摘要

Aim: To develop a peptide/phospholipid hybrid system for gastrin-releasing peptide receptor (GRPR)-targeted delivery of pDNA or siRNA. Materials & methods: A multifunctional GRPR-targeted peptide R-9-K(GALA)-BBN(6-14) was combined with a phospholipid oligonucleotide delivery system (1:1 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine and 1,2-dioleoyl-3-trimethylammonium-propane) and evaluated for pDNA and siRNA delivery in terms of complex size, toxicity, receptor-targeted delivery and gene expression or knockdown efficiency. Results: By combining peptide and phospholipid delivery systems, synergistic improvements in gene expression and knockdown were observed when compared with either system alone. The optimized formulation demonstrated high levels of EGFP expression and EGFP knockdown, GRPR-targeted delivery, enhanced endosomal release and minimal toxicity. Conclusion: The peptide/phospholipid hybrid system provides efficient GRPR-targeted DNA/siRNA delivery.
