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 ...

Watching the hands of the Arabidopsis biological clock [PDF]

, 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 ...

Circadian rhythms and diabetes [PDF]

Journal of Diabetes Investigation, 2011
All free‐living organisms are regulated by the 24‐h light and dark cycle produced by Earth’s rotation. In mammals, circadian rhythms are indispensble for the regulation of physiological and biochemical processes in the body. In 1972, the suprachiasmatic nucleus was shown to be required for daily rhythms in animal behavior1.

Circadian rhythms of ethylene emission in Arabidopsis [PDF]

, 2004
Ethylene controls multiple physiological processes in plants, including cell elongation. Consequently, ethylene synthesis is regulated by internal and external signals.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

The role of the circadian rhythms in critical illness with a focus on acute pancreatitis

Heliyon, 2023
Circadian rhythms are responsible for governing various physiological processes, including hormone secretion, immune responses, metabolism, and the sleep/wake cycle.

The contributions of interlocking loops and extensive nonlinearity to the properties of circadian clock models [PDF]

, 2010
Sensitivity and robustness are essential properties of circadian clock systems, enabling them to respond to the environment but resist noisy variations. These properties should be recapitulated in computational models of the circadian clock.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

The Role of TASK-3 Two-Pore Domain Potassium Channels in the Entrainment of Mammalian Circadian Rhythms [PDF]

, 2014
In mammals light is the principal timing cue for alignment of physiology to the external environment. Illumination from the unrelenting 24-hour day-night cycle enters the biological system and is communicated to the master pacemaker, the suprachiasmatic
