Bivalent chromatin domains (co-occurrence of H3K4me3 and H3K27me3) maintained by polycomb/trithorax complexes act as stimulus decoders. Upon signaling, these domains resolve toward activation or repression depending on the specific kinase/phosphatase activity and which histone methyltransferase/histone demethylase is recruited. This provides a mechanistic explanation for stimulus-specificity: the same activating signal may trigger H3K27me3 demethylation at one bivalent locus (activating transcri
Super-enhancers function as tissue-specific signal integrators containing clustered transcription factor binding sites that amplify incoming signals. Stimuli activating canonical pathways (NF-kappaB, STATs) produce convergent remodeling at typical enhancers across tissues, but super-enhancers--which contain tissue-specific configurations--drive stimulus-specific chromatin remodeling confined to particular cell types. Therapeutic targeting of super-enhancer components (BRD4, MED1) would thus prod
