Reductive metabolism of p,p'-DDT and o,p'-DDT by rat liver cytochrome P450.
The in vitro metabolism of p,p'-DDT [1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane], an important environmental pollutant, was examined in rat liver, focusing on reductive dechlorination. When p,p'-DDT was incubated with liver microsomes of rats in the presence of NADPH or NADH, a dechlorinated metabolite, p,p'-DDD [1,1-dichloro-2,2-bis(4-chlorophenyl)ethane], was formed under anaerobic conditi...
متن کاملDirect effect of p,p'-DDT on mice liver
Contact with the pesticide dichlorodiphenyltrichloroethane (p,p′-DDT) can be the cause of various harmful effects in humans, wildlife, and the environment. This pesticide is known to be persistent, lipophilic, resistant to degradation, and bioaccumulive in the environment and to be slowly released into bloodstream. Growing evidence shows that exposure to DDT is linked to type 2 diabetes mellitu...

* Inquiries regarding this paper should be addressed to M. S. Dunn, University of California, Los Angeles. The experimental data are from a dissertation submitted by Joseph D. Pinto to the Graduate School of the University of California, Los Angeles, in partial fulfillment of the requirements for the degree of Doctor of Philosophy. The chemical names and structures for DDT and its derivatives, ...
متن کاملTranscriptional effects of Organochlorine o,p′-DDT and its Metabolite p,p′-DDE in Transfected MDA-MB 231 and MCF-7 Breast Cancer Cell Lines
Background: The organochlorine DDT has estrogenic activity but the mechanism underlying the estrogenic activity of this pesticide remains unclear. In the present investigation here, we studied the transcriptional effects of a synthetic organochlorine pesticide o,p’-DDT [1.1.1.-trichloro-2-(o-chlorophenyl)-2-p-chloriphenyl ethane] and its metabolite p,p'-DDE (2-2-bis(4/chlorophenyl)-1-1-di...
متن کاملEffect of single and repeated in vitro exposure of ovarian follicles to o,p'-DDT and p,p'-DDT and their metabolites.
The aim of the presented study was to compare the effect of o,p'-DDT [1,1-dichloro-2,2-bis-(p,p'-chlorophenyl)-ethylene] and p,p'-DDT [1,1,1-trichloro-2,2-bis-(p-chlorophenyl)-ethane] and their metabolites DDE and DDD on estradiol secretion by ovarian follicles, the target organs of environmental estrogens. Theca interna (Tc) and granulosa cells (Gc) were collected from medium size porcine foll...
