Gene expression analysis of Salmonella enterica serovar Typhimurium strain SL1344 swap

ABSTRACT: We performed transcriptome abundance analysis of Salmonella Typhimurium strain SL1344 swap which has been genetically engineered to express the hns open-reading frame from the stpA promoter and the stpA open reading frame from the hns promoter. This strain is designated SL1344(swap). Transcript abundance was compared with that of wild-type SL1344. This comparison was performed to determine the effect of chromosome location of the expression of two related global regulators and how alterations to their expression patterns would impact on their regulons.

Gene expression analysis of Salmonella enterica serovar Typhimurium strain SL1344 swap

Project description:We performed transcriptome abundance analysis of Salmonella Typhimurium strain SL1344 swap which has been genetically engineered to express the hns open-reading frame from the stpA promoter and the stpA open reading frame from the hns promoter. This strain is designated SL1344(swap). Transcript abundance was compared with that of wild-type SL1344. This comparison was performed to determine the effect of chromosome location of the expression of two related global regulators and how alterations to their expression patterns would impact on their regulons. Three independent RNA samples were harvested from wild-type SL1344 and SL1344(swap) grown to exponential phase (OD600nm = 0.3) and hybridized to a microarray containing multiple probes for each of the SL1344 open reading frames. Please note that the original raw data file for the 'SL1344_wildtype_BR2' sample is unavailable, however, the 'wildtype SL1344 BR2.gpr' contains the raw data missing only the header information.

Transcriptomic study of single mutants hns, hns2 and double mutans hhahha2 and hnshns2 from enteroaggregative E. coli 042 by RNA-seq

Project description:Bacterial genomes encode in many instances more than one copy of genes coding for global modulators. In the Enterobacteriaceae, cells express the global modulator H-NS and its paralogue StpA. The enteroaggregative E. coli strain 042 encodes, in addition to the hns and stpA genes, an additional hns gene. We used RNA-seq to compare the transcriptome of the wt strain and its hns, hns2 and double hns hns2 derivatives, as well as of an hha null mutant (hhahha2). It is well known that the Hha protein co-modulates gene expression with H-NS. The results obtained have shown that the main role of H-NS2 is to modulate a subset of H-NS modulated genes, those that also are targeted by Hha, which are mainly HGT genes. When compared with H-NS, H-NS2 also shows a differential expression level and a different regulatory pattern.

Dual RNA regulator VcdRP in V. cholerae modulates central metabolism

Project description:Bacterial small RNAs (sRNAs) are well-known to modulate gene expression by base-pairing with trans-coded transcripts and are typically considered to be non-coding. However, several sRNAs have been reported to also contain an open reading frame and thus are considered dual-function regulators. We discovered a dual-function regulator from Vibrio cholerae, called VcdRP, harboring a 29 amino acid protein (VcdP), as well as a base-pairing sequence. In this study, we measured the metabolite abundance of glycolytic and citric acid cycle intermediates using LC-MS.
