Abstract excerpt
Breast cancers lacking estrogen receptor (ER) expression have an adverse prognosis and fail to respond to endocrine therapy. We have identified a transcriptional enhancer in the human ER gene which is differentially active in ER-positive (ER+) and ER-negative (ER-) human breast cancer cell lines. Enhancer function was mapped to a 35-bp element located from -3778 to -3744 upstream of the major human ER mRNA start...
