93289 Hammond B, Katzenellenbogen BS, Krauthammer N, McConnell J: Estrogenic activity of the insecticide chlordecone (Kepone) and interaction with uterine estrogen receptors. Proc Natl Acad Sci U S A. 1979 Dec;76(12):6641-5.

When injected into immature rats, chlordecone translocates estrogen receptor sites to the uterine nucleus, increases uterine weight, and stimulates the synthesis of the progesterone receptor, an estrogen receptor-mediated process.

Chlordecone treatment on diestrus 2 reduced the number of progesterone receptors in uterine tissue of females on the predicted day of proestrus.

The ability of the chlorinated pesticide chlordecone to induce the CNS (hypothalamus and preoptic area) plus pituitary and uterine progesterone receptors was examined in CDF-344 female rats following treatment with 25 micrograms estradiol or with 75 mg/kg chlordecone.

To examine this further, we compared the effects of estrogenic (o,p'-DDT [1-(o-chlorophenyl)-1-(p-chlorophenyl) 2,2,2-trichloroethane] and Kepone, chlordecone) and nonestrogenic (p,p'-DDD [1,1-dichloro-2,2-bis (p-chlorophenyl) ethane], a metabolite of p,p'-DDT) xenobiotics with those of 17beta-estradiol (E2) and 4-hydroxyestradiol-17beta (4-OH-E2), a catechol metabolite of E2, on uterine expression of lactoferrin (LF) and progesterone receptor (PR).

Furthermore, chlordecone attenuated the increase in progesterone receptors seen after estradiol treatment.

The tested chemicals are organochlorine insecticides (DDT and its metabolites, methoxychlor, aldrin, dieldrin, chlordecone, lindane, trichlorobenzene), estrogenic insecticides (endosulfan, toxaphene, nonachlor), herbicides (alachlor and atrazine), fungicides (benomyl and vinclozolin), industrial chemicals (nonylphenol, bisphenol A, diphenylphtalate), antioxidants (butylated hydroxyanisol) and some phytoestrogens.

In addition, these compounds stimulated transcription of the vitellogenin estrogen-response element via the ER in a transcriptional reporter gene assay and induced the expression of an endogenous estrogen-responsive gene, the progesterone receptor (PR).

Chlordecone (kepone; 40 mg/kg; i.p.) was used in Study 2 as a positive control for the alteration of the estrogen-induction of PR in the pituitary.
