What is the relationship between promoter and super enhancer transcriptional program?

  • Super-enhancer-driven transcriptional programmes and promoter-proximal transcription factor-associated gene expression have an unclear relationship.
  • However, their different genomic occupancy raises the possibility of a method for independent and separate gene control.
  • In multiple myeloma, we investigated the transcriptional and functional interactions between E2F transcription factors and BET transcriptional co-activators.
  • Scientists discovered that multiple myeloma cells depend on the transcription factor E2F1 and its heterodimerization partner DP1.
  • Global chromatin analysis revealed separate regulatory axes for E2F and BETs, with BETs predominately located at enhancer-regulated tissue-specific genes and E2F primarily localised to active gene promoters of growth and/or proliferation genes.
