Zebrafish models of cardiovascular disease

Area of Science:

• Biomedical research
• Cardiovascular science
• Genetics

Background:

• Cardiovascular disease (CVD) is a leading global cause of death.
• Key risk factors include hypertension, high cholesterol, diabetes, smoking, and obesity.
• Research actively investigates CVD causes, prevention, and treatments, with numerous studies published weekly.

Purpose of the Study:

• To explore recent advances in identifying genetic causes and molecular mechanisms of CVDs.
• To investigate novel therapeutic drugs for cardiovascular diseases.
• To highlight the utility of zebrafish (Danio rerio) as a model organism in CVD research.

Main Methods:

• Utilizing zebrafish (Danio rerio) as a high-throughput, low-cost model organism.
• Employing forward and reverse genetics approaches.
• Conducting noninvasive in vivo imaging for cardiovascular phenotype analysis.
• Performing functional verification of candidate genes identified through genome-wide association studies.

Main Results:

• Zebrafish models facilitate understanding of CVD pathogenesis and testing of new therapies.
• Genome-wide association studies and functional verification have identified several genes involved in CVD pathophysiology.
• Zebrafish exhibit lifelong cardiac regeneration capabilities, offering insights into human cardiac repair.

Conclusions:

• Zebrafish are a valuable tool for high-throughput genetic and drug screening in cardiovascular research.
• This model aids in elucidating the genetic underpinnings and molecular pathways of cardiovascular diseases.
• Zebrafish research provides novel perspectives on cardiac regeneration and potential therapeutic strategies for CVDs.
