Differential transcriptome profiling of P. aeruginosa PAO1 with oxythiamine treatment

ABSTRACT: We report antibacterial potency of oxythiamine, which is a known transketolase inhibitor in eukaryotes. Oxythiamine inhibited the growth of P. aeruginosa PAO1 and clinical isolates in thiamine-depleted medium only. Metabolic and trascriptomic analyses indicated that oxythiamine was converted to oxythiamine pyrophosphate that subsequently inhibited several vitamin B1-dependent enzymes. Furthermore, a system-level perturbation of thiamine metabolism sensitized P. aeruginosa to multiple small-molecules informing the potential development of a rational drug combination.

Next Generation Sequencing Facilitates Quantitative Analysis of control of Pseudomonas aeruginosa PAO1 and farnesol-treated P. aeruginosa PAO1 Transcriptomes

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare transcriptome profiling of control of P. aeruginosa PAO1 (RNA-seq) to transcriptome profiling of farnesol-treated P. aeruginosa PAO1 and to evaluate protocols for optimal high-throughput data analysis. Methods:LB medium (50 mL) was inoculated with exponential growth phase P. aeruginosa PAO1 at a concentration of 108 CFU/mL. Farnesol was then added at a concentration of either 0 (control) or 0.56 mg/mL, in triplicate. All six experiment groups were incubated in a water bath shaker at 37 ºC with a shaking rate of 180 rpm for 5 h. Cells were then sampled and centrifuged from the three control groups and three farnesol treatment groups, respectively. The cell precipitates were separately snap-frozen at -80ºC. Total RNA was isolated from cells using Trizol (Life Technologies, USA) according to the manufacturer’s protocol. Results: Our RNA-seq results showed that less than 100 genes of P. aeruginosa PAO1 were differentially expressed following farnesol treatment. We found that about 1.7% of all detected genes (96 of 5554 genes) were more than two-fold differentially expressed following farnesol treatment. Conclusions:

PAHM4 vs PAO1 37C LB

Project description:Pseudomonas aeruginosa strains PAHM4 and PAO1 were grown at 37C on LB and RNA was hybridized on the Affymetrix P. aeruginosa chip to compare transcript differences from a BQ isolate to a well characterized wound isolate. Strains PAHM4 and PAO1 were grown in triplicate. Total RNA from each sample was pooled and amplified then assayed in triplicate resulting in 6 total samples. PAO1 is the control strain while PAHM4 is the experimental strain.

Microarray analysis of P. aeruginosa PAO1 expression PA5060 (phaF) on pJN105

Project description:The Pseudomonas aeruginosa PAO1 gene phaF (PA5060) is a transcriptional regulator in the closely related pseudomonad P. putida. phaF is expressed at higher levels in P. aeruginosa clinical isolates from the cystic fibrosis respiratory tract. To determine the role of phaF in regulating P. aeruginosa gene expression, we cloned it under control of the pBAD promoter in expression vector pJN105 and compared expression in this strain relative to an empty vector control strain. We used microarrays to study overall gene expression in a P. aeruginosa PAO1 phaF overexpression strain. A P. aeruginosa PAO1 strain over-expressing the transcriptional regulator phaF, PAO1 pJN105-phaF, and the corresponding empty control strain, P. aeruginosa PAO1 pJN105, were grown to exponential phase, RNA was isolated, and gene expression was analyzed via microarray analysis and compared.
