OBJECTIVE
The Acute Respiratory Distress Syndrome (ARDS), the most severe form of Acute Lung Injury (ALI), is a highly-fatal, diffuse non-cardiogenic edematous lung disorder. The pathogenesis of ARDS is unknown but lung inflammation and lung oxidative stress are likely contributing factors. Since no
Myeloperoxidase (MPO)-generated halogenating molecules, such as hypochlorous acid and hypobromous acid (HOBr), in inflammatory regions are postulated to contribute to disease progression. In this study, we showed that ergothioneine (EGT), derived from an edible mushroom, inhibited MPO activity as
The above article from Clinical and Experimental Pharmacology and Physiology, published as an Accepted Article online on 10 February 2015 in Wiley Online Library (http://wileyonlinelibrary.com), has been retracted by agreement between the authors, the Journal Editor-in-Chief, Jun-Ping Liu, and John
OCTN1/SLC22A4 is expressed on apical membranes of small intestine, and is involved in gastrointestinal absorption of its substrates, including the food-derived antioxidant ergothioneine (ERGO). ERGO concentration in circulating blood of patients with inflammatory bowel disease (Crohn's disease) is
Inflammation and reactive oxygen species have been implicated in pathogenesis of vascular diabetic complications. However, treatment with classic free-radical scavengers and antioxidants has not been yet proved to reduce the risk of developing such complications. In search of more effective
BACKGROUND
Ergothioneine (ET) is a sulfur containing amino acid that functions as an antioxidant. Mushrooms are a primary source of ET containing from 0.4 to 2.0mg/g (dry-weight). The bioavailability of ET from mushrooms in humans remains unclear.
OBJECTIVE
We evaluated the bioavailability of ET in
We investigated the uptake and pharmacokinetics of l-ergothioneine (ET), a dietary thione with free radical scavenging and cytoprotective capabilities, after oral administration to humans, and its effect on biomarkers of oxidative damage and inflammation.
After oral administration, ET is avidly
L-(+)-ergothioneine has antioxidant and anti-inflammatory properties in vitro and in vivo and has uses as a dietary supplement and as an ingredient in foods, cosmetics, and as a pharmaceutical additive. The clastogenic potential and mutagenic of ergothioneine were assessed in vitro and in vivo.
Oxidants and inflammatory mediators such as tumour necrosis factor-alpha (TNF-alpha) activate transcription factors such as NF-kappa B. Interleukin-8 (IL-8) is a ubiquitous inflammatory chemokine that mediates a multitude of inflammatory events in the lung. Ergothioneine is a naturally occurring
Ergothioneine is a natural 2-thiol-amidazole amino acid that plays an important role in inflammation, depression, and cardiovascular disease. Flammulina velutipes is a common basidiomycete mushroom rich in ergothioneine (EGT). However, the biosynthetic pathway of EGT in F. velutipes is still
L-ergothioneine levels were measured in amniotic fluid of pregnant sheep after natural mating and transfer of vitrified/thawed in-vitro produced embryos. Amniotic fluids were collected between 60 and 65 and 80-85 days of gestation and analysed by an ultra-performance liquid chromatographic
OBJECTIVE
To evaluate anti-inflammatory properties of a nutraceutical blend containing L-ergothioneine in concert with other anti-inflammatory and analgesic ingredients, combined with nutritional cartilage support.
METHODS
Twelve human subjects were tested over a 6-week period of product consumption
The shiitake (Lentinus edodes) extract is purported to have potent antioxidant, anti-inflammatory and regenerative properties due to presence of many bioactive compounds such as ergothioneine. This study was designed to assess the antioxidant and anti-inflammatory activity of shiitake extract in
OBJECTIVE
The dietary thiol compound and erythrocyte ingredient ergothioneine (ET) is the preferential physiological substrate of the organic cation transporter OCTN1, found to be associated with rheumatoid arthritis (RA) in genetic studies, but the biological roles of ET and OCTN1 are unclear. We
Ergothioneine (EGT) is a sulfur-containing amino acid, and is presumed to function as a natural antioxidant. The purpose of this study was to identify the nature of the antioxidant activity and investigate the effects of EGT on UV-induced cellular response. In chemical studies, EGT scavenged the
