The P450 Side-Chain Cleavage Isozyme Cyp11A2 Facilitates Interrenal and Gonadal Steroid Hormone Biosynthesis in Developing and Adult Zebrafish

Li Nan , Oakes James A , Storbeck Karl-Heinz , Cunliffe Vincent T , Krone Nils P

Cytochrome P450 side-chain cleavage enzyme, encoded by the CYP11A1 gene, catalyzes the first and rate-limiting step of steroid hormone biosynthesis. Previous morpholino knockdown studies described the divergent functions of the two cyp11a paralogs in zebrafish. Cyp11a1 has been suggested to be required for early development, whereas cyp11a2 is a functional equivalent of human CYP11A1 and is essential for the initiation and maintenan...

Wu Wei , Yuan Jinna , Yu Yunxian , Shen Yu , Dong Guanping , Huang Ke , Zhang Li , Fu Junfen

Ferritin is a widely used iron storage indicator. At the same time, it is also viewed as an indicator of inflammation. Chronic low-grade inflammation in obese individual, especially in the one with metabolic disorders, related to comorbidities and poor prognosis. Both hyperglycemia and iron overload can induce inflammation and result in vascular endothelial dysfunction. To study the role of ferritin in obese children and its impact on artery and liver, the present study invest...

A Novel Compound Heterozygous Mutation in the CYP11B2 Gene, Including an Intron 7 Splice Site, is Responsible for Aldosterone Synthase Deficiency Type II

Zhu Jianfang , Chen Hong , Wang Chunlin , Fang Yanlan , Kong Yuanmei , Liang Li

Objective: To investigate the clinical and molecular characteristics of a girl with aldosterone synthase deficiency type II (ASDII). We also identified the consequences of a novel splice site mutation in the CYP11B2 gene.Materials and Methods: A4-month-old girl presented with vomiting, diarrhea, and failure to thrive. Her 17α-OHP, cortisol, renin, and aldosterone were all in the normal range, and the ACTH stimulatio...

A Rare Cause of Pediatric Hypoglycemia in a Boy: A Malignat Insulinoma

Valenzise Mariella , Zirilli Giuseppina , Cannavo' Laura , Passanisi Stefano , Li Pomi Alessandra , Wasniewska Malgorzata

Insulinoma is a rare neuroendocrine tumor, usually benign, but can be life-threatening in causing hypoglycemic accidents. It presents in individuals aged between 8 and 82 years and can occur sporadically or constitute a part of multiple endocrine neoplasia type 1 (MEN-1).The nonspecific-symptoms and small size of these tumors led to difficulties of diagnosis and localization.Here we describe the case of a 11-year-old boy, who came to our attention for a ...

Clinical Features in a Patient with Turner Syndrome and Pericentric Inversion of Chromosome 9

Valenzise Mariella , Passanisi Stefano , Pomi Alessandra Li , Zirilli Giuseppina , Messina Maria Francesca , Aversa Tommaso

Turner syndrome (TS) patients are at risk for a constellation of neurocognitive and psychosocial diseases. TS is associated with an increased risk for difficulties with visual–spatial reasoning, visual–spatial memory, attention, executive functioning, motor, and math skills. Additionally, increased rates of social difficulties, anxiety, and depression are observed.Here we report the case of a 16-years-old Caucasian girl who came to our attentio...

An 11-year-old boy came to our hospital on 2019-1-23 because of "discovered hypercalcemia for 4 months."Past History: The child has a history of lupus nephritis for 2 years, and currently oral prednisone 12.5mg qd, mycophenolic acid 0.25g q12h, tacrolimus 1mg q12h for treatment. The lupus activity index was reviewed once a month due to lupus nephritis. At present, SLEDAI (lupus activity score) is 2 points, and the condition is we...

Long-Term Follow-Up Study for a Boy with Floating–Harbor Syndrome Due to a de novo Novel Heterozygous SRCAP Mutation

Ma Huamei , Zhang Jun , Guo Song , Li Yanhong , Chen Qiuli , Chen Hongshan , Du Minlian

Background: —Floating-Harbor syndrome(FHS) is a rare autosomal dominant genetic disorder associated with heterozygous mutations in SRCAP gene. The SRCAP protein activates the cAMP-response element binding protein-binding protein(CREBBP) gene that is involved in the regulation of cell growth and division.Objective: To report on long-term follow-up data of a boy with FHSMethods:...
