Circulating miR-451a: A Biomarker to Guide Diagnosis and Treatment of Polycystic Ovary Syndrome in Adolescent Girls

Díaz Marta , Bassols Judit , López-Bermejo Abel , de Zegher Francis , Ibáñez Lourdes

Polycystic ovary syndrome (PCOS) is a prevalent disorder in adolescent girls, commonly driven by hepato-visceral fat excess, usually presenting with hirsutism and menstrual irregularity, and often followed by subfertility and type 2 diabetes.We studied the miRNA profile of adolescent girls with PCOS, and the effects of randomized treatment with an oral contraceptive (OC) or with spironolactone-pioglitazone-metformin (SPIOMET, aiming at loss of hepato-vis...

Brown Adipose Tissue in Prepubertal Children: Associations with Sex and With the Sequence of Prenatal Growth Restraint and Postnatal Catch-up

Malpique Rita , Gallego-Escuredo Jose Miguel , Sebastiani Giorgia , Villarroya Joan , Lopez-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibanez Lourdes

Background/objectives: Individuals born small-for-gestational age (SGA), especially those who experience postnatal catch-up growth, are at increased risk for developing endocrine-metabolic abnormalities before puberty. In adults, brown adipose tissue (BAT) has been associated with protection against metabolic disorders, such as obesity, type 2 diabetes and dyslipidaemia. Here, we assessed for the first time whether BAT activation differs between prepubertal children born SGA o...

Cardiac and Vascular Assessments in Small- vs Appropriate-for-Gestational-Age Infants at Ages 1 and 2 Years

Garcia-Beltran Cristina , Sebastiani Giorgia , Pie Stella , Guerra Alberto , Lopez-Bermejo Abel , de Zegher Francis , Roses Ferran , Ibanez Lourdes

Background: Children born small-for-gestational age (SGA), especially those who experience spontaneous postnatal catch-up growth, are at increased risk for developing insulin resistance, central adiposity and cardiovascular abnormalities later in life. By age 3-6 years, SGA children have a broader aortic and carotid intima media thickness (aIMT and cIMT) which are markers of preclinical atherosclerosis.Objective: To assess longitudinally – at age 12...

Mitochondrial DNA in Placenta: Associations with Fetal Growth and Superoxide Dismutase Activity

Diaz Marta , Aragones Gemma , Sanchez-Infantes David , Bassols Judit , De Zegher Francis , Lopez-Bermejo Abel , Ibanez Lourdes

Background: Prenatal growth restraint associates with increased oxidative stress – as judged by mitochondrial dysfunction – in pregnancies complicated by preeclampsia or diabetes, but it is uncertain whether this is also the case in uncomplicated pregnancies.Objective and hypotheses: To assess the link between fetal growth restraint and placental mitochondrial dysfunction, as reflected by changes in mitochondrial DNA content and superoxide dism...

Circulating Progranulin in Human Infants: Relation to Prenatal Growth and Early Postnatal Nutrition

Díaz Marta , Mestres-Arenas Alberto , López-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibáñez Lourdes

Background: Progranulin (PGRN) displays pleiotropic biological functions including on early embryogenesis, cell proliferation, lysosomal or neuronal functioning and wound repair, and has been proposed as a biomarker for metabolic diseases. Increased PGRN levels have been reported in type 2 diabetes, nonalcoholic fatty liver disease and in preeclampsia associated to placental dysfunction. However, the ontogeny of PGRN concentrations and the potential value of P...

The proteome of circulating exosomes in appropriate- versus small-for-gestational-age infants: differentially expressed proteins at birth associate with measures of weight gain, liver fat, insulin resistance and adrenarche at age 7

Díaz Marta , Quesada Tania , Villarroya Francesc , López-Bermejo Abel , Casano Paula , de Zegher Francis , Ibáñez Lourdes

Introduction: Exosomes are extracellular vesicles whose cargo includes proteins that may influence the function of distant cells. It is unknown, however, whether there are differentially expressed proteins (DEPs) in the circulating exosomes of appropriate- vs small-for-gestational-age (AGA vs SGA) infants at birth and, if so, whether such DEPs relate to measures of endocrine-metabolic health and body composition in childhood.Subj...

Circulating GDF15 Concentrations in Girls with Low Birth Weight and Precocious Pubarche: Effects of Prolonged Metformin Treatment

Díaz Marta , Carreras-Badosa Gemma , Bassols Judit , de Zegher Francis , López- Bermejo Abel , Villarroya Francesc , Ibáñez Lourdes

Background: Low birth weight (LBW) followed by a rapid postnatal catch-up in weight predisposes individuals to a central distribution of body fat, which is reverted by metformin. Growth-and-differentiation-factor-15 (GDF15) plays an important role in the regulation of energy homeostasis, reducing food intake and lowering body weight. We aimed to assess whether GDF15 concentrations are raised by long-term metformin treatment in LBW/catch-up girls with precociou...

Placental Methylation in The IRS1 Gene is Associated with Obesity Parameters in 6 Year-Old Children Born to Mothers with Pre-Gestational Obesity

Gómez-Vilarrubla Ariadna , Mas-Parés Berta , Carreras-Badosa Gemma , Bonmatí Alexandra , Prats-Puig Anna , de-Zegher Francis , Ibañez Lourdes , López-Bermejo Abel , Bassols Judit

Background: Epigenetic alterations due to maternal obesity may contribute to an increased metabolic risk in the offspring. IRS1 has a critical role in insulin signalling and its methylation has been previously associated with body fat distribution and glucose metabolism in human adipose tissue. The relationship between IRS1 methylation in birth tissues and obesity parameters in the offspring is unknown.Objective: To iden...

Low vitamin D levels are associated with markers of metabolic syndrome in children with newly onset type 1 diabetes mellitus

Puerto-Carranza Elsa , Muriscot-Niell Liria , Carreras-Badosa Gemma , De Zegher Francis , Lourdes Ibañez , Judit Bassols , Abel López-Bermejo

Background: Low vitamin D levels are prevalent in pediatric patients with type 1 diabetes mellitus (T1DM) and are associated with increased risk for insulin resistance, type 2 diabetes mellitus and cardiovascular disease. Little is known about associations between vitamin D levels and markers of metabolic syndrome in incident T1DM in children. The aim of our study was to analyze associations between D vitamin levels and metabolic markers in newly onset T1DM pe...

Circulating Growth-and-Differentiation Factor-15 in Early Life: Relation to Prenatal and Postnatal Size

Díaz Marta , Campderrós Laura , López-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibáñez Lourdes

Background: Growth-and-differentiation factor-15 (GDF15) is a regulator of energy homeostasis, and is used as biomarker of several pathological states.Objectives: To assess longitudinally GDF15 concentrations in a cohort of infants born either appropriate- (AGA, n=70) or small-for-gestational-age (SGA, n=33), the latter known to be at increased risk for central adiposity and metabolic alteration...
