昼夜节律钟协调生理和行为与24小时太阳日,以提供与外部环境的时间内稳态。驱动这些内在节律变化的分子钟是基于互锁的转录/翻译反馈回路,该回路与各种环境和代谢刺激相结合,以产生内部24小时计时。在这篇综述中,我们强调了最近的进展,我们了解的核心分子时钟,以及它如何利用不同的转录和转录后机制,赋予哺乳动物生理的时间控制。了解生物节律在整个身体中产生的方式可能为时间导向疗法提供途径,以改善健康和预防疾病。
Circadian clocks coordinate physiology and behavior with the 24-hour solar day to provide temporal homeostasis with the external environment. The molecular clocks that drive these intrinsic rhythmic changes are based on interlocked transcription/translation feedback loops that integrate with diverse environmental and metabolic stimuli to generate internal 24-hour timing. In this review we highlight recent advances in our understanding of the core molecular clock and how it utilizes diverse transcriptional and post-transcriptional mechanisms to impart temporal control onto mammalian physiology. Understanding the way in which biological rhythms are generated throughout the body may provide avenues for temporally-directed therapeutics to improve health and prevent disease.
