Selenoprotein gene nomenclature [PDF]

open access: yes, 2016
The human genome contains 25 genes coding for selenocysteine-containing proteins (selenoproteins). These proteins are involved in a variety of functions, most notably redox homeostasis.

Effect of ochratoxin A and buthionine sulfoximine on proteome and ascorbate-glutathione cycle enzymes in Arabidopsis thaliana

open access: yesBiologia Plantarum, 2015
In this study, proteome and activities of glutathione (GSH)-related enzymes were investigated in detached leaves of Arabidopsis thaliana treated with ochratoxin A (OTA) alone or supplemented with buthionine sulfoximine (BSO, a specific inhibitor of the ...

Paradoxical roles of antioxidant enzymes:Basic mechanisms and health implications [PDF]

open access: yes, 2015
Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are generated from aerobic metabolism, as a result of accidental electron leakage as well as regulated enzymatic processes.

Prognostic significance of glutathione peroxidase 2 in gastric carcinoma

open access: yesTumor Biology, 2017
Increasing evidence suggests that the glutathione peroxidase 2 may actually play important roles in tumorigenesis and progression in various human cancers such as colorectal carcinomas and lung adenocarcinomas. However, the role of glutathione peroxidase

Selenium in biology: Facts and medical perspectives [PDF]

open access: yes, 2000
Several decades after the discovery of setenium as an essential trace element in vertebrates approximately 20 eukaryotic and more than 15 prokaryotic selenoproteins containing the 21(st) proteinogenic amino acid, selenocysteine, have been identified ...

Molecular responses of mouse macrophages to copper and copper oxide nanoparticles inferred from proteomic analyses [PDF]

open access: yesMol Cell Proteomics 12, 11 (2013) 3108-22, 2013
The molecular responses of macrophages to copper-based nanoparticles have been investigated via a combination of proteomic and biochemical approaches, using the RAW264.7 cell line as a model. Both metallic copper and copper oxide nanoparticles have been tested, with copper ion and zirconium oxide nanoparticles used as controls.

Aging-Related Decline of Glutathione Peroxidase 3 and Risk of Cardiovascular Events in Patients With Atrial Fibrillation [PDF]

open access: yes, 2016
BACKGROUND: Experimental studies demonstrated that glutathione peroxidase 3 (GPx3), an antioxidant enzyme that catabolizes hydrogen peroxide, protects against thrombosis. Little is known about its role in cardiovascular disease. METHODS AND RESULTS:

Association between polymorphisms in glutathione peroxidase and selenoprotein P genes, glutathione peroxidase activity, HRT use and breast cancer risk. [PDF]

open access: yesPLoS ONE, 2013
Breast cancer (BC) is one of the most common cancers in women. Evidence suggests that genetic variation in antioxidant enzymes could influence BC risk, but to date the relationship between selenoproteins and BC risk remains unclear.
