This study shows that cohesin loading at enhancers does not significantly contribute to genome folding or long-range transcriptional control, as inhibiting cohesin recruitment near enhancers reduces target promoter transcription.

The paper shows that CTCF depletion disrupts chromatin hub formation but not enhancer-promoter interactions, which still drive gene expression during differentiation.

This study shows that the Mediator complex is essential for enhancer-promoter interactions, as its depletion reduces interaction frequencies and gene expression, while increasing CTCF-binding site interactions and altering Cohesin distribution.

The paper analyzes sub-kilobase chromatin topology to show that nano-scale regulatory interactions depend on CTCF but not cohesin, and that cohesin affects longer-range enhancer-promoter interactions.
