- Modulatory role of EDCs on ovarian adiponectin and its receptor expression.
- Dioxin-like compounds decreased, while non-dioxin-like increased adiponectin.
- Opposite effect on adiponectin stimulated steroidogenesis.
- Dioxin- like compounds may contribute to obesity-related ovarian disorders.
We determined the effect of dioxin-like polychlorinated naphtalenes (PCN) (Halowax 1051) (100 pg/ml), benzo(a)pyrene [B(a)P] (2.5 ng/ml), hexachlorobenzene (HCBz) (0.2 ng/ml) and non-dioxin like polybrominated diphenyl ether (BDE-47) (25 ng/ml) and bisphenol A (BPA) (20 ng/ml) on ovarian adiponectin secretion (ELISA) and its receptors expression (Western blot). Ovarian cells co-culture was used to examine action of endocrine disruptors (EDCs) on adiponectin (10 μg/ml) stimulated steroidogenesis. B(a)P, HCBz, testosterone (T) decreased adiponectin secretion and receptors expression, BPA, BDE-47, estradiol (E2) had the opposite effect, while PCN had inhibitory effect only on adiponectin secretion. In adiponectin stimulated cells dioxin-like compounds decreased E2 and except of PCN had no effect on T, while non-dioxin like increased E2 and decreased T secretion. Results indicated to modulatory role of EDCs on adiponectin and its receptor and its action on ovarian steroidogenesis, suggest that dioxin- like compounds may contribute to the ovarian dysfunction in obesity-related disorders.
