Abstract

The gene product of the ob locus is important in the regulation of body weight. The ob product was shown to be present as a 16-kilodalton protein in mouse and human plasma but was undetectable in plasma from C57BL/6J ob / ob mice. Plasma levels of this protein were increased in diabetic ( db ) mice, a mutant thought to be resistant to the effects of ob . Daily intraperitoneal injections of either mouse or human recombinant OB protein reduced the body weight of ob / ob mice by 30 percent after 2 weeks of treatment with no apparent toxicity but had no effect on db / db mice. The protein reduced food intake and increased energy expenditure in ob / ob mice. Injections of wild-type mice twice daily with the mouse protein resulted in a sustained 12 percent weight loss, decreased food intake, and a reduction of body fat from 12.2 to 0.7 percent. These data suggest that the OB protein serves an endocrine function to regulate body fat stores.

  • Among the most often used genetic models of MASLD are mice deficient for leptin (ob/ob) or the leptin receptor (db/db).

    “Among the most often used genetic models of MASLD are mice genetically deficient for leptin (ob/ob) or the leptin receptor (db/db) (216-219).”
  • The gene is disrupted in the 2 available alleles of ob; in the original C57/Bl6J ob/ob mutation, a nonsense mutation disrupts protein function, whereas in the second coisogenic ob 2j mutation, a retroviral insertion abrogrates expression of the coding sequence altogether.

  • The failure of recombinant leptin to alter food intake or weight in db mice established the specificity of the effect and essentially excluded the possibility that the protein reduced weight as a result of an aversive effect.

  • Leptin circulates in the plasma of all mammals tested, including humans and rodents, as an '16-kD protein with a single disulfide bond that is required for bioactivity.

  • Infusions of low-dose leptin centrally replicate all the effects of peripheral leptin even at intracerebroventricular doses that do not alter plasma leptin concentrations.

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.
