Project description:Expression profiling of wild type and purR deletion strains of E. coli K-12 MG1655 under both M9 minimal media and addition of adenine. An eight chip study with two different strains under two separate culture conditions.
Project description:Transcriptional profiling of E. coli MG1655 to Trimethoprim in i) LB media, ii) M9 minimal media and iii) M9 minimal media with supplements to study the association of gene expression with corresponding lethal and non-lethal growth conditions. Supplementation conditions in M9 media included addition of 50 microgram/ml of adenine, methionine, glycine or thymine in various combinations.
Project description:Transcriptional profiling of E. coli MG1655 to Trimethoprim in i) LB media, ii) M9 minimal media and iii) M9 minimal media with supplements to study the association of gene expression with corresponding lethal and non-lethal growth conditions. Supplementation conditions in M9 media included addition of 50 microgram/ml of adenine, methionine, glycine or thymine in various combinations. For all growth conditions, TMP was added to E. coli in mid-log phase and samples were taken at regular intervals from 10 minutes to 120 minutes post treatment. 1 Biological replicate per time point.
Project description:We integrated transcription factor binding regions and mRNA transcript abundance to elucidate the PurR regulon experimentally. To measure transcription factor binding at a genome scale, we employed a ChIP-chip method to derivative strains of E. coli K-12 MG1655 harboring PurR-8myc under various conditions.
Project description:The aim of this study is to investigate the changes of global gene expression in E. coli during a carbon source shift. Expression profiling of an evolved strain of E. coli K12 MG1655 grown in M9 minimal media supplemented with propylene glycol or glycerol.
Project description:Investigation of whole genome gene expression level in E. coli K-12 MG1655 in glucose M9 minimal media with/without heatshock A six chip study using total RNA recovered from E. coli K-12 MG1655 grown up to OD600nm 0.6 (mid-exponential phase) in M9 minimal media supplemented with 0.2% glucose with/without heatshock in 42oC. The high-density oligonucleotide tiling arrays used were consisted of 371,034 oligonucleotide probes with 50-bp length that are spaced 25 bp apart across the E. coli genome (NimbleGen). Experiments were performed with three biological replicates.
Project description:E. coli K-12 MG1655 was grown on M9 minimal media supplemented with 0.2% w/v glucose, fructose, or acetate. The goal of this study was to determine differentially expressed genes in the different media conditions.
Project description:RNA sequencing was performed on E. coli K12 MG1655 on three media (M9, CA-MHB, R10LB) treated with four antibiotics (Ciprofloxacin, Trimethoprim-sulfamethoxazole, Ceftriaxone, Meropenem) at their media-specific MIC90s

To measure transcription factor binding at a genome scale, we employed a ChIP-chip method to derivative strains of E. coli K-12 MG1655 harboring PurR-8myc under various conditions. A four ChIP-chip study under two separate culture conditions.
