Mouse Liver Tumor Mode of Action: Use of Toxicogenomics in Weight of Evidence for Human Relevance Assessment
ABSTRACT The Use of Toxicogenomics in Chemical Safety Testing Current safety testing is geared to produce and accept descriptive data from high-dose animal studies Interpretation of this information has effectively protected our health and safety for decates; however, hindered by lack of understanding mechanistic information Concern over chemical safety for humans and the environment hasRead More
Species Differences in Pregnane X Receptor Activation: Examination of common laboratory animal species
ABSTRACT Nuclear receptors (NRs) are ligand-dependent transcription factors found in many species that regulate the expression of important target genes involved in a spectrum of developmental and physiological processes. The ligand binding domain (LBD) of NRs is responsible for both ligand recognition and regulation of protein-protein interactions, notably with coregulatory factors. NRs represent important targetsRead More

Evidence for triclosan-induced activation of human and rodent xenobiotic nuclear receptors
ABSTRACT The bacteriostat triclosan (2,4,4′-trichloro-2′-hydroxydiphenylether) (TCS) decreases rat serum thyroxine via putative nuclear receptor (NR) interaction(s) and subsequent transcriptional up-regulation of hepatic catabolism and clearance. However, due to the evolutionary divergence of the constitutive androstane and pregnane-X receptors (CAR, PXR), TCS-mediated downstream effects may be species-dependent. To test the hypothesis that TCS activates xenobiotic NRsRead More
