Biological rhythms, including circadian rhythms, regulate sleep patterns. This review highlights circadian genes and their role in sleep regulation and associated diseases.
Area of Science:
- Chronobiology
- Sleep Science
- Genetics
Background:
- Biological rhythms are adaptations to environmental cycles, like the light/dark cycle.
- Circadian rhythms, approximately 24-hour cycles, influence physiological and behavioral changes.
- Human sleep, comprising NREM and REM phases, exhibits a circadian rhythm in its sleep/wake cycle.
Purpose of the Study:
- To review the role of circadian genes in regulating sleep.
- To highlight gene expression and biological pathways in sleep and circadian rhythm disorders.
Main Methods:
- Literature review of circadian genes and their function in sleep.
- Analysis of gene expression and pathways related to sleep and circadian rhythm disorders.
Main Results:
- Circadian genes are crucial regulators of sleep.
- Specific gene expressions and biological pathways are linked to sleep and circadian rhythm disorders.
Conclusions:
- Circadian rhythmicity is fundamental to biological organization and sleep regulation.
- Understanding circadian genes and pathways is vital for addressing sleep and circadian rhythm-associated diseases.

Sleep-Wake Cycles
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:
Understanding Sleep
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...
Stages of Sleep
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...
Management of Insomnia
Sleepwalking and Sleep Talking
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...
Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
