Project description:Investigation of whole genome expression level changes in Bacillus anthracis Sterne deltaClpX mutant compared to the wild-type strain after growth in nutrient rich media. The deltaClpX mutant used in this study is described in McGillivray et al. 2009. ClpX Protease Contributes to Antimicrobial Peptide Resistance and Virulence Phenotypes of Bacillus anthracis. Journal of Innate Immunity 1(5): 494-506.
Project description:AtxA, the master virulence regulator of Bacillus anthracis, regulates the expression of three toxins that are required for the pathogenicity of Bacillus anthracis. Recent transcriptome analyses also showed that AtxA affects a large number of genes on both chromosome and plasmid, suggesting its role as a global regulator. Its mechanism of gene regulation nor binding target in vivo was, however, not well understood. In this work, we conducted ChIP-seq for cataloging binding sites of AtxA in vivo and Cappable-seq for catalogging the transcription start sites on the B. anthracis genome. For detected regulons, single knockout strains were constructed and RNA-seq was conducted for each strain.
Project description:hole Genome Expression Profile of Human Peripheral Blood Mononuclear cells Exposed to Bacillus anthracis in vitro. Peripheral blood mononuclear cells exposed to a 1 MOI (multiplicity of infection pathogenic) of the B. anhracis spores. Human Peripheral Blood Mononuclear cells Exposed to Bacillus anthracis in vitro
Project description:The High Temperature Requirement (HtrA) chaperone/protease is involved in the stress-response of the anthrax-causing pathogen Bacillus anthracis. Resilience to oxidative stress is essential for manifestation of B. anthracis pathogenicity. We submitt transcriptome data sets detailing global gene expression in B. anthracis wild-type and htrA-disrupted strains following H2O2-induced oxidative stress.
