Identification of Gene Products Involved in the Oxidative Stress Response of Moraxella catarrhalis: Evaluation of OxyR dependent Genes

Project description:Series of DNA microarrays (4) comparing the M. catarrhalis strain 035E and M. catarrhalis oxyR mutant response to 50 mM hydrogen peroxide. Wild-type cells and oxyR mutant cells were exposed to 50 mM hydrogen peroxide for 15 minutes. RNA was extracted and DNA microarray analysis performed. 4 biologic replicates were studied. One dye swap was included in this series analysis. Control oxyR mutant cells exposed to water

Transcriptome profiling of H. polymorpha in response to hydrogen peroxide exposure

Project description:To gain insight into the basic mechanism of Hydrogen peroxide detoxification in the methylotrophic yeast, H. polymorpha, we analyzed changes in transcriptional profiles in response to hydrogen peroxide exposure. Total RNA samples were collected from H. polymorpha cells after 30 min incubation with 0.5mM hydrogen peroxide. Using the RNA sample obtained prior to hydrogen peroxide addition as a reference, the differential fluorescence intensities of each RNA sample prepared at the indicated time was measured after labeling with Cy3 or Cy5 fluorochromes. For all analyses, we performed dye swapping experiments to avoid dye bias.

Microarray Analysis of Toxicogenomic Effects of Hydrogen Peroxide on Mycobacterium bovis BCG

Project description:In the present study, we employed Affymetrix Mycobacterium bovis BCG GeneChip arrays to investigate the dynamics of global gene expression profiles during the cellular response of Mycobacterium bovis BCG to hydrogen peroxide, which involved initial growth inhibition and metabolism. Keywords: Transcriptome study We conducted three independent microarray experiments (biological replicates) in the absence (control) and the presence (experimental) of hydrogen peroxide. We calculated fold change as the ratio between the signal averages of three untreated (control) and three hydrogen peroxide-treated (experimental) cultures for 0, 10 and 60 min exposures.

Transcription profiling of Arabidopsis under hydrogen peroxide stress overexpressing Zat12

Project description:In this experiment we tested the transcriptome of transgenic Arabidopsis seedlings (5-day-old) constitutively expressing the zinc-finger protein Zat12 (At5g59820) under the control of the 35S-CaMV promoter (Zat12). The transcriptome of these seedlings was compared to that of wild type seedlings grown under the same conditions (WT) and to that of wild type seedlings grown under the same conditions and subjected to a hydrogen peroxide stress (WT+H2O2). Hydrogen peroxide treatment was performed by applying 20 mM hydrogen peroxide for 1 hour. In parallel to these experiments transgenic plants expressing Zat12 were subjected to a similar hydrogen peroxide stress (Zat12+H2O2). All treatments were performed with similar size and age seedlings grown in liquid culture (MS) and sampled at the same time as described by Davletova et al., 2005.

Response of Bacillus pumilus to hydrogen peroxide

Project description:Reactive oxygen species such as hydrogen peroxide occur in all aerobically living organisms. Oxidative stress during fermentation can impair the fitness of the production host and the quality of the product. B. pumilus has been described as highly resistant to hydrogen peroxide. The response of exponentially growing B. pumilus cells to hydrogen peroxide was studied. Two-condition experiment, unstressed versus hydrogen peroxide stressed cells, 3 biological replicates
