After these mice were injected with pro-oxidants paraquat or diquat at 12 to 125 mg/kg of body weight, their survival rate and time were a function of their GPX1 activity levels. The GPX1 protection was associated with attenuation of NADPH and NADH oxidation, protein carbonyl and F(2)-isoprostanes formation, and alanine transaminase release in various tissues, and was irreplaceable by high levels of dietary vitamin E or other selenoproteins. The GPX1 expression was also protective against moderate oxidative stress induced by low levels of paraquat or diquat, particularly in the Se-deficient mice. Alteration of GPX1 expression showed no impact on the expression of other selenoproteins and antioxidant enzymes in unstressed mice. Total Se content in liver of the Se-adequate GPX1(-/-) mice was reduced by 60% the WT controls. In conclusion, normal expression of GPX1 is essential and overexpression of GPX1 is beneficial to protect mice against acute oxidative stress."; prov:wasQuotedFrom pubmed:11568445 . sub:_5 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:11568445; prov:wasDerivedFrom beldoc:, sub:_4 . } sub:pubinfo { this: dcterms:created "2014-07-03T14:29:58.279+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
