Unique food-entrained circadian rhythm in cysteine414-alanine mutant mCRY1 transgenic mice
Food availability is a potent environmental cue that directs circadian locomotor activity in rodents. Daily scheduled restricted feeding (RF), in which the food available time is restricted for several hours each day, elicits anticipatory activity. This food-anticipatory activity (FAA) is controlled by a food-entrainable oscillator (FEO) that is distinct from the suprachiasmatic nucleus (SCN), ...

Daily scheduled feeding is a potent time cue that elicits anticipatory activity in rodents. This food-anticipatory activity (FAA) is controlled by a food-entrainable oscillator (FEO) that is distinct from light-entrained oscillators of the suprachiasmatic nucleus (SCN). Circadian rhythms within the SCN depend on transcription-translation feedback loops in which CLOCK protein is a key positive r...
متن کاملStochastic Simulation of the Entrained Circadian Rhythm
Circadian rhythms occur in almost all living things, providing an organism with a biological clock that gives an estimate of external time. The phenomenon of entrainment is a particularly interesting property of circadian rhythms in which the period of an organism’s circadian rhythm is adapted to match the natural oscillations of the environment. We applied the technique of stochastic simulatio...
متن کاملCircadian Clocks, Metabolism, and Food- Entrained Rhythms
The circadian clock is one of the most conserved systems in mammals. It is an important regulator of many biological processes, such as the sleep-wake cycle, hormone secretion, and body temperature, which can influence both cellular and organ-level metabolic functioning. At the molecular level, the circadian system consists of autoregulatory feedback loop that dictates the timing of behavioral ...
متن کاملCircadian Rhythms: Perturbing a Food-Entrained Clock
When food is scarce, a food-entrainable circadian clock coordinates mammalian activity rhythms with a predictable daily mealtime. Neural and molecular substrates of this circadian function have long eluded localization, but new studies suggest a critical role for a familiar circadian clock gene.
