(Submitter supplied) Liver gene transcripts patterns were used to characterize toxicity from exposure to polybrominated diphenyl ethers (PBDEs), flame retardant components. In this study, Wistar Han dams were exposed by gavage to the PBDE mixture (DE71) starting at gestation day 6 (GD 6) and continuing to weaning on postnatal day 21 (PND 21). Offspring from the dams began PBDE direct dosing on PND 12 and were dosed daily through PND 21. more...

Analysis of livers collected from postnatal day (PND) 22 and 13-week-old Wistar/Han rats exposed in utero to polybrominated diphenyl ether (PBDE) and directly dosed with PBDE. PBDEs are flame retardants. Results provide insight into the molecular basis of PBDE toxicities.

(Submitter supplied) To identify liver transcripts differentially expressed between control samples and animals exposed to DE-71, we collected RNA from male pups at postnatal day 4 (PND4) after the Wistar Han dams were exposed to 0, 0.1, 15, or 50 mg/kg DE-71. These samples were interrogated with the Affymetrix Rat Genome 230 2.0 GeneChip array A total of 0, 15, and 162 gene transcripts were differentially expressed between control samples and 0.1, 15, and 50 mg/kg DE-71, respectively (using a false discovery rate (FDR) threshold of 0.05). more...

(Submitter supplied) To identify liver transcripts differentially expressed between control samples and animals exposed to PBDE-47, we collected RNA from male pups at postnatal day 4 (PND4) after the Wistar Han dams were exposed to 0, 0.1, 15, or 50 mg/kg PBDE-47. These samples were interrogated with the Affymetrix Rat Genome 230 2.0 GeneChip array. A total of 7, 50, and 149 gene transcripts were differentially expressed between control samples and 0.1, 15, and 50 mg/kg PBDE-47 (using a false discovery rate (FDR) threshold of 0.05). more...

(Submitter supplied) Background: Polybrominated diphenyl ethers are a group of flame-retardant chemicals appearing increasingly in the environment. Their health effects and mechanisms of toxicity are poorly understood.Objectives: We screened for the sensitive effects and mechanisms of toxicity of 2,2 ,4,4 -tetra-bromodiphenyl ether (BDE-47) by analyzing the gene expression profile in rats exposed to doses comparable to human exposure.Methods: Wistar dams were exposed to vehicle or BDE-47 (0.002 and 0.2 mg/kg body weight) every fifth day from gestation day 15 to postnatal day 20 by injections to caudal vein. more...

Analysis of livers of animals exposed to low doses of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) from gestational day 15 to post-natal day 20. Polybrominated diphenyl ethers are flame-retardant chemicals used in consumer products. Results provide insight into the mechanisms of toxicity of BDE-47.

(Submitter supplied) We characterized gene expression changes in the developing mouse liver at gestational days (GD) 11.5, 12.5, 13.5, 14.5, 16.5, and 19.5 and in the neonate (postnatal day (PND) 7 and 30) using full-genome microarrays and compared these changes to that in the adult liver. The fetal liver, and to a lesser extent the neonatal liver, exhibited dramatic differences in gene expression compared to adults. Canonical pathway analysis of the fetal liver signature demonstrated increases in functions important in cell replication and DNA fidelity whereas most metabolic pathways of intermediary metabolism were suppressed. more...
