- The oestrogen receptor alpha (ESR1) is a transcription factor that potentiates the response to diverse stimuli, including oestrogen and growth factors, in various tissue types. Its recruitment to the DNA is directly regulated by the chromatin landscape, inclusive of chromatin compaction and epigenetic modifications. In this review we discuss our current understanding of the interplay between ESR1 signaling and the chromatin landscape. We present how the chromatin landscape primes the lineage-specific response and contributes to stimuli-specific signaling. Finally, we discuss recent efforts to decipher the relationship between genetic and epigenetic as it relates to ESR1 signaling in breast cancer.
