Circadian Control of the NAD + Salvage Pathway by CLOCK-SIRT1
Open accessAbstract
Circadian Oscillations: The 24-hour day-night cycle plays an important role in mammalian physiology and behavior and, as most travelers are well aware, there is an intimate link between our in-built circadian clocks and metabolic rhythms. This link is in part forged by the protein deacetylase SIRT1, which regulates the clock's molecular circuitry. SIRT1 uses as a cofactor the cellular metabolite NAD + , which is synthesized through a salvage pathway that includes the enzyme nicotinamide phosphoribosyltransferase (NAMPT) (see the Perspective by Wijnen ). Ramsey et al. (p. 651 ; published online 19 March) and Nakahata et al. (p. 654 , published online 12 March) now show that NAMPT and NAD + levels oscillate during the daily 24-hour cycle and that this oscillation is regulated by the circadian clock. Furthermore, the oscillations in NAD + modulate the activity of SIRT1 feeding back into the circadian clock.

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.
