Proof-of-concept study for liver-directed miQURE technology in a dyslipidemic mouse model.

ABSTRACT: A gene-silencing platform (miQURE) has been developed and successfully used to deliver therapeutic microRNA (miRNA) to the brain, reducing levels of neurodegenerative disease-causing proteins/RNAs via RNA interference and improving the disease phenotype in animal models. This study evaluates the use of miQURE technology to deliver therapeutic miRNA for liver-specific indications. Angiopoietin-like 3 (ANGPTL3) was selected as the target mRNA because it is produced in the liver and because loss-of-function ANGPTL3 mutations and/or pharmacological inhibition of ANGPTL3 protein lowers lipid levels and reduces cardiovascular risk. Overall, 14 candidate miRNA constructs were tested in vitro, the most potent of which (miAngE) was further evaluated in mice. rAAV5
