Coupled network of the circadian clocks: a driving force of rhythmic physiology

FEBS Letters, 2020
The circadian system is composed of coupled endogenous oscillators that allow living beings, including humans, to anticipate and adapt to daily changes in their environment.

Demyelination Regulates the Circadian Transcription Factor BMAL1 to Signal Adult Neural Stem Cells to Initiate Oligodendrogenesis

Cell Reports, 2020
Summary: Circadian clocks are endogenous oscillators that generate cell-autonomous rhythms that govern cellular processes and are synchronized by external cues in the local macro- and micro-environments.

Making Memories: Why Time Matters [PDF]

, 2018
In the last decade advances in human neuroscience have identified the critical importance of time in creating long-term memories. Circadian neuroscience has established biological time functions via cellular clocks regulated by photosensitive retinal ...

Rhythms of Locomotion Expressed by Limulus polyphemus, the American Horseshoe Crab: II. Relationship to Circadian Rhythms of Visual Sensitivity [PDF]

, 2008
In the laboratory, horseshoe crabs express a circadian rhythm of visual sensitivity as well as daily and circatidal rhythms of locomotion. The major goal of this investigation was to determine whether the circadian clock underlying changes in visual ...

Spectres of Clock Evolution: Past, Present, and Yet to Come

Frontiers in Physiology, 2022
Circadian clocks are phylogenetically widespread biological oscillators that allow organisms to entrain to environmental cycles and use their steady-state phase relationship to anticipate predictable daily phenomena – such as the light-dark transitions ...

SnapShot: Circadian Clock

Cell, 2017
Most creatures on this planet possess an ability to anticipate upcoming events in the environment, courtesy of their circadian clocks. This allows them to prepare for those changes instead of being caught by surprise, which could mean the difference between life and death. In this SnapShot, we describe the basics of how the clock ticks.

Rodent models for the analysis of tissue clock function in metabolic rhythms research [PDF]

, 2017
The circadian timing system consists on a distributed network of cellular clocks that together coordinate 24-h rhythms of physiology and behavior. Clock function and metabolism are tightly coupled, from the cellular to the organismal level.

Circadian rhythm and cell population growth [PDF]

, 2010
Molecular circadian clocks, that are found in all nucleated cells of mammals, are known to dictate rhythms of approximately 24 hours (circa diem) to many physiological processes.
