    A hyperlipidemia zebrafish model was established using a 4% cholesterol diet for 20 days. Berberine effectively lowered lipid levels and liver fat, validating this model for lipid-lowering drug screening.

    Area of Science:

    • Pharmacology
    • Zebrafish models
    • Lipid metabolism

    Context:

    • Hyperlipidemia is a significant risk factor for cardiovascular diseases.
    • Developing efficient and reliable drug screening models is crucial for identifying novel lipid-lowering therapies.
    • Zebrafish offer a cost-effective and rapid in vivo system for pharmacological studies.

    Purpose:

    • To establish a practical hyperlipidemia model in zebrafish for drug screening.
    • To evaluate the lipid-lowering effects of berberine (BBR) in this established model.
    • To assess the impact of BBR on key lipid metabolism markers and gene expression.

    Summary:

    • A hyperlipidemia zebrafish model was successfully created by feeding with 4% cholesterol for 20 days, showing elevated serum total cholesterol.

  • Berberine treatment significantly reduced serum total cholesterol, triglyceride, and LDL-c levels.
  • Berberine also decreased hepatic HMGCR mRNA expression and liver fat content, while increasing LDLR and CYP7A1a mRNA expression.

    • Impact:

    • This study validates a robust zebrafish model for hyperlipidemia drug discovery.
    • The findings demonstrate berberine's potential as a therapeutic agent for hyperlipidemia.
    • This model provides a foundation for high-throughput screening of novel lipid-lowering compounds.
