Sep 25, 2009 · In contrast to delivery vehicles composed of cationic lipids or polycations, the PKCNs are ‘hard’ materials composed of water-insoluble polymers and have a strong thermodynamic driving force to maintain their integrity in vivo. The PKCNs are acid sensitive, and hydrolyze after phagocytosis in the acidic environment of the phagosome, allowing them to rapidly release siRNA after cell internalization …Author: Sungmun Lee, Stephen C.

In this Account, we highlight examples of polycation–PAO conjugates, liposome–PAO formulations, and PAO micelles for nucleic acid delivery. Among the various polymer design considerations, which include molecular weight of polymer, molecular weight of blocks, and length of blocks, the overall hydrophobic–lipophilic balance (HLB) is a ...Author: Swati Mishra, Lavanya Y Peddada, David I Devore, Charles M Roth

In contrast to highly efficient viral delivery vectors, non-viral counterparts bear less immunostimulatory, mutagenetic, and oncogenic complications; some can approach transfection efficiencies comparable to viruses. 17 Therapeutic nucleic acids of interest for nanomedicine can be DNA in plasmids (pDNA), antisense oligonucleotides (AONs), ribozymes, DNAzymes, and more recently, siRNA and shRNA. …

Feb 01, 2014 · PEI is a cationic polymer widely used for nucleic acid delivery. 21 It is particularly promising vector with relatively high level of transfection in a number of target organs. The high charge density of PEI is thought to be a key factor that contributes to its high transfection efficiency.Author: Azam Bolhassani, Shabnam Javanzad, Tayebeh Saleh, Mehrdad Hashemi, Mohammad Reza Aghasadeghi, Seyed ...

Polymers can also be used to encapsulate nucleic acids for in vivo delivery. Generally, polymers can be divided into two groups: natural or synthetic. Biologically occurring molecules such as peptides, oligosaccharides, and even nucleic acids themselves are natural polymers.Author: Emily B. Harrison, Salma H. Azam, Chad V. Pecot

Intracellular nucleic acid delivery has the potential to treat many genetically-based diseases, however, gene delivery safety and efficacy remains a challenging obstacle. One promising approach is the use of polymers to form polymeric nanoparticles with nucleic acids that have led to exciting advances in non-viral gene delivery.Author: Corey J. Bishop, Kristen L. Kozielski, Jordan J. Green, Jordan J. Green
