Summary
Modern lifestyles disrupt natural body rhythms, increasing risks for cardiovascular and metabolic disorders. Understanding circadian clock function is key to preventing these diseases of civilization.
Area of Science:
- Chronobiology
- Human Physiology
- Pathology
Background:
- Human lifestyle increasingly diverges from natural environmental and solar cycles.
- Disruption of daily rhythms, including late-night activity and eating, negatively impacts internal temporal organization.
- This misalignment is linked to the rise of 'diseases of civilization'.
Purpose of the Study:
- To review research on the link between circadian regulation disruption and health.
- To focus on the impact of chronodisruption on cardiovascular and metabolic disorders.
- To assess evidence for causality between circadian clock disruption and pathology.
Main Methods:
- Review of selected laboratory studies, including those using spontaneously hypertensive rats.
- Analysis of relevant human studies.
- Assessment of evidence for causality between disrupted circadian rhythms and disease.
Main Results:
- Circadian clock disruption is associated with increased risk of cardiovascular and metabolic disorders.
- Evidence suggests a causal link between chronodisruption and pathology in both animal models and humans.
- Factors like social jetlag and altered chronotype contribute to health issues.
Conclusions:
- Misalignment with daily circadian rhythms significantly impacts health.
- Circadian clock disruption is a contributing factor to cardiovascular and metabolic diseases.
- Further research is warranted to fully elucidate the causal pathways and develop preventative strategies.

Circadian 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...

Psychoneuroimmunology: Cardiovascular Disease
30
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Overview of Carbohydrate Metabolism
981
Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...
