Contribution of time of day and the circadian clock to the heat stress responsive transcriptome in Arabidopsis. [PDF]

open access: yes, 2019
In Arabidopsis, a large subset of heat responsive genes exhibits diurnal or circadian oscillations. However, to what extent the dimension of time and/or the circadian clock contribute to heat stress responses remains largely unknown.

Disrupting circadian homeostasis of sympathetic signaling promotes tumor development in mice. [PDF]

open access: yesPLoS ONE, 2010
Cell proliferation in all rapidly renewing mammalian tissues follows a circadian rhythm that is often disrupted in advanced-stage tumors. Epidemiologic studies have revealed a clear link between disruption of circadian rhythms and cancer development in ...

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

open access: yes, 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,

In vitro and in vivo Phase Changes of the Mouse Circadian Clock by Oxidative Stress

open access: yesJournal of Circadian Rhythms, 2016
Mammalian circadian rhythms are governed by an endogenous circadian clock system, including the molecular clock works in each cell and tissue. Adaptation of the circadian clock to different environmental stimuli such as light, food, and stress is ...

A scenario of unhealthy life cycle: The role of circadian rhythms in health

open access: yesAging Medicine
Circadian rhythms are oscillations in physiology and behavior caused by the circadian regulator. Cryptochromes, Periods, and Bmal1 are circadian clock genes that have been linked to aging and cancer.

Circadian clock control of Nox4 and reactive oxygen species in the vasculature. [PDF]

open access: yesPLoS ONE, 2013
Recent studies have shown that circadian clock disruption is associated with pathological remodeling in the arterial structure and vascular stiffness.

Role of Sleep Restriction in Daily Rhythms of Expression of Hypothalamic Core Clock Genes in Mice

open access: yesCurrent Issues in Molecular Biology, 2022
Lack of sleep time is a menace to modern people, and it leads to chronic diseases and mental illnesses. Circadian processes control sleep, but little is known about how sleep affects the circadian system.

Diel pattern of circadian clock and storage protein gene expression in leaves and during seed filling in cowpea (Vigna unguiculata) [PDF]

open access: yes, 2018
Background Cowpea (Vigna unguiculata) is an important source of protein supply for animal and human nutrition. The major storage globulins VICILIN and LEGUMIN (LEG) are synthesized from several genes including LEGA, LEGB, LEGJ and CVC (CONVICILIN).

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Mutation of Arabidopsis SPLICEOSOMAL TIMEKEEPER LOCUS1 Causes Circadian Clock Defects [PDF]

open access: yes, 2012
The circadian clock plays a crucial role in coordinating plant metabolic and physiological functions with predictable environmental variables, such as dusk and dawn, while also modulating responses to biotic and abiotic challenges.
