Application of Zebrafish in Mitochondrial Dysfunction

Abstract

This chapter provides an overview of the zebrafish (Danio rerio) as a model organism for studies of mitochondrial dysfunction. Zebrafish possess a genetic similarity with humans and have conserved mitochondrial genomes, rendering them a valuable research tool for examining the intricate mechanisms that govern mitochondrial processes at diverse developmental stages. The chapter explores several methods for evaluating mitochondrial health and function. Examples include in vitro cell culture and in vivo analysis in embryos, larvae, and adults. The chapter discusses the use of zebrafish models in toxicological research to investigate mitochondrial reactions to environmental stressors and xenobiotics. The importance of implementing standardized protocols, validating marker, integrating different omics data, and using in vivo and in vitro approaches to advance mitochondrial research will be highlighted. In summary, zebrafish are suitable for analyzing both mitochondrial function and dysfunction, as well as their impact on human health.
