Zebrafish as a tool to study schizophrenia-associated copy number variants

Area of Science:

• Neurodevelopmental disorders
• Behavioral genetics
• Molecular psychiatry

Background:

• Schizophrenia is a debilitating neurodevelopmental disorder with significant societal impact.
• Genetic factors, particularly copy number variants (CNVs), are major contributors to schizophrenia risk.
• Existing rodent models of CNVs have limitations in elucidating underlying molecular mechanisms.

Purpose of the Study:

• To review the utility of zebrafish as a model organism for studying schizophrenia.
• To highlight how zebrafish can investigate gene contributions to CNV-mediated brain dysfunction.
• To identify potential therapeutic targets for schizophrenia.

Main Methods:

• Review of existing literature on CNVs and schizophrenia.
• Assessment of zebrafish genetic and neurobiological conservation with humans.
• Evaluation of zebrafish high-throughput screening capabilities.

Main Results:

• Zebrafish possess conserved genetics and neural substrates relevant to schizophrenia.
• The zebrafish offers a robust toolkit for genetic and pharmacologic screens.
• Zebrafish enable high-content analysis of CNV effects on brain function.

Conclusions:

• Zebrafish are well-suited to unraveling molecular mechanisms of schizophrenia-associated neurodevelopmental deficits.
• This model system can facilitate the discovery of novel therapeutic targets for schizophrenia.
• Investigating CNVs in zebrafish promises deeper insights into schizophrenia pathogenesis.
