in vitro metabolic homeostatic activity of brown adipose tissue-derived exosomes

Kabataş Bilge , Eren Simge , Yıldırım Merve , Ünsal Naz , Eren Olcay

Introduction: Obesity and related metabolic diseases occur as a chronic imbalance between energy intake and energy expenditure. Due to its high metabolic activity, brown adipose tissue (BAT) has become a promising target for the development of new treatment concepts for metabolic disease. Having a high concentration of mitochondria, BAT is necessary to control the entire energy metabolism of the body. BAT consumes significant amounts of glucose and fatty acids...

Leptin Influences the Down-Regulation of UCP-1 Expression in Brown Adipose Tissue During Negative Energy Balance

Barrios Vicente , Canelles Sandra , Frago Laura M. , Chowen Julie A. , Argente Jesús

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...

Seventeen-year Observation in a Japanese Female Case of Tatton-Brown-Rahman Syndrome: An Overgrowth Syndrome with Intellectual Disability

Miyoshi Yoko , Yamamoto Keiko , Nakano Yukako , Yamamoto Kenichi , Kubota Takuo , Ozono Keiichi

Background: Advances in genetic analysis techniques has greatly contributed to recent discovery of causative genes associated with overgrowth with intellectual disability (OGID). Tatton-Brown-Rahman syndrome (TBRS) (OMIM #615879) was one of them, characterized by tall stature, a distinctive facial appearance, and intellectual disability. This syndrome was first reported in 2014. Thus, long-term clinical courses are unknown. We present our Japanese case with OGID who was diagno...

Effect of growth hormone on thermogenic and endocrine activity of brown adipose tissue and on the lipidome of children born small for gestational age

Murillo-Vallés Marta , González-López Lorena , Valls-Llussà Aina , González-Riaño Carolina , Cereijo-Tellez Rubén , Jimenez-Pavón David , Barbas Coral , Villarroya Francesc , Sánchez-Infantes David

Introduction: Brown adipose tissue (BAT) secretes molecules capable of modulating systemic metabolism. Growth hormone (GH) has hyperglycemic action, produces lipolysis and increases muscle mass. However, there are no human studies on its effect on the BAT and lipidome.Aim: To evaluate the effect of GH on BAT and lipidome in small for gestational age (SGA) patients and its relationship with adherence to treatment.<p c...

Erythropoietin Activates Classical Brown Adipose Tissue Through the Erythropoietin Receptor/STAT3 Pathway, Improving Obesity and Glucose Homeostasis in High Fat Diet-induced Obese Mice

Kodo Kazuki , Nakajima Hisakazu , Sugimoto Satoru , Itoh Ikuyo , Syota Fukuhara , Shigehara Keiichi , Nishikawa Taichiro , Mori Jun , Kosaka Kitaro , Hosoi Hajime

Background, aims and objectives: We hypothesized that classical brown adipose tissue (cBAT) could play a crucial role in the anti-obesity effects of erythropoietin (EPO). Our study highlights the mechanism in which EPO treatments could upregulate energy expenditure and improve glucose homeostasis through cBAT in obese mice fed with a high-fat diet (HFD).Method: C57BL/6J mice had been fed with HFD since the age of 4 weeks (HFD mice). We administered recom...

The Genetics of Overgrowth Syndromes

Tatton-Brown Katrina

Human growth results from an increase in cell size, cell division and amount of interstitium and is determined by the complex interplay of genetic and environmental factors. Over the last 14 years our group has been studying growth through the genetic interrogation of rare individuals presenting with syndromic overgrowth defined as an increased height and/or head circumference, compared to the age-related peer group, in combination with an intellectual disability. In the years...

Monogenic Forms of Autoimmune Diabetes: Challenges and Opportunities

Flanagan Sarah

Monogenic autoimmune diabetes results from a single highly penetrant mutation that causes autoimmunity leading to destruction of the beta-cells. Identifying monogenic autoimmune diabetes can be a challenge; early-onset type 1 diabetes (T1D) can cluster with additional autoimmune diseases due to shared polygenic risk, particularly from the HLA DR3 and DR4 alleles, and islet and other organ specific autoantibodies are present in patients with both monogenic and polygenic aetiolo...

Surgical Management of DSD: New Insights

Creighton Sarah

Traditional medical management of children born with atypical genitals includes genital surgery during early childhood. Young children cannot give informed consent and surgery is usually undertaken after a decision made by the multidisciplinary team with parental input. Long-term outcomes are uncertain and there is scanty research supporting the benefits of surgery on physical or mental well-being. Adult patients clearly describe the distress of multiple genital operations dur...

An Unusual Case of Gastrointestinal Bleeding; Expecting the Unexpected

Brooke Sarah ,

Introduction: To investigate the association between Turners Syndrome (TS) and Gastrointestingal Stromal tumours (GIST) in a single case study. There is a known link between RASopathies such as TS and solid tumours (gonadoblastoma, neuroblastoma and brain tumours,) however no known link between TS and GIST. The aim is to increase awareness into a rare condition and discuss growth hormone (GH) therapy.Case: An 11-year-old girl with backgr...

Accuracy of Glucose Sensor Estimate of HbA1c in Children with Type 1 Diabetes

Ehtisham Sarah , Adhami Sara

Introduction: Glucose sensor usage is increasing in the paediatric type 1 diabetes population. The sensor downloads can provide valuable information about glycaemic levels over a 90-day period and generate an estimated HbA1c based on the average glucose level.Aim: We aimed to test whether the sensor-estimated HbA1c over 90 days was an accurate prediction of the measured HbA1c and whether its accuracy correlated with perc...
