Interaction of alcohol & phosphatidic acid in maternal rat uterine artery function

Alcohol has been demonstrated to impair maternal uterine arterial adaptations in Fetal Alcohol Spectrum Disorder (FASD) animal models. However, the exact mechanism remains inconclusive. We hypothesized that phosphatidic acid (PA), a direct target of alcohol metabolism, would alleviate alcohol-induced vascular dysfunction of the maternal uterine artery. Mean fetal weight, and crown-rump length of the alcohol administered rats were ~9 % and 7.6 % lower than the pair-fed control pups, respectively. Acetylcholine (Ach)-induced uterine artery relaxation was significantly impaired in uterine arteries of alcohol-administered rats (P 0.05). Supplementation of 10
