WebWhile we hypothesise that the cycled incubator temperature mirrors in vivo temperature cycles as a cue for synchronisation, in vivo epithelial clocks likely have further neurohormonal inputs from the suprachiasmatic nucleus and nutrients. 6 18 It remains unknown whether other disease mechanisms previously identified in the AEC-ALI model … WebAbstract. Endogenous circadian clock integrates cyclic signals of environment and daily and seasonal behaviors of organisms to achieve spatiotemporal synchronization, which greatly improves genetic diversity and fitness of species. This review addresses recent studies on the plant circadian system in the field of chronobiology, covering topics ...
WebAug 9, 2005 · Conclusions: We conclude that temperature synchronization of the circadian clock is a tissue-autonomous process that is able to override the arrhythmia-inducing effects of constant light. Our data suggest that it involves a cell-autonomous signal-transduction cascade from a thermal receptor to the circadian clock. WebNov 13, 2024 · The circadian clock can be entrained by environmental cues such as light, temperature and nutrient status to synchronize internal biological rhythms with surrounding environments.
