Abstract:

We described a novel approach for survivin siRNA cellular delivery via a cationic liposome incorporating fatty acid-modified polyethylenimine. A linoleic acid derivative of branched polyethylenimine(PEI, Mw=25 kDa), PEI-LA, was synthesized and incorporated into the liposome. The properties of the liposome, cytotoxicity, cellular uptake of cancer cells for survivin siRNA, survivin protein downregulation levels were investigated. PEI-modified liposome showed a lower cytotoxicity and delivered survivin siRNA into HeLa cells and A549 cells efficiently compared with PEI-25kDa.
