Ovarian cancer is the most frequent cause of cancer death among all gynecologic cancers. We demonstrate here that lysophosphatidic acid (LPA)-induced ectodomain shedding of heparin-binding EGF-like growth factor (HB-EGF) is a critical to tumor formation in ovarian cancer. We found that among the epidermal growth factor receptor (EGFR) family of growth(More)
In this study, we divided 26 fetuses at 32-37 weeks of gestation into three groups using combined criteria of gestational age and behavioral indicators. We investigated fetal habituation to vibroacoustic stimulation (VAS). Fetuses showed habituation from at least 32 weeks of gestation. Furthermore, fetuses less developed from behavioral standpoint took(More)
The aim of this study is to investigate the placental transport mechanism of cationic compounds by comparison of the uptake of an organic cation into human placental basal membrane vesicles (BLMVs) with that into organic cation transporter 3 (OCT3)-expressing cells. Reverse transcription-polymerase chain reaction analysis demonstrated that OCT3 is the only(More)
PURPOSE The purpose of this study is to attempt to characterize patients with unfavorable clinical outcome by the relative mRNA levels of ABC transporter expression in their tumor samples and to examine whether relative mRNA levels of each of the ABC transporters can be a useful predictor of progression-free survival in advanced ovarian carcinoma.

Periconceptional folate supplementation is widely believed to have significant preventive effects on the production of neural tube defects. Folate-binding protein 1 (FBP1) is one of the membrane proteins that mediate cellular uptake of folate. Although recent studies suggest that Fbp1 is essential for neural tube closure, the pattern of Fbp1 expression in(More)
The aim of this study was to investigate developmental changes in heart rate response to repeated low-intensity (85 dB) sound stimulation in fetuses between 32 and 37 weeks of gestation. We measured amplitude changes in heart rate as our index of fetal response. At 35 to 37 weeks of gestation, the majority of fetuses showed a deceleratory response at the(More)
We investigated the transport of salicylic acid and L-lactic acid across the placenta using the human trophoblast cell line BeWo. We performed uptake experiments and measured the change in intracellular pH (pH(i)). The uptakes of [(14)C]salicylic acid and L-[(14)C]lactic acid were temperature- and extracellular pH-dependent and saturable at higher(More)
BACKGROUND Maternal exposure to polychlorinated biphenyls (PCBs) is associated with increased proportions of spontaneous abortion and stillbirth in animal studies. In Japan in 1968, accidental human exposure to rice oil contaminated with PCBs and other dioxin-related compounds, such as polychlorinated dibenzofurans (PCDFs), led to the development of what(More)
BACKGROUND Neutrophil activation has been implicated in the pathophysiology of preeclampsia. The aim of this study was to investigate whether neutrophil-derived reactive oxygen species (ROS) modulate adhesion to endothelial cells in preeclampsia. METHODS We first assessed neutrophil superoxide production and neutrophil-endothelial cell adhesion in normal(More)
