Epidemiological data suggests a correlation between phytoestrogen consumption and a reduced incidence of breast cancer. Current in vitro data is ambiguous, suggesting differential proliferative effects of phytoestrogens depending on ER expression status and exogenous estradiol levels. This study aims to characterise the growth inhibitory effects of the isoflavones genistein and daidzein using a panel of human breast cancer cell lines.Flow cytometry revealed low leve...

Hormone dependent breast cancer is preferentially treated with Tamoxifen (TAM), an Estrogen Receptor antagonist. Although the initial response to TAM is tumour regression the majority of patients eventually relapse. Understanding the mechanisms that contribute to this resistant phenotype may influence the success of patient response to TAM and prevention of recurrence.A role for ER coactivator and corepressor proteins has been suggested to contribute to...
