Therapeutic implications of the circadian clock on skin function
Journal of Drugs in Dermatology : JDD
|February 11, 2014
Summary
The human body has a circadian clock that regulates daily processes. The skin also has its own clock, influencing aging, repair, and cancer, and optimizing drug delivery.
Area of Science:
- Chronobiology
- Dermatology
- Molecular Biology
Background:
- The human body possesses a central circadian clock regulating physiological processes.
- Peripheral tissues, including the skin, exhibit autonomous circadian oscillators.
- Skin's exposure to diurnal changes highlights its unique chronobiological relevance.
Purpose of the Study:
- To explore the significance of skin's circadian rhythm.
- To understand how circadian disruption impacts skin health.
- To determine the implications for dermatological treatments and drug delivery.
Main Methods:
- Review of current scientific literature on circadian rhythms and skin biology.
- Analysis of gene expression patterns related to skin circadian oscillators.
- Examination of studies on the effects of circadian disruption on skin aging and cancer development.
Main Results:
- Skin possesses autonomous circadian oscillators influenced by tissue-specific genes.
- Circadian dysfunction in skin is linked to accelerated aging, impaired repair, and increased skin cancer risk.
- Optimal timing of topical drug delivery can be enhanced by understanding skin circadian rhythms.
Conclusions:
- Understanding skin circadian biology is crucial for dermatology.
- Circadian disruption negatively affects skin health and therapeutic outcomes.
- Chronotherapeutic approaches in dermatology can improve treatment efficacy.

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

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.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Circadian Rhythms and Gene Regulation
3.4K
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...

Biological Clocks and Seasonal Responses

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.

Understanding Sleep
1.7K
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...

Management of Insomnia
785
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
