Novel Uncoupling Protein 1 Expression in White Adipocytes of Subcutaneous Abdominal Adipose Tissue in Children and Adolescents: A Protective Mechanism for Metabolic Equilibrium?

Karvela Alexia , Avgeri Aikaterini , Vlotinou Eleni D , Georgiou George , Papachristou Dionysios J , Spiliotis Bessie E

Background: Morbid childhood obesity predisposes to metabolic disorders such as diabetes type 2. In mice, heat-producing ‘brown-like’ (beige) adipocytes can suppress weight gain and metabolic disease through the action of uncoupling protein 1 (UCP1) localized in the mitochondria.Objective and hypotheses: To study the expression of UCP1 in the adipose tissue of lean&obese children and adolescents.Method: Paraffin embed...

Ontogeny of FGF21 in the Human: Implications for Metabolic Health

Villarroya Francesc

Background: FGF21 is a hormonal factor with powerful anti-diabetic and anti-obesity properties in adults\. Studies in rodent models indicated that hepatic FGF21 expression and blood FGF21 levels are strongly induced after birth in response to fat provided by milk ingestion. Moreover, preliminary data indicate that FGF21 is present in maternal milk.Objective and hypotheses: Our objective is to determine, using human samples and pre-clinical experimental m...

A Novel Melanocortin-4-Receptor Gene Mutation Associated with Early Onset Severe Obesity

Toumba Meropi , Shammas Christos , Neocleous Vassos , Phelan Marie , Skordis Nicos , Phylactou Leonidas , Mantzoros Christos

Background: The melanocortin-4-receptor gene (MC4R) is a key regulator for appetite and satiety. MC4R mutations account for 6–8% of severe obesity in children with variable expression and penetrance.Case presentation: A 3-year-old girl is presented with severe early onset and progressive obesity. She was born full-term with appropriate of gestational age weight by non-consanguineous parents. She had normal psychomotor milestones an...

Use of the 100,000 Genomes Project to identify the molecular basis of rare endocrine disorders within a tertiary paediatric endocrinology centre

M McGlacken-Byrne Sinead , Gregory Louise , Roberts Rowenna , Wakeling Emma , Katugampola Harshini , T Dattani Mehul

Introduction: The UK 100,000 Genomes Project (100KGP) recently investigated the genetic basis of rare disease using whole genome sequencing. The genetic aetiology of most rare paediatric endocrine disease remains unexplained.Methods: Children with genetically unexplained rare endocrine disease attending a subspecialist paediatric endocrinology clinic underwent whole genome sequencing as part of the 100KGP. Parental DNA w...

Glucose alterations, insulin resistance, hypertension, and activation of the renin-aldosterone system are strictly associated in pediatric obesity

Antoniotti Valentina , Amore Martina , Bellone Simonetta , Ricotti Roberta , De Grandi Roberta , Caputo Marina , Spadaccini Daniele , Mancioppi Valentina , Aimaretti Gianluca , Prodam Flavia

Background: The increase of global childhood obesity has led to an increase of associated co-morbidities also at a young age. The pro-inflammatory state and insulin resistance are two master regulators of several complications, including hypertension and pre-diabetes frequently connected in a complex crosstalk.Aim: To evaluate the relationship between glucose alterations and blood pressure and the pathogenetic involvemen...

Pten knockout in osteoprogenitor cells leads to loss of adipose tissue

Kolbig Florentien , Lorenz Judith , Roth Lisa , Lindhorst Andreas , Thor Doreen , Le Duc Diana , Gericke Martin , Kiess Wieland , Klöting Nora , Krause Kerstin , Garten Antje

Background and Aim: Pediatric patients with germline mutations in the phosphatase and tensin homolog (Pten) gene frequently develop aberrant adipose tissue growth called lipomas. In severe cases, recurrent lipoma formation can have adverse effects on organ function and quality of life. Due to the lack of understanding the basis of lipoma development, no systemic treatment options are available. We therefore aimed to characterize an already described lipoma bea...

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...

Early-Onset Obesity and Adrenal Insufficiency Associated with a Homozygous POMC Mutation

Meloni Antonella , Casini Maria Rosaria , Del Giudice Emanuele Miraglia , Boccone Loredana

Background: Isolated hypocortisolism due to ACTH deficiency is a rare condition that can be caused by mutations in the gene encoding pro-opiomelanocortin (POMC). POMC is the precursor to bioactive peptides (ACTH, β-endorphin, and α-β-γ-MSH). Mutations that inactive POMC typically result in secondary adrenal insufficiency, severe obesity and red hair; fewer than 50 affected individuals have been reported in the literature.Case presenta...

Turner Syndrome with Breast Development: Case Report

Park Sung Won , Cho Sung Yoon , Kim Jinsup , Huh Rimm , Kim Su Jin , Jin Dong-kyu

Introduction: Turner syndrome (TS) is caused by monosomy or structural abnormalities of the X chromosome, with a prevalence of out 1/2500 females live birth. Most important clinical features of TS are short stature and gonadal failure. Approximately one third of girls with TS may undergo spontaneous puberty. Here we report a case of a variant TS with breast development.Case report: A 9-year-old girl was referred to our paediatric endocrinology outpatient...
