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 ...

Interleukin 6 (IL6) signaling has been associated with an aggressive and metastatic phenotype in multiple solid tumors including breast cancer, but its mechanism of action in mediating tumor progression and treatment response is not clear. By exploiting a clinically relevant intraductal xenograft model of estrogen receptor positive (ER+) breast cancer, we demonstrate that IL6 increases both primary tumor growth and distant metastases. By integrating pre-clinical models and cli...
