Hfq binding changes the structure of Escherichia coli small noncoding RNAs OxyS and RprA, which are involved in the riboregulation of rpoS [PDF]
, 2013 OxyS and RprA are two small noncoding RNAs (sRNAs) that modulate the expression of rpoS, encoding an alternative sigma factor that activates transcription of multiple Escherichia coli stress-response genes. While RprA activates rpoS for translation, OxyS

Grad‐seq in a Gram‐positive bacterium reveals exonucleolytic sRNA activation in competence control
EMBO Journal, 2020 RNA–protein interactions are the crucial basis for many steps of bacterial gene expression, including post‐transcriptional control by small regulatory RNAs (sRNAs). In stark contrast to recent progress in the analysis of Gram‐negative bacteria, knowledge

Hierarchy in Hfq Chaperon Occupancy of Small RNA Targets Plays a Major Role in Their Regulation
Cell Reports, 2020 Summary: Bacterial small RNAs (sRNAs) are posttranscriptional regulators of gene expression that base pair with complementary sequences on target mRNAs, often in association with the chaperone Hfq. Here, using experimentally identified sRNA-target pairs,

Identification of small RNAs abundant in Burkholderia cenocepacia biofilms reveal putative regulators with a potential role in carbon and iron metabolism [PDF]
, 2017 Small RNAs play a regulatory role in many central metabolic processes of bacteria, as well as in developmental processes such as biofilm formation. Small RNAs of Burkholderia cenocepacia, an opportunistic pathogenic beta-proteobacterium, are to date not ...

A novel mechanism underlying the innate immune response induction upon viral-dependent replication of host cell mRNA: A mistake of +sRNA viruses' replicases [PDF]
, 2017 Viruses are lifeless particles designed for setting virus-host interactome assuring a new generation of virions for dissemination. This interactome generates a pressure on host organisms evolving mechanisms to neutralize viral infection, which places the

Myths about violence among judiciary professionals [PDF]
Temida, 2006 The presence of myths about violence (mistaken, but resilient and broadly shared opinions) among those professionals who deal with violence in their work could interfere with their educational advancement and professional development.

ARGONAUTE PIWI domain and microRNA duplex structure regulate small RNA sorting in Arabidopsis. [PDF]
, 2014 Small RNAs (sRNAs) are loaded into ARGONAUTE (AGO) proteins to induce gene silencing. In plants, the 5'-terminal nucleotide is important for sRNA sorting into different AGOs.
