Developing zebrafish disease models for in vivo small molecule screens

Area of Science:

• Comparative Biology
• Genetics and Genomics
• Pharmacology

Background:

• The zebrafish (Danio rerio) serves as a powerful vertebrate model organism.
• It facilitates in vivo studies at a scale typically achievable only in vitro.
• This characteristic makes it ideal for high-throughput screening of small molecules.

Purpose of the Study:

• To review strategies for developing zebrafish disease models.
• To discuss considerations for using these models in small molecule screens.
• To highlight the utility of zebrafish in drug discovery and disease research.

Main Methods:

• Review of established zebrafish disease modeling techniques.
• Analysis of approaches including mutagenesis, transgenesis, and pharmacological induction.
• Consideration of infectious and cancerous agent exposure models.

Main Results:

• Multiple validated methods exist for creating diverse zebrafish disease models.
• Zebrafish models are amenable to in vivo screening of thousands of compounds.
• These models effectively recapitulate human disease phenotypes for study.

Conclusions:

• Zebrafish offer a scalable platform for in vivo drug screening.
• Careful model development is crucial for successful small molecule screens.
• Zebrafish are a valuable tool for advancing human disease research and therapeutic development.
