Product description: The 2fTGH-U3A Cell Line is part of a panel of IFNy pathway mutant fibrosarcoma cell lines isolated by chemical mutagenesis of IFNy insensitive reporter cells derived from HT1080 cells. Knockout genes have been identified and span multiple members of the IFMy pathway. These cell lines are be useful for the in vitro study and comparison of disrupted interferon signalling at multiple points across the IFN pathway. The following cell lines are part of the group of IFN signalling mutants: U4C, U2A, U3A, 2FTGH, U6A, U5A. Each containing a different mutation in the IFN signalling pathway. MCF7/TAMR-7 cells are oestrogen receptor positive and progesterone receptor negative. MCF7/TAMR-7 cells are growth inhibited by the pure antioestrogen fulvestrant. The oestrogen receptor is a major driver of growth of MCF7/TAMR-7 cell.The TAMR lines were established from the MCF7/S0.5 cell line, which was adapted to grow with 0.5% fetal calf serum in phenol red containing DMEM/F12 medium. Treatment with tamoxifen was started in passage 351. Few colonies of cells survived the treatment and after 28 days of tamoxifen treatment, tamoxifen was omitted from the medium for 22 days. After 19 passages without tamoxifen (passage 372) the cells underwent a second treatment with tamoxifen which initially reduced cell growth rate, but around 390-400 the growth rate of the tamoxifen resistant cell lines was close to the growth rate of the parental MCF7/S0.5 cells.
Conditional: Yes
Production details: Human; HT1080 human sarcoma cell lines transfected with a vector encoding a selectable marker regulated by interferon to create the 2fTGH cell line, enabling selection of mutations in genes encoding components of the interferon signalling pathway. Chemical mutagenesis of the 2fTGH cell line enabled isolation of 10 IFNg signalling mutants.
