Schematic representation of the approach followed to evaluate the predictive potential of catalase activity as a biomarker for mild-stress-induced robustness. The induction of catalase activity () was quantified upon mild-stress treatment. Also, cells were exposed to conditions of mild stress and subsequently exposed to severe stress to quantify the robustness enhancement elicited by mild-stress pretreatment. To evaluate whether the catalase activity could function as a biomarker for mild-stress-induced robustness, the induction of catalase activity upon mild-stress treatment was correlated to mild-stress-induced robustness, and this correlation was tested for significance (Adapted from reference 15 [published by BioMed Central].)
