Genetic mutations can extend lifespan by altering endocrine signaling, particularly the insulin pathway. This review explores how these conserved mechanisms in animals relate to aging, diabetes, and longevity.
Area of Science:
- Gerontology
- Molecular Biology
- Endocrinology
Context:
- Aging was historically viewed as a random process.
- Recent research indicates genetic factors influence lifespan.
- Endocrine signaling pathways are implicated in longevity.
Purpose:
- To review long-lived animal models with mutations in the insulin signaling pathway.
- To discuss the link between insulin signaling, diabetes, and longevity.
Summary:
- Single gene expression changes can extend lifespan.
- Mutations affecting longevity are conserved across species (yeast to mice).
- The insulin signaling pathway is a key regulator of longevity.
Impact:
- Provides insights into conserved mechanisms of aging.
- Highlights the connection between metabolic pathways and lifespan.
- Informs research on age-related diseases and interventions.
