生物体中的许多行为和生理活动都表现出昼夜节律,使它们能够预测和准备生活环境中的日变化。通过这种方式,代谢过程与周期性的环境变化和行为周期保持一致,例如睡眠/清醒和禁食/进食周期。这种排列紊乱会显著增加代谢性疾病的风险。同时,生物钟接收来自环境的信号和来自代谢途径的反馈,并调整其活动和功能。越来越多的证据将生物钟与表观基因组调控联系起来。在这里,我们回顾了通过表观基因组编程和转录调控来理解生物钟和能量代谢之间的串扰的最新进展。
Many behaviors and physiological activities in living organisms display circadian rhythms, allowing them to anticipate and prepare for the diurnal changes in the living environment. In this way, metabolic processes are aligned with the periodic environmental changes and behavioral cycles, such as the sleep/wake and fasting/feeding cycles. Disturbances of this alignment significantly increase the risk of metabolic diseases. Meanwhile, the circadian clock receives signals from the environment and feedback from metabolic pathways, and adjusts its activity and function. Growing evidence connects the circadian clock with epigenomic regulators. Here we review the recent advances in understanding the crosstalk between the circadian clock and energy metabolism through epigenomic programming and transcriptional regulation.
