Associations of clock genes polymorphisms with soft tissue sarcoma susceptibility and prognosis [PDF]

open access: yes, 2018
BACKGROUND: Dysfunction of the circadian clock and polymorphisms of some circadian genes have been linked to cancer development and progression. We investigated the relationship between circadian genes germline variation and susceptibility or prognosis ...

Dual‐Crosslinked Betaine‐Based Amphiphilic Hydrogel as a Promising Vitreous Substitute: Anti‐Adhesion, Anti‐Fouling, and Anti‐Cell Proliferation

open access: yesAdvanced Science, EarlyView.
A novel multiple cross‐linked betaine‐type amphiphilic polymer hydrogels are developed via in situ free radical copolymerization. The resultant formation, named P(SBMA‐co‐AANa) hydrogel, functions as a vitreous substitute and demonstrates superior performance in optical properties, support capacity, and biocompatibility on a vitrectomized rabbit model.

Circadian Rhythm in Yeast [PDF]

open access: yes, 2012
Circadian rhythms are found in a variety of organisms and are involved in controlling activity of the organism. However, a circadian rhythm for yeast has not been discovered yet.

Circadian Timing of Food Intake Contributes to Weight Gain [PDF]

open access: yes, 2009
Studies of body weight regulation have focused almost entirely on caloric intake and energy expenditure. However, a number of recent studies in animals linking energy regulation and the circadian clock at the molecular, physiological, and behavioral ...

Circadian patterns of breathing [PDF]

open access: yesRespiratory Research, 2001
In the rat, a mostly nocturnal animal, activity, body temperature and metabolic rate increase during the dark hours of the day. Since all these variables are known to influence breathing, it is expected that also pulmonary ventilation (VE) will present a circadian pattern.

The DEC2‐SCN2A Axis is Essential for the Anticonvulsant Effects of Cannabidiol by Modulating Neuronal Plasticity

open access: yesAdvanced Science, EarlyView.
This study identifies DEC2 as a critical transcriptional repressor of Scn2a that directly binds E‐box motifs in its promoter to regulate neuronal plasticity and epileptogenesis. Functional manipulation of DEC2 alters seizure susceptibility in vivo. Cannabidiol enhances this repression, unveiling a novel DEC2‐SCN2A axis underlying its anticonvulsant ...

Accurate timekeeping is controlled by a cycling activator in Arabidopsis. [PDF]

open access: yes, 2013
Transcriptional feedback loops are key to circadian clock function in many organisms. Current models of the Arabidopsis circadian network consist of several coupled feedback loops composed almost exclusively of transcriptional repressors.

A Web of Circadian Pacemakers [PDF]

open access: yesCell, 2002
The mammalian circadian timing system is composed of almost as many individual clocks as there are cells. These countless oscillators have to be synchronized by a central pacemaker to coordinate temporal physiology and behavior. Recently, there has been some progress in understanding the relationship and communication mechanisms between central and ...

A Peripheral Mechanism of Depression: Disturbed Intestinal Epithelial Per2 Gene Expression Causes Depressive Behaviors in Mice with Circadian Rhythm Disruption via Gut Barrier Damage and Microbiota Dysbiosis

open access: yesAdvanced Science, EarlyView.
Circardian rhythm disorder (CRD) causes abnormal expression of intestinal Period 2 (Per2) gene, which compromising intestinal barrier integrity and altering the gut microenvironment. Microbiota dysbiosis and aberrant metabolites production drive central inflammation, impair neurogenesis, and promote functional deficits, ultimately facilitating the ...

Circadian oscillators in the epithalamus

open access: yesNeuroscience, 2010
The habenula complex is implicated in a range of cognitive, emotional and reproductive behaviors, and recently this epithalamic structure was suggested to be a component of the brain's circadian system. Circadian timekeeping is driven in cells by the cyclical activity of core clock genes and proteins such as per2/PER2. There are currently no reports of
