Quantification of circadian rhythms in mammalian lung tissue snapshot data

open access: yesScientific Reports
Healthy mammalian cells have a circadian clock, a gene regulatory network that allows them to schedule their physiological processes to optimal times of the day.

Hepatic gene therapy rescues high-fat diet responses in circadian Clock mutant mice

open access: yesMolecular Metabolism, 2017
Objective: Circadian Clock gene mutant mice show dampened 24-h feeding rhythms and an increased sensitivity to high-fat diet (HFD) feeding. Restricting HFD access to the dark phase counteracts its obesogenic effect in wild-type mice.

Ontogeny of the circadian clock in Sarcophaga crassipalpis [PDF]

open access: yes, 2016
The timing of circadian rhythms is controlled by the rhythmic expression of clock genes in pacemaker neurons within the brain. Circadian gene expression and behavior can entrain to thermoperiod and photoperiod.

Circadian rhythmic kinase CK2α phosphorylates BMAL1 to regulate the mammalian clock [PDF]

open access: yes, 2008
Clock proteins govern circadian physiology and their function is regulated by a variety of signaling pathways. Here, we show that p45^PFK^, a previously reported circadian rhythmic kinase, corresponds to CK2[alpha].

O-GlcNAcylation of PERIOD regulates its interaction with CLOCK and timing of circadian transcriptional repression.

open access: yesPLoS Genetics, 2019
Circadian clocks coordinate time-of-day-specific metabolic and physiological processes to maximize organismal performance and fitness. In addition to light and temperature, which are regarded as strong zeitgebers for circadian clock entrainment ...

Circadian light-input pathways in Drosophila

open access: yesCommunicative & Integrative Biology, 2016
Light is the most important environmental cue to entrain the circadian clock in most animals. In the fruit fly Drosophila melanogaster, the light entrainment mechanisms of the clock have been well-studied.

EVOLUTION OF THE CIRCADIAN CLOCK IN EXTREME ENVIRONMENT: LESSONS FROM CAVEFISH. [PDF]

open access: yes, 2010
Evolution has been strongly influenced by the daily cycles of temperature and light imposed by the rotation of the Earth. Fascinating demonstrations of this are seen in extreme environments such as caves where some animals have remained completely ...

Exercise strengthens circadian clocks

open access: yesThe Journal of Physiology, 2012
We all know that exercise can increase the strength of our muscles. In this issue of The Journal of Physiology, new research by Schroeder and colleagues (2012) demonstrates that exercise can also have a big impact on the circadian system, a network of structures that regulate daily rhythms in physiology.
