PBAE-DOTAP-plasmid DNA lipopolyplexes demonstrate promising transfection efficiency in human vascular endothelial and smooth muscle cells, suggesting potential for nonviral gene therapy in cardiovascular diseases like coronary restenosis.
Hypothesis-generating for nonviral vascular gene therapy; leaves open translation to human restenosis applications.
Safe and effective nonviral gene delivery and transfection in primary human vascular endothelial cells (EC) and smooth muscle cells (SMC) has tremendous potential for cardiovascular diseases such as in the treatment of coronary restenosis. Using a combination of a cationic biodegradable polymer, poly(beta-amino ester) (PBAE), and a cationic phospholipid, 1,2-dioleoyl-3-trimethylammonium propane (DOTAP), we have engineered a lipopolyplex nanovector system that can transfect EC and SMC cells with reasonably high efficiency. For instance, upon addition of 1.0 microg DNA complexed in lipopolyplexes the transfection efficiency in SMC was 20% and in EC was 33%. The results of this study shows that PBAE-DOTAP-plasmid DNA lipopolyplexes are a promising nonviral vector system for gene delivery and transfection in EC and SMC.

Brito et al. (2008) studied Cardiovascular diseases (potential application for coronary restenosis). PBAE-DOTAP-plasmid DNA lipopolyplex nanovector system was evaluated on Transfection efficiency. A lipopolyplex nanovector system combining PBAE and DOTAP achieved transfection efficiencies of 20% in smooth muscle cells and 33% in endothelial cells using 1.0 microg DNA.
