Background: SGPL1 deficiency is associated with a pathological accumulation of sphingolipid intermediates and a multi-systemic condition incorporating primary adrenal insufficiency. Sphingolipid intermediates such as ceramide, sphingosine and sphingosine 1-phosphate are postulated to act as modulators of the steroidogenic pathway, often acting as second messengers altering downstream expression of steroid responsive transcriptional elements. Ceramide and sphin...

NMDA (N-Methyl-D-aspartic acid) receptors have been shown to control the timing of sexual maturation in laboratory animals. Therefore, variants in genes impacting NMDA receptor signaling might be predicted to affect human puberty. We studied an extended family with extremely delayed puberty (menarche at 16.5 - 18 years for female family members and pubertal onset at 16 years for male family members). Exome sequencing revealed a rare missense variant (F900V) in DLG2, w...

Background: The GH/IGF-I axis is involved in metabolic control and studies suggest that IGF-I deficiency and subsequent changes in IGF-I signaling in brown adipose tissue (BAT) modifies its thermogenic capacity. Food restriction reduces thermogenic capacity in BAT, while leptin stimulates thermogenesis through uncoupling protein 1 (UCP-1) induction. Leptin and IGF-I maintain important crosstalk in different tissues, but whether these two hormones interact to r...

Background and Aims: A novel bioactive peptide, mitochondrial-derived peptide (MOTS-c), has recently attracted interests as a potential prevention or therapeutic option for obesity and type 2 diabetes mellitus in mice. MOTS-c profiles have not yet been reported in type 1 diabetes (T1DM). We aimed to determine circulating MOTS-c levels in T1DM and explore the association between MOTS-c levels and various metabolic parameters.Metho...

Background: Receptor for advanced glycation end-products (RAGE) is a multiligand receptor up-regulated at sites of inflammation, especially in tissues with accelerated advanced glycation end-products formation. It is additionally stimulated by RAGE ligands S100A12 and HMGB1 released from recruited immune cells thus perpetuating the inflammatory process with a potential role in the development of type 1 diabetes as well as in development in diabetes complicatio...

Introduction: The molecular mechanisms underlying insulin resistance (IR) is complex and has not been fully elucidated yet. The experimental studies point out the role of liver-derived proteins, called hepatokines.Aims: To compare metabolic parameters and hepatokines levels in obese adolescents and healthy controls and to assess the effect of metformin therapy on plasma hepatokines levels in obese, insulin-resistant adol...

Objective: To establish INS-1 cell iron overload model, and study the effect on iron overload, proliferation, insulin secretion, mitochondria defect and oxidative stress change.Methods: INS-1 cells were cultured with different concentrations (0 as control and 5, 10, 20, 40, 80,160,320µmol/L respectively) of ferric ammonium citrate (FAC). Labile iron pool (LIP) were calculated by detecting calcein-AM fluorescence ...

Central diabetes insipidus (CDI) in children is caused by brain tumors, Langerhans cell histiocytosis (LCH), trauma, infections, or genetic abnormalities in about 60% of the cases. In the remaining 40%, CDI is idiopathic even after detailed clinical and radiological investigations. Aim of the study was to assess whether measurement of serum antibodies against human growth hormone (GH) could aid in the identification of the etiological factors for CDI.<p class="abst...

Introduction: Recombinant Growth Hormone (GH) has changed the lives of many patients with Prader-Willi Syndrome (PWS). GH treatment has beneficial effects on body composition, physical performance, cognition, psychomotor development, respiratory function and quality of life of patients with PWS. Due to the narrow therapeutic range, GH treatment is subject to strict limits. Clinicians measure serum immunoreactive Insulin-like Growth Factor 1 ('total IGF-I&#...

The survival rate of young patients with cancer has greatly improved in the last decades, in part due to the introduction of new therapeutic agents and protocols.Chemotherapy may be associated with risk of ovarian dysfunction, permanent or transient amenorrhea, symptoms of ovarian insufficiency and infertility.It has been suggested that prepubertal ovary is less susceptible to deleterious effect of chemotherapy.<p class="abstex...
