58th Annual ESPE

Vienna, Austria
19 Sep 2019 - 21 Sep 2019

The theme of this year’s meeting is Variety and Variation in Paediatric Endocrinology. Join us in Vienna to explore the diversity we encounter in our discipline and the care that we have to exercise when using the term “normality”. Whilst gaining an update on the latest treatments, clinical best practice and cutting edge research in the field of paediatric endocrinology.

Expression of miRNAs in Circulating Exosomes Derived from Patients with NAFLD

zhang jianwei , hu lin , huang ke , fu junfen

Nonalcoholic fatty liver disease (NAFLD),which represents the leading cause of hepatic damage worldwide,is modulated by epigenetic factors, in particular microRNAs (miRNAs), which control at post-transcriptional level many complementary target mRNA. However, the evidence for this is inconsistent. The high stability and expression of circulating exosomal miRNAs may allow their use as candidate biomarkers. For the discovery phase,exosomes were isolated from the serum of patients...

Circulating Exosomal miRNAs in Children's Nonalcoholic Steatohepatitis and the Correlation with Serum Transaminase and Uric Acid

Zhou Xuelian , Huang Ke , Ni Yan , Yuan Jinna , Liang Xinyi , Lin Hu , Dong Guanping , Fu Junfen

Background: The incidence of non-alcoholic fatty liver disease (NAFLD) in children increased rapidly paralleled with the global burden of obesity and diabetes. Although most patients are nonalcoholic fatty liver (NAFL), once progress to nonalcoholic steatohepatitis (NASH), the risk of liver fibrosis and cirrhosis increase significantly. However, the pathogenesis of NAFLD, especially how NAFL progress to NASH is still unclear. Exosomal miRNAs have attracted att...

Dysregulated Gene Expression Profile in Visceral Adipose Tissue of Juvenile Wistar Rats with Catch-Up Growth: Association with Fat Expansion and Metabolic Parameters

Lizárraga-Mollinedo Esther , Carreras-Badosa Gemma , Remesar Xavier , Xargay-Torrent Silvia , Mas-Parés Berta , Prats-Puig Anna , de Zegher Francis , Ibáñez Lourdes , López-Bermejo Abel , Bassols Judit

Background: Accelerated catch-up growth following intrauterine growth restriction increases the risk of developing visceral adiposity and metabolic syndrome. Animal models of growth restriction during gestation have been developed as a powerful tool to provide insight into the underlying molecular mechanisms thereof.Objective: To analyze the patterns of gene expression in the retroperitoneal adipose tissue of rats with i...

The Novel Phosphatidylinositol-3-Kinase (PI3K) Inhibitor Alpelisib Effectively Inhibits Growth of PTEN Haploinsufficient Lipoma Cells

Kirstein Anna , Augustin Adrien , Kiess Wieland , Garten Antje

Background and Aim: Germline mutations in the tumor suppressor gene PTEN cause PTEN Hamartoma Tumor Syndrome (PHTS). Pediatric patients frequently develop lipomas. PTEN antagonizes the growth promoting PI3K/AKT/mTOR pathway. There is no current treatment option except surgery. Treatment attempts with the mTORC1 inhibitor Rapamycin could not reverse lipoma growth. Recently, lipomas associated with a related syndrome caused by mosaic activating PI3K mutations (P...

GDF5 Increased White Adipose Tissue Thermogenesis Through p38 MAPK Signaling Pathway in Fatty Acid-binding Protein 4-GDF5 Transgenic Mice

LUO Feihong , ZHANG Wenting , PEI Zhou , WU Xiaohui

Growth differentiation factor 5 (GDF5) was reported to regulate brown adipogenesis, however, its effects on insulin sensitivity, full metabolic syndrome spectrum and the thermogenesis in subcutaneous white adipose tissue (sWAT) haven't been elucidated yet. We thus generated fatty acid-binding protein 4 (Fabp4)-GDF5 transgenic mice and showed that GDF5 transgenic mice developed a relative lean phenotype on a high-fat diet (HFD) and showed increased insulin sensitivity. Over...

Appetite Suppressing Effects of Glucoregulatory Peptides Devoid of Nausea

Doyle Robert P. , Elfers Clinton T. , Milliken Brandon T. , Sweet Ian , Roth Christian L.

Few treatments for type 2 diabetes (T2D) and obesity achieve meaningful long-term weight-loss and are often accompanied by nausea and vomiting. Thus, there is a critical need for a new generation of obesity medications that provide glycemic control with enhanced hypophagic response without nausea. Our group has developed and tested two new monomeric chimeric peptides against a novel target for obesity treatment concomitant with T2D in the form of dual agonism of the anorectic ...
