Project description:Expression profiling of wild type E. coli K-12 strain MG1655 with exogenous glutathione (GSH) supplementation, sub-inhibitory ciprofloxacin concentration and GSH with inhibitory ciprofloxacin concentration. We used microarrays to detail the global gene expression program underlying ciprofloxacin exposure and glutathione mediated abrogation of ciprofloxacin's anti-bacterial action.
