Project description:Enterotoxigenic Escherichia coli (ETEC) is a globally prevalent cause of diarrhea. We report the first gene expression analysis of the human host response to experimental challenge with ETEC.
Project description:The purpose of this study is to determine whether the presence of pathogenic Escherichia coli in colon is associated with psychiatric disorders.
Project description:Despite the characterization of many aetiologic genetic changes. The specific causative factors in the development of sporadic colorectal cancer remain unclear. This study was performed to detect the possible role of Enteropathogenic Escherichia coli (EPEC) in developing colorectal carcinoma.
Project description:The experiment contains ChIP-seq data for Enterotoxigenic Escherichia coli strain H10407 transformed with plasmids pAMNF (encoding an N-terminal MarR-3xFLAG fusion) or pAMNM (encoding an N-terminal MarR-8xmyc fusion). The cells was cultured at 37 degrees in LB medium and crosslinked with 1 % (v/v) formaldehyde. After sonication, to break open cells and fragment DNA, immunoprecipitations were done using an anti-FLAG antibody (i.e. the strain encoding the MarR-8xmyc fusion was used as a control). Libraries were prepared using DNA remaining after immunoprecipitation.
Project description:The experiment contains ChIP-seq data for Enterotoxigenic Escherichia coli strain H10407 transformed with plasmid pRGM9818. The strain was grown at 37 degrees in LB medium and crosslinked with 1 % (v/v) formaldehyde. After sonication, to break open cells and fragment DNA, immunoprecipitations were done using antibodies against MarA, MarR or the RNA polymerase sigma 70 subunit. Libraries were prepared using DNA remaining after immunoprecipitation. Note that the MarR immunoprecipitations were not successful but the data served as a useful control for non-specifically immunoprecipitated DNA sequences.

Project description:To better understand the molecular effects of Enterotoxigenic Escherichia coli (ETEC) F4ab/ac infection, we performed a genome-wide comparison of the changes in DNA methylation in ETEC F4ab/ac infected porcine intestinal epithelial cells. Our data provides further insight into the epigenetic alterations of ETEC F4ab/ac infected porcine intestinal epithelial cells and may advance the identification of biomarkers and drug targets for predicting susceptibility to and controlling ETEC F4ab/ac induced diarrhea.
Project description:Enterotoxigenic Escherichia coli (ETEC) is a major cause of diarrhoea in children in resource-limited countries and of travellers diarrhoea. The ileal proteomics change after ETEC challenge is less characterised. Here in this study changes of ileal proteins post ETEC challenge in weaned pigs are studied. In total, 5151 ileal proteins were successfully annotated and 9 proteins had significantly different abundance between the ETEC and CON pigs.
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.
