Summary
Peripheral tissue communication synchronizes nutrient processing with feeding times, preventing metabolic disease. This coordination relies on the metabolic clock and hormonal signals, crucial for maintaining overall metabolic homeostasis.
Area of Science:
- Endocrinology
- Metabolism
- Chronobiology
Background:
- Peripheral tissue cross-talk is vital for coordinating nutrient intake and disposition.
- Disruptions in this coordination can lead to metabolic diseases.
- The metabolic clock integrates signals from various tissues.
Purpose of the Study:
- To review interactions between key peripheral tissues forming the metabolic clock.
- To highlight the role of circadian rhythms in metabolic regulation.
- To emphasize the importance of synchronized peripheral metabolic pathways.
Main Methods:
- Review of multiple mini-reviews published in Endocrinology (2020-2021).
- Analysis of interactions between gastrointestinal tract, microbiome, pancreatic beta cells, liver, and adipose tissues.
- Examination of hormonal and metabolic feedback signals.
Main Results:
- Peripheral tissues communicate via hormonal and metabolic feedback loops.
- These signals synchronize metabolic pathways with feeding times.
- The circadian clock is critical for maintaining metabolic homeostasis.
Conclusions:
- Coordinated communication among peripheral tissues is essential for metabolic health.
- The circadian clock plays a critical role in synchronizing nutrient metabolism.
- Maintaining metabolic homeostasis depends on synchronized peripheral tissue function.

01:19Regulation of Metabolism
10.4K
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Metabolism encompasses all biochemical reactions in a living organism, facilitating both the breakdown and synthesis of biomolecules. These metabolic processes are categorized into catabolic and anabolic pathways, which operate in a coordinated manner to ensure energy balance and cellular function.Catabolic Pathways and Energy ReleaseCatabolic pathways involve the breakdown of complex macromolecules such as carbohydrates, lipids, and proteins into smaller structures like monosaccharides, fatty...

01:02Glucose Homeostasis: Regulation of Blood Glucose
2.8K
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

01:16What is Homeostasis?
48.8K
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).

Homeostasis is the maintenance of a stable internal environment within the body, which is crucial for the proper functioning of cells, tissues, organs, and organ systems. The body has various control mechanisms that work together to regulate various physiological parameters such as temperature, blood pressure, pH balance, and fluid balance, to name a few. These control mechanisms are based on feedback loops that can be either positive or negative.
However, sometimes these feedback loops fail,...

02:19Circadian Rhythms and Gene Regulation
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...
