Precision genome editing als potentieel eenmalige therapie voor hyperlipidemie

Atherosclerosis continues to be a primary contributor to global cardiovascular mortality, influenced by intricate lipid and inflammatory mechanisms. Despite the efficacy of conventional pharmacotherapies, ongoing issues of patient non-adherence and residual risk have prompted the exploration of more enduring therapeutic alternatives. This review examines the significant transition in cardiovascular research from conventional, wide knockout models to the utilization of advanced precision genome editing methods, particularly emphasizing CRISPR-Cas9, base editing, and prime editing. These sophisticated molecular tools allow for the accurate insertion and rectification of single-nucleotide variants without causing double-strand breaks, marking a significant shift from rudimentary gene disruption to precise variant engineering. By specifically targeting essential lipid-regulating genes like proprotein convertase subtilisin/kexin type 9 (PCSK9) and angiopoietin-like 3 (ANGPTL3), precision editing presents an exceptional opportunity for lasting, one-shot lipid-lowering treatments. Additionally, we examine the advancement of preclinical modeling, emphasizing humanized models that precisely represent population genetics. This review highlights the essential obstacles to clinical translation, focusing on the optimization of delivery systems such as adeno-associated viruses (AAVs) and lipid nanoparticles (LNPs), as well as the thorough assessment of off-target effects and ethical implications.
