Effect of Sonic Hedgehog Signalling on Regulation the Expression of 11β-HSD2 in the Placenta

Zou Chao Chun , Wu Xiao Hui , Xiong Wen-Yi

Objective: Excessive exposure to glucocorticoids (GCs) during gestation period not only causes fetal growth retardation but also increases the risk of adult metabolic diseases. 11 Beta-hydroxysteroid dehydrogenase (11β-HSD2) is a kind of glucocorticoid metabolic enzymes, which plays a role to the placental GCs barrier during gestation period. The aim of this study is to investigate the effect and mechanism of sonic hedgehog (Shh) signalling on regulation the expression of...

Clinical and Cytogenetic Analysis on Two Chinese Familial Cases of Prader-Willi Syndrome with Multiple Affected Patients

Yunqi Chao , Chaochun Zou

Prader–Willi Syndrome (PWS [MIM 176270]) is a rare neurogenetic disorder mapping to the chromosome 15q11-q13 domain, which results from the genetic and epigenetic function deficiency of genomic imprinting of paternal alleles. It is characterized by neonatal hypotonia with following childhood obesity, hyperphagia, developmental delay and short stature, hypogonadism, cognitive impairment, and behavioral problems. PWS is generally sporadic that occurs in about 1 in 10 000 to...

Dysregulated adipose tissue expansion and impaired adipogenesis in Prader-Willi syndrome children before obesity-onset

Chao Yunqi , Zou Chaochun

Objective: Prader-Willi syndrome (PWS) is a rare genetic imprinting disorder resulting from the expression loss of genes on the paternally inherited chromosome 15q11-13. Early-onset life-thriving obesity represents the PWS clinical hallmarks. The noncoding RNA gene SNORD116 within the minimal PWS genetic lesion plays a critical role in the pathogenesis of the syndrome. Despite advancements in understanding the genetic basis for PWS, the pathophysiology of obes...

Gut microbiota, a potential cause of higher insulin sensitivity in children with Prader-Willi syndrome

Zhong Mian-Ling , Cai Yu-Qing , Tang Yan-Fei , Dai Yang-Li , Jiang Yong-Hui , Ni Yan , Zou Chao-Chun

Keywords: Prader-Willi syndrome; Gut microbiota; Insulin sensitivity; Metagenomics sequencing; Obesity.Aim: Obesity is the main driving factor for comorbidities in Prader-Willi syndrome (PWS) patients due to overeating behaviors. The gut microbiota has been implicated in the aetiology of obesity and associated comorbidities. The purpose of the present study is to characterize the fecal microbiota in Chinese patients with...

NIPBL is Required for Postnatal Growth and Neural Development

zou chaochun , wu xiaohui

Cornelia de Lange syndrome (CdLS) is a multisystem organ developmental disorder characterized by growth and cognitive deficits and premature aging, caused by mutations in genes coding for the cohesin complex. CdLS cells presented with gene expression dysregulation, genomic instability, decreased energy production and oxidative stress. Variants in the cohesin loading factor Nipped-B-like (NIPBL) gene can be identified in approximately 70% of cases and the ...

Perinatal Features of Prader-Willi Syndrome: A Chinese Cohort

Yang Lili , Zou Chaochun

Background: Prader-Willi syndrome (PWS) is a rare complex genetic disorder caused by an absence of expression of imprinted genes on the paternally derived chromosome 15q11-q13 region. This study aimed to characterize the perinatal features in a cohort of Chinese individuals with PWS.Methods: We analyzed anonymous data of 134 patients from the PWS Registry in China. Perinatal and neonatal presentations were analyzed, and ...

The phenotypic spectrum of Kenny-Caffey type 2: a case series and literature review

Chen Xuefei , Zou Chaochun

Context: Kenny–Caffey syndrome (KCS) is a rare condition characterized by proportionate short stature, cortical thickening and medullary stenosis of tubular bones, delayed closure of the anterior fontanelle, ocular and dental anomalies, and variable hypocalcemia due to hypoparathyroidism. KCS is classified into two types according to its clinical features and inheritance pattern. KCS Type 2 (KCS2) is caused by mutations in FAM111A and is distinguished fr...
