The National Institute of Environmental Health Sciences (NIEHS)/National Toxicology Program (NTP) is accepting nominations of environmentally responsive genes and suggestions of criteria that could be used to prioritize these genes. The request for nominations was published in today’s Federal Register: the complete notice is available at: http://www.gpo.gov/fdsys/pkg/FR-2013-07-29/html/2013-18058.htm http://www.gpo.gov/fdsys/pkg/FR-2013-07-29/pdf/2013-18058.pdf NTP is planning to compile a comprehensive and prioritized list of environmentally responsive genes that might be targets for screening cell or tissues obtained from humans, rats, mice, zebrafish, and Caenorhabditis elegans against large numbers of substances. The goal is to generate a minimum list of 1000 genes for each species that would provide the maximal toxicogenomic information on (1) effects that reflect general cellular responses, independent of cell type or species, and (2) gene expression changes that are specific by organ and/or cell type. Nominated genes and/or recommendations on prioritization criteria should be submitted electronically in Microsoft Excel or Word formats to Genelist@xxxxxxxxxxxxx<mailto:Genelist@xxxxxxxxxxxxx>. The submission deadline is August 23, 2013. For more information, please contact Dr. Elizabeth Maull at maull@xxxxxxxxxxxxx<mailto:maull@xxxxxxxxxxxxx>.
