Short double-stranded RNA duplexes are the triggers for post-transcriptional gene silencing and can also induce epigenetic silencing of genes at the level of transcription. A surprising new finding is that short RNA duplexes targeted to promoter regions can also mediate potent enhancement of transcription.
