Zebrafish (Danio rerio) offers a complex vertebrate model for genetic research. Its unique genomic tools, like morpholino-based gene inhibition, accelerate in vivo gene function studies and drug discovery.

Area of Science:

  • Genomics
  • Developmental Biology
  • Pharmacology

Background:

  • The zebrafish (Danio rerio) is increasingly utilized as a vertebrate model organism in genomic research.
  • It possesses biological and genomic complexity comparable to higher vertebrates, alongside advantageous technical properties.
  • Classical models lack the experimental flexibility offered by zebrafish for advanced genetic approaches.

Purpose of the Study:

  • To highlight the utility of zebrafish as a model system for functional genomics and drug discovery.
  • To introduce novel genomic tools, such as morpholino-based gene inhibition, for screening gene function.
  • To emphasize the potential of zebrafish in identifying drug targets and developing novel pharmaceuticals.

Main Methods:

  • Utilizing forward and reverse genetics for functional access to the zebrafish genome.
