Cell Line Description

The human sarcoma cell line HT 1080 (ECACC Catalogue number 85111505) was transfected with a vector encoding a selectable marker (guanine phosphoribosyltransferase) regulated by alpha interferon to create the 2fTGH cell line, enabling the selection of mutations in genes encoding components of the interferon signalling pathway. Chemical mutagenesis of the parent 2fTGH cell line enabled the isolation of a number of IFNg signalling mutants available from ECACC: U2A (12021502), U3A (12021503), U4A (12021504), U4C (12021505), U5A (12021506), U6A (12021507). Each contains a different mutation in the IFN signalling pathway. The 2fTGH panel provides a tool for the in vitro study and comparison of disrupted interferon signalling at multiple points across the IFN pathway. The U3A mutant cell line lacks expression of STAT1 gene product. U3A is unresponsive to interferon-alpha and interferon-gamma. U3A is partially defective in its response to double stranded RNA.
