Alternative Animal Models of Aging Research

Area of Science:

• Gerontology and evolutionary biology.
• Comparative animal studies of aging.

Background:

• Most aging research uses a few classical models (mouse, fruit fly, roundworm).
• These models offer extensive resources but may introduce interpretation biases.
• Generalizing findings from short-lived models to long-lived species like humans is challenging.

Purpose of the Study:

• To review emerging animal models for aging research.
• To summarize available data and resources for these models.
• To highlight recent insights gained from studying diverse species.

Main Methods:

• Literature review of gerontological research.
• Identification and characterization of novel aging models.
• Synthesis of findings from comparative studies.

Main Results:

• Identified emerging models including killifish, primates, mole-rats, bats, birds, olms, turtles, sharks, bivalves, Hydra, and Planaria.
• Highlighted the unique characteristics and potential of these diverse models.
• Showcased insights into aging mechanisms and longevity from non-classical species.

Conclusions:

• Expanding model systems beyond classical species is crucial for a comprehensive understanding of aging.
• Emerging models provide unique perspectives on longevity and adaptations for healthy aging.
• Further research in these diverse models can overcome limitations of current approaches and reduce generalization biases.
