Abstract

The promise of RNA interference (RNAi) technology in cancer therapeutics aims to deliver small interfering RNA (siRNA) for silencing of gene expression in cell type-specific pathway. However, the challenge for the delivery of stable siRNA is hindered by an immune-hostile tumor microenvironment and physiological barriers of the circulatory system. Therefore, the development and validation of safe, stable, and efficient nanoengineered delivery systems are highly essential for effective delivery of siRNA into cancer cells. This review focuses on gene-silencing mechanisms, challenges to siRNA delivery, design and delivery of nanocarrier systems, ongoing clinical trials, and translational prospects for siRNA-mediated cancer therapeutics.
