McLean 2010Peroxynitrite toxicity; Oxidative stressE. coli K-12 (MG1655)MWG E. coli K12 ArrayPeroxynitrite was added directly to growing cultures in log phase which triggered an up-regulation of oxidative stress response genes. Transcriptomic analysis of cells treated with hydrogen peroxide alone also revealed up-regulation of oxidative stress response genes but not of many other genes that are up-regulated by peroxynitrite. The authors show that the cellular responses to peroxynitrite and hydrogen peroxide are distinct. Samantha McLean

The experiment was carried out in triplicate and a dye swap was performed for each.
