Actin-Driven Nanotopography Promotes Stable Integrin Adhesion Formation in Developing Tissue

Tianchi Chen, Cecilia Huertas Fernández-Espartero, Abigail Illand, Ching-Ting Tsai, Yang Yang, Benjamin Klapholz, Pierre Jouchet, Mélanie Fabre, Olivier Rossier, Bianxiao Cui, Sandrine Lévêque-Fort, Nicholas H Brown, Grégory Giannone

Morphogenesis requires building stable macromolecular structures from highly dynamic proteins. Muscles are anchored by long-lasting integrin adhesions to resist contractile force. However, the mechanisms governing integrin diffusion, immobilization, and activation within developing tissue remain…

Single-nucleosome imaging reveals principles of transient multiscale chromatin unfolding triggered by histone ADP-ribosylation at DNA lesions

Fabiola García Fernández, Catherine Chapuis, Junwoo Park, Eva Pinto, Victor Imburchia, Edoardo José Longarini, Angela Taddei, Nataliya Sokolovska, Ivan Matić, Sébastien Huet, Judith Miné-Hattab

Timely access to DNA lesions is crucial for genome integrity. This process requires profound remodeling of densely packed chromatin to establish a repair-competent architecture. However, limited resolution has made it impossible to fully understand these remodeling events. Here, combining…

HIRA defines early replication initiation zones independently of their genome compartment

T. Karagyozova, A. Gatto, A. Forest, J.-P. Quivy, M. Marti-Renom, L. Mirny, G. Almouzni

Abstract Chromatin states and 3D architecture have been used as proxy to identify replication initiation zones (IZs) in mammalian cells. While they do often correlate, their functional interconnections remain a puzzle. Here, we dissect these relationships by focusing on the histone H3.3 chaperone…

HIRA-dependent provision of histone H3.3 in active chromatin ensures genome compartmentalisation

Tina Karagyozova, Alberto Gatto, Audrey Forest, Jean-Pierre Quivy, Marc A Marti-Renom, Leonid Mirny, Geneviève Almouzni

The mammalian genome, organised into chromatin, adopts a three-dimensional (3D) folding within the cell nucleus with spatially segregated active and repressed compartments, termed A and B. However, how nucleosome deposition impacts these levels of organisation is unknown. Here, we monitored changes…
