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...

Extending the Phenotype and Genotype of Okur–Chung Neurodevelopmental Syndrome

Meng Zhe , Liang Liyang , Huang Siqi , Liu Zulin , Hou Lele , Zhang Lina

Background: okur-chung neurodevelopmental syndrome was confirmed to be associated with developmental disorders attributed to germline CSNK2A1 pathogenic missense variants. Only 26 cases and 22 kinds of genotype have been reported in the world so far. All reports highlighted the recognizable facial features of the syndrome as well as frequently occurring clinical features including neurodevelopmental delay, short stature, gastrointestinal, musculoskeletal and i...

A Mitophagic Response to iron Overload-Induced Oxidative Damage Associated with the PINK1/Parkin Pathway in Pancreatic Beta Cells

ZHANG Lina , LIANG Liyang , LIU Zulin , HOU Lele , OU Hui , HUANG Siqi

An increased iron overload led to a disorder in glucose metabolism. However, the mechanism through which iron overload induces beta cell death remains unknown. The present study revealed that ferric ammonium citrate treatment inhibited cell viability in vitro, induced a decline in mitochondrial membrane potential, increased oxidative stress and activated mitophagy. These effects could be alleviated by a reactive oxygen species scavenger. In summary, we demonstrated th...
