- Description: The T47D/TR-1 cell line is a breast cancer cell line resistant to fulvestrant (Faslodex). This cell line has been established from T47D/S2 cells by long term treatment with 1 nM tamoxifen. T47D/TR-1 is adherent and the morphology is polygonal epithelial. T47D/TR-1 cells are oestrogen receptor (alpha) positive, they also express progesterone receptor. T47D/TR-1 are growth inhibited by fulvestrant. Antioestrogen resistance is a major problem in breast cancer treatment. Therefore, the search for new therapeutic targets and biomarkers for antiestrogen resistance is crucial. This cell line allows the study of the mechanisms involved in tamoxifen resistant breast cancer cell growth.
- Application: Determining molecular mechanisms around tamoxifen resistance
- Production details: The T47D/TR-1 cell line has been established by long term treatment of T47D/S2 cells with 1 uM tamoxifen. Clonal selection was performed in medium without tamoxifen. After growth in presence of 1 uM tamoxifen for 10 months, the growth rate was similar to the parental cells.
- Biosafety level: 1
- Cellosaurus id: CVCL_1D36
Target Details
- Target: Oestrogen receptor
Applications
- Application: Determining molecular mechanisms around tamoxifen resistance
- Application notes: T47D/TR-1 cells are ER alpha positive and express progesterone receptor, although at reduced level compared to parental T7D/S2 cells. T47D/TR-1 are growth inhibited by fulvestrant.
