摘要
时间生物学主要研究生物节律的产生及生物钟的运行机制,2017年诺贝尔生理或医学奖的颁布再次引发人们对该领域诸多科学问题的高度关注。生物钟与日月运行引起的环境信号周期性保持同步,有利于生物节律的相位和组织稳态的精确维持。本文介绍了生物节律现象的早期研究及随后生物钟理论体系建立的发展简史,并结合2017年诺贝尔生理或医学奖的解读阐述了果蝇生物钟基因的发现与分子调控机理,进而简单归纳当前时间生物学领域的前沿科学问题,阐明生物钟研究的意义。
Chronobiology is a field of biology that examines the generation of biological rhythms in various creatures and in many parts of body,and their adaptive fitness to solar-and lunar-related periodic phenomena.The synchronization of internal circadian clocks with external timing signals confers accurate phase response and tissue homeostasis.Herein we state a series of studies on circadian rhythms and introduce the brief history of chronobiology.We also present a detailed timeline of the discoveries on molecular mechanisms controlling circadian rhythm in Drosophila,which was awarded the2017Nobel Prize in Physiology or Medicine.The latest findings and new perspectives are further summarized to indicate the significance of circadian research.
