Using Zebrafish Models to Study Epitranscriptomic Regulation of CNS Functions

J Neurochem. 2025 Jan;169(1):e16311. doi: 10.1111/jnc.16311.

Abstract

Epitranscriptomic regulation of cell functions involves multiple post-transcriptional chemical modifications of coding and non-coding RNA that are increasingly recognized in studying human brain disorders. Although rodent models are presently widely used in neuroepitranscriptomic research, the zebrafish (Danio rerio) has emerged as a useful and promising alternative model species. Mounting evidence supports the importance of RNA modifications in zebrafish CNS function, providing additional insights into epitranscriptomic mechanisms underlying a wide range of brain disorders. Here, we discuss recent data on the role of RNA modifications in CNS regulation, with a particular focus on zebrafish models, as well as evaluate current problems, challenges, and future directions of research in this field of molecular neurochemistry.

Keywords: RNA modifications; epitranscriptomic modifications; epitranscriptomics; molecular neurochemistry; zebrafish.
