RNA interference (RNAi) is a powerful post-transcriptional gene silencing (PTGS) induced by small double-stranded RNA (dsRNA). The method allows silencing of genes of interest by translation inhibition or by mRNA degradation. In this chapter, we provide a brief overview of the mechanisms involved in each step of gene silencing. A nonviral infusion of short siRNA into ventricular system of rats was used to study purinoceptor in the rat brain.
