Abstract

We tested whether leptin can ameliorate diabetes independent of weight loss by defining the lowest dose at which leptin treatment of ob/ob mice reduces plasma glucose and insulin concentration. We found that a leptin dose of 12.5 ng/hr significantly lowers blood glucose and that 25 ng/hr of leptin normalizes plasma glucose and insulin without significantly reducing body weight, establishing that leptin exerts its most potent effects on glucose metabolism. To find possible mediators of this effect, we profiled liver mRNA using microarrays and identified IGF Binding Protein 2 (IGFBP2) as being regulated by leptin with a similarly high potency. Overexpression of IGFBP2 by an adenovirus reversed diabetes in insulin-resistant ob/ob, Ay/a, and diet-induced obese mice, as well as insulin-deficient streptozotocin-treated mice. Hyperinsulinemic clamp studies showed a 3-fold improvement in hepatic insulin sensitivity following IGFBP2 treatment of ob/ob mice. These results show that IGFBP2 can regulate glucose metabolism, a finding with potential implications for the pathogenesis and treatment of diabetes.

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Leptin administration to leptin-deficient mice or humans ameliorates hyperglycemia and hyperinsulinemia even when differences in food intake are controlled by pair-feeding.

    “leptin administration to leptin-deficient mice or humans ameliorates hyperglycemia and hyperinsulinemia (60, 141) even when differences of food intake are controlled by pair-feeding (80, 158).”

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.
