Abstract

Aim: The design of novel F3-targeted liposomes with adequate features for systemic administration, to enable efficient intracellular delivery of siRNA toward both cancer and endothelial cells from angiogenic blood vessels. Materials & methods: Cellular association studies were performed by flow cytometry. Gene silencing was evaluated with eGFP-overexpressing cells, by flow cytometry and real-time reverse-transcription PCR. Safety and immunogenicity was assessed in CD1 mice. Results: A strong improvement on siRNA internalization by the target cells was achieved, which was correlated with effective downregulation of eGFP. In addition, the F3-targeted liposomes were nonimmunogenic, even in a multiadministration schedule. Conclusion: Overall, the developed F3-targeted nanocarrier constitutes a valuable tool for the specific and safe systemic delivery of siRNA to solid tumors.
