Abstract

The circadian clock synchronizes behavioral and physiological processes on a daily basis in anticipation of the light-dark cycle. In mammals, molecular clocks are present in both the central pacemaker neurons and in nearly all peripheral tissues. Clock transcription factors in metabolic tissues coordinate metabolic fuel utilization and storage with alternating periods of feeding and fasting corresponding to the rest-activity cycle. In vitro and in vivo biochemical approaches have led to the discovery of mechanisms underlying the interplay between the molecular clock and the metabolic networks. For example, recent studies have demonstrated that the circadian clock controls rhythmic synthesis of the cofactor nicotinamide adenine dinucleotide (NAD(+)) and activity of NAD(+)-dependent sirtuin deacetylase enzymes to regulate mitochondrial function across the circadian cycle. In this chapter, we review current state-of-the-art methods to analyze circadian cycles in mitochondrial bioenergetics, glycolysis, and nucleotide metabolism in both cell-based and animal models.

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

  • CLOCK-BMAL1 heterodimers drive rhythmic expression of nicotinamide phosphoribosyltransferase, a rate-limiting enzyme in the NAD+ salvage pathway; NAD+ acts as a cofactor for SIRT1, which regulates the activity of CLOCK-BMAL1.

    “For example, CLOCK-BMAL1 heterodimers drive rhythmic expression of nicotinamide phosphoribosyltransferase, which is a rate-limiting enzyme involved in the NAD+ salvage pathway; NAD+ acts as a cofactor for Sirtuin (SIRT1), which regulates the activity of CLOCK-BMAL1 among its other metabolic functions (23,24).”

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.
