MetabolomicsHfq Regulates Efflux Pump Expression and Purine Metabolic Pathway to Increase the Trimethoprim Resistance in Aeromonas veronii

Aeromonas veronii (A. veronii) is a zoonotic pathogen. It causes clinically a variety of diseases such as dysentery, bacteremia, and meningitis. And it also brings huge losses to aquaculture. A. veronii has been documented as a multiple antibiotic resistant bacterium. Hfq (host factor for RNA bac...

TranscriptomicsHfq-coIP overgrowth
The small RNAs associated with protein Hfq constitute one of the largest classes of post-transcriptional regulators known to date. Most previously investigated members of this class are encoded by conserved free-standing genes. Here, deep sequencing of Hfq-bound transcripts from multiple stages of g...

TranscriptomicsKlebsiella pneumoniae: WT vs. Hfq mutant
Transcriptional profiling of K. pneumoniae comparing the wild type strain (S5) with a hfq deletion mutant (H0201). Goal was to determine the effects of Hfq absence on global K. pneumoniae gene expression. WT vs. Hfq mutant. Eight replicates for each ORF presented in the 44K array.

ProteomicsHfq is involved in global protein expression and stress response in Bordetella pertussis
In this study, we used gel-free nanoLC-MS/MS-based proteomics to compare the protein profile of B. pertussis wild type and an isogenic hfq defective mutant strain under control an iron limited conditions. We found that Hfq affects the abundance of 302 proteins, which represents 8% of the total B. pe...

TranscriptomicsComparison of the expression profiles of 630E strain and a hfQ mutant after 7.5h of growth in Tyt
Clostridium difficile is an emergent human pathogen and the most common cause of nosocomial diarrhea. Our recent deep-sequencing data strongly suggest the importance of RNA-based mechanisms for the control of gene expression in C. difficile. The RNA chaperon protein Hfq is a key component of post-tr...

TranscriptomicsComparison of the expression profiles of 630E strain and an Hfq antisense after 7.5h of growth in Tyt
Transcriptional profiling of C. difficile 630E strain vs. an Hfq antisense after 7.5h of growth inTYt. Two-conditions experiments, 630E strain vs. Hfq antisense grown in TYt, 4 biological replicates for each condition.

TranscriptomicsFunctional characterization of the RNA chaperone Hfq in opportunistic human pathogen Stenotrophomonas maltophilia
Stenotrophomonas maltophilia is an important opportunistic pathogen affecting primarily hospitalized and immuno-compromised hosts. We constructed an hfq deletion mutant (Delta-hfq) of S. maltophilia, and compared the behaviour of wild-type and Delta-hfq S. maltophilia cells in a variety of assays. D...

TranscriptomicsTracking the elusive function of Bacillus subtilis Hfq (NimbleGen)
Transcriptomic analysis of Bacillus subtilis hfq mutant in exponential phase of growth. Wild-type strain and hfq mutant cells in exponentially growth phase were subjected to tiling array gene expression analysis. RNA-binding protein Hfq is a key component of the adaptive responses of many proteobact...

TranscriptomicsExpression data from wildtype Sinorhizobium meliloti Rm1021 and an hfq mutant
The RNA-binding protein Hfq is a global regulator, which controls diverse cellular processes in bacteria. To begin understanding the role of Hfq in the Sinorhizobium meliloti-Medicago truncatula nitrogen-fixing symbiosis, we defined free-living and symbiotic phenotypes of an hfq mutant. Over 500 tra...
