Abstract

The circadian clock programs daily rhythms and coordinates multiple behavioral and physiological processes, including activity, sleep, feeding, and fuel homeostasis. Recent studies indicate that genetic alteration in the core molecular clock machinery can have pronounced effects on both peripheral and central metabolic regulatory signals. Many metabolic systems also cycle and may in turn affect function of clock genes and circadian systems. However, little is known about how alterations in energy balance affect the clock. Here we show that a high-fat diet in mice leads to changes in the period of the locomotor activity rhythm and alterations in the expression and cycling of canonical circadian clock genes, nuclear receptors that regulate clock transcription factors, and clock-controlled genes involved in fuel utilization in the hypothalamus, liver, and adipose tissue. These results indicate that consumption of a high-calorie diet alters the function of the mammalian circadian clock.

  • Circadian rhythms are endogenously generated in the suprachiasmatic nucleus of the hypothalamus by feedback loops of transcripts of a group of "core clock" genes, including the CLOCK gene.

    “Circadian rhythms are endogenously generated in the suprachiasmatic nucleus of the hypothalamus by feedback loops of transcripts of a group of “core clock” genes, including the CLOCK gene.40,41”
  • Time-keeping signals are passed on from the suprachiasmatic nucleus to oscillators in peripheral tissues also containing core clock genes.

    “Time-keeping signals are passed on from the suprachiasmatic nucleus to oscillators in peripheral tissues also containing core clock genes.”
  • A high-fat diet may alter the function of the circadian clock, with an altered period of the locomotor activity rhythm and changes in the rhythms of core clock genes in adipose and liver tissue.

    “Even a high-fat diet may alter the function of the circadian clock, with an altered period of the locomotor activity rhythm and changes in the rhythms of the core clock genes in adipose and liver tissue [35–40,49].”

    From Circadian control of glucose metabolism (2014) · cites this paper as [35]

  • Feeding mice a high fat diet alters the circadian period and attenuates the diurnal pattern of feeding behavior.

    “In concert with these findings, simply feeding mice a high fat diet alters the circadian period and attenuates the diurnal pattern of feeding behavior (Kohsaka et al., 2007).”

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.
