RNAi and retroviruses: are they in RISC?

Biomolecular Concepts, 2013
RNA interference (RNAi) is a potent cellular system against viruses in various organisms. Although common traits are observed in plants, insects, and nematodes, the situation observed in mammals appears more complex.

RNA-directed DNA methylation involves co-transcriptional small-RNA-guided slicing of polymerase V transcripts in Arabidopsis. [PDF]

, 2018
Small RNAs regulate chromatin modifications such as DNA methylation and gene silencing across eukaryotic genomes. In plants, RNA-directed DNA methylation (RdDM) requires 24-nucleotide small interfering RNAs (siRNAs) that bind to ARGONAUTE 4 (AGO4) and ...

Altered Hippocampal Transcriptomic Profile Reveals Cognitive Impairment in Young Metabolically Obese, Normal‐Weight Rats, Prevented by Perinatal Leptin Intake

Molecular Nutrition &Food Research, EarlyView.
Early‐life exposure of rats to high‐fat‐isocaloric diet leads to metabolically obese, normal‐weight phenotype, and impaired cognition. Hippocampal transcriptomic analysis reveals disruption in pathways linked to obesity and cognitive decline, which is mitigated by perinatal leptin supplementation. PBMC share common altered genes with hippocampus, which

DNA recognition by an RNA-guided bacterial Argonaute. [PDF]

PLoS ONE, 2017
Argonaute (Ago) proteins are widespread in prokaryotes and eukaryotes and share a four-domain architecture capable of RNA- or DNA-guided nucleic acid recognition. Previous studies identified a prokaryotic Argonaute protein from the eubacterium Marinitoga

Knockdown of piRNA pathway proteins results in enhanced Semliki forest virus production in mosquito cells [PDF]

, 2013
The exogenous siRNA pathway is important in restricting arbovirus infection in mosquitoes. Less is known about the role of the PIWI-interacting RNA pathway, or piRNA pathway, in antiviral responses. Viral piRNA-like molecules have recently been described

Sural/Radial Amplitude Ratio: A Useful Tool to Diagnose Non‐Length‐Dependent Neuropathy

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Patients with non‐length‐dependent neuropathy (NLDN) exhibit reduced sensory nerve action potential (SNAP) amplitudes in both lower and upper limbs. This study aimed to determine a threshold for the sural/radial amplitude ratio (SRAR) suggestive of NLDN.

Target RNAs strike back on MicroRNAs [PDF]

, 2018
MicroRNAs are extensively studied regulatory non-coding small RNAs that silence animal genes throughout most biological processes, typically doing so by binding to partially complementary sequences within target RNAs.

Control of two sucking insect pests, a whitefly (Bemisia tabaci) and a thrips (Frankliniella occidentalis), infesting hot peppers by spraying LDH‐formulated dsRNA

Pest Management Science, EarlyView.
A vacuolar type ATPase subunit B (vATPase‐B) gene is identified and expressed in the midgut of Bemisia tabaci and Frankliniella occidentalis. The double‐stranded RNA (dsRNA) specific to vATPase‐B was expressed in hot peppers by virus‐induced gene silencing (VIGS) and killed both whitefly and thrips.

The RabGAP TBC-11 controls Argonaute localization for proper microRNA function in C. elegans.

PLoS Genetics, 2021
Once loaded onto Argonaute proteins, microRNAs form a silencing complex called miRISC that targets mostly the 3'UTR of mRNAs to silence their translation. How microRNAs are transported to and from their target mRNA remains poorly characterized.

A novel class of microRNA-recognition elements that function only within open reading frames. [PDF]

, 2018
MicroRNAs (miRNAs) are well known to target 3' untranslated regions (3' UTRs) in mRNAs, thereby silencing gene expression at the post-transcriptional level.
