Watching the hands of the Arabidopsis biological clock [PDF]

open access: yes, 2001
Oligonucleotide and cDNA microarrays have been used to analyse the mRNA levels of 8,000 genes in Arabidopsis thaliana throughout the day/night cycle. Genes involved in signal transduction and in various metabolic pathways were found to be coordinately ...

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

open access: yes, 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 ...

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

open access: yesPLoS 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 Rhythms in Immunity [PDF]

open access: yesCurrent Allergy and Asthma Reports, 2020
This review is focused on the existing evidence for circadian control of innate and adaptive immune responses to provide a framework for evaluating the contributions of diurnal rhythms to control of infections and pathogenesis of disease.Circadian rhythms driven by cell-autonomous biological clocks are central to innate and adaptive immune responses ...

Diurnal rhythms in neurexins transcripts and inhibitory/excitatory synapse scaffold proteins in the biological clock [PDF]

open access: yes, 2012
The neurexin genes (NRXN1/2/3) encode two families (α and β) of highly polymorphic presynaptic proteins that are involved in excitatory/inhibitory synaptic balance.

A cellular model for human daily behaviour [PDF]

open access: yes, 2010
All the biochemical, physiological or behavioural processes whose period is about 24 hours possess a circadian rhythm. In mammals circadian rhythms control almost all aspects of human daily behaviour and physiology.

Serotonin and corticosterone rhythms in mice exposed to cigarette smoke and in patients with COPD:implication for COPD-associated neuropathogenesis [PDF]

open access: yes, 2014
The circadian timing system controls daily rhythms of physiology and behavior, and disruption of clock function can trigger stressful life events. Daily exposure to cigarette smoke (CS) can lead to alteration in diverse biological and physiological ...

Circadian rhythm and neurodegenerative disorders

open access: yesBrain 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.
