Dynamic rewiring of super-enhancers shapes condition-specific genome regulation

Super-enhancer constituents rewire more extensively than typical enhancers during differentiation, reshaping enhancer–promoter chromatin contact networks in PMA-induced K562, h9 cardiomyocytes, and primary foreskin keratinocytes.

• Why it matters: It remains unclear how super-enhancer and typical enhancer network positions change across cell-state transitions, despite maps of 3D contacts and prior graph-based findings about their static connectivity.
• What they did: The study built enhancer–promoter networks from high-resolution Hi-C and applied network-based analyses, integrating Hi-C and HiChIP data across three differentiation systems to track modular structure and remodeling.
• The result: Differentiation mainly reshapes network structure via enhancer turnover, and persistent super-enhancer constituents preferentially connect to promoters driving identity-defining programs, while typical enhancers link to general metabolic and stress-response loci.
