Introduction: Wolfram syndrome (WS) is a rare autosomal recessive disorder characterized by the association of early-onset, insulin-dependent diabetes mellitus (DM), diabetes insipidus, deafness, and progressive optic atrophy. The disease is caused by mutations of wfs1 located on 4p16 encoding peptide that is called wolframin. Wolframin is a component of the endoplasmic reticulum (ER) membrane. It is considered that mutant Wolframin might cause increased misfolded and...

A 12-year 8-month-old girl visited our hospital due to short stature. Her height was 130.7 cm (−3.6SD), and her weight was 42 kg (−0.24 SD). She had cubitus valgus and breast budding (Tanner stage II) without a webbed neck, congenital heart anomaly, exophthalmos, or goiter. Laboratory results in serum were as follows: Ca 10.3 mg/dL, LH11.7 mIU/mL, FSH37.7 mIU/mL, estrogen 18.6 pg/mL, IGF-1 304 ng/mL, and bone age 12 years and 0 months. All other laboratory findings...

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...

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...

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...
