人类的早/晚偏好最近被报道与Clock基因3 '侧区多态性有关,Clock基因是第一个被发现的哺乳动物生物钟基因。我们记录了Jcl:ICR遗传背景和Clock突变纯合子(Jcl:ICR上的Cl/Cl)小鼠48小时的体温、自发活动、脑电图和肌电图。在野生型和Jcl:ICR的Cl/Cl中,体温、活动、清醒和睡眠完全跟随LD周期。然而,Jcl:ICR上Cl/Cl的体温、活动和清醒时间节律相比野生型延迟约2小时。本研究为人类早/晚偏好与生物钟系统分子基础的密切关系提供了进一步证据,并提示Jcl:ICR上的Cl/Cl可用于人类早/晚偏好的动物模型。
Human morning/evening preferences has recently been reported to be associated with polymorphism of the 3′ flanking region of the Clock gene, which was the first identified mammalian circadian clock gene. We recorded body temperature, spontaneous activity, electroencephalogram and electromyogram for 48 h in mice with Jcl:ICR genetic background and homozygous for the Clock mutation (Cl/Cl on Jcl:ICR). In both wild-type and Cl/Cl on Jcl:ICR, body temperature, activity, wake and sleep were completely entrained to LD cycle. However, phases of the rhythm for body temperature, activity and wake duration in the Cl/Cl on Jcl:ICR were about 2 h delayed in comparison with the wild-type. This study has provided further evidence on the close relationship between human morning/evening preference and the molecular basis of circadian clock system, and has suggested that Cl/Cl on Jcl:ICR is useful for an animal model for human morning/evening preference.
