The High Reactivity of Peroxiredoxin 2 with H2O2 Is Not Reflected in Its Reaction with Other Oxidants and Thiol Reagents*
Peroxiredoxin 2 is a member of the mammalian peroxiredoxin family of thiol proteins that is important in antioxidant defense and redox signaling. We have examined its reactivity with various… Expand

Insulin resistance is a cellular antioxidant defense mechanism
We know a great deal about the cellular response to starvation via AMPK, but less is known about the reaction to nutrient excess. Insulin resistance may be an appropriate response to nutrient excess,… Expand

Detection of reactive oxygen species derived from the family of NOX NADPH oxidases.
NADPH oxidases (NOX) are superoxide anion radical (O(2)(-•))-generating enzymes. They form a family of seven members, each with a specific tissue distribution. They function as electron transport… Expand

Superoxide-dependent Oxidation of Melatonin by Myeloperoxidase*
Myeloperoxidase uses hydrogen peroxide to oxidize numerous substrates to hypohalous acids or reactive free radicals. Here we show that neutrophils oxidize melatonin to… Expand

Novel fibrinogen γ375 Arg→Trp mutation (fibrinogen aguadilla) causes hepatic endoplasmic reticulum storage and hypofibrinogenemia
The proposita and her sister had chronically elevated liver function test results, and needle biopsy specimens showed scattered eosinophilic inclusions within the hepatocytes. On immunoperoxidase… Expand

Limited Role for the Bilirubin-Biliverdin Redox Amplification Cycle in the Cellular Antioxidant Protection by Biliverdin Reductase*
In mammalian cells, heme is degraded by heme oxygenase to biliverdin, which is then reduced to bilirubin by biliverdin reductase (BVR). Both bile pigments have reducing properties, and bilirubin is… Expand

Protection of erythrocytes by the macrophage synthesized antioxidant 7,8 dihydroneopterin
Neopterin and the reduced form, 7,8-dihydroneopterin (78NP), are pteridines released from macrophages when stimulated with γ-interferon in vivo. The role of 78NP in inflammatory response is unknown… Expand
