Active Nucleosome Sliding, Eviction, and Reassembly Dynamics Can Regulate Chromatin Condensate Organization

– At the nucleosome scale, chromatin is an actively remodeled polymeric system whose organization is continuously reshaped by ATP-dependent remodelers that slide, evict, and reassemble nucleosomes along DNA. However, how the local structural rearrangements generated by such remodeling events influence condensate-scale...

Active Hydrodynamics Couples Polymer Organization, Shape Fluctuations, and Motility in Deformable Droplets

We study semiflexible active polymers confined within a soft, deformable droplet suspended in a fluid using dissipative particle dynamics (DPD) simulations. Extensile and contractile force dipoles along the polymer backbone generate distinct hydrodynamic flow fields that mediate effective interactions between polymer s...
