Tool Details

  • Tool name: ZR-75-1 HRAS [ZR-HRAS pool B] cell line
  • Alternate names: HRas Proto-Oncogene, GTPase; Transforming Protein P21
  • Tool type: Cell Lines
  • Tool sub-type: Continuous
  • Parental cell line: ZR-75-1
  • Organism: Human
  • Tissue: Breast
  • Cancer type: Mammary ductal carcinoma, estrogen independent
  • Disease: Cancer
  • Model: Cancer Model
  • 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. 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
  • Research area: Cancer ; Drug Discovery & Development
  • Production details: Expression constructs with HRAS were transfected into ZR-75-1 cells using FuGENE 6 and selected with G418. After selection for G418 resistance colonies were expanded

  • For Research Use Only
