Longitudinal growth is driven by endochondral ossification at the growth plate, where chondrocytes undergo a well-organized cellular differentiation process from stem-like progenitors to rapidly-proliferating transit-amplifying cells and to hypertrophic chondrocytes. Numerous recent studies have demonstrated that epigenetic modifications play a crucial role in human development and childhood growth. For example, Brachydactyly mental retardation syndrome (BDMR) is caused by hap...

Background: Brown adipose tissue metabolism is of remarkable pathophysiological interest, because it could be a target for therapies for obesity and metabolic syndrome. Irisin (Ir), recently identified adipomyokine is essential in a white-to-brown fatty tissue transdifferentiation, and mediates some of the positive influences on metabolic disorders through increase of energy expenditure. The exact regulation of Ir secretion and action is unknown but positive associations of ci...

Background: Recent guidelines suggest that NCCAH subjects stop their glucocorticoid therapy after achieving adult height. However, these guidelines do not differentiate between genotype groups within the NCCAH population.Aim: Compare ACTH stimulated cortisol and 17-hydroxyprogesterone (17OHP) levels, and the rate of partial cortisol insufficiency in NCCAH subjects carrying one mild and one severe (mild/severe) mutation v...

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...

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...

Introduction: The presence of ZnT8 (zinc transporter 8) has been described on the surface of beta pancreatic cells in type 1 diabetic patients and the ZnT8 Ab (zinc transporter-8 autoantibody) has been recently established as a new marker of this autoimmune disease. There are studies demonstrating that ZnT8 may be of importance in some other endocrine cell types. In our study we wanted to verify the presence of ZnT8 in thyroid cells of children and adolescents...

We report a case of a child who presented with huge pericardial effusion complicated to cardiac tamponade secondary to primary hypothyroidism. Due to the severity of cardiac tamponade, pericardiocentesis was performed to relieve the compression effect. The child improved with Levothyroxine treatment.Hypothyroidism is a rare cause of pericardial effusion in children. If the pericardial effusion increases in volume, cardiac tamponade with clinical...

Background: The new adipokine/myokine meteorin-like (Metrnl) has been proposed to be of interest for obesity and metabolic disease through its potential role for brown/beige fat thermogenesis and macrophage activation in mice. METRNL was reported to be expressed in white adipose tissue (AT) and upregulated during adipogenesis and by exercise and.Aims: In this study we analysed the expression of METRNL during human adipogenesis and its regulation...

Recently, we identified Neuritin 1 (NRN1) as preferentially expressed in human white compared to brown adipocyte progenitor cells. In mice, Nrn1 deficiency leads to a reduction in body weight, indicating that it might regulate body weight. In this study, we aim to address the function of NRN1 regarding adipocyte metabolism in vitro and in vivo. We used human SGBS preadipocytes as an in vitro model system. NRN1-deficient cells were generated using len...

Aim: 12,13-dihydroxy-9Z-octadecenoic acid (12,13-diHOME) is a lipokine secreted from brown adipose tissue, and it is shown to have positive effects on dyslipidemia. Acute exercise have been shown to lead to an increase in its secretion. It was aimed to investigate the relation of 12,13-diHOME with obesity, exercise and dyslipidemia for the first time in the adolescent age group.Methods: This is a prospective study includ...
