Abstract

Leptin is a protein product of the obese (ob) gene, which is secreted by adipocytes and functions as a satiety factor to regulate food intake. The expression of the leptin receptor in several hypothalamic nuclei suggests that multiple neuronal subtypes are targets for leptin's action. Products of the proopiomelanocortin (POMC) gene are known to affect feeding behavior, and POMC neurons share a similar distribution with leptin receptor mRNA in the arcuate nucleus. We used double label in situ hybridization and computerized image analysis to test the hypothesis that POMC neurons coexpress the leptin receptor. Quantitative analysis confirmed that POMC neurons in the hypothalamus express leptin receptor mRNA. Based on this observation, we infer that POMC neurons and the products of the POMC gene may be part of the signaling pathway mediating leptin's action on feeding and perhaps other physiological functions.

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.
