Post-translational modifications are as, or even more, important than transcriptional regulation to finely tune circadian rhythms ... to repress CLOCK and BMAL1, the whole cycle would take ...

Because the TMN is involved in the circadian rhythm ... transcription factors CLOCK and BMAL1. Do monoaminylated H3Q5 marks have a causal role in circadian rhythm? Zheng et al.

In the hypothalamus of your brain is a “master clock” that helps determine your circadian rhythm. This part of the brain is known as the suprachiasmatic nucleus (SCN). The SCN sends signals to ...

The body’s circadian rhythms are regulated by a “master clock ... green luciferase reporter to the mouse clock gene Per2, to watch both the SCN and peripheral clocks glow as they cycled. Changing the ...

Light is the strongest regulator of the central circadian rhythm. When light strikes a mammal’s eyes, it triggers an electrical impulse that activates neurons in the suprachiasmatic nucleus (SCN), the ...

This regular pulse was found to act as a kind of chemical metronome, helping to synchronize the neurons of the SCN and so indirectly impacting circadian rhythm and the sleep-wake cycle.

The circadian rhythm, our body’s internal clock, orchestrates the sleep-wake cycle. Exposure to natural light during the day ...
