Transcription profiling of Pseudomonas aeruginosa treated with hydrogen peroxide

Project description:Background: Pseudomonas aeruginosa, a pathogen infecting those with cystic fibrosis, encounters toxicity from phagocyte-derived reactive oxidants including hydrogen peroxide during active infection. P. aeruginosa responds with adaptive and protective strategies against these toxic species to effectively infect humans. Despite advances in our understanding of the responses to oxidative stress in many specific cases, the connectivity between targeted protective genes and the rest of cell metabolism remains obscure. Results: Herein, we performed a genome-wide transcriptome analysis of the cellular responses to hydrogen peroxide in order to determine a more complete picture of how oxidative stress-induced genes are related and regulated. Our data reinforce the previous conclusion that DNA repair proteins and catalases may be among the most vital antioxidant defense systems of P. aeruginosa. Our results also suggest that sublethal oxidative damage reduces active and/or facilitated transport and that intracellular iron might be a key factor for a relationship between oxidative stress and iron regulation. Perhaps most intriguingly, we revealed that the transcription of all F-, R-, and S-type pyocins was upregulated by oxidative stress and at the same time, a cell immunity protein (pyocin S2 immunity protein) was downregulated, possibly leading to self-killing activity. Conclusions: This finding proposes that pyocin production might be another novel defensive scheme against oxidative attack by host cells. Experiment Overall Design: We conducted four and five independent microarray experiments with biological replicates in the absence (control) and the presence (experimental) of hydrogen peroxide, respectively.

Effect of trmA on mRNA expression in Pseudomonas aeruginosa

Project description:tRNA modification involves in regulation of gene expression in bacterial response to environmental stresses. Here, we aimed to study the transcriptional profiling in the absence of trmA, a tRNA uracil-5-methyltransferase, compared to that of the wild type in Pseudomonas aeruginosa PA14 strain using Illumina sequencing. The disruption of trmA resulted in up and down regulated genes in many pathways based on gene ontology biological processes. One of these pathways was heme biosynthesis, in which the genes were down regulated in the trmA mutant. The finding was consistent with hypersensitivity towards hydrogen peroxide in the trmA mutant strain compared to that of the wild-type strain.

Transcriptional modulation of Quoring-sensing signaling throught QslA in Pseudomonas aeruginosa PA14 and PAO1.

Project description:To further determine the origin of the increased virulence of Pseudomonas aeruginosa PA14 compared to Pseudomonas aeruginosa PAO1, we report a transcriptomic approach through RNA sequencing. Next-generation sequencing (NGS) has revolutioned sistems-based analsis of transcriptomic pathways. The goals of this study are to compare the transcriptomic profile of all 5263 orthologous genes of these nearly two strains of Pseudomonas aeruginosa.
