The activities of two types of glutathione peroxidases (cGPx and PHGPx) were measured to estimate the availability of selenium for selenoprotein synthesis. Only sodium selenite between 1 and 100 nM was found to consistently induce GPx activity in all cell lines, whereas selenomethionine in equal concentrations was practically ineffective. Only THP-1 cells were able to utilize selenium from serum as efficiently as sodium selenite. PHGPx activity similarly responded to selenium supplementation, but was not increased in EL 4 6.1 cells. Our data demonstrate that conventional tissue culture media require selenium supplementation to guarantee adequate selenoprotein biosynthesis in cultured cells. The chemical nature of the selenium compound used for such supplement is as critical for in vitro cultivated cells as for dietary intake.</dcterms:abstract> <dc:contributor>Lotzer, K.</dc:contributor> <dc:rights>deposit-license</dc:rights> </rdf:Description> </rdf:RDF>
