Aging: Somatic Mutations, Epigenetic Drift and Gene Dosage Imbalance

Area of Science:

• Gerontology
• Genomics
• Molecular Biology

Background:

• Aging is characterized by declining metabolic function and increased disease incidence.
• Genomic and epigenomic alterations significantly influence aging processes and age-related phenotypes.
• The precise mechanisms linking genomic changes to metabolic dysregulation in aging remain unclear.

Purpose of the Study:

• To present a novel model connecting genome-wide alterations to age-related phenotypic consequences.
• To elucidate the role of macromolecular complexes and cellular networks in mediating these changes.
• To enhance understanding of the dynamic genome-phenome relationship during aging.

Main Methods:

• Development of a conceptual model linking genomic changes to phenotypic outcomes.
• Analysis of how alterations in macromolecular complexes and cellular networks contribute to aging.
• Integration of genomic, epigenomic, and phenotypic data to map age-related changes.

Main Results:

• The proposed model links genome-wide changes to age-related metabolic decline and disease.
• Alterations in macromolecular complexes and cellular networks are identified as key mediators.
• The study highlights the dynamic nature of the genome-phenome map with advancing age.

Conclusions:

• The model provides a framework for understanding aging at the genomic and phenotypic levels.
• This approach offers potential for developing targeted therapies for late-onset disorders.
• Insights gained may aid in decelerating the aging process and managing age-related diseases.
