Development of a Zebrafish S1500+ Sentinel Gene Set for High-Throughput Transcriptomics

Area of Science:

• Transcriptomics
• Bioinformatics
• Zebrafish Model Organism

Background:

• Sentinel gene sets maximize information from targeted transcriptomic platforms.
• A human S1500+ gene set was previously developed using a hybrid data- and knowledge-driven approach.
• Applying this approach to other species requires extensive transcriptomic data, which is limited for zebrafish.

Purpose of the Study:

• To create a sentinel gene set for the zebrafish transcriptome (Zf S1500+).
• To enable whole transcriptome extrapolation and pathway-level inference in zebrafish.
• To support toxicogenomic screening and other research using targeted high-throughput transcriptomics.

Main Methods:

• Utilized human-zebrafish ortholog mapping of the human S1500+ genes.
• Incorporated nominations from experts in the zebrafish scientific community.
• Performed bioinformatics curation and refinement to produce the final Zf S1500+ gene set.

Main Results:

• Successfully developed the Zf S1500+ gene set for zebrafish.
• Demonstrated the utility of the Zf S1500+ gene set for whole transcriptome extrapolation.
• Showcased the gene set's capability for pathway-level inference.

Conclusions:

• The Zf S1500+ gene set is a valuable tool for zebrafish research.
• This gene set enhances the efficiency and scope of targeted transcriptomics in zebrafish.
• It will significantly contribute to toxicogenomic screening and broader biological investigations.
