Abstract

Objective

Ethanol exposure during pregnancy may result in fetal alcohol syndrome (FAS). The mechanism by which this occurs is unknown. Recent studies in several organ systems, including the placenta, suggest that oxidative stress is involved. In this study we investigated the presence and levels of three oxidative stress markers in placental villous tissue exposed to ethanol.

Methods

Villous tissues from normal placentas were perfused with Dulbeco’s modified Eagle’s medium (DMEM) with HEPES buffer, sodium bicarbonate, and glucose at pH 7.4. After stabilization, 100 mM ethanol was added to the pefusate. After 2 hours of pe fusion, the tissue was removed, fixed and stained for nitrotyrosine, 4-hydroxy-2-nonenal (4HNE) and 8-hydroxyguano sine (8-OHDG). Staining within the trophoblasts was quantified with densitometry.

Results

Nitrotyrosine and 4HNE immunostaining was seen in the trophoblasts. 4HNE was also seen in the stroma. In contrast, 8-OHDG was seen only in the stroma and endothelial cells in the fetal circulation. Ethanol exposure significantly increased nitrotyrosine levels in the trophoblasts beyond levels in the control tissue. Nitrotyrosine and 8-OHDG levels were also increased in stroma.

Conclusion

Within the placental villi, markers of oxidative stress are present in the trophoblasts and stroma after a short period of ethanol exposure. There is an increase in oxidative stress, primarily involving the nitric oxide pathway, in the trophoblasts as well as DNA damage in the stroma. Lipid peroxidation is not acutely changed in our 2-hour exposure window. (J Soc Gynecol Investig 2006; 13: 118—21) Copyright © 2006 by the Society for Gynecologic Investigation.
