Circadian Desynchrony Promotes Metabolic Disruption in a Mouse Model of Shiftwork
Shiftwork is associated with adverse metabolic pathophysiology, and the rising incidence of shiftwork in modern societies is thought to contribute to the worldwide increase in obesity and metabolic syndrome. The underlying mechanisms are largely unknown, but may involve direct physiological effects of nocturnal light exposure, or indirect consequences of perturbed endogenous circadian clocks. T...
متن کاملShift Work or Food Intake during the Rest Phase Promotes Metabolic Disruption and Desynchrony of Liver Genes in Male Rats
In the liver, clock genes are proposed to drive metabolic rhythms. These gene rhythms are driven by the suprachiasmatic nucleus (SCN) mainly by food intake and via autonomic and hormonal pathways. Forced activity during the normal rest phase, induces also food intake, thus neglecting the signals of the SCN, leading to conflicting time signals to target tissues of the SCN. The present study expl...
متن کاملShiftwork and metabolic dysfunction.
Many of the health problems that are more prevalent among shiftworkers are thought to be linked to their heightened susceptibility to metabolic syndrome, i.e., the association of even moderate degrees of visceral obesity, dyslipidemia, abnormal blood pressure, and serum glucose levels in the same individual. Although previous studies have identified associations between shiftwork and metabolic ...
متن کاملDisruption of normal circadian clock function in a mouse model of tauopathy
Disruption of normal circadian rhythm physiology is associated with neurodegenerative disease, which can lead to symptoms such as altered sleep cycles. In Alzheimer's disease (AD), circadian dysfunction has been attributed to β-amyloidosis. However, it is unclear whether tauopathy, another AD-associated neuropathology, can disrupt the circadian clock. We have evaluated the status of the circadi...
متن کاملCircadian desynchrony and metabolic dysfunction; did light pollution make us fat?
Circadian rhythms are daily oscillations in physiology and behaviour that recur with a period of 24h, and that are entrained by the daily photoperiod. The cycle of sunrise and sunset provided a reliable time cue for many thousands of years, until the advent of artificial lighting disrupted the entrainment of human circadian rhythms to the solar photoperiod. Circadian desynchrony (CD) occurs whe...
