Lipoma slice cultures as a new model to examine the effects of PI3K inhibitors on lipid accumulation

Maria Merz Lea , Kallendrusch Sonja , Winter Karsten , Klöting Nora , Krause Kerstin , Le Duc Diana , Kiess Wieland , Garten Antje

Introduction: PTEN hamartoma tumor syndrome (PHTS) is a rare genetic disorder caused by germline mutations in the tumor suppressor gene Phosphatase and tensin homologue (PTEN), a negative regulator of the phosphoinositide-3 kinase (PI3K)/AKT/ mechanistic target of rapamycin (mTOR) pathway. Children with PHTS frequently develop adipose tissue overgrowth, so called lipomas that can lead to loss of organ function due to displacing lipoma growth. Currently, except...

Diagnostic value of soluble LEPR levels in the serum of patients with disease-causing biallelic LEPR variants

Zorn Stefanie , Tews Daniel , von Schnurbein Julia , Flehmig Bertram , Pridzun Lutz , Wabitsch Martin , Malene IV , Chantana Yay , Khun Leang Chhun , Ban Manet , Tyla Martin , Ngee Lek

Introduction: The soluble leptin receptor (sLR) is the main binding protein of leptin in the serum. It reflects the amount of membrane-bound leptin receptors (LEPR) as the sLR is produced by proteolytic cleavage of the extracellular domain of membrane-bound LEPR. Low sLR but high leptin levels were measured in patients with severe obesity. In patients with monogenic obesity caused by biallelic LEPR variants, sLR levels were found to be either undetect...

Leptin treatment affects adipose progenitor cells physiology

Jasaszwili Mariami , Fuchs Lasse , Richter Sandy , Kirstein Anna , Kiess Wieland , Le Duc Diana , Garten Antje

Introduction: Leptin, an adipokine secreted mainly by adipose tissue, is a regulator of energy balance acting through central mechanisms on the hypothalamus. However, leptin has many functions regulating e.g., immune system and reproduction. Leptin exerts its biological effects through its receptor, the expression of which has been demonstrated in several tissues. There are several leptin receptor isoforms, but activation of only one of them, the long form, re...

Serum leptin concentrations in a pooled cohort of 6.105 children and adolescents: Reference values as a function of dependence on sex, age, pubertal stage and BMI-SDS

Brandt Stephanie , Vogel Mandy , Kratzsch Jürgen , Tews Daniel , Pridzun Lutz , Flehmig Bertram , B Ranke Michael , Körner Antje , Kiess Wieland , F Blum Werner , Wabitsch Martin

Background: Current reference values for leptin in childhood and adolescence are presented separately for girls and boys, and as a function of age without considering the variability of fat mass. This complicates the interpretation of measured serum leptin concentrations since fat mass is the major determinant of circulating leptin concentrations. To fill this gap, we aimed at pooling existing data (age, BMI, sex, tanner stage (TS), serum leptin concentrations...

Karabouta Zacharoula , Simeoforidou Elpida , Georgoulia Konstandina , Koniari Eleni , Bisbinas Alexia , Chrousos George

Introduction: Familial hypercholesterolaemia(FH) is a genetic disorder affecting approximately 1 in 250 people, resulting in high levels of low-density lipoprotein Cholesterol(LDL-C), increasing the likelihood of developing cardiovascular disease(CVD) at a younger age. Lipoprotein (a)(Lp(a)) is another risk factor for atherosclerosis, elevated in 20-25% of people and 90% genetically determined, only slightly reduced by diet, exercise and medication.<p clas...

Early onset obesity due to Melanocortin 4 receptor (MC4R) defect; Successful treatment with Semaglutide

Ramya Gokul Pon , Apperley Louise , Parkinson Jennifer , Seniappan Senthil

Introduction: Childhood obesity is a growing concern worldwide, and it has been linked to several nutritional and genetic factors. In some patients, monogenic causes can be identified, which are due to single gene mutations in specific pathways related to appetite regulation. One of the most common monogenic causes of obesity is heterozygous mutations in Melanocortin 4 receptor (MC4R), with a prevalence ranging from 2% to 6% in juvenile-onset obesity. We repor...

Background: 16p11.2 microdeletion is most common chromosomal anomaly associated with syndromic obesity. The presence of a large number of flanking segmental duplications/low-copy repeat sequences with a high degree of sequence identity in the short arm of chromosome 16 (16p) leads to recurrent deletions and duplications as a consequence of non-allelic homologous recombination. A recurrent 600kb microdeletion is one of the most frequent genomic imbalances in 16...

Gonzalez Diego , Rodriguez Roberto , Garibay-Nieto Nayely , Villanueva-Ortega Eréndira , Aguilar-Cuarto Karina , Pedraza Karen , Fuentes Zendy , Ruiz Alejandra , María Hernandez Ana , Prado Edith , Ruiz Arturo

Body Mass Index (BMI) has a high association with body fat percentage and direct association with a higher degree of comorbidities. Categorizing patients only by the degree of obesity, as has been done over time, restricts the possibility of detecting and giving timely treatment to other aspects. The Edmonton Obesity Staging System for Pediatrics (EOSS-P) has been proposed as a tool to categorize obesity not only by BMI, but also by assessing metabolic complications, functiona...

Introduction: Prader-Willi Syndrome (PWS) is characterized by severe neonatal hypotonia and feeding difficulty with subsequent hyperphagia, hypogonadism, and short stature. PWS has a prevalence of 1 in 10,000-30,000. Obesity-related complications occur from early childhood onwards. Liraglutide is a glucagon-like peptide-1 (GLP-1) analog that reduces appetite and body weight and improves glycemic control. Scarcity of oxytocin-producing neurons in the hypothalam...
