Understanding the role of chromatin remodeling in the regulation of circadian transcription in Drosophila. [PDF]

, 2015
Circadian clocks enable organisms to anticipate daily changes in the environment and coordinate temporal rhythms in physiology and behavior with the 24-h day-night cycle. The robust cycling of circadian gene expression is critical for proper timekeeping,

Voluntary exercise can strengthen the circadian system in aged mice [PDF]

, 2013
Consistent daily rhythms are important to healthy aging according to studies linking disrupted circadian rhythms with negative health impacts. We studied the effects of age and exercise on baseline circadian rhythms and on the circadian system's ability ...

Genome-wide association analyses of chronotype in 697,828 individuals provides insights into circadian rhythms

Nature Communications, 2019
Being a morning person is a behavioural indicator of a person’s underlying circadian rhythm. Using genome-wide data from 697,828 UK Biobank and 23andMe participants we increase the number of genetic loci associated with being a morning person from 24 to ...

Circadian Rhythms in the Pathogenesis and Treatment of Fatty Liver Disease.

Gastroenterology, 2020
Circadian clock proteins are endogenous timing mechanisms that control the transcription of hundreds of genes. Their integral role in coordinating metabolism has led to their scrutiny in a number of diseases, including NAFLD.

Programming effects of maternal stress on the circadian system of adult offspring

Experimental and Molecular Medicine, 2020
Circadian rhythms: Maternal stress can disrupt adult offspring’s biological clock When pregnant mothers are stressed, the fetus’s circadian rhythms are reprogrammed, increasing the risk of health complications later in life.

Circadian rhythm and neurodegenerative disorders

Brain Science Advances, 2020
The circadian clock controls daily rhythms in animal physiology, metabolism, and behavior, such as the sleep‐wake cycle. Disruption of circadian rhythms has been revealed in many diseases including neurodegenerative disorders.

Postnatal constant light compensates Cryptochrome1 and 2 double deficiency for disruption of circadian behavioral rhythms in mice under constant dark. [PDF]

PLoS ONE, 2013
Clock genes Cryptochrome (Cry1) and Cry2 are essential for expression of circadian rhythms in mice under constant darkness (DD). However, circadian rhythms in clock gene Per1 expression or clock protein PER2 are detected in the cultured suprachiasmatic ...

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.

Development of circadian oscillators in neurosphere cultures during adult neurogenesis. [PDF]

PLoS ONE, 2015
Circadian rhythms are common in many cell types but are reported to be lacking in embryonic stem cells. Recent studies have described possible interactions between the molecular mechanism of circadian clocks and the signaling pathways that regulate stem ...
