Inhibition Of Dna Methylation In Acquired Tamoxifen-Resistant Breast Cancer: Cell Line Model And Clinical Implications, Stephanie Zimmers

Doctoral Dissertations

One out of every eight American women will develop invasive breast cancer throughout their lifetime. Approximately 70% of breast cancers are estrogen receptor alpha (ER)-positive and can therefore be treated with an anti-estrogen such as tamoxifen. Although tamoxifen treatment has been successful at reducing breast cancer death rates, nearly one-third of women treated with tamoxifen for 5 years will have disease recurrence. Therefore, it is imperative that researchers investigate the mechanisms involved in developing acquired tamoxifen resistance and identify biomarkers that are predictive of acquired resistance. DNA methylation is known to play a role in the development of breast cancer …
