2005 Trophoblast Research Award Lecture: Defects in the keratin cytoskeleton disrupt normal murine placental development and trophoblast cell function.

abstract：BACKGROUND:Previous studies have shown that pregnancies complicated by placentas with an isolated single umbilical artery (iSUA) are at increased risk for small-for-gestational-age (SGA) births. The etiology of SGA in this population, however, remains unknown. OBJECTIVE:The primary objective of this study was to evalu...

abstract：INTRODUCTION:Maternal nutrition is an extremely important health issue. We evaluated the impact of maternal high fat diet (HFD) on pregnancy outcomes, elucidated how the rat placenta and fetus respond to diet manipulation based on fetal sex, and identified candidate genes and pathways. METHODS:Rats were fed a normal o...

abstract：:Intrauterine growth and development can impact upon the long-term health of an individual. The fetus is dependent upon the placenta for its supply of nutrients and oxygen from the mother. In turn, the functional capacity of the placenta to supply that demand is under the control of the fetal and maternal genomes. Rece...
