Expression profile for higA mutant of Pseudomonas aeruginosa PA14

ABSTRACT: 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.

Microarray for suspension cells of PA14 WT with and without NE (50 uM and 500 uM) for 7 h

Project description:It has been proposed that the gastro-intestinal tract environment containing high levels of neuroendocrine hormones is important for gut-derived P. aeruginosa infections. In this study, we report that the hormone norepinephrine increases P. aeruginosa PA14 growth, virulence factor production, invasion of HCT-8 epithelial cells, and swimming motility in a concentration-dependent manner. Transcriptome analysis of P. aeruginosa exposed to 500 µM, but not 50 µM, norepinephrine for 7 h showed that genes involved in the regulation of the virulence determinants pyocyanin, elastase, and Pseudomonas quinolone signal (PQS, 2-heptyl-3-hydroxy-4-quinolone) were up-regulated. The production of rhamnolipids, which are also important in P. aeruginosa infections, was significantly decreased on semi-solid surfaces, but not in planktonic cultures, upon exposure to norepinephrine. Swarming motility, a phenotype that is directly influenced by rhamnolipids, was also decreased upon 500 µM norepinephrine exposure. The increase in the transcriptional activation of lasR, but not that of rhlR, suggest that the effects of norepinephrine are mediated primarily through the las quorum sensing pathway. Together, our data strongly suggests that norepinephrine can play an important role in gut-derived infections by increasing the pathogenicity of P. aeruginosa PA14.

topA mutant of P. aeruginosa PA14

Project description:We have tested the effect of deletion of Topoisomerase I on genes transcription of the bacteria Pseudomonas. aeruginosa. Topoisomerase I is a conserved protein that modulate the topology state of the DNA from super-coiled to relaxed. To this end we have compared the transcription profile of a topA::GentR mutant to that of the wild-type strain. The topA mutant contains in topA gene a Mariner transposon with a gentamicin resistance cassette. It is part of the non-redundant mutant library of P. aeruginosa PA14 strains.
