We report on a molecular cytogenetic characterization of 15q26 deletion and 2q37.1 duplication in a fetus presenting with intrauterine growth restriction (IUGR), diaphragmatic hernia, multicystic kidneys, left kidney pyelectasis, and clubfeet. A terminal 15q26 deletion and a terminal 2q duplication of at least 10 and 9 Mb, respectively, derived from a maternal translocation, were found. The 15q26 deletion represents a contiguous gene deletion syndrome mainly characterized by IUGR, congenital diaphragmatic hernia, and less frequently kidney defects...

BACKGROUND: It is well recognized that adverse events in utero can impair fetal development and lead to the development of kidney injury and hypertension in adulthood. We previously reported a lower kidney index, glomeruli number, and decreased glomerular filtration rate in intrauterine growth restriction (IUGR) offspring induced by maternal protein malnutrition. To explore the molecular mechanisms linking impaired fetal growth to renal diseases, we investigated differentially expressed proteins (DEPs) in the IUGR neonatal kidneys by isobaric tags for relative and absolute quantitation (iTRAQ) analysis...

Aspirin (acetylsalicylic acid) has been used ever since the Antiquity for its painkilling and anti-inflammatory effects. Its antiplatelet properties have then extended its indications to the field of coronaropathy and vascular cerebral disease, and finally to vascular placental disease. Aspirin has been widely prescribed since the 1980's to prevent pre-eclampsia, intra-uterine growth retardation and fetal death of vascular origin. It has also been proposed to prevent unexplained recurrent miscarriages. Its use during pregnancy is considered as safe, provided the daily doses do not exceed 100mg...

BACKGROUND: Placental malaria is a major cause of low birthweight, principally due to impaired fetal growth. Intervillositis, a local inflammatory response to placental malaria, is central to the pathogenesis of poor fetal growth as it impairs transplacental amino acid transport. Given the link between inflammation and autophagy, we investigated whether placental malaria-associated intervillositis increased placental autophagy as a potential mechanism in impaired fetal growth. METHODS: We examined placental biopsies collected after delivery from uninfected women (n = 17) and from women with Plasmodium falciparum infection with (n = 14) and without (n = 7) intervillositis...

Zinc is an essential micronutrient in pregnancy and zinc deficiency impairs fetal growth. We used a mouse model of moderate zinc deficiency to investigate the physiological mechanisms by which zinc is important to placental morphogenesis and the maternal blood pressure changes during pregnancy. A 26% reduction in circulating zinc (P = 0.005) was exhibited in mice fed a moderately zinc-deficient diet. Zinc deficiency in pregnancy resulted in an 8% reduction in both near term fetal and placental weights (both P < 0...

Vitamin D, besides its classical role in bone metabolism, plays a distinct role in multiple pathways of the feto-maternal unit. Calcitriol is the major active ligand of the nuclear vitamin D receptor (VDR). The vitamin D receptor (VDR) is expressed in different uteroplacental parts and exerts a variety of functions in physiologic pregnancy. It regulates decidualisation and implantation, influences hormone secretion and placental immune modulations. This review highlights the role of the vitamin D receptor in physiologic and disturbed pregnancy, as preeclampsia, fetal growth restriction, gestational diabetes and preterm birth...

Fetal growth restriction (FGR) in pregnancy is commonly caused by impaired uteroplacental blood flow. Vasodilators enhance uteroplacental perfusion and fetal growth in humans and animal models; however, detrimental maternal and fetal side effects have been reported. We hypothesised that targeted uteroplacental delivery of a vasodilator would enhance drug efficacy and reduce the risks associated with drug administration in pregnancy. Phage screening identified novel peptides that selectively accumulated in the uteroplacental vasculature of pregnant mice...

The placenta plays a major role in the development of fetal growth restriction, which affects 10% of pregnancies and contributes to chronic adult disease risk. We have reported that female rats born small develop cardiometabolic dysfunction only during pregnancy. The physiological tests performed during pregnancy induced a maternal stress response as indicated by increased maternal corticosterone concentrations. This stress effected placental growth compared to females who were unhandled during pregnancy. Maternal stress and growth restriction independently program F2 offspring metabolic dysfunction...
