Project description:Here, we investigated the impact of Stx2 phage carriage on Escherichia coli (E. coli) K-12 MG1655 host gene expression. Using quantitative RNA-seq analysis, we compared the transcriptome of naïve MG1655 and the lysogens carrying the Stx2 phage of the 2011 E. coli O104:H4 outbreak strain or of the E. coli O157:H7 strain PA8, which share high degree of sequence similarity.
Project description:To investigate and compare transcriptomic changes of Escherichia coli K-12 MG1655, the bacterium was exposed to nine antibiotics (tetracycline, mitomycin C ,imipenem, ceftazidime, kanamycin, ciprofloxacin, polymyxin E, erythromycin, and chloramphenicol) , and RNA-Seq was performed to determine comparative transcriptomic changes.
Project description:Sequencing reads of Escherichia coli K-12 control and antibiotic-treated cultures enriched (Cappable-Seq) and not enriched (Ultra directional) for the 5’ end of primary transcripts.
Project description:Investigation of whole genome gene expression level changes in a Escherichia coli MG1655 K-12 ∆arcA mutant, compared to the wild-type strain. The mutations engineered into this strain produce a strain lacking the ArcA protein. The results are further described in the manuscript The response regulator ArcA uses a diverse binding site architechture to globally regulate carbon oxidation in E. coli
Project description:Investigation of whole genome gene expression level changes in a Escherichia coli MG1655 K-12 ?fnr mutant, compared to the wild-type strain. The mutations engineered into this strain produce a strain lacking the FNR protein. WT strains were grown under aerobic and anaerobic growth conditions.
Project description:Escherichia coli (E. coli) amine oxidase (ECAO) encoded by tynA gene has been one of the model enzymes to study the mechanism of oxidative deamination of amines to the corresponding aldehydes by amine oxidases. The biological roles of ECAO have been less addressed. Therefore we have constructed a gene deletion Escherichia coli K-12 strain, E. coli tynA-, and used the microarray technique to address its function by comparing the total RNA gene expression to the one of the wt. Our results suggest that tynA is a reserve gene for stringent environmental conditions and its gene product ECAO a growth advantage compared to other bacteria due to H2O2 production.
Project description:Investigation of whole genome gene expression level changes in a Escherichia coli MG1655 K-12 M-bM-^HM-^FarcA mutant, compared to the wild-type strain. The mutations engineered into this strain produce a strain lacking the ArcA protein. The results are further described in the manuscript The response regulator ArcA uses a diverse binding site architechture to globally regulate carbon oxidation in E. coli A six chip study using total RNA recovered from three separate cultures of Escherichia coli MG1655 K-12 WT and three separate cultures of the M-bM-^HM-^FarcA mutant strain. Each chip measures the expression level of 4,661 genes from Escherichia coli MG1655 K-12 with eight 60-mer probes per gene, with each probe represented twice on the array.

A six chip study using total RNA recovered from two separate cultures of Escherichia coli MG1655 K-12 WT (aerobic and anaerobic) and two separate cultures of the ?fnr mutant strain (anaerobic). Each chip measures the expression level of 4,661 genes from Escherichia coli MG1655 K-12 with eight 60-mer probes per gene, with each probe represented twice on the array.
Project description:The purpose of this study is to determine whether the presence of pathogenic Escherichia coli in colon is associated with psychiatric disorders.
