A CRISPR Path to Engineering New Genetic Mouse Models for Cardiovascular Research

Area of Science:

• Genetics
• Molecular Biology
• Cardiovascular Research

Background:

• Traditional mouse genome modification techniques were complex and labor-intensive.
• The clustered regularly interspaced short palindromic repeats (CRISPR) technology offers a simpler, more accessible approach.
• CRISPR has revolutionized the creation of genetically modified organisms, including mouse models.

Purpose of the Study:

• To review the history and core components of CRISPR technology.
• To provide practical guidance for CRISPR genome editing in mice.
• To highlight applications of CRISPR in cardiovascular research and discuss associated challenges.

Main Methods:

• Review of CRISPR history from prokaryotes to animal genome modification.
• Explanation of CRISPR-Cas9 system components and editing strategies (2- and 3-component).
• Summary of applications including frameshift mutations, deletions, substitutions, and tag integration.

Main Results:

• CRISPR enables efficient and versatile genome editing in mice.
• Facile generation of various genetic modifications for research purposes.
• Discussion of genotyping, mosaicism, and off-target effects.

Conclusions:

• CRISPR technology has democratized genome editing for mouse model generation.
• It accelerates research in areas like cardiovascular disease.
• Ethical considerations and clinical applications are important as the technology advances.
