Introduction: We previously reported that miglitol, an alpha-glucosidase inhibitor (α-GI), increases energy expenditure by enhancing β3-adrenergic signaling of brown adipose tissue (BAT) and reduces obesity in dietary-induced obese mice (S Sugimoto et al, at the 9th joint meeting of Pediatric Endocrinology, 2013) (Nutrition & Metabolism). However, this report did not describe the mechanism by which miglitol enhances β3-adrenergic signaling....

Background: Recently, ghrelin has attracted attention as a hormone connected with appetite. The relationship between ghrelin genetic polymorphisms and obesity has been analyzed in adults, but the influence of these SNPs on obesity in children is uncertain.Objective: We perform SNP analysis of the ghrelin gene and examine its relationship with the childhood obesity.Population: We analyzed 35 patients (27 boys, eight girls) treated i...

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

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...

Background: Brown adipose tissue (BAT) was thought to exist only from birth to infancy and not in adults. However, it has recently been found to be present in adults as well, drawing significant attention as a target for anti-obesity drugs due to its characteristic of energy expenditure independent of exercise. ACE2 converts Angiotensin II (AngII) to Angiotensin 1-7 and antagonizes the ACE/AngII system through Mas receptor. We have previously reported that adm...

The Collapse of the BDNF/POMC System in the Hypothalamus is Responsible for the Extreme Obesity with Hyperphagia Observed in Female Heterozygous MeCP2 Null Mice

Objective and hypotheses: The aim was to elucidate the mechanism underlying the extreme obesity observed in female heterozygous MeCP2 null mice fed a high-fat diet.Method: We examined the molecular biology and physiology of female heterozygous MeCP2 null mice (Mecp2tm1.1Bird/J, MeCP2+/− mice) fed a high-fat diet (HFD) for 12 weeks since 4 weeks of age using analytical tools. C57/BL6 mice were used as controls.<p class="abs...
