  • Description: Endocrine therapy of breast cancer has been applied widely and proven to be effective. However, in many instances endocrine treatments ultimately fail due to the development of an estrogen-independent therapy resistant phenotype. To elucidate the molecular mechanism underlying this endocrine therapy failure, the laboratory of Lambert Dorssers applied different genetic screens to identify the main genes conferring estrogen independence. Out of 15 candidate BCAR genes, several including BCAR1, BCAR3, AKT1, AKT2, BCAR4, GRB7, EGFR, HRAS, PDGFRA, PDGFRB and RAF1 were shown to directly underlie estrogen independence by transfection into the ZR-75-1 breast cancer cell line resulting in a panel of 16 cell lines (Cat No 154621-154635, 154642) These cell lines are 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.
