The Brucella abortus virulence regulator, LovhK, is a sensor kinase in the general stress response signaling pathway

ABSTRACT: We sequenced the transcriptomes of B. abortus 2308 wild type, rpoE1, and lovhK deletion strains to assess gene expression in response to oxidative stress. The data represent 2 independent biological replicates of each strain.

Expression Data from Brucella abortus strain 2308 and isogenic mavR mutant cells

Project description:MavR is a 160 nucleotide regulatory RNA molecule that is produced during B. abortus strain 2308 growth in nutrient-replete broth. We used custom-made Affymetrix B. abortus strain 2308 derived GeneChips to compare the gene expression properties of wild type and isogenic mavR mutant cells.

The endoribonuclease YbeY is linked to proper cellular morphology and virulence in Brucella abortus

Project description:The ybeY locus is hypothesized to produce an endoribonuclease, that is expressed during late exponential phase growth and regulate transcript titers. We used custom-made Affymetrix B. abortus strain 2308 derived GeneChips to compare the gene expression properties of wild type and isogenic ybeY mutant cells.

Expression Data from Brucella abortus strain 2308 and isogenic vtlR mutant cells

Project description:VtlR (virulence-associated transcriptional LysR-family regulator) is thought to be a transcriptional regulator of B. abortus virulence determinants We used custom-made Affymetrix B. abortus strain 2308 derived GeneChips to compare the gene expression properties of wild type and isogenic vtlR mutant cells. B. abortus strain 2308 or vltR mutant cells were grown to late exponential phase growth, total bacterial RNA was isolated and subjected to GeneChip hybridization and analysis. We sought to determine the regulatory effects of VtlR.

The Brucella abortus general stress response system is required for chronic animal infection and exhibits noncanonical post-translational regulation

Project description:rpoE1 encodes an extracytoplasmic function (ECF) sigma factor to initiate the transcription of the genes responsible for general stress responses. This experiment is quantifying transcription in two Brucella strains: B. abortus 2308 wild type and rpoE1 in-frame deletion strains (gene bab1_1672).

Expression Data from Brucella abortus strain 2308 and isogenic mucR mutant cells

Project description:MucR is one of the few transcriptional regulatory proteins that has been linked to Brucella pathogenesis. We used custom-made Affymetrix B. abortus strain 2308 derived GeneChips to copare the gene expression properties of wild type and isogenic mucR mutant cells. B. abortus strain 2308 or mucR mutant cells were grown to stationary phase growth, total bacterial RNA was isolated and subjected to GeneChip hybridization and analysis. We sought to determine the regulatory effects of MucR.

Expression Data from Brucella abortus strain 2308 and isogenic abcR1 abcR2 mutant cells

Project description:abcR1 and abcR2 produce two regulatory RNA molecules, that are produced during stationary phase growth. We used custom-made Affymetrix B. abortus strain 2308 derived GeneChips to compare the gene expression properties of wild type and isogenic abcR1 abcR2 double mutant cells. B. abortus strain 2308 or abcR1 abcR2 double mutant cells were grown to stationary phase growth, total bacterial RNA was isolated and subjected to GeneChip hybridization and analysis. We sought to determine the regulatory effects of abcR1 and abcR2 RNA species.
