An RNA Thermosensor Controls Expression of Virulence Genes in Listeria monocytogenes
In Listeria monocytogenes, virulence genes are maximally expressed at 37 degrees C, almost silent at 30 degrees C and controlled by PrfA, a transcriptional activator whose expression isExpand

A trans-Acting Riboswitch Controls Expression of the Virulence Regulator PrfA in Listeria monocytogenes
Riboswitches are RNA elements acting in cis, controlling expression of their downstream genes through a metabolite-induced alteration of their secondary structure. Here, we demonstrate that twoExpand

A new Vibrio cholerae sRNA modulates colonization and affects release of outer membrane vesicles
We discovered a new small non‐coding RNA (sRNA) gene, vrrA of Vibrio cholerae O1 strain A1552. A vrrA mutant overproduces OmpA porin, and we demonstrate that the 140 nt VrrA RNA represses ompAExpand

VirR, a response regulator critical for Listeria monocytogenes virulence
Signature‐tagged mutagenesis (STM) was used to identify new genes involved in the virulence of the Gram‐positive intracellular pathogen Listeria monocytogenes. One of the mutants isolated by thisExpand

Differential protease-mediated turnover of H-NS and StpA revealed by a mutation altering protein stability and stationary-phase survival of Escherichia coli.
The Escherichia coli proteins H-NS is recognized as an important component among the major nucleoid-associated proteins. In studies of E. coli strains with defects in H-NS, we discovered a mutantExpand

Expanded CAG repeats in Swedish spinocerebellar ataxia type 7 (SCA7) patients: effect of CAG repeat length on the clinical manifestation.
Spinocerebellar ataxia 7 (SCA7) is a neurodegenerative disorder characterized by degeneration of the cerebellum, brainstem and retina. The gene responsible for SCA7, located on chromosome 3p,Expand

Foundation damping and the dynamics of offshore wind turbine monopiles
The contribution of foundation damping to offshore wind turbines (OWTs) is not well known, though researchers have back-calculated foundation damping from “rotor-stop” tests after estimatingExpand

A riboswitch-regulated antisense RNA in Listeria monocytogenes
Riboswitches are ligand-binding elements located in 5′ untranslated regions of messenger RNAs, which regulate expression of downstream genes. In Listeria monocytogenes, a vitamin B12-binding (B12)Expand

Heteromeric interactions among nucleoid-associated bacterial proteins: localization of StpA-stabilizing regions in H-NS of Escherichia coli.
The nucleoid-associated proteins H-NS and StpA in Escherichia coli bind DNA as oligomers and are implicated in gene regulatory systems. There is evidence for both homomeric and heteromeric H-NS-StpAExpand

Cycles of light and dark co-ordinate reversible colony differentiation in Listeria monocytogenes
Recently, several light receptors have been identified in non‐phototrophic bacteria, but their physiological roles still remain rather elusive. Here we show that colonies of the saprophytic bacteriumExpand
