Adaptive response of Schizosaccharomyces pombe to hydrogen peroxide and menadione.
The response of Schizosaccharomyces pombe to oxidative stresses has been examined. On challenging Schiz. pombe for 60 min at early exponential phase with either 40 mM H2O2 or 6 mM menadione (MD), a superoxide-generating agent, less than 10% of the cells survived. Pretreating Schiz. pombe cells with 0.2 mM H2O2 or 0.2 mM MD for 1 h significantly increased survival of these lethal doses of each o...
متن کاملImportance of catalase in the adaptive response to hydrogen peroxide: analysis of acatalasaemic Saccharomyces cerevisiae.
Controversy about the importance of catalase in the detoxification of H2O2 in human erythrocytes continues. It has been suggested that catalase has no role in the clearance of H2O2 in erythrocytes. In the present study we investigated the role of catalase in the defence mechanism against oxidative stress using Saccharomyces cerevisiae. S. cerevisiae has two catalases, catalase A and catalase T....
متن کاملImportance of glucose-6-phosphate dehydrogenase in the adaptive response to hydrogen peroxide in Saccharomyces cerevisiae.
Glucose-6-phosphate dehydrogenase (G6PDH)-deficient cells of Saccharomyces cerevisiae showed increased susceptibility and were unable to induce adaptation to oxidative stress. Historically, mainly in human erythrocytes, it has been suggested and accepted that decreased cellular GSH, due to loss of the NADPH-dependent activity of glutathione reductase (GR), is responsible for the increased sensi...
متن کاملHydrogen peroxide mediates plant root cell response to nutrient deprivation.
Potassium (K(+)) is an essential nutrient required by plants in large quantities, but changes in soil concentrations may limit K(+) acquisition by roots. It is not known how plant root cells sense or signal the changes that occur after the onset of K(+) deficiency. Changes in the kinetics of Rb(+) uptake in Arabidopsis roots occur within 6 h after K(+) deprivation. Reactive oxygen species (ROS)...
متن کاملGlobal transcriptome analysis of Staphylococcus aureus response to hydrogen peroxide.
Staphylococcus aureus responds with protective strategies against phagocyte-derived reactive oxidants to infect humans. Herein, we report the transcriptome analysis of the cellular response of S. aureus to hydrogen peroxide-induced oxidative stress. The data indicate that the oxidative response includes the induction of genes involved in virulence, DNA repair, and notably, anaerobic metabolism.
