Conjugal transfer of the Salmonella enterica virulence plasmid in the mouse intestine
(American Society for Microbiology, 2008)
BALB/c mice were infected with two Salmonella enterica serovar Typhimurium strains, one of which lacked the virulence plasmid. Transconjugants were found at high frequencies in the mouse feces and at low frequencies in the ...

The THP1-SAC3-SUS1-CDC31 complex works in transcription elongation-mRNA export preventing RNA-mediated genome instability
(American Society for Cell Biology, 2008)
The eukaryotic THO/TREX complex, involved in mRNP biogenesis, plays a key role in the maintenance of genome integrity in yeast. mRNA export factors such as Thp1-Sac3 also affect genome integrity, but their mutations have ...

A novel class of Mrna-containing cytoplasmic granules are produced in response to UV-irradiation
(American Society for Cell Biology, 2008)
Nucleic acids are substrates for different types of damage, but little is known about the fate of damaged RNAs. We addressed the existence of an RNA-damage response in yeast. The decay kinetics of GAL1p-driven mRNAs revealed ...

Insertion hot spot for horizontally acquired DNA within a bidirectional small-RNA locus in Salmonella enterica
(American Society for Microbiology, 2008)
In Escherichia coli and Salmonella enterica, RyeA and RyeB RNAs are encoded on opposite DNA strands at the same locus. We present evidence indicating that the last 23 bp of the ryeB gene, corresponding to an internal portion ...

Regulation of the Salmonella enterica std fimbrial operon by DNA adenine methylation, SeqA, and HdfR
(American Society for Microbiology, 2008)
DNA adenine methylase (dam) mutants of Salmonella enterica serovar Typhimurium grown under laboratory conditions express the std fimbrial operon, which is tightly repressed in the wild type. Here, we show that uncontrolled ...
