Abstract
Circadian control affects numerous molecular and cellular processes in mammals.
- Most physiological processes in mammals show rhythmicity aligned with daily environmental changes.
- A cell-autonomous clock gene network drives the rhythmic expression of genes across nearly all body cells.
- Pharmacology and toxicology also exhibit time-of-day variations, influencing drug effects on the body.
- Genome-wide studies and mathematical modeling have enhanced understanding of these nonlinear physiological aspects.
- Integrative approaches may lead to new strategies for chronotherapeutic treatments and insights into circadian system restoration.
