RNA-dependent RNA polymerases in RNA silencing
Biological Chemistry, 2011Abstract RNA-dependent RNA polymerases (RdRPs) synthesize double-stranded RNAs that are processed into small RNAs and mediate gene silencing. Viral RdRPs and cellular RdRPs show little structural homology to each other. Cellular RdRPs play key roles in RNA silencing by producing complementary strands for target RNAs via Dicer-dependent and -

RNA Editing with Viral RNA-Dependent RNA Polymerase
ACS Synthetic Biology, 2022RNA editing is currently attracting attention as a method for editing genetic information without injury to the genome. The most common approach to edit RNA sequences involves the induction of an A-to-I change by adenosine deaminase acting on RNA (ADAR). However, this method only allows point editing.

RNA Libraries and RNA Recognitiona
Annals of the New York Academy of Sciences, 1996Random RNA libraries, consisting of > 10(13) unique sequences, contain molecules capable of specifically binding small molecule and protein ligands by noncovalent interaction. Successive steps of affinity purification and amplification allow the propagation and eventual isolation of specific binding molecules, called aptamers.

Architecture of RNA–RNA interactions
Current Opinion in Genetics & Development, 2022RNA molecules tend to form intricate tertiary structures via intramolecular RNA-RNA interactions (RRIs) to regulate transcription, RNA processing, and translation processes. In these biological processes, RNAs, especially noncoding RNAs, usually achieve their regulatory specificity through intermolecular RNA-RNA base pairing and execute their ...

Nanostructured RNAs for RNA Interference
2014We synthesized three types of nanostructured RNAs that induce RNA interference (RNAi): branched RNAs, dumbbell-shaped RNA, and circular double-stranded RNAs. All three nanostructured RNAs were transformed into double-stranded RNA of approximately 20 base pairs when they were treated with nuclease enzymes such as Dicer.
