Application

Application Comment Organism
molecular biology in order to develop an efficient screening method to identify viral proteins and their ability to block Jak-Stat signaling, the 2FTGH (human fibrosarcoma cells) cell assay system is used in combination with transient transfection of hepatitis C virus proteins: Using 1000 U/ml interferon and 30 mM 6-thioguanine to treat 2FTGH cells, it is established that transient protein expression in this cell system yields 39% and 0% cell survival for the positive (HPV E7) and negative controls (GFP expression) respectively. Transient expression of HCV Core-p7 results in 22% cell survival, consistent with previous reports, while expression of the HCV serine protease NS3/4a results in 54% cell survival. Furthermore, it is shown that NS3/4a inhibits phosphorylation of Stat-1 at the serine residue Hepacivirus C
