ABSTRACT: Background
Gene editing has emerged as an exciting therapeutic development platform for numerous genetic and nongenetic diseases. Targeting lipid-modulating genes such as angiopoietin-related protein 3 (ANGPTL3) with gene editing offers hope for a permanent solution to lower cardiovascular disease risks associated with hypercholesterolemia.Results
In this study, we developed a hepatocyte-specific base editing therapeutic approach delivered by dual adeno-associated virus (AAV) to enable hepatocyte-specific targeting of Angptl3 to lower blood lipid levels. Systemic AAV9-mediated delivery of AncBE4max, a cytosine base editor (CBE), targeting mouse Angptl3 resulted in the installation of a premature stop codon in Angptl3 with an average efficiency of 63.3 ± 2.3% in the bulk liver tissue. A near-complete knockout of the ANGPTL3 protein in the circulation were observed within 2-4 weeks following AAV administration. Furthermore, the serum levels of triglyceride (TG) and total cholesterol (TC) were decreased by approximately 58% and 61%, respectively, at 4 weeks after treatment.Conclusions
These results highlight the promise of liver-targeted Angptl3 base editing for blood lipid control.
