Liver UPR and Metabolic Consequences in an Animal Model of Intrauterine Growth Retardation (IUGR)

Deodati Annalisa , Argemi JosepMaria , Puglianiello Antonella , Germani Daniela , Ferrero Roberto , Aragon Tomas , Cianfarani Stefano

Background: Endoplasmic reticulum (ER) is the site where proteins are folded in the cell. Metabolic stress alters ER homeostasis and activates the unfolded protein response (UPR), which contributes to the development of insulin resistance and metabolic syndrome.Objective and hypotheses: To longitudinally evaluate liver UPR and its functional consequences in an animal model of IUGR followed from birth to adulthood.Method: On day 19 ...

Liver ER Stress and Intrauterine Growth Retardation in Rats

Deodati Annalisa , Argemi Josepmaria , Puglianiello Antonella , Germani Daniela , Ferrero Roberto , Aragon Tomas , Cianfarani Stefano

Background: Endoplasmic reticulum (ER) is the site where proteins are folded. Perturbation of ER homeostasis activates a set of ER-to-nucleus signaling reactions known as the unfolded protein response (UPR). Metabolic stress causes UPR activation which contributes to the development of insulin resistance and metabolic syndrome. As UPR can be activated by nutrient and oxygen starvation, we postulated that intrauterine growth restriction may trigger UPR signaling and thereby con...

Twin infants with salt-wasting: double the trouble

Graneiro Ana , Aguilar Abisad Daniela , Dantas Marina , Gonzalez Aragon Camila , Tarkoff Joshua ,

Introduction: Failure to thrive (FTT) is a common entity encountered by pediatricians. It can be caused by inadequate energy intake or “organic causes” such as inborn errors of metabolism or disorders of the endocrine system. One cause that is rarely seen is a deficiency of aldosterone.Case presentation: A set of 3-month-old monozygotic male twins presented with failure to thrive and dehydration. Initially, they were evaluated ...

17OHP levels to diagnose Non-Classic Congenital Adrenal Hyperplasia due to 21-Hydroxylase Deficiency (NC-CAH) in children with precocious pubarche

Chagas Nathália , Aragon Davi , Mermejo Livia , de Castro Margaret , Moreira Ayrton , Antonini Sonir

Background: Basal 17OHP levels to indicate an ACTH-stimulation test and post-ACTH 17OHP cut-off levels diagnosing NC-CAH vary among different guidelines.Objective: To establish the performance of basal and post-ACTH 17OHP concentrations for the NC-CAH diagnosis in children with precocious pubarche (PP).Methods: Clinical, biochemical, and molecular analysis from 202 PP patients subm...

Gonadotropin-Dependent Pubertal Disorders are Common in Patients with Virilizing Adrenocortical Tumors in Childhood

Stecchini Monica F , Braid Zilda , More Candy B , Aragon Davi C , Castro Margaret , Moreira Ayrton C , Antonini Sonir R

Background: In pediatric patients with adrenocortical tumors (ACT), morbidity and mortality rates have been extensively evaluated. However, there are almost no data on the late consequences of early exposure to high androgen levels on pubertal development and on final height (FH) in these patients.Objective: To investigate the impact of early exposure to androgen excess on gonadotropin-dependent pubertal development and on final height (...

Though up to fourteen different MODY subtypes have been so far described, there are no studies in the literature which have determined their actual frequency and prevalence in pediatric patients.Objectives: To identify the underlying molecular basis in a cohort of pediatric patients with a suspected clinical diagnosis of MODY by targeted NGS.Materials/Methods: Cohort of 60 patient fulfilling MODY c...
