BACKGROUND The placenta acts not only as a conduit of nutrient and waste exchange between mother and developing fetus but also functions as a regulator of the intrauterine environment. Pre-eclampsia (PE) and gestational diabetes mellitus (GDM) are leading causes of complications during pregnancy. Pathophysiologies show that they are associated with one(More)
To determine the effect of perinatal exposure to nicotine on water intake and salt appetite related to renin-angiotensin system in the offspring, maternal rats during perinatal period [gestation (G) or gestation plus lactation (G+L)] were subcutaneously administrated with nicotine. Four months after birth, intake of 1.8% NaCl and water was measured(More)
Early-onset preeclampsia (EOPE), which is the most severe form of the syndrome, confers a high risk of neonatal morbidity and perinatal death. We aim to study the roles of long non-coding RNAs (lncRNAs) in the pathogenesis of early-onset preeclampsia (EOPE). Therefore, we examined the expression profiles of lncRNAs between early-onset preeclampsia and(More)
This study determined the long-term influence of prenatal nicotine exposure (PN) on blood pressure and vascular functions in the aged offspring rats. PN did not affect body weight and plasma adrenocorticotropic hormone level; however, it significantly reduced plasma angiotensin I and angiotensin II in both sexes. Systolic pressure in the male aged PN(More)
DNA methylation is an epigenetic event involved in a variety array of processes that may be the foundation of genetic phenomena and diseases. DNA methyltransferase is a key enzyme for cytosine methylation in DNA, and can be divided into two functional families (Dnmt1 and Dnmt3) in mammals. All mammalian DNA methyltransferases are encoded by their own single(More)
BACKGROUND/AIMS The invasion of trophoblast cells into the maternal uterine decidua is critical for normal placentation, establishment of pregnancy and maintenance of fetal growth in humans. Several growth factors and cytokines have been implicated in trophoblast invasion, but the underlying regulatory mechanisms of invasion are not fully understood. Our(More)
Long non-coding RNAs (lncRNAs) are key regulatory molecules that are involved in a variety of biological processes and human diseases. Their impact on early onset preeclampsia remains unclear. In this study, we tested the expression of RPAIN (transcript variant 12 of RPA interacting protein, a non-coding RNA, NR_027683.1) in placenta tissues derived from 25(More)
INTRODUCTION Pathogenesis of early-onset preeclampsia (PE) is generally recognized by impaired trophoblast invasion of the myometrial arteries, which results in placental insufficiency. Recently, we reported that CDX1 is hypermethylated in the human preeclampsia placenta. However, whether CDX1 participates in trophoblast invasion has not been clearly(More)
BACKGROUND/AIMS Exosomes are extracellular vesicles that are involved in several biological processes. The roles of proteins from human umbilical cord blood exosomes in the pathogenesis of preeclampsia remains poorly understood. METHODS In this study, we used high-resolution LC-MS/MS technologies to construct a comparative proteomic profiling of human(More)
AIMS This study aimed to identify the different expression of circular RNAs (circRNAs) in the placental tissues of pregnant women with preeclampsia (PE) and to provide a new avenue of research regarding the pathological mechanisms of PE. METHODS In this study, we collected 40 placental tissues from PE patients and 35 placental tissues from gestational(More)
