Review: African turquoise killifish as a vertebrate aging model
This review assesses the African turquoise killifish as a short-lived vertebrate model for studying aging physiology and testing candidate interventions, while separating established effects from unresolved mechanisms. [1]
Automatic summary · not editorially reviewed
The key findings
The review says the killifish combines a very short life cycle with an intact vertebrate physiological context and an expanding genetic toolkit. [1]
The review focuses on germline-soma interactions, gut microbiota-host crosstalk, nutrient sensing, temperature responsiveness and AMPK-mTOR-linked programs. [1]
The authors distinguish established phenotypic effects from incompletely resolved mechanisms and call for standardization and tissue-resolved causal studies. [1]

Why killifish as an aging model
The review starts from the need for vertebrate models that allow mechanistic work and intervention testing within practical time and cost limits. It says the African turquoise killifish (Nothobranchius furzeri) combines an exceptionally short life cycle with an intact vertebrate physiological context and an expanding genetic toolkit. According to the review, this enables relatively rapid evaluation of candidate aging interventions and analysis across molecular, tissue and organismal levels.

Physiological areas the review covers
The review takes an integrative-physiology perspective. It focuses on germline-soma interactions, crosstalk between gut microbiota and the host, nutrient sensing and metabolic remodeling, temperature responsiveness, and AMPK-mTOR-linked programs. It also examines genome-engineering and reporter approaches that support mechanistic and tissue-resolved study of these processes.

Synthesis and open methodological needs
Building on earlier reviews of killifish biology, disease modeling, regeneration and the hallmarks of aging, the authors synthesize evidence across major intervention domains. They distinguish established phenotypic effects from incompletely resolved mechanisms and discuss functional endpoints, methodological standardization and how to interpret the model's translational relevance. They conclude that future progress requires improved standardization, tissue-resolved causal studies and question-driven cross-species validation where appropriate.

How to interpret this
This is an abstract of a review; the full text was not reviewed. The abstract names physiological areas and intervention domains but reports no specific study results, sample sizes or effect estimates. Statements about the model's usefulness are the authors' assessment, not demonstrated lifespan benefits.
