Title Transcriptional profiling of Escherichia coli after addition of CORM-3 and iCORM-3 to aerobically and anaerobically growing cells
Organism Escherichia coli
Experiment type Expression profiling by array
Summary Escherichia coli strain MG1655 was grown in a New Brunswick Scientific Bioflow III Biofermentor under continuous culture (chemostat) conditions. Cells were grown in defined media containing 2 mM glycerol as the sole and limiting source of energy and carbon. The working volume was 200 ml, and the dilution rate 0.2 h-1. For aerobic growth, the air-flow rate was 0.1 l/min, and the dissolved oxygen tension was maintained at ~7% air saturation by measuring oxygen dissolved in the culture using a Broadley James D140 OxyProbe® electrode. For anaerobic growth, cells are grown on 100 % nitrogen gas bubbled at 0.1 l/min Cells were grown as above to steady-state, At steady-state, CORM-3 or iCORM-3 was added to the chemostat culture at a final concentration of 40 uM.
Samples were taken immediately prior to the addition of CORM-3 or iCORM-3 and over a time course of 2.5, 5, 10, 20, 40 and 80 min exposure to (i)CORM-3 for subsequent analysis using microarrays. Cells were harvested directly into phenol:ethanol to stabilize RNA, and total RNA was purified using Qiagen’s RNeasy Mini kit as recommended by the suppliers.
Overall design Time course experiment with samples taken immediately prior to or 2.5, 5, 10, 20, 40 or 80 minutes after addition of either 40uM CORM-3 or iCORM-3 under either 0 or 100 % perceived aerobiosis. 2 biological repeats were performed for each condition with 2 technical (dye swap) repeats per biological repeat.
