Protective effect of resveratrol on urogenital sinus and prostate development in rats exposed in utero to TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin).

This study evaluated the protective effects of resveratrol on the prostate development of rats exposed to TCDD. Pregnant rats received TCDD (1 μg/kg) at GD15 and/or RES (20 mg/kg/day) from GD10 to PND21. Newborn and adult males from Control, TCDD, TCDD + RES and RES groups were euthanized and the prostate was excised.

Alterations in prostate morphogenesis in male rat offspring after maternal exposure to Di-n-butyl-phthalate (DBP).

Prostate morphogenesis is regulated by androgens hormones and modulated by morphogenetic proteins such as Bone Morphogenetic Proteins (BMPs). This study aims to investigate the effects on prostate development in male offspring and differentiation after gestational and lactational maternal exposure to Di-n-butyl-phthalate (DBP), an important environmental contamination. Pregnant Wistar rats received 100 or 500mg/kg of DBP (DBP100 and DBP500), by gavage, from gestation day 15 (GD15) until postnatal day 21 (PND21).
