Steroid hormones, such as oestrogen, mediate their effects via activation of oestrogen regulated genes using nuclear receptors. Selective oestrogen receptor modulators (SERMs), such as Tamoxifen, are used to treat oestrogen responsive breast cancers, hctioning to act as oestrogen antagonists, preventing the oestrogen receptor biding DNA and blocking gene expression. However, Tamoxifen has been identified as an oestrogen agonist in other tissues which can often lead to secondary tumors in the years following the treatment. Identification of the genomic regions where SERMs can act as oestrogen agonists can possibly lead to the development of gene targeted therapies or other alternatives to …
