Epigenetic reprogramming as a key to reverse ageing and increase longevity

Area of Science:

• Epigenetics and Molecular Biology
• Gerontology and Longevity Research
• Biotechnology and Bioengineering

Background:

• Aging is characterized by cellular decline and increased susceptibility to age-related diseases, linked to epigenetic modifications.
• Epigenetic alterations play a crucial role in the aging process and the development of age-related pathologies.

Purpose of the Study:

• To review major epigenetic changes during aging.
• To highlight current epigenetic reprogramming strategies for rejuvenation.
• To discuss the role of epigenetic clocks and future socio-economic/ethical challenges in longevity biotechnology.

Main Methods:

• Review of current scientific literature on epigenetic modifications in aging.
• Analysis of transcription factor-based partial reprogramming techniques.
• Discussion of chemical-based rejuvenation strategies (e.g., small molecules, inhibitors).

Main Results:

• Partial reprogramming can reset the aging clock without erasing cellular identity.
• Epigenetic clocks provide tools for assessing aging and evaluating reprogramming efficacy.
• The longevity biotech industry is rapidly advancing, presenting new opportunities and challenges.

Conclusions:

• Epigenetic reprogramming offers promising avenues for tackling age-related defects and potentially reversing cellular aging.
• Interventions promoting healthy aging are crucial, alongside considerations for socio-economic and ethical implications.
• Further research is inspired to promote healthy aging for all.
