects) received an oral glucose tolerance test (OGTT) and a hyperinsulinemic-euglycemic clamp (80 mU/m2 per min) combined with 3-[3H] glucose infusion. RESULTS: Subjects with type 2 diabetes, subjects with IGT, and obese subjects with NGT were insulin resistant compared with lean subjects with NGT. Plasma FGF-21 levels progressively increased from 3.9 ± 0.3 ng/ml in lean subjects with NGT to 4.9 ± 0.2 in obese subjects with NGT to 5.2 ± 0.2 in subjects with IGT and to 5.3 ± 0.2 in type 2 diabetic subjects. FGF-21 levels correlated inversely with whole-body (primarily reflects muscle) insulin sensitivity (r = −0.421, P = 0.007) and directly with the hepatic insulin resistance index (r = 0.344, P = 0.034). FGF-21 levels also correlated with measures of glycemia (fasting plasma glucose [r = 0.312, P = 0.05], 2-h plasma glucose [r = 0.414, P = 0.01], and A1C [r = 0.325, P = 0.04]). CONCLUSIONS: Plasma FGF-21 levels are increased in insulin-resistant states and correlate with hepatic and whole-body (muscle) insulin resistance. FGF-21 may play a role in pathogenesis of hepatic and whole-body insulin resistance in type 2 diabetes.

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

  • Circulating levels of FGF21 are significantly elevated in humans during type 2 diabetes, obesity, hepatosteatosis, pancreatitis, and mitochondrial dysfunction.

    “Circulating levels of FGF21 are significantly elevated in humans during pathophysiological states, including type 2 diabetes (16, 18), obesity (22, 30, 93), hepatosteatosis (30, 79, 146), pancreatitis (117, 137), and mitochondrial dysfunction (78).”
  • FGF21 is increased in settings of obesity.

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.
