In our model, fifteen of the tested pesticides were found to agonize the ERalpha-mediated transcription in a dose-dependent manner and DDT, trans-nonachlor, chlordane, fenvalerate and toxaphene were also capable to activate ERbeta.

Together, our results suggest that endosulfan and chlordane could indeed modulate an estrogen-inducible gene such as PRL, possibly acting via second messenger-mediated cellular mechanisms instead of solely competing with estrogens for the nuclear estrogen receptor sites.

Recent in vitro data suggest that the interaction between some weakly estrogenic organochlorines, dieldrin, endosulfan, toxaphene, and chlordane, causes a synergistic increase in their estrogenic potency, an effect due to joint action on estrogen receptors (ER).

Determination of interactive effects of the (pseudo-) estrogens nonylphenol, o,p'DDT, chlordane, endosulfan, dieldrin, and methoxychlor revealed that, in combination with 3 pM E2, (pseudo-) estrogens were additive.

Suppression of ERRalpha activity by chlordane (an antagonist of ERRalpha) or small interfering RNA knockdown of ERRalpha blocked the increase of expression and promoter activity of aromatase induced by PGE2.

The environmental chemicals included the insecticide chlordane, which has no estrogenic activity, and the pesticides dieldrin and toxaphene, which have very weak estrogenic activity.

To determine whether environmental chemicals had the potential to function as exogenous hormones in the American alligator, we examined the ability of chemicals to bind the estrogen receptor (aER) and progesterone receptor (aPR) in a protein extract prepared from the oviduct of the alligator.
To test the effect of chemicals identified in alligator eggs from Lake Apopka on [3H] 17 beta-estradiol binding, we mixed these chemicals at concentrations measured in eggs in the competition binding assay. 2,2-bis (4-chlorophenyl)-N-(methoxymethyl) acetamide (p,p'-DDD) and trans-nonachlor, both found in Lake Apopka, interacted with aER, whereas others such as chlordane and toxaphene did not.

While estrogen receptor (ER)-targeted therapeutics have clearly been a success in the treatment of breast cancer, the orphan estrogen-related receptors (ERRs) represent novel targets for future development.
The organochlorine pesticides toxaphene and chlordane, and the synthetic compound XCT790 antagonize ERRalpha.

Several crosstalks between the estrogen receptor and other signaling pathways may influence the estrogenic stimulation of cell growth.
Cells were treated with two known xenoestrogens, endosulfan and chlordane, alone or in the presence of insulin-like growth factor-1 and epidermal growth factor, respectively, and their growth was measured using the 2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxyanilide proliferation assay.

Toxaphene was also tested for its ability (1) to bind the estrogen receptor (ER) in a competitive binding assay using recombinant human ERalpha (rhER) and in a whole-cell competitive ER binding assay, and (2) to alter the catabolism of E2 in MCF-7 cell cultures.
Results from the MCF-7 focus assay showed: (1) Toxaphene alone was not estrogenic between the concentrations of 0.5 nM and 10 microM, (2) toxaphene in binary combinations with chlordane, dieldrin, or endosulfan (alpha or beta) was not estrogenic, and (3) toxaphene was weakly antiestrogenic (it reduced the number of foci induced by 0.1 nM and 0.01 nM E2).

In gel retardation assays, this sequence forms a low-mobility complex that migrates like an estrogen receptor tetramer.
This synergistic effect was observed using either the natural hormone (17-beta-estradiol) or xenoestrogens (phenol red, chlordane).

Treatment with 10 (-6)-10 (-4) M chlordane, dieldrin, toxaphene, or an equimolar mixture of dieldrin/toxaphene did not induce activity, whereas 10 (-4) M endosulfan caused a 2000-fold increase in beta-gal activity.
