BackgroundNanocarrier-based systems have cultivated significant improvements in prostate cancer therapy. However, the efforts are still limited in clinical applicability, and more research is required for the development of effective strategies. Here, we describe a novel nanoliposomal system for targeted apoptotic gene delivery to prostate cancer.MethodsPoly (2-ethyl-2-oxazoline) (PEtOx) dioleoyl phosphatidylethanolamine (DOPE) nanoliposomes were conjugated with the prostate-specific membrane antigen (PSMA)-targeting peptide GRFLTGGTGRLLRIS (P563) and loaded with BikDDA, a mutant form of the proapoptotik Bik. We selected 22Rv1 cells with moderate upregulation of PSMA to test the in vitro uptake, cell death, and in vivo anti-cancer activity of our formulation, P563-PEtOx-DOPE-BikDDA.ResultsBikDDA was upregulated in 22Rv1 cells, inducing cell death, and CD-1 nude mice xenografts administered with the formulation showed significant tumor regression.ConclusionWe suggest that P563-PEtOx-DOPE-BikDDA nanoliposomes can serve as prominent gene carriers against prostate cancer.
