Breast cancer is widely and effectively treated with endocrine treatment. However, in many cases the tumours will eventually progress into an estrogen-independent and therapy-resistant phenotype.
Seven genes including AKT1, AKT2, BCAR1, BCAR2, BCAR3, EGFR2 and GRB7 have been shown to directly underlie estrogen independence in human breast cancer cells. This cell line is part of a panel of 16 cell lines (Cat No 154621-154635, 154642) which have been transfected with these genes, plus the parental (Cat No 154547).
This cell line is a powerful tool for studying the molecular and cellular mechanisms of breast tumour progression, therapy resistance and to test the effectiveness of novel drugs to combat different modes of anti-estrogen insensitivity
|Cells were established by infection of ZR-75-1 cells with cell free supernatant of NT/HERc virus producing psi-2 cells for 17h in the presence of 8uM polybrene. Clones were selected in media containing 1mg/ml G418 and expanded in estradiol containing media.

|Recommended Growing Conditions
|RPMI 1640 medium supplemented with 10% heat-inactivated bovine serum (RBCS) and 1 nM 17β-estradiol
|The cell line is resistant to Geneticin, which may be included in the culture medium to ensure that the expression vector is retained by the cells.
