Ultrastructure of influenza virus ribonucleoprotein complexes during viral RNA synthesis
Communications Biology, 2021 Nakano et al. use high-speed AFM and cryo-EM to study influenza virus RNA synthesis in vitro. They observe the synthesis of two types of RNA: folded single stranded RNA associated to an intact viral ribonucleoprotein (vRNP) and looped, double stranded ...

Contribution of Small RNA Pathway to Interactions of Rice with Pathogens and Insect Pests
Rice, 2021 Small RNAs (sRNAs) are mainly classified into microRNAs (miRNAs) and small interfering RNAs (siRNAs) according to their origin. miRNAs originate from single-stranded RNA precursors, whereas siRNAs originate from double-stranded RNA precursors that are ...

Double Stranded RNA in Human Seminal Plasma
Frontiers in Genetics, 2017 Recently, human semen was shown to contain cell-free nucleic acids, such as DNA, long single stranded RNA, and small RNAs–miRNA and piRNA. The RNAs have been suggested to have potential biological roles as communication molecules between cells and in the

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

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 ...

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 ...

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 ...

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 ...

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.
