Assessment of Oxidative Stress Response (OxStrR) Biomarkers. (A-B) Examples of bright field and fluorescence images of C. elegans carrying an integrated transgene with the promoter for phase II enzyme gst-4 fused to GFP to monitor OxStrR. (C-F) Biosensor fold-change relative to water control, from at least three independent experiments per exposure group. Top concentrations shown are maximum concentration not altering adult size and optical density below 80% of control. Error bars: standard error of the mean (SEM), T-test p-values *<0.05, ** <0.005.
