Abstract

Mutations in the mouse diabetes (db) gene result in obesity and diabetes in a syndrome resembling morbid human obesity. Previous data suggest that the db gene encodes the receptor for the obese (ob) gene product, leptin. A leptin receptor was recently cloned from choroid plexus and shown to map to the same 6-cM interval on mouse chromosome 4 as db. This receptor maps to the same 300-kilobase interval as db, and has at least six alternatively spliced forms. One of these splice variants is expressed at a high level in the hypothalamus, and is abnormally spliced in C57BL/Ks db/db mice. The mutant protein is missing the cytoplasmic region, and is likely to be defective in signal transduction. This suggests that the weight-reducing effects of leptin may be mediated by signal transduction through a leptin receptor in the hypothalamus.

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 receptor RNA was alternatively spliced and only one of the splice variants, referred to as ObRb at the time (also known as LepR-l), was mutant in C57Bl/Ks db/db mice.

    “It was subsequently shown that leptin receptor RNA was alternatively spliced and that only one of the splice variants, referred to as ObRb at the time (also known as LepR-l), was mutant in C57Bl/Ks db/db mice (25,26).”

  • ObRb was highly enriched in the hypothalamus in precisely those nuclei that alter body weight when lesioned.

  • Mice lacking only LepRb exhibit a phenotype similar to leptin-deficient ob/ob mice.

    “mice that lack only LepRb (e.g. db/db mice) exhibit a phenotype similar to leptin-deficient ob/ob mice (100).”

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.
