摘要：

RNAi using single-strand RNA would provide new options for therapeutic development and for investigating critical questions of mechanism. Using chemically modified single-strands, we test the hypothesis that single-stranded RNAs can engage the RNAi pathway and silence gene transcription. We find that a chemically modified single-stranded silencing RNA (ss-siRNA) designed to be complementary to a long noncoding RNA (IncRNA) requires argonaute protein, functions through the RNAi pathway, and inhibits gene transcription. These data expand the use of single-stranded RNA to cell nuclei.
