Abstract:
The health of an organism is orchestrated by a multitude of molecular and biochemical networks responsible for ensuring homeostasis within cells and tissues. However, upon aging, a progressive failure in the maintenance of this homeostatic balance occurs in response to a variety of endogenous and environmental stresses, allowing the accumulation of damage, the physiological decline of individual tissues, and susceptibility to diseases. What are the molecular and cellular signaling events that control the aging process and how can this knowledge help design therapeutic strategies to combat age-associated diseases? Here we provide a comprehensive overview of the evolutionarily conserved biological processes that alter the rate of aging and discuss their link to disease prevention and the extension of healthy life span.
Insights
Aging involves the breakdown of cellular balance, leading to damage and disease. Understanding conserved biological processes offers therapeutic strategies to extend healthy life span and prevent age-related illnesses.
Area of Science:
- Molecular biology
- Biochemistry
- Gerontology
Background:
- Organismal health relies on molecular and biochemical networks maintaining homeostasis.
- Aging causes failure in homeostatic balance, leading to damage, tissue decline, and disease susceptibility.
- Endogenous and environmental stresses accelerate aging.
Purpose of the Study:
- To provide a comprehensive overview of evolutionarily conserved biological processes regulating aging.
- To discuss the link between aging processes and disease prevention.
- To explore therapeutic strategies for age-associated diseases based on aging mechanisms.
Main Methods:
