Paternal Loss-of-Function Mutations of GNAS and Growth Retardation in a Mice Model: A Specific Placental Transcriptomic Signature?

Tran Lea Chantal , Ballandone Celine , Vaiman Daniel , Barbaux Sandrine , Richard Nicolas , Kottler Marie-Laure

Background: GNAS gene is a complex imprinted locus, resulting in the expression of at least four transcripts (XL, NESP55, A/B and Gsα) characterized by their specific exon 1 and common exons 2-13. While Gαs is biallelically expressed in most tissues, XL is only expressed from the paternal allele. Maternally inherited, loss-of-function mutations affecting those GNAS exons that ...

Dysregulation of Placental Mirna in Maternal Obesity is Associated with Pre-and Post-Natal Growth

Bassols Judit , Carreras-Badosa Gemma , Bonmati Alexandra , Ortega Francisco-Jose , Mercader Josep-Maria , Prats-Puig Anna , deZegher Francis , Ibanez Lourdes , Fernandez-Real Jose-Manuel , Lopez-Bermejo Abel

Background: Human placenta exhibits a specific miRNA expression pattern. Some of these miRNAs are dysregulated in pregnancy disorders like preeclampsia and intrauterine growth restriction (IUGR), and are potential biomarkers for these pathologies. No studies have been performed in maternal obesity.Objective and hypotheses: (1) Define the placental miRNA profile in pregnant women with: a) pre-pregnancy (preOB) or gestational obesity (gestOB), b) gestation...

Vitamin D Depletion in Pregnancy Decreases Survival Time, Oxygen Saturation, Lung Weight and Body Weight in Preterm Rat Offspring

Lykkedegn Sine , Sorensen Grith Lykke , Beck-Nielsen Signe Sparre , Pilecki Bartosz , Duelund Lars , Marcussen Niels , Christesen Henrik Thybo

Background: Animal studies suggest a role of vitamin D in fetal lung development although not studied in preterm animals.Objective and hypotheses: We tested the hypothesis that vitamin D depletion does not aggravate respiratory insufficiency in preterm rat offspring. Furthermore, the effects of vitamin D depletion on growth and lung surfactant were investigated.Method: Female Sprague-Dawley rats were randomly assigned low vitamin D...

Pharmacokinetics of Intravenous Glucagon in Children with Hyperinsulinaemic Hypoglycaemia

Shah Pratik , Rahman Sofia , Gilbert Clare , Morgan Kate , Hinchey Louise , Bech Paul , Amin Rakesh , Hussain Khalid

Background: Hyperinsulinaemic hypoglycaemia (HH) is one of the common causes of hypoglycaemia in infants and children. It can cause severe brain injury in children if not treated promptly. Diazoxide is first-line treatment for HH. Glucagon infusion is used in the management of children with HH. However it is unclear what dose of glucagon should be used in children.Objective and hypotheses: To evaluate the efficacy, safety and pharmacokinetics of intraven...

Phenotype, Genotype and Short term Outcome in Congenital Hyperinsulinism (CHI)

Dhingra Mudita , Rao Sudha , Dighe Neha , Parikh Ruchi , Joshi Madhura , Kondpalle Sandhya , Limaye Aparna , Joshi Rajesh , Desai Meena P

Background: Congenital Hyperinsulinism (CHI) is the commonest cause of refractory hypoglycaemia in infants.Objective and hypotheses: CHI is a rare disorder with varied clinical manifestations, genotype often with poor outcome. This study describes the clinical profile, molecular characterisation, response to therapy and short term outcome in children with CHI presenting to Paediatric Endocrinology Division, B.J. Wadia Hospital for Children, Mumbai.<p...

Increased Islet Cell Neogenesis and Endocrine Cell Differentiation in Congenital Hyperinsulinism in Infancy

Hardwick Elise , Han Bing , Salomon-Estebanez Maria , Padidela Raja , Skae Mars , Craigie Ross , Cosgrove Karen , Banerjee Indi , Dunne Mark

Background: Congenital Hyperinsulinism in Infancy (CHI) is characterised by inappropriate insulin release. We currently attribute hypoglycaemia to β-cell dysfunction because of defects in the ion channel genes ABCC8 or KCNJ11. However, the CHI pancreas is also associated with inappropriate expression of foetal-like transcription factors and enhanced cell proliferation.Hypothesis: As the CHI pancreas bears similarities to the foetal pancreas, we hypo...

Expression of Insulin Receptor Isoforms and Type 1 Insulin-Like Growth Factor Receptor in the Placenta as a Function of Fetal Weight

Barasha Hanin , Gepshtein Vardit , Windeblaum Gizi , Verbitsky Oleg , Solt Ido , Tiosano Dov

Background: Fetal growth is the fastest of all periods of growth in human life, mainly due to cellular hypertrophy and proliferation. It was recently discovered that the metabolic and mitogenic effects of Insulin are mediated by two Insulin Receptors (IR) isoforms, IR-A and IR-B. High expression of IR-A indicates proliferation and differentiation whereas IR-B indicates metabolic dominance.Objective and hypotheses: The aim of the study was to examin the e...

Gestational Diabetes is Associated with Changes in Placental Microbiota and Microbiome

Bassols Judit , Serino Matteo , Carreras-Badosa Gemma , Burcelin Remy , Blasco-Baque Vincent , Prats-Puig Anna , de Zegher Francis , Ibanez Lourdes , Fernandez-Real Jose-Manuel , Lopez-Bermejo Abel

Background: The human microbiota has emerged as an unexpected modulator of the immune system. The placenta, long thought to be sterile, harbors a unique microbiome and variations in their composition could be related to prevent pregnancy disorders.Objective and hypotheses: To profile the placental microbiota (microorganisms) and microbiome (collection of microbial genomes in an environment) in women with gestational diabetes (GDM) and study their relatio...
