Epigenetic Mechanisms of Aging and Aging-Associated Diseases

Area of Science:

• Molecular Biology
• Gerontology
• Epigenetics

Background:

• Aging is a natural process involving progressive decline in tissue and organ function.
• Molecular alterations in DNA and proteins contribute to aging and age-related diseases.
• Environmental and genetic factors influence these molecular changes.

Purpose of the Study:

• To review epigenetic regulatory mechanisms and their changes associated with aging.
• To highlight the role of epigenetics in age-associated diseases.
• To explore the potential of targeting epigenetic mechanisms for therapeutic interventions.

Main Methods:

• Literature review focusing on epigenetic mechanisms in aging.
• Analysis of molecular changes at DNA and protein levels.
• Examination of the link between epigenetics, aging, and disease.

Main Results:

• Aging is characterized by molecular alterations, including epigenetic changes.
• Epigenetic mechanisms are influenced by genetic and environmental factors.
• These alterations are implicated in various age-related pathologies.

Conclusions:

• Deciphering aging hallmarks, particularly epigenetic factors, can identify therapeutic targets.
• The reversible nature of epigenetic mechanisms offers a potential approach for treating age-related decline.
• Understanding epigenetic changes is crucial for developing therapies against aging and associated diseases.
