MCF7/TAMR-4 Cell Line

Tool Details

*FOR RESEARCH USE ONLY

• Name: MCF7/TAMR-4 Cell Line
• Alternate name: MCF-7/TAMR-4 Cell Line
• Tool sub type: Continuous
• Parental cell: MCF7 S0.5
• Organism: Human
• Gender: Female
• Tissue: Breast
• Disease: Cancer
• Model: Tumour line
• Conditional: Yes
• Description: MCF7/TAMR-4 cell line is a stable tamoxifen-resistant subline. This cell line has been established in tissue culture after long term treatment with 1 uM tamoxifen. Tamoxifen (Nolvadex) is a widely used drug for hormone-dependent cancer. Tamoxifen resistance (either primary or acquired) makes oestrogen receptor-positive breast cancer much more difficult to treat. This cell line was produced from the parental cell line MCF7/S0.5, as a model cell system to study the effects of tamoxife...
• Application: Investigate signalling pathways involved in tamoxifen resistance
• Production details: The parental cell line for the MCF7/TAMR-4 cells is MCF7/S0.5, which was adapted to grow at low serum concentration in order to study the effect of estradiol and tamoxifen. MCF7/TAMR-4 has been established from a clone of cells that survived long term treatment with 1 uM tamoxifen. Tamoxifen-resistant cells are passaged continuously in presence of 1 uM tamoxifen, which is lethal for the parental MCF7/S0.5 cell line.
• Biosafety level: 1
• Additional notes: MCF7/TAMR-4 cells are oestrogen receptor positive and progesterone receptor negative. MCF7/TAMR-4 cells are growth inhibited by the pure antiestrogen fulvestrant. The oestrogen receptor is a major driver of growth of MCF7/TAMR-4 cell, ref 1. Treatment targeting the Aurora kinase A restores sensitivity to tamoxifen treatment. 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 wi...
• Recommended controls: MCF7-S0.5 parental line
• Cellosaurus id: CVCL_1D42
