Abstract:
Insight on the underlying mechanisms of aging will advance our ability to extend healthspan, treat age-related pathology and improve quality of life. Multiple genetic and pharmacological manipulations extend longevity in different species, yet monotherapy may be relatively inefficient, and we have limited data on the effect of combined interventions. Here we summarize interactions between age-related pathways and discuss strategies to simultaneously retard these in different organisms. In some cases, combined manipulations additively increase their impact on common hallmarks of aging and lifespan, suggesting they quantitatively participate within the same pathway. In other cases, interactions affect different hallmarks, suggesting their joint manipulation may independently maximize their effects on lifespan and healthy aging. While most interaction studies have been conducted with invertebrates and show varying levels of translatability, the conservation of pro-longevity pathways offers an opportunity to identify 'druggable' targets relevant to multiple human age-associated pathologies.
Insights
Combining interventions targeting aging pathways can extend lifespan and healthspan more effectively than single treatments. These combined approaches may offer new therapeutic strategies for age-related diseases.
Area of Science:
- Gerontology and aging research
- Molecular biology of aging
- Genetics of longevity
Background:
- Understanding aging mechanisms is crucial for extending healthspan and treating age-related diseases.
- Single interventions (monotherapy) show limited efficiency in extending longevity.
- Limited data exists on the combined effects of aging interventions.
Purpose of the Study:
- To summarize interactions between age-related pathways.
- To discuss strategies for simultaneously targeting multiple aging pathways.
- To explore the potential of combined interventions for healthspan and lifespan extension.
Main Methods:
- Review and synthesis of existing literature on aging pathways and interventions.
- Analysis of interactions between different genetic and pharmacological manipulations.
- Examination of effects on hallmarks of aging and lifespan across different organisms.
Main Results:
- Combined manipulations can additively impact common aging hallmarks and lifespan, suggesting shared pathway participation.
- Interactions between interventions targeting different hallmarks can independently maximize effects on lifespan and healthy aging.
- Most interaction studies are in invertebrates, with varying translatability to humans.
Conclusions:
- Simultaneous targeting of multiple aging pathways offers a promising strategy for enhancing longevity and healthspan.
- Conserved pro-longevity pathways present opportunities for identifying druggable targets for human age-associated pathologies.
- Combined interventions may provide a more efficient approach to combatting aging and its related diseases.
