Abstract excerpt
The human estrogen receptor (hER) is expressed in breast cancer MCF-7 cells and plays a major role in tumorigenic processes. In this report, we demonstrate that MCF-7-specific factors can cooperate with the hER to increase its transactivation activity. We previously demonstrated that the rainbow trout ER (rtER) gene is up-regulated by the rtER protein itself, through an enhancer that contains an imperfect...
