Title Transcription-coupled changes in genomic region proximities during transcriptional bursting.
Journal Sci Adv
Abstract The orchestration of our genes heavily relies on coordinated communication between enhancers and promoters, yet the mechanisms behind this dynamic interplay during active transcription remain unclear. Here, we investigated enhancer-promoter (E-P) interactions in relation to transcriptional bursting in mouse embryonic stem cells using sequential DNA/RNA/immunofluorescence-fluorescence in situ hybridization analyses. Our data reveal that the active state of specific genes is characterized by specific proximities between different genomic regions and the accumulation of transcriptional regulatory factors. Mathematical simulations suggest that an increase in local viscosity could potentially contribute to stabilizing the duration of these E-P proximities. Our study provides insights into the association among E-P proximity, protein accumulation, and transcriptional dynamics, paving the way for a more nuanced understanding of gene-specific regulatory mechanisms.
