Modeling Lysosomal Storage Diseases in the Zebrafish.

Area of Science:

• Biochemistry
• Genetics
• Developmental Biology

Background:

• Lysosomal storage diseases (LSDs) are a group of 70 inherited metabolic disorders.
• These conditions result from mutations in lysosomal proteins, leading to cellular accumulation of storage materials.
• LSDs often cause multi-organ pathologies, neurodegeneration, and premature death, highlighting the need for better therapies and understanding of disease origins.

Purpose of the Study:

• To review the utility of non-mammalian models for studying LSDs.
• To focus on zebrafish as a vertebrate model organism for LSD research.
• To explore how zebrafish models can advance the understanding of LSD etiology and identify novel therapeutic targets.

Main Methods:

• Review of published literature on zebrafish models of LSDs.
• Analysis of reported phenotypes in zebrafish LSD models.
• Discussion of the advantages and limitations of using zebrafish in LSD research.
• Exploration of technological innovations relevant to zebrafish-based LSD studies.

Main Results:

• Zebrafish exhibit significant genetic and metabolic similarities to mammals, making them suitable for modeling human diseases.
• The optical transparency and high-throughput capabilities of zebrafish offer unique advantages for studying LSDs.
• Various zebrafish LSD models have been developed, exhibiting relevant phenotypes.

Conclusions:

• Zebrafish represent a powerful and versatile model organism for investigating the complex mechanisms of LSDs.
• Further technological advancements can enhance the application of zebrafish models in discovering novel pathways and therapeutic strategies for LSDs.
• Non-mammalian models, particularly zebrafish, are crucial for advancing LSD research beyond traditional approaches.
