Description

Stearyl-(homoarginine)8 is a cell-penetrating peptide conjugated to stearic acid that has been used in the generation of liposomes for plasmid DNA or siRNA delivery in vitro.1,2 Liposomes containing stearyl-(homoarginine)8 and in complex with plasmid DNA enter NIH3T3 cells via the endocytosis pathway.1 Liposomes containing a high density, but not a low density, of stearyl-(homoarginine)8 and encapsulating plasmid DNA increase plasmid DNA expression without being degraded by lysosomes in NIH3T3 cells.2 Stearyl-(homoarginine)8-containing liposomes encapsulating siRNA targeting the mRNA encoding GAPDH decrease GAPDH levels in primary human aortic smooth muscle cells.3
