dsRNA Uptake in Adult Drosophila [PDF]

open access: yes, 2011
RNA interference (RNAi) is a conserved sequence-specific gene silencing mechanism that is induced by double-stranded RNA (dsRNA). The development of methods that allow internalization of dsRNA and concomitant silencing of the desired gene has not stopped since the first demonstration of RNAi in Caenorhabditis elegans.

Mechanism of PKR Activation by dsRNA [PDF]

open access: yesJournal of Molecular Biology, 2008
Protein kinase R (PKR) is a central component of the interferon antiviral defense pathway. Upon binding double-stranded RNA (dsRNA), PKR undergoes autophosphorylation reactions that activate the kinase. PKR then phosphorylates eukaryotic initiation factor 2alpha, thus inhibiting protein synthesis in virally infected cells.

Double strand RNA-mediated RNA interference through feeding in larval gypsy moth, Lymantria dispar (Lepidoptera: Erebidae)

open access: yesEuropean Journal of Entomology, 2017
RNA interference (RNAi) technology uses dsRNAs to silence specific targeted genes by downregulating their expression. It has become a potent tool for functional and regulatory studies of insect genes and has potential to be applied for insect control ...

Structural basis for Dicer-like function of an engineered RNase III variant and insights into the reaction trajectory of two-Mg2+-ion catalysis

open access: yesRNA Biology, 2022
The RNase III family of dsRNA-specific endonucleases is exemplified by prokaryotic RNase III and eukaryotic Rnt1p, Drosha, and Dicer. Structures of Aquifex aeolicus RNase III (AaRNase III) and Saccharomyces cerevisiae Rnt1p (ScRnt1p) show that both ...

Microinjection of dsRNA in Tardigrades [PDF]

open access: yesCold Spring Harbor Protocols, 2018
Classical genetic analysis in the tardigrade Hypsibius exemplaris is a challenge because these animals are parthenogens. The publication of the H. exemplaris genome has facilitated the study of targeted genes by RNA interference (RNAi), a robust mechanism to disrupt gene function. This protocol describes microinjection of double-stranded RNA (dsRNA) in

RNAi-mediated gene silencing in Rhynchophorus ferrugineus (Oliver) (Coleoptera: Curculionidae)

open access: yesOpen Life Sciences, 2017
RNA interference (RNAi) is a powerful strategy for gene function analysis, and it is also widely studied in view of a promising use in pest control. The red palm weevil, Rhynchophorus ferrugineus (Oliver) (Coleoptera: Curculionidae), is one of the most ...

An Investigation of Innate Immune Response of Human Blood Macrophage to Sense and Antisense dsRNA

open access: yesTrends in Peptide and Protein Sciences, 2016

Barriers to Efficient Foliar Uptake of dsRNA and Molecular Barriers to dsRNA Activity in Plant Cells [PDF]

open access: yesFrontiers in Plant Science, 2020
Foliar application of dsRNA to elicit an RNA interference (RNAi) response is currently under consideration as a crop protection strategy. To access the RNAi machinery of a plant, foliarly applied dsRNAs must traverse the plant cuticle, avoid nuclease degradation, and penetrate the cell wall and plasma membrane.

Quelling an innate response to dsRNA

open access: yesOncotarget, 2015
The interferon inducible oligoadenylate synthetase (OAS)/RNase L pathway is an innate defense against invading viral pathogens that is linked to cell survival [reviewed in 1]. OAS family proteins are pattern recognition receptors that recognize double-stranded RNA (dsRNA), a pathogen-associated molecular pattern.
