Efficient non-viral vectors for gene delivery based on chitosan polymer is dependent on a variety of factors, e.g. loading and lelease capacity, stability in biological system and complex size. This system may have low loading, release and stability capacity. Biodegradable and biocompatible nanoparticles formulated using a chitosan polymer has the potential for sustained and controlled gene delivery. Our hypothesis is that nanoparticles-mediated wild-type p53 gene delivery would result in sustained gene expression, and hence better efficacy with a therapeutic gene. In this study, we have determined the pharmaceutical and biological characterization of Chitosan nanoparticles containing wild-type p53. Nanoparticles containing plasmid were formulated using a microemulsion reverse micellar and ionic gelation techniques. In conclusion, chitosan nanoparticles- p53 complex gene delivery results in sustained and better antiproliferative activity, which could be therapeutically beneficial in cancer treatment.
