Nanoparticle-Mediated Target Delivery of TRAIL as Gene Therapy for Glioblastoma.

ABSTRACT: Human tumor necrosis factor α-related apoptosis-inducing ligand (TRAIL) is an attractive cancer therapeutic because of its ability to induce apoptosis in tumor cells while having a negligible effect on normal cells. However, the short serum half-life of TRAIL and lack of efficient in vivo administration approaches have largely hindered its clinical use. Using nanoparticles (NPs) as carriers in gene therapy is considered as an alternative approach to increase TRAIL delivery to tumors as transfected cells would be induced to secrete TRAIL into the tumor microenvironment. To enable effective delivery of plasmid DNA encoding TRAIL into glioblastoma (GBM), we developed a targeted iron oxide NP coated with chitosan-polyethylene glycol-polyethyleneimine copolymer and chlorotoxin (CTX) and evaluat
