Abstract

Sleep deprivation, shift work, and jet lag all disrupt normal biological rhythms and have major impacts on health; however, circadian disorganization has never been shown as a causal risk factor in organ disease. We now demonstrate devastating effects of rhythm disorganization on cardiovascular and renal integrity and that interventions based on circadian principles prevent disease pathology caused by a short-period mutation ( tau) of the circadian system in hamsters. The point mutation in the circadian regulatory gene, casein kinase-1ε, produces early onset circadian entrainment with fragmented patterns of behavior in +/ tau heterozygotes. Animals die at a younger age with cardiomyopathy, extensive fibrosis, and severely impaired contractility; they also have severe renal disease with proteinuria, tubular dilation, and cellular apoptosis. On light cycles appropriate for their genotype (22 h), cyclic behavioral patterns are normalized, cardiorenal phenotype is reversed, and hearts and kidneys show normal structure and function. Moreover, hypertrophy does not develop in animals whose suprachiasmatic nucleus was ablated as young adults. Circadian organization therefore is critical for normal health and longevity, whereas chronic global asynchrony is implicated in the etiology of cardiac and renal disease.

  • Disruptions of the molecular clock in animals cause significant cardiovascular disease.

    “Disruptions of the molecular clock in animals cause significant CV disease (61), exemplifying the importance of these rhythms.”

  • Cardiomyopathy was observed in hamsters whose internal circadian clock period did not match the external 24-hour light cycle (i.e., 20-hour period due to the tau mutation).

    “Cardiomyopathy was observed in hamsters whose internal circadian clock period did not match the external 24-hour light cycle (i.e., 20-hour period due to the tau mutation) (61,144).”

    From Role of the circadian system in cardiovascular disease (2018) · cites this paper as [61]

  • Tau mutant hamsters living on a 24-h light/dark cycle have a shorter life span than wild-type hamsters.

    “Tau mutant hamsters have a shorter life span and have cardiomyopathy, fibrosis, and impaired heart contractility when they live on a 24-h light/dark cycle which is beyond their circadian timing system’s range of entrainment and thus causes the animal’s behavioral cycle and biological timing system to be out of phase (i.e., desynchronized; Martino et al., 2008).”

  • When Tau mutant hamsters are placed in 22-h light/dark cycles similar to their endogenous circadian period, the pathological changes are largely reversed.

    “Remarkably, when Tau mutant hamsters are placed in 22-h light/dark cycles, similar to their endogenous circadian period, these pathological changes are largely reversed.”

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.
