Summary
Circadian rhythms, governed by the molecular clock, impact human health, disease, and metabolism. Understanding these biological rhythms offers new therapeutic targets and personalized disease prevention strategies.
Area of Science:
- Chronobiology
- Molecular Biology
- Physiology
Background:
- The discovery of the circadian clock laid the genetic groundwork for understanding behavior.
- Circadian rhythms offer molecular insights into disease mechanisms and physiological processes.
- Synchronization of internal clocks influences physiological systems and homeostatic regulation.
Purpose of the Study:
- To explore the role of the rhythmical epigenome in regulating circadian transcription.
- To investigate the interplay between circadian rhythms, metabolism, and human health.
- To highlight the potential of circadian biology in disease diagnosis and therapeutic optimization.
Main Methods:
- Analysis of the rhythmical epigenome as a central regulator of circadian transcription.
- Examination of interactions between the endogenous circadian system and physiological functions (e.g., blood pressure, sleep, obesity).
- Review of how lifestyle factors (diet, sleep) influence circadian rhythms.
Main Results:
- The rhythmical epigenome imposes oscillations on biological systems, influencing metabolism within 24-hour cycles.
- Circadian rhythms are intrinsically linked to blood pressure, sleep, obesity, and postural control.
- Circadian rhythmicity collectively drives metabolic activities, but is also influenced by external factors.
Conclusions:
- Human health is fundamentally dependent on circadian rhythmicity.
- Understanding the circadian clock-disease relationship can guide treatment timing and identify novel therapeutic targets.
- The synergy between circadian rhythms and metabolism provides a basis for personalized disease analysis and prevention.

02:19Circadian Rhythms and Gene Regulation
4.0K
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...

01:37Epigenetic Regulation
3.0K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

01:20Gene-Environment Interactions
244
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

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.

01:11Understanding Sleep
216
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...

02:27Background and Environment Affect Phenotype
6.4K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
