Summary
Obstructive sleep apnea (OSA) disrupts the body's internal clock, impacting sleep-wake cycles and biological rhythms. Understanding circadian biology in OSA may lead to new diagnostic and treatment strategies using biomarkers.
Area of Science:
- Circadian Biology
- Sleep Medicine
- Molecular Physiology
Background:
- Obstructive sleep apnea (OSA) is linked to molecular clock dysregulation and disrupted 24-hour biological rhythms.
- Existing research shows interactions between the circadian clock and hypoxia-responsive pathways.
- Disrupted circadian rhythms can worsen OSA-related health issues, including cardiovascular and cognitive problems, even without OSA.
Purpose of the Study:
- To review current knowledge on circadian biology in patients with obstructive sleep apnea.
- To explore the potential of circadian biomarkers for diagnosing and treating OSA.
Main Methods:
- Literature review of studies on circadian rhythms and obstructive sleep apnea.
- Analysis of existing data on the relationship between molecular clock function and OSA pathophysiology.
- Examination of the clinical utility of proposed circadian biomarkers in OSA management.
Main Results:
- Circadian clock dysregulation is a significant factor in obstructive sleep apnea.
- Crosstalk between circadian and hypoxia pathways is evident in OSA.
- Disrupted circadian rhythms exacerbate OSA-associated comorbidities.
Conclusions:
- Understanding circadian biology is crucial for advancing OSA diagnosis and treatment.
- Circadian biomarkers show promise as novel clinical tools for OSA management.
- Further research into circadian interventions could improve patient outcomes in OSA.

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

4.2K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.

Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
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...

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
