Aging involves accumulating molecular damage due to failing repair pathways. Molecular gerontology research explores genetic and epigenetic factors to enhance maintenance mechanisms, aiming to extend health-span and improve quality of life.

Area of Science:

Gerontology
Molecular Biology
Genetics

Background:

Aging is characterized by progressive molecular damage accumulation.
Inefficient maintenance, repair, and turnover pathways contribute to age-related damage.
Understanding genetic and epigenetic regulation of these pathways is crucial.

Purpose of the Study:

To investigate molecular mechanisms underlying aging.
To explore strategies for modulating the aging process.
To promote healthy aging and extend health-span.

Main Methods:

Studying genetic and epigenetic regulation of survival and maintenance mechanisms.
Investigating various gerontomodulatory approaches, including gene therapy, hormonal supplementation, and nutritional modulation.

Demonstrated potential of various interventions to modulate aging.
Highlighted hormesis as a promising approach for stimulating repair mechanisms.

Conclusions:

Molecular gerontology research provides insights into aging mechanisms.
Multiple strategies can be employed to modulate aging and improve health-span.
A combined approach of molecular, physiological, and psychological interventions can achieve healthy aging.
