Super-enhancers are established through the interactions of several enhancers and
a large number of proteins, including transcription factors and co-regulators;
however, the formation of these interactions is poorly understood. By
re-analysing previously published estrogen receptor alpha (ER?) ChIP-seq data
sets derived from the MCF-7 cell line, we observed that in the absence of
stimulation, future super-enhancers are represented by one or a few transcription
factor binding event(s) and these extraordinary enhancers possess a response
element largely specific to the ER? dimer. Upon hormonal stimulation, these
primary binding sites are surrounded by a large amount of ER? and the critical
components of active enhancers, such as P300 and MED1, and together with
neighbouring sites bound by newly recruited ER?, they generate the functional
super-enhancers. To further validate the role of canonical elements in
super-enhancer formation, we investigated some additional signal-dependent
transcription factors, confirming that certain, distinguished binding elements
have a general organizer function. These results suggest that certain
signal-specific transcription factors guide super-enhancer formation upon binding
to strong response elements. These findings may reshape the current understanding
of how these regulatory units assemble, highlighting the involvement of DNA
elements instead of protein-protein interactions.
