Proteoglycans Mediate Cationic Liposome-DNA Complex-based Gene Delivery in Vitro and in Vivo

Cationic liposome-mediated gene delivery in vivo.

Several improvements have been made in liposomal delivery, thus making this technology potentially useful for treatment of certain diseases in the clinic. Success in non-viral delivery is complicated and requires optimization of several components. These components include nucleic acid purification, plasmid design, formulation of the delivery vehicle, administration route and schedule, dosing, ...

preparation and in vitro transfection of modified cationic liposome-linear polyethyleneimine-dna nanocomplexes for gene delivery

Cationic liposome-DNA complexes as gene delivery vectors: Development and behaviour towards bone-like cells.

Modulation of the biological pathways responsible for fracture repair and osteogenisis may accelerate regeneration. Gene therapy is an alternative method for the release of osteogenisis-stimulating proteins into tissues. The development of vectors for gene release is still a problem in terms of ethics and techniques. In this work we evaluated whether cationic liposomes constitute a valuable str...

Studies on neutral, cationic and biotinylated cationic microbubbles in enhancing ultrasound-mediated gene delivery in vitro and in vivo.

Ultrasound-mediated gene transfer is emerging as a practical means of facilitating targeted gene expression and is significantly enhanced in the presence of exogenously added microbubbles. This study explores the influence of microbubble surface modifications on their interaction with plasmid DNA and target cells, and the functional consequences of those interactions in terms of ultrasound-medi...

Competition of charge-mediated and specific binding by peptide-tagged cationic liposome-DNA nanoparticles in vitro and in vivo.

Cationic liposome-nucleic acid (CL-NA) complexes, which form spontaneously, are a highly modular gene delivery system. These complexes can be sterically stabilized via PEGylation [PEG: poly (ethylene glycol)] into nanoparticles (NPs) and targeted to specific tissues and cell types via the conjugation of an affinity ligand. However, there are currently no guidelines on how to effectively navigat...
