Whole transcriptome sequencing of E. coli BW25113 wt and nudC knockout strains

Project description:In the present study we performed total RNA sequencing of E. coli BW25113 wt and nudC knockout strains. RNA-seq analysis revealed that the inactivation of nudC gene in bacteria shows alteration of level of sRNA and protein-coding transcripts mainly associated with bacterial chemotaxis and flagellar assembly pathways.

BW25113 H202 and delta rpoS persister cells vs. stationary phase BW25113 wild-type

Project description:E. coli K-12 BW25113 persister cells generated via H202 pre-treatment and deletion of rpoS, relative to BW25113 wild-type stationary phase gene expression. Persister cells were generated following exposure to ampicillin 20 ug/mL. Strains: BW25113 wild-type, pre-treated with H202 10 min, ampicillin 5 h; BW25113 delta rpoS, ampicillin 5 h; BW25113 wild-type OD at 600 nm of 3.0, ampicillin 30 mins. Medium: LB ampicillin 20 ug/mL used to generate persisters; ampicillin 5 ug/mL added to stationary phase BW25113 wild-type

5’-NAD-RNA identification in E. coli BW25113 wt, nudC and csdA knockouts

Project description:In the present study we applied NAD captureSeq to charecterize the 5'-NAD-RNA profile of E. coli BW25113 wt strain as well as nudC and csdA knockouts. The data obtained showed that both knockouts resulted in an increased number of identified 5’-NAD-RNA species, thus suggesting that CsdA might add a potentially new layer of control on NAD-epitranscriptomic landscape.

Transcriptional responses of Escherichia coli rpoS- BW25113 vs. wild-type BW25113 under 15% ethanol shock in log phase

Project description:RpoS, an alternative sigma factor, is critical for stress response in Escherichia coli.RpoS also acts as a global regulator for stress control of gene expression, and actually dose so in log stage and stationary stage. To further understand the effect of environmental stresses on in ethanologenic strains, DNA microarrys was used to analyze the expression profiles of E. coli and its rpoS mutant strain. BW25113（rpoS-）and BW25113 were selected at log stages and stationary stage of early development for RNA extraction and hybridization on Affymetrix microarrays. To that end, we hand-selected BW25113 and BW25113（rpoS-） according at different treatments: BW25113（rpoS-）at log stage (BW25113(rpoS-) log), BW25113 at log stage (BW25113 log),BW25113（rpoS-）atstationary stage ( BW25113(rpoS-) stationary), BW25113 at stationary stage ( BW25113 stationary)

Transcriptome RNA Sequencing Data Set of Differential Gene Expression in Escherichia Coli BW25113 SlyA Wild Type and Mutant Strains

Project description:Escherichia coli laboratory strains remain instrumental to the discovery and development of biomarkers as drugs and diagnostic analytes in the post genomic era. The transcriptional regulator SlyA is a member of the multiple antibiotic resistance regulator family of transcription factors, which is associated with bacterial responses to host-derived oxidative stress, antibiotics resistance and virulence, and homologues exist in other Enterobacteriaceae. Here, we announce a transcriptome RNA sequencing data set detailing global gene expression in the wild type E. coli BW25113 and the slyA mutant. Results reveal heterogeneous functionality of SlyA that may vary between pathovars of E. coli. but which require further annotations of differentially expressed tRNAs

Transcription profiling of E. coli K-12 BW25113 wt and E. coli K-12 BW25113 yjgK deleted mutant on 8 h biofilm cell development

Project description:The role of six toxin-antitoxin (TA) systems on biofilm development was investigated (MazEF, RelBEF, ChpB, YefM-YoeB, DinJ-YafQ, and TomB-Hha). Although these TA systems were reported previously to not impact bacterial fitness, we found that biofilm formation is decreased by toxins and increased by anti-toxins, in part, through YjgK. Hence, one role of TA systems is to regulate biofilm formation. Experiment Overall Design: Strains: E. coli K-12 BW25113 wild-type and E. coli BW25113 yjgK deleted mutant Experiment Overall Design: Medium: LB Experiment Overall Design: Cells: biofilm cells on glass wool Experiment Overall Design: Time: 8 h Experiment Overall Design: Temperature: 37oC
