Inference of Bacterial Small RNA Regulatory Networks and Integration with Transcription Factor-Driven Regulatory Networks

mSystems, 2020
Small noncoding RNAs (sRNAs) are key regulators of bacterial gene expression. Through complementary base pairing, sRNAs affect mRNA stability and translation efficiency.

Discovery of the major 15–30 nt mammalian small RNAs, their biogenesis and function

Nature Communications, 2023
Small RNAs (sRNAs) within 15-30 nt such as miRNA, tsRNA, srRNA with 3’-OH have been identified. However, whether these sRNAs are the major 15-30 nt sRNAs is still unknown.

Kinetic modeling reveals additional regulation at co-transcriptional level by post-transcriptional sRNA regulators

Cell Reports, 2021
Summary: Small RNAs (sRNAs) are important gene regulators in bacteria. Many sRNAs act post-transcriptionally by affecting translation and degradation of the target mRNAs upon base-pairing interactions. Here we present a general approach combining imaging

Identification and Regulatory Roles of a New Csr Small RNA from Arctic Pseudoalteromonas fuliginea BSW20308 in Temperature Responses

Microbiology Spectrum, 2023
Small RNAs (sRNAs) play a very important role in gene regulation at the posttranscriptional level. However, sRNAs from nonmodel microorganisms, extremophiles in particular, have been rarely explored.

Predicting sRNAs and Their Targets in Bacteria

Genomics, Proteomics & Bioinformatics, 2012
Abstract Bacterial small RNAs (sRNAs) are an emerging class of regulatory RNAs of about 40–500 nucleotides in length and, by binding to their target mRNAs or proteins, get involved in many biological processes such as sensing environmental changes and regulating gene expression.

Evolution of plasticity in production and transgenerational inheritance of small RNAs under dynamic environmental conditions.

PLoS Genetics, 2021
In a changing environment, small RNAs (sRNAs) play an important role in the post-transcriptional regulation of gene expression and can vary in abundance depending on the conditions experienced by an individual (phenotypic plasticity) and its parents (non-

Identification of oligo-adenylated small RNAs in the parasite Entamoeba and a potential role for small RNA control

BMC Genomics, 2020
Background The RNA interference (RNAi) pathway is a gene regulation mechanism that utilizes small RNA (sRNA) and Argonaute (Ago) proteins to silence target genes.

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,
