Mass spectrometry for proteomics-based investigation using the zebrafish vertebrate model system

Area of Science:

• * Utilizes the zebrafish (Danio rerio) model organism for studying human disease genetics and pathologies.
• * Leverages conserved vertebrate organ systems and disease-causing genes for translational research.

Background:

• * Zebrafish are widely used for genetic studies due to ease of manipulation and genetic conservation.
• * While genetic techniques are advanced, proteomic applications in zebrafish research remain relatively under-explored.
• * This review focuses on existing proteomic studies and presents novel comparative proteomic data.

Purpose of the Study:

• * To review the current applications of proteomics in zebrafish disease modeling.
• * To present initial findings from a proteomic comparison between ascl1a mutant and wild-type zebrafish intestine.
• * To highlight the potential of proteomics in advancing zebrafish-based research.

Main Methods:

• * Literature review of published proteomic studies in zebrafish.
• * Proteomic analysis comparing the intestinal proteome of ascl1a knockout (ascl1a-/-) zebrafish and wild-type (WT) controls.
• * Mass spectrometry-based proteomics to identify and quantify protein expression differences.

Main Results:

• * Identified significant differences in protein expression between ascl1a-/- and WT zebrafish intestine.
• * The proteomic data provides insights into the molecular mechanisms underlying intestinal development and disease in the absence of ascl1a.
• * Specific protein pathways affected by the ascl1a mutation were highlighted.

Conclusions:

• * Proteomics offers a powerful approach to complement genetic studies in zebrafish disease models.
• * The comparative proteomic analysis reveals key molecular changes in the ascl1a mutant intestine.
• * Further proteomic investigations in zebrafish will enhance understanding of human disease genetics and pathology.
