Circadian Clocks in Fuel Harvesting and Energy Homeostasis
Body’s internal clocks in managing energy use and fuel processing
AI simplified
Abstract
Circadian systems optimize energy acquisition and storage in synchrony with the Earth's rotation.
- Circadian clocks in plants regulate gene expression for photosynthesis during the day and nitrogen fixation at night.
- In mammals, the core clock in the suprachiasmatic nucleus coordinates peripheral clocks with the light cycle.
- Local clocks in the endocrine pancreas are involved in insulin secretion, highlighting their role in maintaining organismal balance.
- Disruption of circadian rhythms may affect nuclear hormone receptor signaling and the regulation of metabolism.
- Genetic studies suggest significant interactions between circadian and metabolic systems, influencing fuel use during the sleep-wake cycle.
