Extension of a genetic network model by iterative experimentation and mathematical analysis [PDF]
Circadian clocks involve feedback loops that generate rhythmic expression of key genes. Molecular genetic studies in the higher plant Arabidopsis thaliana have revealed a complex clock network.

Circadian rhythms describe the near 24-hour oscillations observed across almost all biological processes on Earth. These rhythms serve to coordinate our behavior and physiology with the 24-hour light-dark environment in which we live. This article highlights normal circadian physiology and the disorders that can develop when those processes are ...

Circadian rhythms of ethylene emission in Arabidopsis [PDF]
Ethylene controls multiple physiological processes in plants, including cell elongation. Consequently, ethylene synthesis is regulated by internal and external signals.

Evening chronotypes experience poor sleep quality when taking classes with early starting times
Background and objective: The sleep-wake cycles of medical students are affected by their academic demands and class starting times. Despite their different sleep needs and characteristics (such as chronotype), all students must follow ...

Dopamine 2 Receptor Activation Entrains Circadian Clocks in Mouse Retinal Pigment Epithelium
Many of the physiological, cellular, and molecular rhythms that are present within the eye are under the control of circadian clocks. Experimental evidence suggests that the retinal circadian clock, or its output signals (e.g., dopamine and melatonin ...

Circadian gene variants and susceptibility to type 2 diabetes : a pilot study [PDF]
Background Disruption of endogenous circadian rhythms has been shown to increase the risk of developing type 2 diabetes, suggesting that circadian genes might play a role in determining disease susceptibility.
