The spatial organization of transcriptional control

A Hafner, A Boettiger - Nature Reviews Genetics, 2023 - nature.com
In animals, the sequences for controlling gene expression do not concentrate just at the
transcription start site of genes, but are frequently thousands to millions of base pairs distal …

Polymers with spatial or topological constraints: Theoretical and computational results

C Micheletti, D Marenduzzo, E Orlandini - Physics Reports, 2011 - Elsevier

Polycomb repression of Hox genes involves spatial feedback but not domain compaction or phase transition

SE Murphy, AN Boettiger - Nature genetics, 2024 - nature.com
Polycomb group proteins have a critical role in silencing transcription during development. It
is commonly proposed that Polycomb-dependent changes in genome folding, which …

chromosome spatial organization. It is unclear, however, how they perform relative to each …

Polymer physics indicates chromatin folding variability across single-cells results from state degeneracy in phase separation

M Conte, L Fiorillo, S Bianco, AM Chiariello… - Nature …, 2020 - nature.com
The spatial organization of chromosomes has key functional roles, yet how chromosomes
fold remains poorly understood at the single-molecule level. Here, we employ models of …
