Abstract
Workshops are an important part of the IFPA annual meeting as they allow for discussion of specialized topics. At IFPA meeting 2016 there were twelve themed workshops, four of which are summarized in this report. These workshops covered innovative technologies applied to new and traditional areas of placental research: 1) genomic communication; 2) bioinformatics; 3) trophoblast biology and pathology; 4) placental transport systems.

Brass E, Hanson E, O'Tierney-Ginn PF. Placental oleic acid uptake is lower in male offspring of obese women. Placenta 2013; 34:503-9. [PMID: 23602336 DOI: 10.1016/j.placenta.2013.03.009] [Citation(s) in RCA: 60] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [What about the content of this article?

Abstract
INTRODUCTION The fetus is dependent on the placenta for its supply of long chain polyunsaturated fatty acids (LCPUFA), which are essential in fetal growth and development. Previous work suggests that high maternal body mass index (BMI) inhibits fetal LCPUFA delivery and males have greater fatty acid requirements than females during development. We hypothesized that male placental fatty acid uptake would be more sensitive to maternal BMI compared to females. METHODS Term placental samples were collected from healthy women receiving Cesarean section (n = 38). Placental fatty acid transporter and binding protein gene expression and uptake of oleic acid (OA), arachidonic acid, (AA) and docosahexanoic acid (DHA) were measured. Two-way ANOVA was used to assess the effects of fetal sex and maternal overweight/obesity (BMI >26 kg/m2). RESULTS Placental fatty acid uptake of OA was 43% lower in male offspring and 73% higher in female offspring of obese compared to normal BMI women (P < 0.05). The interaction between fetal sex and maternal BMI had a significant effect on both OA (P = 0.002) and AA uptake (P = 0.01). DHA uptake was not affected by fetal sex or maternal obesity. Placental fatty acid transporter CD36 and binding protein FABP5 gene expression levels were lower in male offspring of obese mothers but were not affected by BMI among females. CONCLUSION Maternal obesity and fetal sex significantly affect the placental uptake of oleate and arachidonate. Placental fatty acid uptake in both male and female fetuses is sensitive to maternal BMI, but males may have inadequate acquisition of the unsaturated fatty acid OA, when exposed to maternal obesity.
