Approximately 30-40% of hormone receptor positive breast cancers do not respond to endocrine therapy. The recent discovery of ERβ suggests that the mechanism of action of estrogens is more complex than at first thought. Estrogens bind ERβ with affinity similar to ERα and the transcriptional activation is identical for both receptor forms. Furthermore ERα and ERβ can form biologically functional receptor heterodimers. However, little is known about ERβ expression and its role in breast cancer. …
