Cells grown to exponential phase (OD600 = 0.8) were harvested. Biological replicates, 3. Escherchia coli K12 oligonucleotide 3X15 K microarray (MYcroarray Inc. USA)
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:We successfully isolated an E. coli strain harboring rpoD mutant B8 with 2% (v/v) butanol tolerance using global transcriptional machinery engineering approach. DNA microarrays were employed to assess the transcriptome profile of n-butanol tolerance strain B8 and control strain E. coli JM109. The goal of this study is therefore to identify E. coli genes that are involved in n-butanol tolerance.
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.
