[Molecular basis of circadian rhythms and principles of circadian disruption]
Abstract:
Current knowledge of core molecular mechanisms of circadian system is reviewed with intent look at consequences of pleiotropic effects of phase and amplitude disturbances in rhythmic expression of genome-transcriptome-proteome elements in development of desynchronized phenotypic functions. Multiple adverse implications of compromised circadian synchronization for health and longevity are discussed. Concept of extracircadian dissemination of output physiological functions as a general feature of phenotypic circadian disorder is PRESENTED.
Insights
Disruptions in the body's internal clock (circadian system) affect gene expression, leading to health problems and reduced lifespan. This review presents the concept of physiological functions spreading outside normal circadian rhythms in disorders.

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Factors Affecting Drug Biotransformation: Biological
Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...

The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...
