UPF1 promotes the formation of R loops to stimulate DNA double-strand break repair

open access: yesNature 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

In vitro antiviral activity of a double-stranded RNA sodium salt-based medicinal product against SARS-CoV-2

open access: yesБиопрепараты: Профилактика, диагностика, лечение, 2023
Scientific relevance. Innate immune activation in the early phases of COVID-19 infection and subsequent interferon induction may help control viral replication and protect cells not yet infected with SARS-CoV-2.

Tat-responsive region RNA of human immunodeficiency virus 1 can prevent activation of the double-stranded-RNA-activated protein kinase [PDF]

open access: yes, 1990
Transcription from the human immunodeficiency virus type 1 promoter gives rise to short cytoplasmic transcripts of approximately 60 nucleotides as well as to longer mRNAs.

Mismatched Double-Stranded RNA [PDF]

open access: yesDrugs 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 ...

Supercoiling Double-Stranded RNA [PDF]

open access: yesBiophysical Journal, 2010
Through a novel "polymerase-stall" labeling procedure, we have successfully generated torsionally constrained molecules of double-stranded RNA (dsRNA). We have anchored these molecules within a magnetic tweezers apparatus, and by rotating the magnets, induced both positive and negative supercoils within these molecules.

Assessment of RNAi-induced silencing in banana (Musa spp.) [PDF]

open access: yes, 2015
In plants, RNA- based gene silencing mediated by small RNAs functions at the transcriptional or post-transcriptional level to negatively regulate target genes, repetitive sequences, viral RNAs and/or transposon elements.

Efficiency of RNA interference is improved by knockdown of dsRNA nucleases in tephritid fruit flies [PDF]

open access: yesOpen 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 ...

New insights into the biological role of mammalian ADARs; the RNA editing proteins [PDF]

open access: yes, 2015
The ADAR proteins deaminate adenosine to inosine in double-stranded RNA which is one of the most abundant modifications present in mammalian RNA.

Targeting mitochondrial metabolites and nucleic acids as an anti-inflammatory strategy

open access: yesFrontiers 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 ...

Evidence that avian reovirus σNS is an RNA chaperone: implications for genome segment assortment. [PDF]

open access: yes, 2015
Reoviruses are important human, animal and plant pathogens having 10-12 segments of double-stranded genomic RNA. The mechanisms controlling the assortment and packaging of genomic segments in these viruses, remain poorly understood.
