Reducible cationic lipids for gene transfer.
One of the main challenges of gene therapy remains the increase of gene delivery into eukaryotic cells. We tested whether intracellular DNA release, an essential step for gene transfer, could be facilitated by using reducible cationic DNA-delivery vectors. For this purpose, plasmid DNA was complexed with cationic lipids bearing a disulphide bond. This reduction-sensitive linker is expected to b...
متن کاملCationic lipids and polymers for gene delivery
Gene therapy, aiming to eradicate causes rather than symptoms of diseases, is believed to be the therapy of the future. A new promising area for the application of gene therapy is the emerging field of regenerative medicine, where gene delivery can be used to enhance or modify cell functions in an organ/tissue or in engineered substitutes. The aim of gene therapy is to achieve the expression of...
متن کاملCationic polymer and lipids augment adenovirus-mediated gene transfer to cerebral arteries in vivo.
Adenovirus-mediated gene transfer to blood vessels is relatively inefficient because binding of adenovirus to vessels is limited. The authors have reported that incorporation of cationic polymer and lipids with adenovirus augments gene transfer to blood vessels ex vivo. In this study, the authors determined whether complexes of adenovirus and cations improve efficiency of gene transfer in vivo....
متن کاملA series of cationic sterol lipids with gene transfer and bactericidal activity.
A family of cationic lipids was synthesized via direct amide coupling of spermine to the C-24 position of cholic acid analogs. Four monosubstituted spermines and a bis-substituted spermine were evaluated as plasmid transfection reagents, as bacteriostatic agents, and as bactericidal agents. The incorporation of a double bond in the sterol moiety enhanced transfection efficiency significantly an...
متن کاملCationic polymer and lipids enhance adenovirus-mediated gene transfer to rabbit carotid artery.
BACKGROUND AND PURPOSE Improvement of efficiency of gene transfer to endothelium could be useful for several applications. We tested the hypothesis that cationic nonviral molecules augment adenovirus-mediated gene transfer to blood vessels, perhaps by alteration of the surface charge of adenovirus and facilitation of binding to endothelium. METHODS Carotid arteries from rabbits were incubated...
