Cover Story: Lipocalin 2 (Lcn2) overexpression can lead to cancer progression by enhancing tumor angiogenesis. In this study, we engineered a PEGylated liposomal system encapsulating Lcn2 small interfering RNA (Lcn2 siRNA). The PEGylated liposomes were decorated with octreotide (OCT) peptide for targeting breast cancer cells. Optimized OCT-targeted Lcn2 siRNA liposomes (OCT-Lcn2-Lipo) had a mean size of 152 nm and 69.5% encapsulation efficiency. OCT-Lcn2-lipo could achieve 55−60% silencing of Lcn2 mRNA in MCF-7 and MDA-MB-231 cells. In addition, OCT-Lcn2-Lipo demonstrated in vitro anti-angiogenic effects by reducing VEGF-A levels in treated cells. OCT-Lcn2-lipo also reduced the endothelial cell (HUVEC) migration levels. This approach may be useful in inhibiting angiogenesis and metastasis in breast cancer. View this paper
