Conserved mycobacterial sRNA B11 regulates lipooligosaccharide synthesis at posttranscriptional level in Mycobacterium marinum

mLife, Volume 4, Issue 4, Page 447-460, August 2025.
Abstract Extractable glycolipids of mycobacteria, such as lipooligosaccharides (LOSs), play crucial roles in responding to environmental stress and modulating the host immune response. Although the biosynthesis of LOS is likely regulated at multiple levels to ensure proper composition of the cell wall, the key regulators remain unknown.

Dynamic transition in Landau-Zener-St\"uckelberg interferometry of dissipative systems: the case of the flux qubit [PDF]

, 2016
We study Landau-Zener-Stuckelberg (LZS) interferometry in multilevel systems coupled to an Ohmic quantum bath. We consider the case of superconducting flux qubits driven by a dc+ac magnetic fields, but our results can apply to other similar systems.

Epigallocatechin Gallate Remodelling of Hfq Amyloid-Like Region Affects Escherichia coli Survival

Pathogens, 2018
Hfq is a pleiotropic regulator that has key roles in the control of genetic expression. The protein noticeably regulates translation efficiency and RNA decay in Gram-negative bacteria, due to the Hfq-mediated interaction between small regulatory ...

Extracellular Vesicles From Xylella fastidiosa Carry sRNAs and Genomic Islands, Suggesting Roles in Recipient Cells

Journal of Extracellular Vesicles, Volume 14, Issue 6, June 2025.
ABSTRACT Xylella fastidiosa (Xf) is a Gram‐negative bacterial plant pathogen responsible for severe diseases in a variety of economically important crops. A critical aspect of its virulence is the production of extracellular vesicles (EVs). In this study, we discovered that DNA‐binding proteins and nonribosomal RNA‐binding proteins are abundant in the ...

Hfq affects mRNA levels independently of degradation [PDF]

BMC Molecular Biology, 2010
Abstract Background The bacterial Lsm protein, Hfq, is an RNA chaperone involved in many reactions related to RNA metabolism, such as replication and stability, control of small RNA activity and polyadenylation. Despite this wide spectrum of known functions, the global role of Hfq is almost certainly undervalued; its ...

Non‐conserved microRNAs and their roles in plants: the case for legumes

Plant Biology, Volume 27, Issue 4, Page 450-460, June 2025.
Non‐conserved miRNAs are functional and modulate stress and microbial interactions in legumes, hinting at broader roles in plant gene regulation. Abstract Several classes of small RNAs function to regulate stress and development pathways in all kingdoms of life.

Functional Characterization of a Global Virulence Regulator Hfq and Identification of Hfq-Dependent sRNAs in the Plant Pathogen Pantoea ananatis

Frontiers in Microbiology, 2019
To successfully infect plant hosts, the collective regulation of virulence factors in a bacterial pathogen is crucial. Hfq is an RNA chaperone protein that facilitates the small RNA (sRNA) regulation of global gene expression at the post-transcriptional ...
