The Significance of Circadian Organization for Longevity in the Golden Hamster

Hurd, Mark W., Ralph, Martin R.·1998·Journal of Biological Rhythms

Abstract

While functional roles for biological clocks have been demonstrated in organisms throughout phylogeny, the adaptive advantages of circadian organization per se are largely matters of conjecture. It is generally accepted, though without direct experimental evidence, that organisms derive primary benefits from the temporal organization of their physiology and behavior, as well as from the anticipation of daily changes in their environment and their own fluctuating physiological requirements. However, the consequences of circadian dysfunction that might demonstrate a primary adaptive advantage and explain the natural origins and apparent ubiquity of circadian systems have not been documented. The authors report that longevity in hamsters is decreased with a noninvasive disruption of rhythmicity and is increased in older animals given suprachiasmatic implants that restore higher amplitude rhythms. The results substantiate the importance of the temporal organization of physiology and behavior provided by the circadian clock to the health and longevity of an organism.

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.
