TranscriptomicsChIP-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 M-NM-
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 wa...

TranscriptomicsTranscription profiling of E. coli W3110 wild type and rpoZ mutant cells to distinguish between the genes expressed either in the presence or absence of RNA polymerase omega subunit during log phase
Comparison of transcript profiles of E. coli W3110 wild-type and rpoZ mutant cells to distinguish between the genes expressed either in the presence or absence of RNA polymerase omega subunit during log phase. Comparison of transcript profiles of E. coli rpoZ mutant cells with or without overproduct...

Transcriptomics14028s araC RNA-Seq
We used RNA-seq to determine the effects of AraC and arabinose on RNA levels genome-wide in S. enterica. Wild-type or delta araC mutant cells were grown in both the presence and absence of 0.2% L-arabinose. RNA-Seq libraries from two independent biological replicate samples were sequenced for (i) wi...

MetabolomicsUltra-High Mass Resolving Power, Mass Accuracy, and Dynamic Range MALDI Mass Spectrometry Imaging by 21-T FT-ICR MS

Detailed characterization of complex biological surfaces by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) requires instrumentation that is capable of high mass resolving power, mass accuracy and dynamic range. Fourier transform ion cyclotron resonance mass sp...

TranscriptomicsEffect of NaCl concentration on the transcriptional network of E. coli in glucose minimal medium with glycine betaine
The growth rate of E. coli decrease continuously with NaCl concentration, however the pattern for metabolic efficiency as measured by optical density is corralated to a change in pattern in transcription data and proteomics.The analysis of the data suggest that between 4.5 and 5% NaCl, the metaboli...

TranscriptomicsTranscription profiling by array of E. coli NCTC 9001 challenged with four different cationic antimicrobial peptides
Obtaining an in depth understanding of the arms races between peptides comprising the innate immune response and bacterial pathogens is of fundamental interest and will inform the development of new antibacterial therapeutics. Many cationic antimicrobial peptides (AMPs) share a range of structural a...

TranscriptomicsImpact of intramammary treatment on gene expression profiles of bovine mammary gland tissue after challenge with E. coli
The benefit of treatment in mild to moderate cases of E. coli mastitis in dairy cows remains a topic of discussion. We investigated the effect of intramammary treatment with Cefapirin + Prednisolone compared to Cefapirin only on gene expression profiles in experimentally induced E. coli mastitis. Fi...
