However, only few tools to address this topic are available. The aim of this study was to develop a neurotoxicity/developmental neurotoxicity (DNT) test system, using the pluripotent mouse embryonic stem cell line CGR8 (ESCs). The test system uses ESCs at two differentiation stages: undifferentiated ESCs and ESC-derived neurons. Under each condition, concentration-response curves were obtained for three parameters: activity of the tubulin alpha 1 promoter (typically activated in early neurons), activity of the elongation factor 1 alpha promoter (active in all cells), and total DNA content (proportional to the number of surviving cells). We tested 37 compounds from the ESNATS test battery, which includes polypeptide hormones, environmental pollutants (including methylmercury), and clinically used drugs (including valproic acid and tyrosine kinase inhibitors). Different classes of compounds showed distinct concentration-response profiles. Plotting of the lowest observed adverse effect concentrations (LOAEL) of the neuronal promoter activity against the general promoter activity or against cytotoxicity, allowed the differentiation between neurotoxic/DNT substances and non-neurotoxic controls. Reporter activity responses in neurons were more susceptible to neurotoxic compounds than the reporter activities in ESCs from which they were derived. To relate the effective/toxic concentrations found in our study to relevant in vivo concentrations, we used a reverse pharmacokinetic modeling approach for three exemplary compounds (teriflunomide, geldanamycin, abiraterone). The dual luminescence reporter assay described in this study allows high-throughput, and should be particularly useful for the prioritization of the neurotoxic potential of a large number of compounds.</dcterms:abstract> <dc:creator>Ilmjärv, Sten</dc:creator> <dc:creator>Peterson, Hedi</dc:creator> <dc:creator>Julien, Stephanie</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2016-05-20T08:09:27Z</dc:date> <dcterms:rights rdf:resource="http://nbn-resolving.de/urn:nbn:de:bsz:352-20150914100631302-4485392-8"/> <dc:creator>Colaianna, Marilena</dc:creator> <dc:creator>Kern, Ilse</dc:creator> <dc:creator>Pallocca, Giorgia</dc:creator> <dc:creator>Bosgra, Sieto</dc:creator> <dc:language>eng</dc:language> <dc:contributor>Baquié, Mathurin</dc:contributor> <dc:contributor>Leist, Marcel</dc:contributor> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/34011"/> <dc:contributor>Kern, Ilse</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2016-05-20T08:09:27Z</dcterms:available> <dc:contributor>Colaianna, Marilena</dc:contributor> <dc:contributor>Julien, Stephanie</dc:contributor> <dc:contributor>Pallocca, Giorgia</dc:contributor> </rdf:Description> </rdf:RDF>
