Recent development in CRISPR-Cas systems for cardiac disease.

Abstract

The CRISPR-Cas system has emerged as a revolutionary tool in genetic research, enabling highly precise gene editing and significantly advancing the field of cardiovascular science. This chapter provides a comprehensive overview of the latest developments in utilizing CRISPR-Cas technologies to investigate and treat heart diseases. It delves into the application of CRISPR-Cas9 for creating accurate models of complex cardiac conditions, such as hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), and various arrhythmias, which are essential for understanding disease mechanisms and testing potential therapies. The therapeutic potential of gene editing is also explored, with a focus on genes like PCSK9 and ANGPTL3 that play critical roles in lipid metabolism and cardiovascular health, offering promising avenues for new treatments. Furthermore, the expanding applications of CRISPR in heart tissue regeneration are examined, which could revolutionize the repair of damaged heart tissue. Cutting-edge techniques such as base editing and prime editing are discussed, highlighting their potential to further refine genetic interventions. The discussion concludes by addressing the challenges associated with delivering CRISPR components efficiently and safely, while also exploring recent innovations that may overcome these hurdles, providing insights into the future directions of CRISPR technology in cardiovascular medicine.
