OBJECTIVE: We examined low concentrations of XEs [dieldrin, endosulfan, o', p'-dichlorodiphenyl-ethylene (DDE), nonylphenol (NP), and bisphenol A (BPA)] for nongenomic actions via action of membrane estrogen receptors (ERs).
METHODS: We measured activity of the dopamine transporter (DAT) by the efflux of 3H-dopamine in nontransfected nerve growth factor-differentiated PC12 rat pheochromocytoma cells expressing membrane DAT, ER-alpha, ER-beta, and G-protein-coupled receptor 30.

The reconstituted organochlorine mixture contained 1,1,1-trichloro-2-(p-chlorophenyl)-2-(o-chlorophenyl) ethane, 1,1,1-trichloro-2,2-bis (p-chlorophenyl) ethane, 1,1-dichloro-2,2-bis (p-chlorophenyl) ethylene, endosulfan-1, endosulfan-2, p,p'-methoxychlor, and toxaphene; the relative proportion of each chemical in the mixture resembled the composition reported in a recent U.S.
The following battery of in vitro 17 beta-estradiol (E2)-responsive bioassays were utilized in this study: competitive binding to mouse uterine estrogen receptor (ER); proliferation in T47D human breast cancer cells; luciferase (Luc) induction in human HepG2 cells transiently cotransfected with C3-Luc and the human ER, rat ER-alpha, or rat ER-beta; induction of chloramphenicol acetyltransferase (CAT) activity in MCF-7 human breast cancer cells transfected with E2-responsive cathepsin D-CAT or creatine kinase B-CAT plasmids.

RESULTS: The estrogenic compounds 17beta-estradiol, genistein, bisphenol A, and endosulfan produced similar protein profile changes in MCF-7 cells (phenotype: ERalpha (+)/ERbeta (+)), but had no effect on MDA-MB-231 (ERalpha (-)/ERbeta (+)), MCF-10F (ERalpha (-)/ERbeta (+)), or MCF-10A (ERalpha (-)/ERbeta (-)) cells.

The alkylphenolic compounds (4-octylphenol and 4-nonylphenol) displayed some ability to displace 3H-E2 binding from ERalpha and beta at high concentrations, but dieldrin and atrazine had little binding activity for both ER subtypes and endosulfan for ERbeta.

We tested the effect of these nine pesticides on the human ERalpha and ERbeta mRNA steady state levels in the mamma cancer fibroblast MCF-7BUS cells using on-line RT-PCR.
Endosulfan and pirimicarb alone decreased the ERalpha mRNA level weakly.

In this report, forty-nine pesticides were tested for ERalpha and beta activation or inhibition in stable reporter cell lines, HELN ERalpha and ERbeta.
Antagonistic activities toward hERalpha and hERbeta were shown in three (carbaryl, pentachlorophenol and 2,4,5-trichlorophenoxyacetic acid) and seven (chlordecone, methoxychlor, carbaryl, endosulfan, endrin, dieldrin, aldrin) pesticides, respectively.

The assays were 1) competitive binding with the mouse uterine estrogen receptor, 2) transcriptional activation in HeLa cells transfected with plasmids containing an estrogen receptor and a response element, and 3) the uterotropic assay in mice.
The chemicals studied were 17 beta-estradiol, diethylstilbestrol, tamoxifen, 4-hydroxytamoxifen, methoxychlor, the methoxychlor metabolite 2,2-bis (p-hydroxyphenyl)-1,1,1-trichloroethane (HPTE), endosulfan, nonylphenol, o,p'-DDT, and kepone.
