Biological functions of living things are regulated by the circadian rhythm, a 24-hour cycle.
Master clock in the hypothalamus is dependent on light-dark signals, while peripheral clock …

The circadian rhythm regulates the daily cycles of various physiological activities.
Accumulating evidences revealed that circadian rhythm plays an important role in regulating …

Circadian clocks that comprise clock genes exist throughout the body and control daily
physiological events. The central clock that dominates activity rhythms is entrained by …

Simple Summary Our daily life follows 24-h cycles in various biological functions, such as
sleep–wake and feeding/fasting cycles. These rhythms are regulated by endogenous clocks …

The mammalian circadian clock is vital for generating and coordinating metabolic rhythms.
Patterns in feeding behavior present organisms with an influx of nutrients at particular times …

Circadian rhythmicity that has been shaped by evolution over millions of years generates an
internal timing controlling the sleep–wake and metabolism cycles. The daily variations …

Circadian system is comprised by central circadian pacemaker and several peripheral
clocks that receive information from the external environment, synchronizing the circadian …

An endogenous circadian (∼ 24 h) clock regulates rhythmic processes of physiology,
metabolism and behavior in most living organisms. While able to free-run under constant …

Circadian rhythms are generated by the circadian clock, a self-sustained internal timing
system that exhibits 24-h rhythms in the body. In mammals, circadian rhythms are driven by …
