Abstract:
It has been well established that the circadian clock plays a crucial role in the regulation of almost every physiological process. It also plays a critical role in pathophysiological states including those of obesity and diabetes. Recent evidence has highlighted the potential for targeting the circadian clock as a potential drug target. New studies have also demonstrated the existence of "clock-independent effects" of the circadian proteins, leading to exciting new avenues of research in the circadian clock field in physiology. The goal of this review is to provide an introduction to and overview of the circadian clock in physiology, including mechanisms, targets, and role in disease states. The role of the circadian clocks in the regulation of the cardiovascular system, renal function, metabolism, the endocrine system, immune, and reproductive systems will be discussed.
Insights
The circadian clock regulates physiological processes and disease states like obesity and diabetes. Targeting circadian clock proteins offers new therapeutic avenues for various systems.
Area of Science:

- Endocrinology
Background:
- The circadian clock governs numerous physiological processes and is implicated in diseases such as obesity and diabetes.
- Emerging research reveals 'clock-independent effects' of circadian proteins, opening new research frontiers.
- Circadian clock dysregulation is linked to cardiovascular, metabolic, and immune system dysfunction.
Purpose of the Study:
- To provide a comprehensive overview of the circadian clock in physiology.
- To explore the mechanisms, targets, and disease relevance of circadian rhythms.
- To discuss the role of circadian clocks in regulating major organ systems.
Main Methods:
- Literature review synthesizing current research on circadian clock mechanisms.
- Analysis of studies investigating circadian clock proteins and their functions.
- Discussion of the impact of circadian clock on cardiovascular, renal, metabolic, endocrine, immune, and reproductive systems.
Main Results:
- The circadian clock is fundamental to regulating daily physiological rhythms.
- Circadian clock dysfunction contributes to the pathophysiology of metabolic and other diseases.
- Circadian proteins exhibit functions independent of the core clock machinery.
Conclusions:
- The circadian clock is a critical regulator of physiological homeostasis and disease.
