Abstract

Circadian rhythms orchestrate a wide range of molecular, physiological, and behavioral processes.

  • Circadian clocks consist of a hierarchical network of central and peripheral clocks that synchronize daily rhythms.
  • Peripheral clock functioning is influenced by signals from the central clock, hormones, feeding, and external cues.
  • Disruption of circadian rhythms is associated with negative impacts on human health and can lead to various disorders.
  • Pharmacokinetics and pharmacodynamics are subject to circadian oscillations, affecting the efficacy and toxicity of therapeutic agents.
  • Modeling approaches have been utilized to explore circadian biology, optimize drug dosing times, and understand pharmacological effects on clock mechanisms.
