Abstract

Abstract Short interfering RNA (siRNA) has emerged as a promising molecular therapeutic tool for targeted cancer treatment. However, systemically administered siRNA has demonstrated only limited success, due to limited delivery to cancer cells. Therefore, the lack of a robust and versatile siRNA delivery system is a critical issue in translating this therapeutic tool for cancer treatment. Recent developments in DNA nanotechnology have made programmable DNA nanoparticles (DNPs) a potent drug delivery platform. This study focuses on the development of a novel RNA-based siRNA delivery system to knockdown Bcl2 gene, as a targeted cancer therapeutic. By eliminating the use of DNA, the RNA-based nanodelivery can potentially create more robust siRNA delivery vehicles for targeted cancer therapeutics.
