- Organotypic liver culture models: meeting current challenges in toxicity testingEdward L LeCluyse
The Institute for Chemical Safety Sciences, The Hamner Institutes for Health Sciences, Research Triangle Park, NC, USA
Crit Rev Toxicol 42:501-48. 2012..In the future, a balanced approach between sample throughput and biological relevance should provide better in vitro tools that are complementary with animal testing and assist in conducting more predictive human risk assessment...
- Xenobiotic-metabolizing enzyme and transporter gene expression in primary cultures of human hepatocytes modulated by ToxCast chemicalsDaniel M Rotroff
US Environmental Protection Agency, Office of Research and Development, National Center for Computational Toxicology, Research Triangle Park, North Carolina, USA
J Toxicol Environ Health B Crit Rev 13:329-46. 2010..Significant relative risk associations with rodent in vivo chronic toxicity effects are reported for the five major receptor pathways. These gene expression data are being incorporated into the larger ToxCast predictive modeling effort...

National Center for Computational Toxicology, Office of Research and Development, United States Environmental Protection Agency, Research Triangle Park, North Carolina 27711, USA
Toxicol Sci 117:348-58. 2010..Importantly, these tools are necessary to move beyond hazard rankings to estimates of possible in vivo responses based on in vitro screens...
- Human CYP2C8 is transcriptionally regulated by the nuclear receptors constitutive androstane receptor, pregnane X receptor, glucocorticoid receptor, and hepatic nuclear factor 4alphaStephen S Ferguson
Laboratory of Pharmacology and Chemistry, National Institute of Environmental Health Sciences, National Institutes of Health, Research Triangle Park, NC 27709, USA
Mol Pharmacol 68:747-57. 2005..In summary, the present studies show that CAR, PXR, GR, and HNF4alpha can regulate CYP2C8 expression and identify specific cis-elements within the promoter that control these regulatory pathways...
- Cross-species comparisons of transcriptomic alterations in human and rat primary hepatocytes exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxinMichael B Black
The Hamner Institutes for Health Sciences, Research Triangle Park, North Carolina 27709, USA
Toxicol Sci 127:199-215. 2012..The results provide evidence for divergent cross-species gene expression changes in response to TCDD and are consistent with epidemiological and clinical evidence showing humans to be less sensitive to TCDD-induced hepatotoxicity...
