The Relationship between Steriod Receptors and Aromatase in the Mouse Brain

Yilmaz Bertan , Zhao Hong , Brooks David , Fenkci Veysel , Yenicesu Gonca , Attar Erkut , Bulun Serdar

Background: Local oestrogen production in the brain regulates critical functions including neuronal development, gonadotropin secretion and sexual behaviour. In the mouse brain, a 36 kb distal promoter (l.f) regulates the Cyp19a1 gene that encodes aromatase, the key enzyme for oestrogen biosynthesis. In vitro, promoter l.f interacts with oestrogen receptor alpha (Esr1) and Progesterone receptor (Pgr) to mediate Cyp19a1 mRNA expressi...

Functional MRI of a Female Teenager of Prada-Willi Syndrome Complicated with Mosaic Turner Syndrome

Wang Wei , Li Juan , Sun Ying , You Hui , Ma Chao , Song Hongmei , Zhao Weigang

Background: A patient with both Prader-Willi syndrome and mosaic Turner syndrome is extremely rare. We performed fMRI and euglycaemic-hyperinsulinaemic clamp test for her.Case presentation: A 17-yr-old girl was diagnosed as Prader-Willi syndrome by her clinical investigations including poor feeding in infancy, hyperphagia, developmental delay, mental disorders, behavior problems, thin upper lip, almond-shaped eyes, acromicria and genital hypoplasia. Mate...

In Search for New Monogenic Diabetes Genes: PCBD1

Simaite Deimante , Kofent Julia , Gong Maolian , Ruschendorf Franz , Jia Shiqi , Arn Pamela , Bentler Kristi , Ellaway Carolyn , Kuhnen Peter , Hoffmann Georg , Blau Nenad , Spagnoli Francesca , Hubner Norbert , Raile Klemens

Background: Mutations in more than 20 genes are described to cause monogenic diabetes. Nevertheless, numerous families with diabetes of unknown ethology and suspected genetic defect have no molecular diagnosis. This not only impedes our understanding of disease mechanisms but also prevents from predicting the clinical course of the patients and applying the pathogenesis-oriented treatment.Objective: To identify novel gene(s), causing monogenic adolescent...

Determinants of Vitamin D Levels in Children, Adolescents, and Young Adults with Juvenile Idiopathic Arthritis

Stagi Stefano , Capirchio Laura , Marino Achille , Bertini Federico , Seminara Salvatore , de Martino Maurizio , Falcini Fernanda

Background: 25-Hydroxyvitamin D (25(OH)D) deficiency is reported to be common in patients with rheumatoid arthritis and associated with disease activity, physical disability, and cardiometabolic intermediates; data in patients with juvenile idiopathic arthritis (JIA) are inconsistent.Objective and hypotheses: To assess serum 25(OH)D in children, adolescents, and young adults with JIA, and to identify the risk factors for vitamin D deficiency in JIA patie...

Exploring the growth curves of 248 Chinese patients aged 0-3 years with salt-wasting 21-hydroxylase deficiency

Li Yingying , Fan Xin , Wang Yirou , Zhao Xiu , Pan Lili , Yu Yuting , Gong Gong Chunxiu , Su Zhe

Background: To construct the growth curves of body length and weight for Chinese patients from birth to 3 years with salt-wasting 21-hydroxylase deficiency (SW 21-OHD), changes in body mass index (BMI) will also be described, so as to explore the growth pattern of these special patients and guide the monitoring of early growth.Methods: The body length and weight data of SW 21-OHD patients aged 0-3 years who visited in 4 ...

Correlation Between Initial Treatment Effect of Recombinant Human GH and Exon 3 Polymorphism of GH Receptor in Chinese GH Deficiency Children

Zheng Zhangqian , Cao Linfeng , Pei Zhou , Luo Feihong , Zhi Dijing , Zhao Zhuhui , Ye Rong , Cheng Ruoqian , Li Xiaojing

Objective and hypotheses: To investigate the frequency distribution of exon 3 deleted (d3-GHR) genetic polymorphism of GH receptor (GHR) in GH deficient (GHD) Chinese children and to explore the correlation between the growth promoting effects of recombinant human GH (rhGH) and exon 3 genetic polymorphism of GHR in GHD children.Method: 111 GHD (excluded small for gestational age) children were treated with rhGH (0.20 mg/kg per week) for 6 months. The bod...

Growth results after GH treatment of children with juvenile idiopathic arthritis

Noumi Mustapha , Akretche Nora , Boukari Rachida

Introduction: Short stature is a very common complication of juvenile idiopathic arthritis (JIA). Chronic inflammation, long-term corticosteroid therapy, hepatic impairment and malnutrition can reduce the biological effects of IGF-1 and GH. Growth hormone (GH) treatment may improve height growth outcomes in patients with severe juvenile idiopathic arthritis (JIA). The aim of the study was to assess the response to growth hormone (GH) treatment in patients with...

Auxological Features in Patients with Juvenile Idiopathic Arthritis Treated with Biologic Therapy Preliminary Study Data

Marino Achille , Cimaz Rolando , Giani Teresa , Simonini Gabriele , Stagi Stefano

Background: Juvenile idiopathic arthritis (JIA) is a heterogeneous group of diseases associated with an increase of inflammatory cytokines that may to influence child growth. However this is already known, to date auxological data published of JIA patients during biologic treatment are incomplete and very heterogeneous.Objective and hypotheses: To evaluate the auxological features in a selected cohort of patients with JIA treated with biologic drugs....

HDAC4 Mutations Cause Diabetes and Induce β-Cell FoxO1 Nuclear Exclusion

Gong Maolian , Yu Yong , Vuralli Dogus , Fröhler Sebastian , Kühnen Peter , Du Bois Philipp , Zhang Jingjing , Hussain Khalid , Fielitz Jens , Jia Shiqi , Chen Wei , Raile Klemens

Background: Studying patients with rare Mendelian diabetes has highlighted molecular mechanisms regulating β-cell pathophysiology. Previous, experimental studies have shown that Class IIa histone deacetylases (HDAC4, 5, 7, and 9) modulate mammalian pancreatic endocrine cell differentiation, function and finally glucose homeostasis.Methods: We performed exome sequencing in one adolescent boy with non-autoimmune di...

Background: Mutations in genes involved in insulin secretion or regulation of β cell identity cause both persistent neonatal diabetes (PND) and hyperinsulinemic hypoglycemia of infancy (HHI) pinpointing shared pathogenic mechanisms. KCNQ1 encodes a potassium channel protein, Kv7.1, which is a voltage-gated potassium channel expressed in cardiac tissue, pancreas, inner ear neurons, and other tissues. Variants in or nearby to KCNQ1 were linked t...
