Abstract

The Clock gene is a core component of the circadian clock in mammals. We show here that serum levels of triglyceride and free fatty acid were significantly lower in circadian Clock mutant ICR than in wild-type control mice, whereas total cholesterol and glucose levels did not differ. Moreover, an increase in body weight induced by a high-fat diet was attenuated in homozygous Clock mutant mice. We also found that dietary fat absorption was extremely impaired in Clock mutant mice. Circadian expressions of cholecystokinin-A (CCK-A) receptor and lipase mRNAs were damped in the pancreas of Clock mutant mice. We therefore showed that a Clock mutation attenuates obesity induced by a high-fat diet in mice with an ICR background through impaired dietary fat absorption. Our results suggest that circadian clock molecules play an important role in lipid homeostasis in mammals.

  • Other Clock mutant mouse models show different metabolic results, including lack of obesity or weight loss despite lipid imbalance, suggesting the importance of genetic background.

    “However, different results have been reported in other Clock mutant mouse models as also lack of obesity or even weight loss, despite lipid imbalance, has been reported suggesting the importance of the genetic background when analyzing the metabolic effects of the Clock gene [13–16].”

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.
