In this report, forty-nine pesticides were tested for ERalpha and beta activation or inhibition in stable reporter cell lines, HELN ERalpha and ERbeta.

The cell proliferation, the up-regulation of pS2, and the down-regulation of ERalpha and ERbeta gene expressions induced by the racemate and enantiomers of o,p'-DDT were all reversed by cotreatment with 10 (-6) mol/L ICI 182,780.

While it is clear the ERbeta subtypes are the products of different genes (due to a gene duplication in teleosts) the differences in their responses to MXC and its metabolites indicate that their functions diverge, both in their in vivo molecular response to E (2), as well as in their interaction with endocrine disrupting compounds found in the wild.

To understand the molecular mechanisms of estrogen action and to evaluate estrogen receptor ligand interactions in amphibians, we isolated cDNAs encoding the estrogen receptors (ERalpha and ERbeta) from the Japanese firebelly newt (Cynops pyrrhogaster), Tokyo salamander (Hynobius tokyoensis), axolotl (Ambystoma mexicanum), and Raucous toad (Bufo rangeri).

However, the hormones, for example, LH in the women blood and P in the cords blood decreased respectively with the rising pesticides' levels and an obvious dose-effect relationship was found. (2) The expressional abundances of alpha-estrogen receptor (alpha-ER), beta-endorphin (beta-EP) and gonadotropin releasing hormone (GnRH) in the placentae and alpha-ER and beta-EP in the cord tissues went up respectively in dose-effect manner following the rising pesticides' burdens. (3) The times of the previous adverse pregnancy outcomes increased with the increase of the residues' burdens and there were significant differences between the control and various residue groups, but the times in the high-residue was smaller than that in the mid-residue group (P < 0.01).
