- Abstract
- In most applications, small interfering RNAs are designed to execute specific gene silencing via RNA interference (RNAi) without triggering nonspecific responses such as immunostimulation. However, in anticancer therapeutics, immunostimulation combined with specific oncogene silencing could be beneficial, resulting in the synergistic inhibition of cancer cell growth. In this study, we report an immunostimulatory long double-stranded RNA (dsRNA) structure with the ability to trigger RNAi-mediated specific target gene silencing, termed as long interfering dsRNA (liRNA). liRNA targeting Survivin mRNA not only efficiently and specifically triggered target gene silencing via RNAi, but also stimulated the protein kinase R pathway to induce the expression of interferon beta. As a result, the ability of Survivin-targeting liRNA to inhibit cancer cell growth was superior over conventional small interfering RNA or nontargeting dsRNA structures. Our results thus provide a simple yet efficient dual function immunostimulatory RNAi-triggering structure, which is potentially applicable for the development of anticancer therapeutics.
