[Molecular gerontology: towards healthy aging]

Area of Science:

• Biogerontology
• Genetics
• Molecular Biology

Context:

• Aging research has evolved from social sciences to a dynamic biological field.
• Gene mutations are shown to significantly modulate the aging process.
• Discoveries in model organisms inform human aging studies.

Purpose:

• To explore the biological basis of aging.
• To identify genes and pathways influencing lifespan.
• To investigate the genetic factors contributing to human longevity.

Summary:

• Single gene mutations can alter aging, highlighting the plasticity of involved pathways.
• Lifespan extension interventions in yeast, worms, and flies are evolutionarily conserved.
• Nutrient-sensing pathways and dietary restriction are key to health and longevity.
• Genome-wide studies of centenarians aim to identify human aging-related genes.

Impact:

• Establishes the evolutionary relevance of invertebrate aging research to humans.
• Identifies nutrient-sensing pathways as conserved longevity mechanisms.
• Provides a foundation for understanding the genetic basis of healthy human aging.
