Identification of Death Ligand TNF-Related Apoptosis-Inducing Ligand as a Potent Mitogen in Human Preadipocytes

Funcke Jan-Bernd , Zoller Verena , El Hay Muad Abd , Debatin Klaus-Michael , Wabitsch Martin , Fischer-Posovszky Pamela

Background: Adipose tissue is an important endocrine organ. Its secretion profile is robustly changed in the context of obesity fueling the development of comorbidities such as insulin resistance, diabetes mellitus type 2, and atherosclerosis. We have recently shown that the adipose tissue expression of the death ligand TNF-Related Apoptosis-Inducing Ligand TRAIL and its receptors is upregulated in obesity.Objective and Hypotheses: In this project, we in...

Functional Characterization of a Novel Heterozygous Point Mutation in the Human Glucocorticoid Receptor Gene Causing Primary Generalized Glucocorticoid Resistance

Nicolaides Nicolas C , Vlachakis Dimitris , Sertedaki Amalia , Kossida Sophia , Chrousos George P , Charmandari Evangelia

Background: Primary generalized glucocorticoid resistance (PGGR) or Chrousos syndrome is a rare familial or sporadic condition caused by mutations in the hGR gene, which reduce tissue sensitivity to glucocorticoids. A new case of PGGR caused by a novel heterozygous point mutation in the hGR gene, which resulted in threonine (T) to isoleucine (I) substitution at amino acid position 556 in the ligand-binding domain of the receptor, was recently reported in a patient with an adre...

Butyrate Stimulates GH Secretion From Rat Anterior Pituitary Cells Via the G-Protein-Coupled Receptors GPR41 and 43

Miletta Maria Consolata , Petkovic Vibor , Eble Andree , Ammann Roland , Fluck Christa E , Mullis Primus E

Background: Butyrate is a short-chain fatty acid closely related to the ketone body β-hydroxybutyrate (BHB) considered as the major source of energy during prolonged exercise. During fasting, when the liver switches to fatty acid oxidation, a rise in serum GH occurs concomitantly with the accumulation of BHB and short chain fatty acids (SCFA) acetate, propionate and butyrate. Interactions between GH, ketone body and SCFA during the metabolic adaptation to fasting are poor...

A Novel NR5A1 Mutation with Preserved Fertility

Yagi Hiroko , Takagi Masaki , Hasegawa Yukihiro , Igarashi Maki , Kon Masafumi , Fukami Maki

Background: The common phenotype caused by NR5A1 mutations of 46,XY is gonadal dysgenesis without adrenal deficiency. Preserved fertility of the affected males was described in two patients with different mutations. No functional analysis of these two mutations has been done. Here we report brothers with isolated hypospadias who carries a novel heterozygous mutation of c.910G>A, E304K in NR5A1 gene. Their asymptomatic father carries the same nucleotide ch...

Nonclassic Lipoid Adrenal Hyperplasia with R272C STAR Mutation: a Case Report

Miyoshi Tatsuya , Takagi Masaki , Hasegawa Yukihiro

Background: The StAR protein is crucial for the transportation of cholesterol to the mitochondria, where it is converted to pregnenolone. Complete loss of StAR protein function impairs adrenal and gonadal steroidogenesis since the fetal period, called classic lipoid adrenal hyperplasia (CLAH). Nonclassic lipoid adrenal hyperplasia (NCLAH) is a recently recognized disorder, with partial StAR protein function, and several mutations causing NCLAH have been reported.<p class="...

Ternary Complex Formation and IGFBP3 Proteolytic Activity During Childhood: Age-Dependent Changes

Renes Judith S , van Doorn Jaap , Hokken-Koelega Anita C S

Background: IGF1 is mainly sequestered in a 150 kDa ternary complex with IGFBP3 and the acid-labile subunit (ALS). Dissociation of IGF1 from the ternary complex is in part regulated by proteolysis of IGFBP3, which reduces its affinity for IGF1. Short children born SGA have lower IGF1 and IGFBP3 levels compared to healthy peers.Objective and hypotheses: To determine complex formation in healthy normal statured children, and assess variables influencing co...

ALS Deficiency due to a Novel and Two Already Described IGFALS Gene Mutations in an Unusual Non Consanguineous Family: Two Compound Heterozygous (Father and Son) and Two Heterozygous Carriers (Brother and Mother)

Scaglia Paula , Keselman Ana , Martucci Lucia , Karabatas Liliana , Ballerini Maria Gabriela , Domene Sabina , Johanna Acosta , Jasper Hector , Domene Horacio

Introduction: Complete ALS deficiency (ALS-D), caused by inactivating mutations in both IGFALS gene alleles, presents severe IGF1 and IGFBP3 deficiencies associated to moderate growth retardation.Aim: To characterize the molecular defect in a family where the index case and his father presented short stature and IGF1 and IGFBP3 deficiencies.Methods: IGF1, IGFBP3, and GH serum levels were determined by CLIA, ALS by ELISA an...

The Effect of the Environmental Factors on Growth Pattern of Turkish Children Having the Same Genetic Origin

Yuca Sevil Ari , Cesur Yasar , Kurtoglu Selim , Mazicioglu Mumtaz Mustafa , Cimbek Emine Ayca

Background: Childhood is a dynamic process with continuous growth and development. Growth charts are essential for the assessment of children’s health status. Standards previously established in children aged 6–18 years, according to percentile curves are used in Turkey.Objective and hypotheses: To determine the effect of different environmental factors on growth of children with the same genetic origin. We investigated the parameters of growth...

Incidence of Diabetes Mellitus and Associated Complications Among Children: Results from Azerbaijan Diabetes Registry 1997–2007

Ahmadov Gunduz

Background: Diabetes prevalence is increasing globally, and Azerbaijan is no exception. Poorly controlled diabetes is associated with increased long-term micro-vascular and macro-vascular complication risk, leading to an increased morbidity and mortality.Objective and hypotheses: The purpose of this study was to estimate incidence of diabetes mellitus (DM) among children aged 0–18 years and to assess growth, glycaemic control, complications, risk fa...

Prevalence of Secondary Diabetes and Related Factors in China Hospitalized Children

Yu-Chuan Li , Bing-yan Cao , Chun-xiu Gong , Xue-jun Liang

Background: Secondary diabetes in children, often rising from the treatment of the primary disease. However, not enough attention has been paid. We analyze the cases of secondary diabetes in children identified from 2002 to 2010 in our hospital for the frequency and clinical features, so as to gain a better understanding of the disease.Objective and hypotheses: To investigate the prevalence and association factors of secondary diabetes in Chinese hospita...
