Background: Published preclinical findings from our lab (Cambridge Institute, CRUK) provided new insights into the functional cross-talk between the oestrogen receptor alpha (ERα) and the progesterone receptor (PR) in breast cancer (Mohammed et al., Nature, 2015). Addition of a PR agonist to anti-oestrogens directly modifies ERα chromatin binding and the transcriptional response in breast cancer cells, and is anti-proliferative in vitro ...
