The clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein (Cas) system has revolutionized biomedical research and facilitated the development of new therapies based on genome editing1. A major roadblock to achieve the therapeutic potential of the CRISPR/Cas system is the lack of a safe and effectiving in vivo delivery method.
"Here we show that by using an optimized formula of our newly developed
lipid-like nanoparticles (LLNs) [4], we are able to effectively deliver Cas9 mRNA and single-guide RNA (sgRNA) to the liver and achieve in vivo targeting of
HBV DNA and the proprotein convertase subtilisin/kexin type 9 (pcsk9) gene, a therapeutic target for treating hypercholesterolemia [5]. To the best of our
knowledge, this is the first report on non-viral delivery of CRISPR/Cas9 system components (mRNA + sgR-NA) in adult animals. "
