| Relevance | The MCF7/AnaR-3 Cell Line was developed as a model of resistance to anti-cancer treatment with aromatase inhibitors. Third generation aromatase inhibitors (AIs) have proven to be effective treatment for estrogen receptor positive (ER+) breast cancer and are today recommended as first line endocrine therapy for postmenopausal ER+ breast cancer patients, making up the majority of breast cancer patients. However, a major problem is development of resistance against AIs. Since molecular mechanisms of AI resistance are largely undisclosed, the development of cell lines resistant to the non-steroidal AI anastrozole allows the study of the molecular basis for resistance to AIs to unravel new targets for treatment. |
| Production Details | Anastrozole-resistant cell lines were established from MCF7 cells grown in medium with 10% NCS and 10−7 M testosterone. A culture of MCF7 cells were treated with 10−7 M anastrozole for one week, trypsinized and seeded in serial dilutions in 24-well plates. Single colonies were transferred to new wells and gradually expanded in medium with anastrozole. After ~2–3 months, the isolated colonies gave rise to anastrozole-resistant cell lines, which could be grown in anastrozole-containing medium with a weekly split ratio of ~1:25. The MCF7 cell line was authenticated in January 2014 by DNA profiling using short tandem repeat loci and found to be matching the genetic profile reported for the MCF7 cell line. |
