Interaction between insulin-like growth factor binding protein-related protein 1 and transforming growth factor beta 1 in primary hepatic stellate cells

引用

Hepatobiliary & Pancreatic Diseases International 2017年第4期16卷 395-404页

作者： xiu-qing li Qian-Qian Zhang Hai-Yan Zhang Xiao-Hong Guo Hui-Qin Fan li-Xin liu Department of Gastroenterology and Hepatology The First Clinical Hospital of Shanxi Medical University Experimental Center of Science and Research The First Clinical Hospital of Shanxi Medical University Key Laboratory of Cell Physiology Provincial Department of the Ministry of EducationShanxi Medical UniversityTaiyuan 030001China

BACKGROUND: We previously showed that insulin-like growth factor binding protein-related protein 1 (IGFBPrP1) is a novel mediator in liver fibrosis. Transforming growth factor beta 1 (TGF beta 1) is known as the strongest effector of liver fibrosis. Therefore, we aimed to investigate the detailed interaction between IGFBPrP1 and TGF beta 1 in primary hepatic stellate cells (HSCs). METHODS: We overexpressed TGF beta 1 or IGFBPrP1 and inhibited TGF beta 1 expression in primary HSCs for 6, 12, 24, 48, 72, and 96 hours to investigate their interaction and observe the accompanying expressions of a-smooth muscle actin (alpha-SMA), collagen I, fibronectin, and phosphorylated-mothers against decapentaplegic homolog 2/3 (p-Smad2/3). RESULTS: We found that the adenovirus vector encoding the TGF beta 1 gene (AdTGF beta 1) induced IGFBPrP1 expression while that of alpha-SMA, collagen I, fibronectin, and TGF beta 1 increased gradually. Concomitantly, AdIGFBPrP1 upregulated TGF beta 1, alpha-SMA, collagen I, fibronectin, and p-Smad2/3 in a time-dependent manner while IGFBPrP1 expression was decreased at 96 hours. Inhibition of TGF beta 1 expression reduced the IGFBPrP1-stimulated expression of alpha-SMA, collagen I, fibronectin, and p-Smad2/3. CONCLUSIONS: These findings for the first time suggest the existence of a possible mutually regulation between IGFBPrP1 and TGF beta 1, which likely accelerates liver fibrosis progression. Furthermore, IGFBPrP1 likely participates in liver fibrosis in a TGF beta 1-depedent manner, and may act as an upstream regulatory factor of TGF beta 1 in the Smad pathway.

The pseudorabies virus(PRV)is identified as a double-helical DNA virus responsible for causing Aujeszky's disease,which results in considerable economic impacts *** enzyme tryptophanyl-tRNA synthetase 2(WARS2),a mitochondrial protein involved in protein synthesis,is recognized for its broad expression and vital role in the translation *** findings of our study showed an increase in both mRNA and protein levels of WARS2 following PRV infection in both cell cultures and animal *** WARS2 expression via RNA interference in PK-15 cells led to a reduction in PRV infection rates,whereas enhancing WARS2 expression resulted in increased infection ***,the activation of WARS2 in response to PRV was found to be reliant on the cGAS/STING/TBK1/IRF3 signaling pathway and the interferon-alpha receptor-1,highlighting its regulation via the type I interferon signaling *** analysis revealed that reducing WARS2 levels hindered PRV's ability to promote protein and lipid *** research provides novel evidence that WARS2 facilitates PRV infection through its management of protein and lipid levels,presenting new avenues for developing preventative and therapeutic measures against PRV infections.
