Peroxiredoxins (Prxs) constitute a major family of peroxidases, with mammalian cells expressing six Prx isoforms (PrxI to PrxVI). Cells produce hydrogen peroxide (HO) at various intracellular locations where it can serve as a signaling molecule. Given that Prxs are abundant and possess a structure that renders the cysteine (Cys) residue at the active site highly sensitive to oxidation by HO, the signaling function of this oxidant requires extensive and highly localized regulation.

Peroxiredoxin III and sulfiredoxin together protect mice from pyrazole-induced oxidative liver injury.

Antioxid Redox Signal 2012 Nov 31;17(10):1351-61. Epub 2012 May 31.

Division of Life and Pharmaceutical Sciences, Ewha Womans University, Seoul, Korea.

Aims: To define the mechanisms underlying pyrazole-induced oxidative stress and the protective role of peroxiredoxins (Prxs) and sulfiredoxin (Srx) against such stress.

Results: Pyrazole increased Srx expression in the liver of mice in a nuclear factor erythroid 2-related factor 2 (Nrf2)-dependent manner and induced Srx translocation from the cytosol to the endoplasmic reticulum (ER) and mitochondria. Pyrazole also induced the expression of CYP2E1, a primary reactive oxygen species (ROS) source for ethanol-induced liver injury, in ER and mitochondria. Read More

Peroxiredoxins in the central nervous system.

Subcell Biochem 2007 ;44:357-74

Asubio Pharma Co. Ltd. Research park, Institute of Integrated Medical Research Keio University, School of Medicine, Tokyo, Japan.

Oxidative stress is considered one of the causative pathomechanisms of nervous system diseases such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, stroke and excitotoxicity. The basal expression of six different peroxiredoxin (Prx) isozymes show distinct distribution profiles in different brain regions and different cell types. PrxI and VI are expressed in glial cells but not in neurons; while PrxII, III, IV and V are expressed in neurons. Read More

Mitochondrial peroxiredoxins.

Subcell Biochem 2007 ;44:295-315

Division of Biochemistry and Molecular Biology, Institute of Biomedical and Life Sciences, University of Glasgow, Glasgow, Scotland, UK.

Mitochondria are the major intracellular sites of oxygen consumption producing reactive oxygen species (ROS) as toxic by-products of oxidative phosphorylation, primarily via electron leakage from the respiratory chain. The resultant types of chemical damage to lipids, DNA and proteins are described as well as the broader implications for the involvement of ROS in disease onset and progression. The relative contributions of mitochondrial, enzyme-linked, antioxidant defence systems to tissue protection are also reviewed as is the emerging importance of the peroxiredoxin family in general to H2O2-mediated signalling The constituent enzymes of the mitochondrial PrxIII pathway are discussed in detail including the roles of PrxIII and PrxV in their capacities as typical 2-cys and atypical 2-cys thioredoxin-dependent hydroperoxide reductases, respectively.
