Exposure of Mouse Preimplantation Embryos to 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) Alters the Methylation Status of Imprinted Genes H19 and Igf21

1 Jun 2004

Abstract excerpt

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is an extremely toxic, persistent environmental contaminant that disrupts normal development in laboratory animals. In our earlier study, we found that exposure of preimplantation embryos to TCDD markedly induced cytochrome P4501A1 mRNA at the blastocyst stage. In the present study, to determine whether exposure of preimplantation embryos to TCDD affects fetal growth, we...
