Mouse models of human disease: An evolutionary perspective.

Area of Science:

• Comparative biology
• Evolutionary medicine
• Biomedical research

Background:

• Mice and humans share genetic and physiological similarities, making mice common model organisms.
• However, distinct evolutionary paths and environmental adaptations have led to significant differences between species.
• These differences impact how mice respond to experimental interventions compared to humans.

Purpose of the Study:

• To evaluate the utility of mice as model organisms in human biology and disease research.
• To highlight the importance of considering evolved differences alongside similarities in experimental design.
• To provide guidance on the appropriate use of mice in biomedical research.

Main Methods:

• Comparative analysis of genetic and physiological traits between mice and humans.
• Review of experimental data demonstrating differential responses to interventions.
• Literature synthesis on conserved biological processes and disease mechanisms.

Main Results:

• Mice are valuable for studying conserved mammalian developmental mechanisms and evolutionary biology.
• Mice exhibit significant differences in their responses to experimental interventions compared to humans.
• The genetic networks underlying disease manifestation likely differ between mice and humans, limiting mouse model reliability for certain human diseases.

Conclusions:

• Mice remain invaluable for specific areas of biological research, particularly conserved processes.
• The reliability of mice as models for human diseases is limited due to species-specific gene-disease networks.
• Biomedical research utilizing mice must carefully account for both shared and divergent evolutionary traits.
