BACKGROUND The mucosal pathology of Helicobacter pylori infection may in part be due to excessive production of reactive oxygen metabolites (ROMs) by phagocytes. The influence of H pylori infection on mucosal superoxide dismutases, some major scavenger enzymes of ROM was investigated. In humans superoxidase dismutase is present in at least two forms-that is, mitochondrial manganese (Mn)-superox...
Mutations in RAS2, CYR1, and SCH9 extend the chronological life span in Saccharomyces cerevisiae by activating stress-resistance transcription factors and mitochondrial superoxide dismutase (Sod2). Here we show that mutations in CYR1 and SCH9 also extend the replicative life span of individual yeast mother cells. However, the triple deletion of stress-resistance genes MSN2/MSN4 and RIM15, which...
