Sequential packaging of RNA genomic segments during the assembly of Bluetongue virus. [PDF]
, 2014 Bluetongue virus (BTV), a member of the Orbivirus genus within the Reoviridae family, has a genome of 10 double-stranded RNA segments, with three distinct size classes.

Cell Reports, 2014 Double-stranded RNA (dsRNA) can function as genetic information and may have served as genomic material before the existence of DNA-based life. By developing a method to purify dsRNA, we have investigated the diversity of dsRNA in microbial populations ...

UPF1 promotes the formation of R loops to stimulate DNA double-strand break repair
Nature Communications, 2021 R loops are formed when single-stranded RNA anneals to one strand of DNA, forming three-stranded structures containing DNA-RNA hybrids and the displaced non-template single-stranded DNA. Here the authors reveal that the DNA:RNA helicase UPF1 plays a role

Mismatched Double-Stranded RNA [PDF]
Drugs in R & D, 2004 Ampligen [polyI:polyC12U] is a mismatched double-stranded RNA that acts by inducing interferon production (immunomodulator) and by activating an intracellular enzyme (RNase-L) against viral RNA transcripts (antiviral). Ampligen, currently under development by Hemispherx Biopharma in the US, acts on the immunological system through T-lymphocyte ...

The influence of viral RNA secondary structure on interactions with innate host cell defences [PDF]
, 2013 RNA viruses infecting vertebrates differ fundamentally in their ability to establish persistent infections with markedly different patterns of transmission, disease mechanisms and evolutionary relationships with their hosts.

Single-molecule conductance of double-stranded RNA oligonucleotides
, 2021 RNA oligonucleotides are crucial for a range of biological functions and in many biotechnological applications. Herein, we measured, for the first time, the conductance of individual double-stranded (ds)RNA molecules and compared it with the conductance ...

Efficiency of RNA interference is improved by knockdown of dsRNA nucleases in tephritid fruit flies [PDF]
Open Biology, 2019 RNA interference (RNAi) in insects is routinely used to ascertain gene function, but also has potential as a technology to control pest species. For some insects, such as beetles, ingestion of small quantities of double-stranded RNA (dsRNA) is able to ...

Targeting mitochondrial metabolites and nucleic acids as an anti-inflammatory strategy
Frontiers in Drug Discovery, 2023 Mitochondrial metabolites and their derivatives have been the focus of recent efforts to develop new anti-inflammatory therapeutics. The widely used therapeutic agents dimethyl fumarate (DMF) and metformin have anti-inflammatory properties and have been ...

Action of Nucleases on Double‐Stranded RNA [PDF]
European Journal of Biochemistry, 1976 Double‐stranded RNAs from Penicillium chrysogenum virus have been treated with RNAse III, pancreatic RNAse A and RNAse T1 and the degradation of the RNAs has been studied under different conditions. It was found that only the two former enzymes cut across both strands, RNase T1 cannot cleave double strands.RNase III was shown to digest double‐stranded ...

Tracking Cryptosporidium parvum by Sequence Analysis of Small Double-Stranded RNA
Emerging Infectious Diseases, 2001 We sequenced a 173-nucleotide fragment of the small double-stranded viruslike RNA of Cryptosporidium parvum isolates from 23 calves and 38 humans. Sequence diversity was detected at 17 sites.
