This study not only provides a clinically-applicable lipid nanocarrier for delivering CRISPR/Cas system (even other bioactive molecules), but also constitutes a potential cancer treatment regimen base on DNA editing of oncogenes. Copper based nanoparticles (NPs) are used extensively in industrial and commercial products as sensors, catalysts, surfactants, antimicrobials, and for other purposes. In addition, it also achieved excellent tumor growth suppression compared to other nucleic acid modalities such as siRNA, without inducing adverse effects to the main organs including the liver and kidneys.
iLP181/psgPLK1 significantly accumulated in the tumor for more than 5 days after a single intravenous injection. The nanoformulation effectively triggered editing of PLK1 gene with more than 30% efficiency in HepG2-Luc cells. The iLP181/psgPLK1 nanoformulation showed uniformity in size, regular nanostructure and nearly neutral zeta potential at pH 7.4. The iLP181 effectively encapsulate psgPLK1, the best-performing plasmid expressing for both Cas9 protein and sgRNA targeting Polo-like kinase 1 (PLK1). Here, we report an ionizable lipid nanoparticle (iLP181, p Ka = 6.43) based on iLY1809 lipid enabling robust gene editing in vitro and in vivo. The zeta potential ( ) analysis was also per-using a Laser Doppler Anemometry (LDA) (Zetasizer 3000 Malvern Instruments, UK). However, the lack of safe and efficient delivery carrier is one of the crucial factors restricting its clinical transformation. light scattering (Zetasizer 3000 HS, Malvern UK) analysis of NS-QUE was performed at 90 in to determine themean hydrodynamic diameter and index of the particle population in three different batches. CRISPR/Cas9-based gene editing has emerged as a powerful biotechnological tool, that relies on Cas9 protein and single guided RNA (sgRNA) to edit target DNA.
