Abstract

Estrogens regulate body weight and reproduction primarily through actions on estrogen receptor-α (ERα). However, ERα-expressing cells mediating these effects are not identified. We demonstrate that brain-specific deletion of ERα in female mice causes abdominal obesity stemming from both hyperphagia and hypometabolism. Hypometabolism and abdominal obesity, but not hyperphagia, are recapitulated in female mice lacking ERα in hypothalamic steroidogenic factor-1 (SF1) neurons. In contrast, deletion of ERα in hypothalamic pro-opiomelanocortin (POMC) neurons leads to hyperphagia, without directly influencing energy expenditure or fat distribution. Further, simultaneous deletion of ERα from both SF1 and POMC neurons causes hypometabolism, hyperphagia, and increased visceral adiposity. Additionally, female mice lacking ERα in SF1 neurons develop anovulation and infertility, while POMC-specific deletion of ERα inhibits negative feedback regulation of estrogens and impairs fertility in females. These results indicate that estrogens act on distinct hypothalamic ERα neurons to regulate different aspects of energy homeostasis and reproduction.

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

  • Estrogens directly act on POMC neurons and regulate their cellular activity.

    “Estrogens directly act on POMC neurons and regulate their cellular activity.”
  • ERα is abundantly expressed in the rodent brain in VMN, ARC, PVN, and the medial preoptic area; ERβ is found in the same hypothalamic nuclei but at significantly lower expression relative to ERα.

    “While ERα is abundantly expressed in the rodent brain in VMN and ARC, PVN, and the medial preoptic area, ERβ is found in the same hypothalamic nuclei, but ERβ expression is significantly lower relative to ERα [88, 91].”
  • Deletion of ER in POMC neurons in mice leads to hyperphagia without directly influencing energy expenditure or adipose tissue distribution.

    “Indeed, deletion of ER in POMC neurons in mice leads to hyperphagia without directly influencing energy expenditure or adipose tissue distribution [88].”

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.
