Circadian Rhythms in Urinary Functions: Possible Roles of Circadian Clocks? [PDF]

open access: yesInternational Neurourology Journal, 2011
Circadian clocks are the endogenous oscillators that harmonize a variety of physiological processes within the body. Although many urinary functions exhibit clear daily or circadian variation in diurnal humans and nocturnal rodents, the precise ...

Clock at the Core of Cancer Development

open access: yesBiology, 2021
To synchronize various biological processes with the day and night cycle, most organisms have developed circadian clocks. This evolutionarily conserved system is important in the temporal regulation of behavior, physiology and metabolism.

Cellular mechano-environment regulates the mammary circadian clock

open access: yesNature Communications, 2017
Circadian clocks regulate physiological and behavioural rhythms. Here, the authors show that the stiffness of the extracellular environment regulates circadian clocks in murine breast epithelium via Rho signalling, and explain how extracellular matrix ...

Keeping time in the dark: Potato diel and circadian rhythmic gene expression reveals tissue‐specific circadian clocks

open access: yesPlant Direct, 2022
The circadian clock is an internal molecular oscillator and coordinates numerous physiological processes through regulation of molecular pathways. Tissue‐specific clocks connected by mobile signals have previously been found to run at different speeds in

Circadian Oscillations in the Murine Preoptic Area Are Reset by Temperature, but Not Light

open access: yesFrontiers in Physiology, 2022
Mammals maintain their internal body temperature within a physiologically optimal range. This involves the regulation of core body temperature in response to changing environmental temperatures and a natural circadian oscillation of internal temperatures.

The circadian nature of mitochondrial biology

open access: yesFrontiers in Endocrinology, 2016
Circadian clocks orchestrate the daily changes in physiology and behavior of light sensitive organisms. These clocks measure about 24 h and tick in a self-sustained and cell-autonomous manner.

Circadian rhythms in thrombosis and atherothrombotic events

open access: yesFrontiers in Bioscience-Landmark, 2022
Biological circadian rhythms in living organisms are regulated by molecular clocks. Several of these clocks are present in blood vessels, peripheral tissues, and immune cells.

Circadian clocks: running on redox.

open access: yesCell, 2001
The circadian clock in all organisms is so intimately linked to light reception that it appears as if evolution has simply wired a timer into the mechanism that processes photic information. Several recent studies have provided new insights into the role of light input pathways in the circadian system of Arabidopsis.

Social information as an entrainment cue for the circadian clock [PDF]

open access: yesGenetics and Molecular Biology
Animals adapt to the daily changes in their environmental conditions by means of genetically encoded circadian clocks. These clocks, found throughout the tree of life, regulate diverse biological functions, and allow periodical changes in physiology and ...

Thousands of oscillating LncRNAs in the mouse testis

open access: yesComputational and Structural Biotechnology Journal
The long noncoding RNAs (lncRNAs) are involved in numerous fundamental biological processes, including circadian regulation. Although recent studies have revealed insights into the functions of lncRNAs, how the lncRNAs regulate circadian rhythms still ...
