Effects of the obese Gene Product on Body Weight Regulation in ob / ob Mice

Abstract

C57BL/6J mice with a mutation in the obese ( ob )gene are obese, diabetic, and exhibit reduced activity, metabolism, and body temperature. Daily intraperitoneal injection of these mice with recombinant OB protein lowered their body weight, percent body fat, food intake, and serum concentrations of glucose and insulin. In addition, metabolic rate, body temperature, and activity levels were increased by this treatment. None of these parameters was altered beyond the level observed in lean controls, suggesting that the OB protein normalized the metabolic status of the ob / ob mice. Lean animals injected with OB protein maintained a smaller weight loss throughout the 28-day study and showed no changes in any of the metabolic parameters. These data suggest that the OB protein regulates body weight and fat deposition through effects on metabolism and appetite.

  • Leptin is an adipocyte-derived hormone whose absence in mice and humans causes abnormal energy homeostasis and profound obesity that is ameliorated by leptin treatment.

    “Leptin is an adipocyte-derived hormone whose absence in mice (1) and humans (2-4) causes abnormal energy homeostasis and profound obesity that is ameliorated by leptin treatment (5, 6).”
  • 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).”
  • Leptin-deficient Lepob/ob mice exhibit profound diabetes that can be fully prevented by low doses of leptin that do not affect body weight and food intake.

    “For example, leptin-deficient Lepob/ob mice exhibit profound diabetes that can be fully prevented by low doses of leptin that do not affect body weight and food intake (Pelleymounter et al., 1995).”

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.
