Preparation and evaluation of a non-viral gene vector for SiRNA: Multifunctional envelope-type nano device.
Authors: Zhang Y, Wei H, Xu L, Yan G, Ma C, Yu M, Wei C, Sun Y Abstract We prepared and evaluated a multifunctional envelope-type nano device (MEND) as a liver-targeting and long-circulation carrier for SiRNA. The polymer GA-PEG-Pp-DOPE was synthesized by modifying polyethylene glycol (PEG) with glycyrrhetinic acid (GA), peptide (Pp), and dioleoyl phosphoethanolamine (DOPE). The Pp is a substrate of matrix metalloproteinase 2. MEND was prepared with GA-PEG-Pp-DOPE and cationic phospholipids by the filming-rehydration method, and the orthogonal test was applied to optimize the prescription. The results of the biolog...
