BACKGROUND The reproductive consequences and mechanisms of action of chronic exposure to low-dose endocrine disruptors are poorly understood. OBJECTIVE We assessed the effects of a continuous, low-dose exposure to a phytoestrogen (genistein) and/or an antiandrogenic food contaminant (vinclozolin) on the male reproductive tract and fertility. METHODS(More)
Endometriosis is a common gynecological disorder characterized by pain and infertility, where the lesions disseminate everywhere in the body with a preference for the pelvis. In that, it could be regarded as a benign metastatic disease, because its issue is not fatal. However, the molecular bases of this intriguing clinical condition are not well known. The(More)
BACKGROUND Assisted Reproductive Technologies (ART) are increasingly used in humans; however, their impact is now questioned. At blastocyst stage, the trophectoderm is directly in contact with an artificial medium environment, which can impact placental development. This study was designed to carry out an in-depth analysis of the placental transcriptome(More)
BACKGROUND Mutations in STOX1 were proposed to be causal for predisposing to preeclampsia, a hypertensive disorder originating from placental defects, affecting up to 10% of human pregnancies. However, after the first study published in 2005 three other groups have dismissed the polymorphism described in the first paper as a causal mutation. METHODOLOGY(More)
Genomic imprinting characterizes genes with a monoallelic expression, which is dependent on the parental origin of each allele. Approximately 150 imprinted genes are known to date, in humans and mice but, though computational searches have tried to extract intrinsic characteristics of these genes to identify new ones, the existing list is probably far from(More)
Intra-uterine growth restriction (IUGR) is a frequent disease, affecting up to 10% of human pregnancies and responsible for increased perinatal morbidity and mortality. Moreover, low birth weight is an important cause of the metabolic syndrome in the adult. Protein depletion during the gestation of rat females has been widely used as a model for human IUGR.(More)
Preeclampsia (PE) and vascular intra-uterine growth restriction (vIUGR) are two pathological obstetrical conditions originating from placental dysfunction. Recently, methylation changes at the placental level have been shown to be indicative of these diseases. The alteration of such epigenetic marks is therefore a novel pathway that might be critical for(More)
In this study, low birth weight was induced in rats by feeding the dams with a low-protein diet during pregnancy. Kidneys from the fetuses at the end of gestation were collected and showed a reduction in overall and relative weight, in parallel with other tissues (heart and liver). This reduction was associated with a reduction in nephrons number. To better(More)
The status of the corticosteroid-binding globulin (CBG) at the fetomaternal interface, especially in the maternal intervillous blood space (I), was investigated and compared to that of CBG in the maternal (M) and fetal (umbilical arteries [A] and vein [V]) peripheral circulations at term. Immunoquantitation of plasma CBG showed that the CBG concentration in(More)
A low-protein diet applied during pregnancy in the rat results in intrauterine growth restricted (IUGR) fetuses. In humans, IUGR is associated with increased perinatal morbidity, higher incidence of neuro-developmental defects and increased risk of adult metabolic anomalies, such as diabetes and cardiovascular disease. Development and function of many(More)
