Brown Adipose Tissue in Prepubertal Children: Associations with Sex and With the Sequence of Prenatal Growth Restraint and Postnatal Catch-up

Malpique Rita , Gallego-Escuredo Jose Miguel , Sebastiani Giorgia , Villarroya Joan , Lopez-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibanez Lourdes

Background/objectives: Individuals born small-for-gestational age (SGA), especially those who experience postnatal catch-up growth, are at increased risk for developing endocrine-metabolic abnormalities before puberty. In adults, brown adipose tissue (BAT) has been associated with protection against metabolic disorders, such as obesity, type 2 diabetes and dyslipidaemia. Here, we assessed for the first time whether BAT activation differs between prepubertal children born SGA o...

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...

Insulin Dosing for Real Meals

Campbell Matthew

People with type 1 diabetes are provided guidance and structured education on adjusting their mealtime bolus insulin dose based on the carbohydrate content of the meal. However, recent research in patients using continuous subcutaneous insulin infusion (CSII) and Multiple Daily Injections (MDI) has highlighted the role of dietary fat in increasing prandial insulin requirements, particularly late into the postprandial period. The average daily amount of fat consumed as part of ...

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...

Neonatal Hyper- and Hypoglycaemia; Widening the Clinical Phenotype of Transient Neonatal Diabetes Mellitus due to 6q24 Methylation Defects

Taylor-Miller Tashunka , O'Connell Michele , Sabin Matthew

6q24 methylation defects are the most common cause of Transient Neonatal Diabetes Mellitus (TNDM). The clinical picture is one of impaired insulin secretion, small for gestational age and diabetes mellitus aged <6 months. This case illustrates the fluctuation between both hyper- and hypoglycaemia that can been seen in 6q24 methylation defects. A term, small for gestational age baby boy was noted to have hypoglycaemia (BSL 1.8 mmol/l) at 1.5 h of life which resolved with or...

Does Treatment with GnRH Analogues Affect BMI in Children with Precocious or Early Puberty?

Madhusudhana Madhavi , Willingham Linda , Gupta Sanjay , Matthew Verghese

Background: Treatment of precocious puberty with GnRH analogues is well established. But there are concerns about weight gain in patients on this treatment. There have been conflicting reports about the effect of GnRH analogues on weight.Objective and hypotheses: To assess the change in BMI in children treated with GnRH analogues within a UK Endocrine Service and to analyse the patient/parent experience of the treatment.Method: A r...
