Our results show that transcription is not required for circadian oscillations in humans, and that non-transcriptional events seem to be sufficient to sustain cellular circadian rhythms. Using red blood cells, we found that peroxiredoxins, highly conserved antioxidant proteins, undergo 鈭 24-hour ...
in this daily schedule. For example, biologists have observed that birds exposed to artificial light for a long time sometimes build nests in the fall instead of the spring. In humans who travel long distances by air, the local time of day no longer matches the body's internal clock, ...
circadian clock 生物钟；昼夜节律生物钟；昼夜节律钟；昼夜时钟 In humans melatonin levels rise at night, in response to darkness and cues from the circadian clock.人类的褪黑激素水平在夜晚上升，以响应黑暗和昼夜节律钟发出的信号。很高兴第一时间为您解答，祝学习进步如有问题请及时追问，谢谢~...
Key roles of the circadian clock in diverse biological processes Circadian rhythms, also known as the circadian clock, are highly-conserved and self-sustaining timing mechanisms within living organisms, which oscillate diurnally over 24 h. It is implicated in the regulation of a diverse array of ...

Like most creatures on earth, humans come equipped with a circadian clock (生物钟), a roughly 24-hour timer that keeps our sleep patterns in line with our planet. Even though the average adult needs eight hours of sleep per night, there are“short sleepers”, who need far less, and morn...
