[Key Molecular Mechanisms of Aging, Biomarkers, and Potential Interventions]

Area of Science:

• Gerontology and molecular biology.
• Integrative biology of aging.

Background:

• Aging is characterized by molecular lesions and cellular stress responses.
• Homeostatic mechanisms deteriorate with age, leading to increased disease risk.
• A critical threshold of errors triggers a systemic health-to-disease transition.

Purpose of the Study:

• To review the multi-level mechanisms of aging.
• To discuss quantitative assessment methods for aging (biomarkers).
• To explore interventions for slowing aging and reducing age-related disease risk.

Main Methods:

• Review of scientific literature on aging mechanisms.
• Analysis of age-dependent molecular and cellular processes.
• Examination of systemic changes and disease transitions.

Main Results:

• Aging involves progressive deterioration of compensatory mechanisms.
• Biomarkers of aging are crucial for quantitative assessment.
• Interventions targeting aging pathways show promise for healthspan extension.

Conclusions:

• Understanding aging mechanisms is key to combating age-related diseases.
• Biomarkers and targeted interventions offer new therapeutic avenues.
• Slowing the aging process can significantly improve public health.
