Title Transcriptome reorganization of gene-rewired Escherichia coli cells in response to histidine depletion
Organism Escherichia coli
Experiment type Expression profiling by genome tiling array
Summary An assortment of genetically engineered Escherichia coli strains of the rewired gene regulation were used to study whether the cells could adapt to the environmental changes without the evolved gene regulatory machinaries. These E. coli strains had a synthetic gene circuit comprising a rewried gene that natively located within the His opeon. The cells growing under histidine supplied or depleted conditions were subjected to the macrioarray analysis. Multilevel analyses were performed to evaluate the global reorganization of gene expression in response to histidine depletion. A common pattern in transcriptome was observed in the adpative cells, indicating a survival strategy of "stochastic adaptation with regular transcriptome reorganization".
 
Overall design The genetically engineered strains of rewired genes and the control strain of the native gene regulation were grown in the presence and absence of histidine, and the cells within the exponetially growing phase were collected for the microarray analysis. Temproal changes in response to histidine depletion were also investigated. Every 3 biological replications for each condition were performed. Total 90 array assays were reported here.
