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.

Pseudomonas aeruginosa PA14, mvfR and anthranilic acid analogs

Project description:The Pseudomonas aeruginosa MvfR-dependent QS regulatory pathway controls the expression of key virulence genes; and is activated via the extracellular signals 4-hydroxy-2-heptylquinoline (HHQ) and 3,4-dihydroxy-2-heptylquinoline (PQS), whose syntheses depend on anthranilic acid (AA), the primary precursor of 4-hydroxy-2-alkylquinolines (HAQs). We identified halogenated AA analogs that specifically inhibited HAQ biosynthesis and disrupted MvfR-dependent gene expression. These compounds restricted P. aeruginosa systemic dissemination and mortality in mice, without perturbing bacterial viability, and inhibited osmoprotection, a widespread bacterial function.

RNA Sequencing of unc-30(ok613) and wild type (WT) N2 C. elegans in Pseudomonas aeruginosa (PA14) infection

Project description:Purpose: To uncover immune mediated genes and pathways by Pseudomonas aeruginosa infection that are modulated by the homeodomain PITX1/UNC-30, which plays a vital role in the GABAergic signaling in C. elegans Methods: RNA was extracted from synchronized Pseudomonas aeruginosa infected L4 stage unc-30(ok613) and WT using Qiagen extraction kits and following standard methods. The animals were grown on OP50 at 20 C and infected at 25 C. Results: RNA seq analyses shows enriched and signficant Pseudomonas aeruginosa mediated upregulated immune, neuropeptide and metabolism genes and pathways that are dependent of GABAergic signaling Conclusions: Our study uncovered GABAgergic signaling to be modulator of the innate immunity in C elegans during Pseudomonas aeruginosa infection

Proteomics of Pseudomonas aeruginosa PAO1 and PA14

Project description:Recent studies have shown that the concentrations of proteins expressed from orthologous genes are often conserved across organisms, and to a greater extent than the abundances of the corresponding mRNAs. However, such studies have not distinguished between evolutionary (e.g., sequence divergence) and environmental (e.g., growth condition) effects on the regulation of steady-state protein and mRNA abundances. Here we systematically investigated the transcriptome and proteome of two closely related Pseudomonas aeruginosa strains, PAO1 and PA14, under identical experimental conditions, thus controlling for environmental effects. For 703 genes observed by both shotgun proteomics and microarray experiments, we find that the protein-to-mRNA ratios are highly correlated between orthologous genes in the two strains, to an extent comparable to protein and mRNA abundances. In spite of this high molecular similarity between PAO1 and PA14, we found that several metabolic, virulence, and antibiotic resistance genes are differentially expressed between the two strains, mostly at the protein but not at the mRNA level. Our data demonstrate that post-transcriptional regulation is important for understanding the discordance between mRNA and protein abundance.

Expression profile for higA mutant of Pseudomonas aeruginosa PA14

Project description:The previously uncharacterized proteins HigB (unannotated) and HigA (PA4674) of Pseudomonas aeruginosa PA14 were found to form a type II TA system in which antitoxin HigA masks the RNase activity of toxin HigB through direct binding. To determine the physiological role of HigB/HigA in P. aeruginosa, a whole-transcriptome experiment was performed for the higA antitoxin deletion mutant of the PA14 strain compared to the wild-type PA14 strain. The rationale was that for the strain that lacks the antitoxin, the effect of the toxin could be discerned due to enhanced activity of the toxin. Furthermore, toxin HigB reduces production of the virulence factors pyochelin, pyocyanin, swarming, and biofilm formation.
