OTUD6A‐Mediated Deubiquitination of PRDX1 Protects Against Oral Ulcer by Restoring Mitochondrial Function

Advanced Science, EarlyView.
In human oral keratinocytes, OTUD6A promoted cell migration by deubiquitinating and stabilizing PRDX1. Conversely, OTUD6A deficiency reduced PRDX1 stability, triggering mitochondrial dysfunction and aggravating OU progression. ABSTRACT Oral ulcers (OU), as the most highly prevalent and recurrent oral mucosal lesion, have an unclear pathogenesis that ...

A primer on peroxiredoxin biochemistry [PDF]

Free Radical Biology and Medicine, 2015
Peroxiredoxins were not recognized as a family of enzymes until the 1990s but are now known to be the dominant peroxidases in most organisms. Here, the history and fundamental properties of peroxiredoxins are briefly reviewed, with a special focus on describing how an exquisitely tunable balance between fully folded and locally unfolded conformations ...

Spatial Cell Death and Oxidative Stress Dynamics in Gas Plasma‐Treated Tumor Tissues

Advanced NanoBiomed Research, EarlyView.
Schematic representation of the four experimental models to study tissue penetration and oxidation. Four tissue models were used. Human pancreatic cancer cells were grown on the chorioallantois membrane of chicken embryos and gas plasma‐treated in ovo, murine colorectal tumor tissue was gas plasma‐exposed ex vivo, murine squamous cell carcinoma cells ...

Spectroscopic and In Silico Determination of the Structural and Antioxidant Properties of Essential Oils From Lavandula Species Cultivated in the Silivri Region of Istanbul

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Plants are important sources of bioactive compounds that contribute to nutrition, health maintenance, and disease prevention. In this study, the chemical composition and antioxidant potential of essential oils obtained from Lavandula angustifolia “Sevtopolis” and Lavandula × intermedia cultivated in the Silivri region of Istanbul were ...

Mitochondrial peroxiredoxin 3 is more resilient to hyperoxidation than cytoplasmic peroxiredoxins [PDF]

Biochemical Journal, 2009
The Prxs (peroxiredoxins) are a family of cysteine-dependent peroxidases that decompose hydrogen peroxide. Prxs become hyperoxidized when a sulfenic acid formed during the catalytic cycle reacts with hydrogen peroxide. In the present study, Western blot methodology was developed to quantify hyperoxidation of individual 2-Cys Prxs in cells.

Peroxiredoxin 6 as a Unique Member of the Peroxiredoxin Family [PDF]

, 2019
The peroxiredoxin family was discovered approximately 30 years ago and is now recognized as one of the most important families of enzymes related to antioxidant defense and cellular signaling. Peroxiredoxin 6 shares the basic enzymatic functions that characterize this family, but also exhibits several unique and crucial activities.

Localized redox relays as a privileged mode of cytoplasmic hydrogen peroxide signaling

Redox Biology, 2017
Hydrogen peroxide (H2O2) is a key signaling agent. Its best characterized signaling actions in mammalian cells involve the early oxidation of thiols in cytoplasmic phosphatases, kinases and transcription factors.
