Insulin and epidermal growth factor receptor family members share parallel activation mechanisms

Kathryn M. Ferguson, Chun Hu, Mark A. Lemmon

Protein Science > 29 > 6 > 1331 - 1344

Insulin receptor (IR) and the epidermal growth factor receptor (EGFR) were the first receptor tyrosine kinases (RTKs) to be studied in detail. Both are important clinical targets—in diabetes and cancer, respectively. They have unique extracellular domain compositions among RTKs, but share a common module with two ligand‐binding leucine‐rich‐repeat (LRR)‐like domains connected by a flexible cysteine‐rich...

Effect of Vitamin D Supplementation on Vascular Function and Inflammation in Patients with Chronic Kidney Disease: A Controversial Issue

Chun Hu, Xiaoyan Wu

Therapeutic Apheresis and Dialysis > 24 > 3 > 265 - 274

Vitamin D deficiency is common in patients with CKD and is associated with vascular dysfunction and inflammation. In recent years, some randomized controlled trials have revealed the effect of vitamin D supplementation on vascular function and inflammation in CKD patients, but the results are inconsistent. Thus, in light of the controversy, we performed a systematic review and meta‐analysis of the...

Chun Hu, Xiaoyan Wu

International Urology and Nephrology > 2019 > 51 > 12 > 2227-2233

The prevalence of asymptomatic HUA is increasing year after year. HUA is a risk factor for the occurrence and development of renal diseases. However, the role of urate-lowering therapy in asymptomatic HUA complicated by renal damage is still controversial. In some experiments, the treatment of asymptomatic HUA complicated by renal damage may delay the progression of kidney damage. In addition, there...

Shu-Ping Shan, Shi-Hua Chen, Chun Hu, Ren-Zhong Zhuang

International Journal of Theoretical Physics > 2019 > 58 > 11 > 3702-3710

Using Pekar variational method, we studied the influence of Rashba effect on the bound magnetopolaron in an anisotropic quantum dot. The expression of the ground state energy of the bound magnetopolaron is obtained by theoretical derivation. Due to the influence of the Rashba effect, the ground state energy of the bound magnetopolaron splits into two branches. This phenomenon fully demonstrates that...
