We review signaling by reactive oxygen species, which is emerging as a major physiological process. However, among the reactive… Expand Dynamic analysis of redox-based processes in living cells is now restricted by the lack of appropriate redox biosensors… Expand The transcription factor NF-κB, a central regulator of immunity, is subject to regulation by redox changes. We now report that… Expand Reversible posttranslational modifications on specific amino acid residues can efficiently regulate protein functions. O… Expand The redox poise of the mitochondrial glutathione pool is central in the response of mitochondria to oxidative damage and redox… Expand Angiotensin II (AII) increases production of reactive oxygen species from NAD(P)H oxidase, a response that contributes to… Expand Oxidative stress broadly impacts cells, initiating regulatory pathways as well as apoptosis and necrosis. A key molecular event… Expand The OxyR transcription factor is sensitive to oxidation and activates the expression of antioxidant genes in response to hydrogen… Expand Stimulation of various cells with growth factors results in a transient increase in the intracellular concentration of H2O2 that… Expand E. coli B tsnC 7004, an E. coli B/1 mutant with normal phenotype unable to replicate phage T7 DNA [Chamberlin, M. (1974)J. Virol… Expand
