An amphiphilic dendrimer for effective delivery of small interfering RNA and gene silencing in vitro and in vivo.

An amphiphilic dendrimer bearing a hydrophobic alkyl chain and hydrophilic poly(amidoamine) dendrons is able to combine the advantageous features of lipid and dendrimer vectors to deliver a heat shock protein 27 siRNA and produce potent gene silencing and anticancer activity in vitro and in vivo in a prostate cancer model. This dendrimer can be used alternatively for treating various diseases. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
