Albert , Dattani Mehul T. ,

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...

Background: Aromatase inhibitors (AIs) have been suggested to slow down estrogen-dependent skeletal maturation in pubertal boys with short stature. In the literature, few studies evaluate the efficacy and safety of AIs in boys with growth hormone deficiency (GHD). Objective: To evaluate the auxologic effects and short-term laboratory profiles of combined AI and rhGH therapy in adolescent males with GHD.Subjects and Methods:</stro...

microRNA-27a - a strand specific regulator of adipogenesis and adipocyte function

Roos Julian , Wu Hang , Pula Taner , Tews Daniel , Wabitsch Martin , Debatin Klaus-Michael , Fischer-Posovszky Pamela

MicroRNAs (miRNAs) are small non-coding RNA molecules and play an important role in the post-transcriptional regulation of gene expression and thereby influence important cellular functions. In adipocytes, miRNAs regulate key processes such as differentiation, inflammation, metabolism, and adipokine secretion. Recently, we found that miR-27a is upregulated under proinflammatory conditions in human adipocytes. Thus, our goal was to better understand the function of miR-27a in a...

NBAS Gene Mutation Causes Insulin-Dependent Diabetes Mellitus in a Patient with a Multisystem Disorder Consisting Immunodeficiency and Extremely Short Stature

Giatropoulou Sofia , Konig Rainer , Wudy Stefan A. , Speckmann Carsten , Kury Patrick , Fischer-Zirnsak Bjorn , Clemens Kamrath

We report the case of a 19 years old male patient suffering from a multisystem disease involving of the skeleton, connective tissue, immune system, brain and endocrine system due to compound-heterozygote mutations in the NBAS (Neuroblastoma amplified sequence) gene (c.5741G>A [p.(Arg1914His)]; c.6565_6566insT [p.(Glu2189Valfs*7)]), detected using whole-exome-sequencing. He has an immunodeficiency including decreased CD4+T-cells, B-cells and NK-cells with expanded ...

Metabolic Phenotype of Human Adipocytes Overexpressing UCP1

Tews Daniel , Pula Taner , Funcke Jan-Bernd , Wabitsch Martin , Fischer-Posovszky Pamela

Background: Functional studies on uncoupling protein 1 (UCP1) are important to identify potential pharmacological targets which interfere with energy metabolism. However, current cell models of human origin are scarce due to limited tissue availability. In this study, we generated human preadipocytes and adipocytes with an overexpression of UCP1 and studied the metabolic function of these cells.Methods: Human Simpson-Golabi-Behmel syndrome (SGBS) cells w...

Resveratrol Inhibits Inflammation-Induced Production of Cytokines in Human Adipocytes

Zagotta Ivana , Killian Alexandra , Haas Jennifer , Kietzmann Thomas , Debatin Klaus-Michael , Wabitsch Martin , Fischer-Posovszky Pamela

Background: Upon excessive expansion, adipose tissue is infiltrated by macrophages and shows increased production of inflammatory cytokines. This chronic low grade inflammation of adipose tissue is involved in the pathogenesis of insulin resistance. A supplementation with resveratrol can reverse the metabolic disturbances of human obesity, in part by mimicking the effects of caloric restriction.Objective and Hypotheses: We hypothesized that the beneficia...

Fetal Anogenital Distance (AGD) by Ultrasonography: a Marker of Early Androgen Exposure in utero?

Fischer Margit Bistrup , Scheel Lone , Sundberg Karin , Juul Anders , Hagen Casper P ,

Background: The anogenital distance (AGD) is defined as the distance from the anus to genital tubercle. AGD is an established method for sex determination of pups in rodents, and in animal studies, AGD is strongly affected by androgen exposure during fetal life. In accordance, human studies have reported reduced postnatal AGD following prenatal exposure to anti-androgenic agents, suggesting AGD to be a sensitive postnatal read out of in utero exposure...

Glucocorticoid-mediated leptin secretion from human adipocytes is dependent on glucose availability

Tews Daniel , Brandt Stephanie , von Schnurbein Julia , Fischer-Posovszky Pamela , Wabitsch Martin

Background: Leptin is produced by adipocytes and regulates central hunger and satiety sensation. While the central leptin effects are well understood, little is known about the regulation of peripheral leptin production. Clinical data demonstrate that leptin levels are rapidly declining upon fasting, suggesting that leptin secretion is acutely regulated by nutrient availability. Although it has been previously shown that leptin secretion is under control by gl...

Introduction: Pediatric obesity is a global public health problem that is associated with severe cardiometabolic consequences. Weight management interventions focusing on lifestyles have shown some promising results, but attrition rates are often high and reasons for dropout are poorly understood.Objectives: We aimed toestimate the prevalence, and identify the determinants of attrition among pediatric participants in the first year of a 2-year lifestyle ...
