WebAbstract We expanded the mechanistic capability of small RNAs by creating an entirely synthetic mode of regulation: small transcription activating RNAs (STARs). Using two strategies, we engineered synthetic STAR regulators to disrupt the formation of an intrinsic transcription terminator placed upstream of a gene in Escherichia coli. WebWe recently developed a way to switch on inactive genes in human cells using small RNA molecules instead of viruses, and coined the technique ”RNAa” for RNA-induced gene activation. We have shown that RNAa can induce robust and prolonged activation of a variety of genes.
