Disease relevance of RSAD2

 

High impact information on RSAD2

  • HCMV infection causes the redistribution of the induced viperin from its normal endoplasmic reticulum association, first to the Golgi apparatus and then to cytoplasmic vacuoles containing gB and pp28 [1].
  • Expression before HCMV infection reduces viperin redistribution from the endoplasmic reticulum to the Golgi apparatus and prevents vacuolar localization, perhaps reflecting the mechanism used by HCMV to evade the antiviral function [1].
  • Stimulation of Huh-7 and HepG2 cells with IFN-alpha or -gamma revealed viperin is predominantly a type I ISG [2].
  • Furthermore, viperin expression could also be induced following transfection of Huh-7 cells with either poly(I:C) or HCV RNA [2].
  • Transient expression of viperin in cells harboring the HCV genomic replicon resulted in a significant decrease in HCV replication, suggesting that viperin has anti-HCV activity [2].
 

Biological context of RSAD2

 

Anatomical context of RSAD2

  • Viperin was expressed by endothelial cells in atherosclerotic arteries and significantly elevated in atherosclerotic compared with normal arteries [8].
  • This study tested the hypothesis that RSAD2 and IFIH1 were induced in the endometrium in a cell type-specific manner by IFNT from the conceptus during early pregnancy [6].
  • Pregnancy and interferon tau regulate RSAD2 and IFIH1 expression in the ovine uterus [6].
  • In pregnant ewes, RSAD2 and IFIH1 mRNAs increased in endometrial glands, and stroma and immune cells, but not in the luminal epithelium [6].
  • Moreover, IRF3-deficient, but not IFNalpha/betaR deficient, macrophages still induced Viperin in response to SV [4].
