Summary
Biological clocks coordinate body functions with daily cycles. Understanding how these clocks connect across tissues is crucial for preventing diseases linked to circadian disruption in modern life.
Area of Science:
- Chronobiology
- Physiology
- Molecular Biology
Background:
- Circadian clocks are endogenous oscillators synchronizing physiology with environmental cycles.
- In complex organisms, cellular clocks form an integrated, organism-wide system.
- Disruptions in circadian timing are linked to metabolic syndrome, cancer, and other diseases.
Purpose of the Study:
- To elucidate the physiological circuits enabling coherence among biological clocks.
- To understand how tissue-level clock coordination impacts organismal health.
- To identify potential therapeutic targets for circadian rhythm disruption.
Main Methods:
- Review of recent advances in understanding circadian clock connectivity.
- Analysis of molecular and anatomical mechanisms of clock integration.
- Exploration of the physiological consequences of circadian misalignment.
Main Results:
- Significant progress has been made in understanding how cellular clocks connect across tissues.
- Circadian coherence is essential for physiological coordination.
- Modern societal factors frequently impose circadian misalignment.
Conclusions:
- Understanding the physiological circuits of circadian coherence is vital for human health.
- Elucidating these pathways offers opportunities for disease prevention and treatment.
- Restoring circadian alignment may mitigate risks associated with metabolic and other diseases.

02:19Circadian Rhythms and Gene Regulation
4.3K
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...

02:45Biological Clocks and Seasonal Responses
40.8K
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.

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...

01:11Understanding Sleep
1.1K
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...

01:16What is Homeostasis?
50.5K
Maintaining homeostasis requires that the body continuously maintain its internal conditions. Each physiological condition has a particular set point, from body temperature to blood pressure to levels of certain nutrients. A set point is the physiological value around which the normal range fluctuates. A normal range is a restricted set of values that is optimally healthful and stable. For example, the set point for normal human body temperature is approximately 37°C (98.6°F).

01:10An Overview of the Endocrine System
11.5K
The endocrine system, a complex network of glands, orchestrates physiological balance within the body through the production and secretion of hormones. These hormones are chemical messengers in intercellular communication, acting as conduits between the secretory cells and distant target sites. They traverse the circulatory system by being released into the extracellular fluid, and their impact is specific to cells possessing receptors for a particular hormone.
