Obesity of women at conception is increasing, a condition associated with offspring obesity. We hypothesized that maternal obesity increases placental fatty acid transporter (FATP) expression, enhancing delivery of fatty acids to their fetuses. Sheep are a commonly utilized biomedical model for pregnancy studies. Nonpregnant ewes were randomly assigned to a control group [100% of National Resea...

Atherosis of spiral arteries in uteroplacental beds from preeclamptic women resemble those of atherosclerosis, characterized by increased plasma lipids and lipoproteins. We hypothesized that: 1) lipoprotein receptors/transporters in the placenta would be upregulated in preeclampsia, associated with increased maternal and fetal lipoprotein concentrations; and 2) expression of these would be redu...

Mammalian oocytes accumulate a large pool of mRNA molecules that orchestrate subsequent embryonic development. The transcriptional machinery is silent during oocyte meiotic maturation and early embryogenesis, and thereby the early decisive events in embryo development prior to initiation of transcription from the embryonic genome are directed by the translation of pre-existing maternal mRNAs. O...

Growing evidence suggests that maternal immune activation has a significant impact on the immuno-competence of the offspring. The present study aimed to characterize region-specific effects of maternal immune activation on the offspring's neuroimmune function. The offspring born to dams treated with saline or lipopolysaccharide (LPS) at gestational day 18 was stimulated with saline or LPS at po...

OBJECTIVE To develop a model for prediction of late preeclampsia (PE; which develops at or after 34 weeks' gestation) based on maternal history and characteristics, mean arterial pressure (MAP), and circulating levels of mRNA for the placenta-specific 1 (PLAC1) gene in maternal plasma at 14-18 weeks' gestation. METHOD This was a screening study of singleton pregnancies at 14-18 weeks' gestati...

Anopheles stephensi is a principal vector of urban malaria on the Indian subcontinent and an emerging model for molecular and genetic studies of mosquito biology. To enhance our understanding of female mosquito reproduction, and to develop new tools for basic research and for genetic strategies to control mosquito-borne infectious diseases, we identified 79 genes that displayed previtellogenic ...

OBJECTIVES Previous data have shown that inhibin A (alpha/betaA) is increased about twofold in maternal serum samples from Down syndrome pregnancy. Our objectives were to determine whether activin A (betaA/betaA) was similarly increased in maternal serum from pregnancies affected with fetal Down syndrome, and to investigate whether increased expression of each inhibin/activin subunit occurred i...
