The Circadian Clock and Viral Infections [PDF]

Journal of Biological Rhythms, 2020
The circadian clock controls several aspects of mammalian physiology and orchestrates the daily oscillations of biological processes and behavior. Our circadian rhythms are driven by an endogenous central clock in the brain that synchronizes with clocks in peripheral tissues, thereby regulating our immune system and the severity of infections.

Importance of circadian timing for aging and longevity

Nature Communications, 2021
Circadian clocks link physiologic processes to environmental conditions and a mismatch between internal and external rhythms has negative effects on organismal health.

The circadian control of eating

Journal of Behavior and Feeding, 2021
Eating is a complex behavior that is primarily governed by energy homeostasis and modulated by hedonic cues. Eating is also structured in time, due to circadian clocks that control its daily rhythmicity.

Robustness from flexibility in the fungal circadian clock [PDF]

, 2010
Background Robustness is a central property of living systems, enabling function to be maintained against environmental perturbations. A key challenge is to identify the structures in biological circuits that confer system-level properties such as ...

Towards the discovery of novel molecular clocks in Prokaryotes [PDF]

, 2023
Diel cycle is of enormous biological importance as it imposes daily oscillation in environmental conditions, which temporally structures most ecosystems. Organisms developed biological time-keeping mechanisms –

The circadian clock and asthma [PDF]

Thorax, 2013
It is characteristic of asthma that symptoms worsen overnight, particularly in the early hours of the morning. Nocturnal symptoms in asthma are common and are an important indicator for escalation of treatment. An extensive body of research has demonstrated that nocturnal symptoms of cough and dyspnea are accompanied by circadian variations in airway ...

Light and circadian regulation of clock components aids flexible responses to environmental signals [PDF]

, 2014
The circadian clock measures time across a 24 h period, increasing fitness by phasing biological processes to the most appropriate time of day. The interlocking feedback loop mechanism of the clock is conserved across species; however, the number of ...

FLOWERING LOCUS C -dependent and -independent regulation of the circadian clock by the autonomous and vernalization pathways [PDF]

, 2006
Background The circadian system drives pervasive biological rhythms in plants. Circadian clocks integrate endogenous timing information with environmental signals, in order to match rhythmic outputs to the local day/night cycle.

The circadian clock and behavior

Behavioural Brain Research, 2001
Temporal organization is a fundamental feature of all living systems. Timing is essential for development, growth and differentiation and in the mature organism, it is essential to maintain normal physiology and behavior. The biological entity that permits an organism's day/night organization is the circadian system.

Circadian Clocks: Translation Lost [PDF]

Current Biology, 2005
One of the big questions in biological rhythms research is how a stable and precise circa-24 hour oscillation is generated on the molecular level. While increasing complexity seemed to be the key, a recent report suggests that circa-24 hour rhythms can be generated by just four molecules incubated in a test tube.
