Project description:Cellular tolerance toward ethanol is a complex phenotype involved many genes, and hard to be improved by manipulating individual genes. We previously established exogenous global regulator IrrE mutants that confer Escherichia coli with significantly enhanced tolerance to stresses, including ethanol. In order to elucidate the mechanism for enhancement of ethanol tolerance in the mutants and to identify new genes and pathways that can be possible targets for engineering of ethanol tolerance, we carried out comparative transcriptomic and proteomic analyses with the representative strains E1 and E0 (harboring the ethanol-tolerant mutant E1 of IrrE and the wild type IrrE, respectively). The data from transcriptome analyses were deposited here.

The data from transcriptome analyses were deposited here. Cells of ethanol-tolerant mutant E1 and wild-type strain E0 were grown in 1.5% ethanol, and the samples for both of these two strains were prepared in triplicate with biological replicates
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:The goal of this experiment is to identify the pathways that are deregulated as part of an adaptive response to high levels of ethanol in the media. Ethanol tolerant cells (HG228) grown in minimal media plus 1.5% (v/v) ethanol were hybridized against E. coli MG1655 grown under similar conditions. The experiment was done in duplicates using biological replicates.
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:To understand the mechanism of isopropanol tolerance of Escherichia coli for improvement of isopropanol production, we performed genome re-sequencing and transcriptome analysis of isopropanol tolerant E. coli strains obtained from parallel adaptive laboratory evolution under IPA stress.
Project description:In order to understand the impact of genetic variants on transcription and ultimately in changes in observed phenotypes we have measured transcript levels in an Escherichia coli strains collection, for which genetic and phenotypic data has also been measured.
Project description:To investigate the regulatory targets of the RegR virulence regulon of rabbit specific enteropathogenic Escherichia coli strain E22
