Loop Extrusion Key to Genome Integrity and Structure

4/14/2026

Summary

Story summary

Recent studies show loop extrusion is central to chromatin organization and genome folding.
Cohesin and CCCTC-binding factor (CTCF) help form chromatin loops and topologically associating domains (TADs).
Cohesin loss disrupts loop domains, while enhancer accessibility and CTCF occupancy shape TAD architecture.
Loop extrusion dynamics are essential for maintaining genome integrity and for understanding genetic vulnerabilities and the structural organization of the human genome.
