Abstract

Adipocytes store excess energy in the form of triglycerides and signal the levels of stored energy to the brain. Here we show that adipocyte-specific deletion of Arntl (also known as Bmal1), a gene encoding a core molecular clock component, results in obesity in mice with a shift in the diurnal rhythm of food intake, a result that is not seen when the gene is disrupted in hepatocytes or pancreatic islets. Changes in the expression of hypothalamic neuropeptides that regulate appetite are consistent with feedback from the adipocyte to the central nervous system to time feeding behavior. Ablation of the adipocyte clock is associated with a reduced number of polyunsaturated fatty acids in adipocyte triglycerides. This difference between mutant and wild-type mice is reflected in the circulating concentrations of polyunsaturated fatty acids and nonesterified polyunsaturated fatty acids in hypothalamic neurons that regulate food intake. Thus, this study reveals a role for the adipocyte clock in the temporal organization of energy regulation, highlights timing as a modulator of the adipocyte-hypothalamic axis and shows the impact of timing of food intake on body weight.

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

  • CLOCK:BMAL1 transcription targets many genes in different cellular contexts across tissues.

    “Because CLOCK:BMAL1-mediated transcription targets a variety of genes in different cellular contexts across tissues (Janich et al., 2011; Marcheva et al., 2010; Paschos et al., 2012; Yu et al., 2013)”

  • The adipose clock regulates lipid storage and mobilization.

    “For example, the hepatic clock regulates fasting glycemic control and glucose clearance (8), the pancreatic clock regulates insulin secretion and its response to glucose (9-11), the adipose clock regulates lipid storage and mobilization (12,13), and the skeletal muscle clock regulates glucose uptake and metabolism (14).”

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.
