This paper investigates the relationship between epigenetic marks, 3D genome organization, and the mechanical properties of chromatin. It develops a theoretical framework to infer locus-specific viscoelasticity and finds that chromatin's mechanical behavior is heterogeneous and influenced by epigenetic state. The findings suggest a mechanistic link between chromatin mechanics and processes like enhancer-promoter communication and response to cellular stress, opening avenues for experimental validation.
Key Takeaways
- •Chromatin's mechanical properties vary significantly between different genomic loci.
- •Epigenetic marks and 3D genome organization influence chromatin viscoelasticity.
- •Active marks are associated with multi-timescale relaxation and increased deformability under sustained force.
- •Promoters, enhancers, and gene bodies exhibit distinct viscoelastic behavior.
- •The findings suggest a mechanistic link between chromatin mechanics and cellular processes.
