Lay Summary

Approximately 75% of breast cancers express estrogen receptor (ER). Endocrine therapy targeting the ER pathway is effective, but resistance leading to disease progression and metastasis is common and clinically challenging. A better understanding of the mechanisms of endocrine resistance and metastasis is needed to develop new therapies and predictive biomarkers to improve patient outcome. FOXA1 is a protein that regulates ER activity on gene expression. We have recently shown that aberrant activation of FOXA1 signaling leads to endocrine resistance and metastasis. Our findings are supported by recent clinical observations showing FOXA1 gene amplification in a significant subset (~20%) of ER...
