  • Tool type: Cell Lines

  • Cancer type: Mammary ductal carcinoma, estrogen independent
  • Disease: Cancer
  • Description: 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. Somatic cell fusion was used to generate this cell line in order to elucidate the molecular mechanisms underlaying endocrine therapy failure. Using this method revealed that tamoxifen resistance co-segregated with only 1 or 2 of the integration loci present in the tamoxifen-resistant donor cell line, designated the first breast cancer anti-estrogen resistance locus (BCAR1) This cell line is part of a panel of 3 somatic hybrids (Cat No 154639-154641) plus the parental (Cat 154620). This cell line is a powerful tool for studying the molecular and cellular mechanisms of breast tumour progression and therapy resistance.
