To compare the transcriptome of ompR null strains with wild-type strain of S. Typhimurium during osmotic stress

ABSTRACT: In bacteria, one paradigm for signal transduction is the two-component regulatory system, consisting of a sensor kinase (usually a membrane protein) and a response regulator (usually a membrane protein) and a response regulator (usually a DNA binding protein). The EnvZ/OmpR two-component system in S. Typhimurium responds to osmotic stress and regulates expression of outer membrane proteins. Furthermore, bacteria were believed to regulate pH by acidifying after external acid stress, then immediately recovering. Using a pH-sensor in single living cells, we show that S. Typhimurium maintain an acidic cytoplasm under sucrose-driven osmotic stress which requires OmpR. Thus, we set out to identify the OmpR targets of S. Typhimurium under osmotic stress.

To compare the transcriptome of ompR null strains with wild-type strain of E. coli during acid or osmotic stress

Project description:In bacteria, one paradigm for signal transduction is the two-component regulatory system, consisting of a sensor kinase (usually a membrane protein) and a response regulator (usually a membrane protein) and a response regulator (usually a DNA binding protein).

ChIP-on-chip of OmpR binding in Salmonella enterica serovar Typhimurium strain SL1344 and E.scherichia coli strain CSH50 at pH 7 and pH 4.5 including analysis of OmpR binding in SL1344 in the absence and presence of novobiocin (25 μg/ml)

Project description:OmpR is a DNA binding protein belonging to the OmpR/EnvZ two component system. This system is known to sense changes in osmolarity in Escherichia coli. Recently, OmpR in Salmonella enterica serovar Typhimurium was found to be activated by acidic pH and DNA relaxation. In this study, ChIP-on-chip was employed to ascertain the genome-wide distribution of OmpR in Salmonella Typhimurium and Escherichia coli in acidic and neutral pH. In addition we investigated the affect of DNA relaxation on OmpR binding in Salmonella Typhimurium. Analysis of OmpR binding at pH 7 and pH 4.5 in E-minimal medium in both SL1344 and CSH50. Three independent biological replicates at each pH 7 and pH 4.5 was performed. This was done in each strain background. DNA was immunopreciptated using an anti-FLAG anitbody which binds to flag-tagged OmpR in both strains. Two control M-bM-^@M-^XmockM-bM-^@M-^Y experiments were performed under the same culture condtions in each strain background; DNA was immunopreciptated using normal mouse IgG antibody. To analyse the effect of DNA relaxation onOmpR binding SL1344 was maintained in the exponential growth phase in LB broth with and without treatment with the drug novobiocin (25 M-NM-<g/ml) for 40 min. This was peformed on two independent occasions. In all cases the experimental immunoprecipitated DNA was hybridised against the input DNA.

Revealing the genome-scale transcriptional regulatory landscape of OmpR highlights its expanded regulatory roles and unexpected importance of narU under osmotic stress in Escherichia coli K-12 MG1655 [RNA-seq]

Project description:A transcription factor (TF), OmpR, plays a critical role in transcriptional regulation of the defense system for osmotic stress in bacteria. However, its full genome-wide regulatory potential is unknown. Here, we perform a genome-scale reconstruction of the OmpR regulon in Escherichia coli K-12 MG1655. Integrative data analysis reveals that a total of 37 genes in 24 transcription units (TUs) belong to OmpR regulon. Among them, 26 genes show more than two-fold changes in expression level under OmpR knock-out condition. We find that OmpR tends to regulate mostly membrane-located gene products of diverse fundamental biological processes, such as narU, ompX, and nuoN. Investigating co-regulation of entire set of genes regulated by other stress-response TFs unveils that they are surprisingly independently regulated by TF(s) responding to each stress. Additionally, detailed investigation of physiological roles of newly discovered OmpR regulon reveals that activation of narU encoding nitrate/nitrite transporter is a relatively unique strategy of E. coli K-12 MG1655 to significantly improve cellular tolerance toward osmotic stress.

Expression profiling by array of Salmonella enterica serovar Typhimurium (SL1344) qseC mutant x wild type

Project description:“Stress, survival and virulence: the multi-faceted host/microbial interactions.” Bacteria employ epinephrine and norepinephrine, which converge to distinct bacterial crucial processes, like survival and pathogenicity. A novel stress periplasmic membrane protein belonging to previously described BOF family, protein renamed here SrpP, and together with membrane sensor kinase QseC has an essential role in stress response and virulence of S. Typhimurium. SrpP employs its predicted binding pocket, specifically the SrpPE110 residue, and interacts with lipid A modification enzyme, LpxO dioxygenase. Upon this interaction SrpP in S. Typhimurium finely manages multiple membrane functions to culminate in survival upon stress and pathogenesis in vivo, connecting host-stress chemical signaling to cell stress in bacteria. Comparison of sensor histidine kinase qseC mutant expression levels versus wild type strain.

Reduction of Salmonella Typhimurium following exposure to multiple hurdle treatments of heated, acidified organic acid salt solutions occurs via membrane destabilization

Project description:The antimicrobial activity of organic acids in combination with non-chemical treatments was evaluated for inactivation of Salmonella Typhimurium. It was observed that the effectiveness of the multiple hurdle treatments were temperature and pH dependent and corresponded to the degree of organic acid lipophilicity. This led to the hypothesis that the loss in viability was due to cell membrane disruption. Evaluation of osmotic response, potassium ion leakage, and transmission electron micrographs confirmed effects on the cell membrane following treatment. Interestingly, all treatments, even those with no affect on viability, such as with sodium acetate, resulted in measurable cellular stress. Microarray experiments explored the specific response of S. Typhimurium to sodium acetate and sodium propionate, the most similar treatments in terms of pKa and ionic strength, and found little difference in the changes in gene expression following either treatment, despite their very different effects on viability. Taken together, the results reported support our hypothesis that following treatment with heated, acidified, organic acid salts, the loss of S. Typhimurium viability is at least in part due to membrane damage and the more lipophilic the organic acid the more effective the treatment. Overall, the data presented here indicate that a combined thermal, acidified sodium propionate treatment can provide a simple, yet effective antimicrobial treatment to combat Salmonella.
