Simulating topological domains in human chromosomes with a fitting-free model
C. A. Brackley, D. Michieletto, F. Mouvet +4
We discuss a polymer model for the 3D organization of human chromosomes. A chromosome is represented by a string of beads, with each bead being "colored" according to 1D bioinforma…
Extrusion without a motor: a new take on the loop extrusion model of genome organization
C. A. Brackley, J. Johnson, D. Michieletto +4
Chromatin loop extrusion is a popular model for the formation of CTCF loops and topological domains. Recent HiC data have revealed a strong bias in favour of a particular arrangeme…
Non-equilibrium chromosome looping via molecular slip-links
C. A. Brackley, J. Johnson, D. Michieletto +4
We propose a model for the formation of chromatin loops based on the diffusive sliding of a DNA-bound factor which can dimerise to form a molecular slip-link. Our slip-links mimic…
A stochastic model of supercoiling-dependent transcription
C. A. Brackley, J. Johnson, A. Bentivoglio +4
We propose a stochastic model for gene transcription coupled to DNA supercoiling, where we incorporate the experimental observation that polymerases create supercoiling as they unw…
