Circadian timing refers to the ability of ... Amplitude, precision and stability arise from the intermeshing of a negative feedback loop (in which rhythmically active clock factors oppose ...

This model was used to describe a negative feedback loop in the circadian clock system by considering the concentrations of mRNA and protein as variables. Numerical simulations demonstrated that ...

“Because glucose affects so many signalling pathways, it’s thought that glucose deficiency might challenge the feedback loops in the circadian clock and hinder its ability to maintain a constant ...

In addition to the sleep–wake cycle and cognitive functions such as learning and memory, intrinsic clocks determine nearly all circadian cycles in physiology, such as daily variation in blood ...

Circadian research has advanced so far that ... Together, they form complex feedback loops that accurately calibrate time. Although individual clock genes are not always the same across domains ...

But how could this gene influence the circadian rhythm ... They reasoned that by an inhibitory feedback loop, PER protein could prevent its own synthesis and thereby regulate its own level ...

Circadian rhythm explains why ... genes help influence these oscillations in the bugs, and explained the feedback loop that regulates the involved genes and myriad bodily rhythms.
