Colorectal cancer has been one of the most common cancers in the worldwide. Poor patient compliance and serious side effects often associated with conventional therapy (e.g. surgery, radiation, and chemotherapy). Gene therapy may be an alternative strategy. Herein, we developed a dual-targeting nanoparticle with excellent gene transfection efficiency for gene therapy of peritoneal metastasis of colorectal cancer. This nanoparticle can facilitate efficient cellular uptake and promote penetration into nucleus. Meanwhile, this nanoparticle mediated efficient gene transfection in medium with or without serum, which significantly surpassed that of commercial transfection reagents, Lipofectamine 2000 and Lipofectamine 3000. After systemic administration, this nanoparticle loaded with hTRAIL plasmid significantly inhibited peritoneal metastasis of colorectal cancer in vivo. In conclusion, this dual-targeting nanoparticle has great potential to be a gene delivery vector for colorectal cancer therapy.
