Plant 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
Frontiers 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.

Biological clocks in theory and experiments
, 2005 Eukaryotes and some prokaryotes have adapted to the 24 h day/night cycle by evolving circadian clocks. The circadian clock now controls 24-hour rhythms in very many aspects of metabolism, physiology and behaviour.

Thousands of oscillating LncRNAs in the mouse testis
Computational and Structural Biotechnology JournalThe 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 ...

Social information as an entrainment cue for the circadian clock [PDF]
Genetics and Molecular BiologyAnimals 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 ...

Adult Circadian behavior in Drosophila requires developmental expression of cycle, but not period
, 2011 Circadian clocks have evolved as internal time keeping mechanisms that allow anticipation of daily environmental changes and organization of a daily program of physiological and behavioral rhythms.

Arrhythmic perch hopping and rhythmic feeding of starlings in constant light: Separate circadian oscillators? [PDF]
, 1984 Perch hopping activity and food intake were recorded in starlings in different intensities of continuous illumination (LL), varying from 0.1 to 1000 lux. Circadian rhythmicity in perch hopping disappeared in 10 lux and all higher intensities. In contrast,

Entrainment of the Human Circadian Clock [PDF]
Cold Spring Harbor Symposia on Quantitative Biology, 2007 Humans are an excellent model system for studying entrainment of the circadian clock in the real world. Unlike the situation in laboratory experiments, entrainment under natural conditions is achieved by different external signals as well as by internal signals generated by multiple feedbacks within the system (e.g., behavior-dependent light and ...

Circadian rhythms in thrombosis and atherothrombotic events
Frontiers 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.
