Translatability of life-extending pharmacological treatments between different species

Area of Science:

• Gerontology and Longevity Research
• Comparative Biology
• Translational Medicine

Background:

• Significant progress in anti-aging research has identified interventions extending lifespan in diverse organisms.
• Numerous treatments demonstrate efficacy in animal models, from invertebrates to mammals.

Purpose of the Study:

• To review the current landscape of anti-aging interventions and their observed effects on lifespan.
• To analyze the challenges and barriers in translating anti-aging discoveries from animal models to human applications.
• To identify key factors influencing the efficacy of longevity mechanisms across species.

Main Methods:

• Comprehensive literature review of anti-aging studies across various organisms.
• Comparative analysis of lifespan extension data and treatment efficacy.
• Identification and synthesis of challenges in human translation.

Main Results:

• Lifespan extension has been achieved in multiple animal models using various anti-aging strategies.
• Significant challenges exist in translating these findings to humans due to biological complexity and species differences.
• Metabolic and genetic variations, alongside pathway redundancy, impede direct application of interventions.

Conclusions:

• Translating anti-aging treatments to humans is complex, requiring deeper understanding of species-specific biology.
• Overcoming barriers in translatability is crucial for developing effective human anti-aging therapies.
• Advancing research in this area is essential for potentially extending human healthspan.
