Scientific Advances: CRISPR reduces low-density lipoprotein (LDL) cholesterol in pre-clinical study

March 9, 2021.

While developing a new lipid nanoparticle (LNP)-based in vivo delivery platform for CRISPR/Cas9 gene editing in the liver, Qiu et al. focused on the disruption of the Angiopoietin-like 3 (Angptl3) gene. This gene is a potential target for therapeutic interventions against human lipoprotein metabolism disorders. Using a pre-clinical mouse model, the authors were able to demonstrate specific and efficient Angptl3 disruption using their LNP delivery system, resulting in a profound reduction of low-density lipoprotein cholesterol, and triglyceride serum levels.
