Candidate molecular targets uncovered in mouse lifespan extension studies

Area of Science:

• Gerontology
• Molecular Biology
• Translational Medicine

Background:

• Numerous interventions extend mouse lifespan, but translation to human clinical applications is limited.
• Challenges include non-standardized controls, sex/strain-specific effects, and a lack of focus on molecular targets.

Purpose of the Study:

• To identify molecular targets of interventions that extend mouse lifespan.
• To assess the translational potential of these interventions and targets for human clinical applications.

Main Methods:

• Analyzed data from DrugAge, GenAge, Mouse Phenome Database, and PubMed for interventions extending mouse lifespan >10%.
• Identified and characterized 10 key molecular targets influenced by these interventions.
• Reviewed clinical trial data and potential indications for each target.

Main Results:

• Identified specific genetic and drug-based interventions associated with significant mouse lifespan extension.
• Characterized 10 molecular targets, highlighting their role in aging and lifespan.
• Assessed the clinical relevance and potential applications of these targets in human aging research.

Conclusions:

• Standardization of mouse lifespan studies, clear control criteria, and geroprotector guidelines are crucial for translational success.
• Focusing on molecular targets enhances understanding of species-specific differences, potential side effects, and optimizes clinical trial design.
• Target identification facilitates the translation of mouse lifespan research into viable human therapies for aging.
