Project description:We analysed the gene expression profiles after infection of Staphylococcus aureus at ZT4 in CXCL14-KO mice. The group of genes categolized as GO defense response (GO: 006952) were upregulated upon a response to Staphylococcus aureus infection. The expression of IL1b, Cxcl2, and Ccl3 were significantly suppressed in infected ear of Cxcl14-KO compared to that of WT.
Project description:Young adult fer-15;fem-1 Caenorhabditis elegans were infected with Staphylococcus aureus for 8 h to determine the transcriptional host response to Staphylococcus aureus. Analysis of differential gene expression in C. elegans young adults exposed to two different bacteria: E. coli strain OP50 (control), wild-type Staphylococcus aureus RN6390. Samples were analyzed at 8 hours after exposure to the different bacteria. These studies identified C. elegans genes induced by pathogen infection. Keywords: response to pathogen infection, innate immunity, host-pathogen interactions
Project description:In the present study, we employed Affymetrix Staphylococcus aureus GeneChip arrays to investigate the dynamics of global gene expression profiles during the cellular response of Staphylococcus aureus to peracetic acid, which involved initial growth inhibition and subsequent partial recovery. Keywords: Time course
Project description:In the present study, we employed Affymetrix Staphylococcus aureus GeneChip arrays to investigate the dynamics of global gene expression profiles during the cellular response of Staphylococcus aureus to triclosan, which involved initial growth inhibition and metabolism. Keywords: Transcriptome study; antimicrobial response; time course
Project description:Staphylococcus aureus is one of the most important pathogens in humans and animals, multiply resistant strains are increasingly widespread, new agents are needed for the treatment of S. aureus. Rhein, a natural plant product, has potential antimicrobial activity against Staphylococcus aureus. We employed Affymetrix Staphylococcus aureus GeneChipsTM arrays to investigate the global transcriptional profiling of Staphylococcus aureus ATCC25923 treated with rhein. Results provided insight into mechanisms involved in rhein - Staphylococcus aureus interactions. Keywords: rhein response
Project description:In the present study, we employed Affymetrix Staphylococcus aureus GeneChip arrays to investigate the dynamics of global gene expression profiles during the cellular response of Staphylococcus aureus to hydrogen peroxide-induced oxidative stress, which involved initial growth inhibition and subsequent recovery. Keywords: Time course
Project description:Array analysis of total RNA from broncho-alveolar lavage (BAL) from mice infected with influenza virus (PR8) and/or Staphylococcus aureus (Newman)
Project description:In the present study, we employed Affymetrix Staphylococcus aureus GeneChip arrays to investigate the dynamics of global gene expression profiles during the cellular response of Staphylococcus aureus to Ortho-Phenylphenol, which involved initial growth inhibition and metabolism. Keywords: Time course
