Disturbance of the circadian clock by sleep deprivation has been proposed to be involved in the regulation of inflammation. However, the underlying mechanism of circadian oscillator components in regulating the pro-inflammatory process during sleep deprivation remains poorly understood. Using a
In the present study, we aimed to investigate the preventive effects of 4-hydroxychalcone (4HCH) on resistant hypertension. We used cryptochrome-null mice, which characteristically show high plasma aldosterone levels, inflammation, and renal injury. The cryptochrome-null mice received high-salt
We have recently found that the temperature variability (TV) in the day-night cycle may predict the mean intracranial pressure in the following 24 h (ICP24) in subarachnoid hemorrhage (SAH) patients under multimodality monitoring, sedation, and hypothermia (<35°C). Specifically, we found that ICP24
The mammalian circadian clock coordinates various physiological activities with environmental cues to achieve optimal adaptation. The clock manifests oscillations of key clock proteins, which are under dynamic control at multiple post-translational levels. As a major post-translational regulator,
The mammalian clock genes, Period and Cryptochrome (Cry), regulate circadian rhythm. We show that circadian rhythmicity and rhythmic expression of Period in the nuclei of inflammatory synovial cells and spleen cells are disturbed in mouse models of experimental arthritis. Expressions of other clock
This study aims to explore the effect and mechanism of Jiao-tai-wan (JTW) on systemic and tissue-specific inflammation and insulin resistance in obesity-resistant (OR) rats with chronic partial sleep deprivation (PSD). OR rats with PSD were orally given JTW and Estazolam for 4 weeks. The amount of
BACKGROUND
Jiao-Tai-Wan (JTW), composed of Rhizome Coptidis and Cortex Cinnamomi, is a classical traditional Chinese prescription for treating insomnia. Several in vivo studies have concluded that JTW could exert its therapeutical effect in insomnia rats. However, the specific mechanism is still
The clinical symptoms of rheumatoid arthritis (RA) present with circadian variation, with joint stiffness and pain more prominent in the early morning. The mammalian clock genes, which include circadian locomotor output cycles kaput, brain and muscle Arnt-like protein 1, period and cryptochrome,
There is strong diurnal variation in the symptoms and severity of chronic inflammatory diseases, such as rheumatoid arthritis. In addition, disruption of the circadian clock is an aggravating factor associated with a range of human inflammatory diseases. To investigate mechanistic links between the
Chronic sleep deprivation perturbs the circadian clock and increases susceptibility to diseases such as diabetes, obesity, and cancer. Increased inflammation is one of the common underlying mechanisms of these diseases, thus raising a hypothesis that circadian-oscillator components may regulate
A single injection of LPS produced low-grade neuroinflammation leading to Parkinson's disease (PD) in mice several months later. Whether such a phenomenon occurs in rats and whether such low-grade neuroinflammation would aggravate rotenone (ROT) neurotoxicity and disrupts circadian clock
OBJECTIVE
To explore the effect and mechanism of Jiaotai Pill (, JTW) on intestinal mucosal damage in rats with chronic partial sleep deprivation (PSD).
METHODS
Obesity resistant (OR) rats were selected, and underwent 4 h PSD by being exposed to environmental noise for 4 weeks. During the whole PSD
Resetting of the circadian clocks involves the heat shock pathway. Cryptochromes as the actual repressors take care of circadian alignment, and in addition they link the circadian clocks to temperature responses, metabolic homeostasis, and sleep homeostasis. In contrast, circadian misalignment
OBJECTIVE
To study the effect of tumour necrosis factor (TNF)-α, responsible for the inflammation and circadian rhythm of rheumatoid arthritis (RA), on the expression of circadian clock genes in primary cultured human rheumatoid synovial cells.
METHODS
The expression of circadian clock genes,
Both incidence and death rate due to liver cancer have increased in the United States. Higher consumption of lycopene-rich tomato and tomato products is associated with a decreased risk of cancers. β-Carotene-15, 15'-oxygenase (BCO1), and β-carotene-9', 10'-oxygenase (BCO2) cleave lycopene to
