Traction Forces Control Cell-Edge Dynamics and Mediate Distance Sensitivity during Cell Polarization

Alexander Verkhovskiy, Franck Claude Raynaud, Alicia Carine Bornert, Zeno Messi

Traction forces are generated by cellular actin-myosin system and transmitted to the environment through adhesions. They are believed to drive cell motion, shape changes, and extracellular matrix remodeling [1 -3] . However, most of the traction force anal ...

Conditional Selection of Genomic Alterations Dictates Cancer Evolution and Oncogenic Dependencies

Elisa Oricchio, Mohammad Sadegh Saghafinia, Elena Battistello, Daniele Tavernari, Stephanie Jocelyne Sungalee, Franck Claude Raynaud, Giovanni Ciriello, Marco Mina, Titouan Laessle

Cancer evolves through the emergence and selection of molecular alterations. Cancer genome profiling has revealed that specific events are more or less likely to be co-selected, suggesting that the selection of one event depends on the others. However, the ...

Minimal model for spontaneous cell polarization and edge activity in oscillating, rotating and migrating cells

Jean-Jacques Meister, Chiara Gabella, Alexander Verkhovskiy, Franck Claude Raynaud, Alicia Carine Bornert, Mark Etienne Ambühl

How cells break symmetry and organize activity at their edges to move directionally is a fundamental question in cell biology. Physical models of cell motility commonly incorporate gradients of regulatory proteins and/or feedback from the motion itself to ...

Intercellular ultrafast Ca2+ wave in vascular smooth muscle cells: numerical and experimental study

Jean-Jacques Meister, Niccolo Piacentini, Franck Claude Raynaud, Jairo Camilo Quijano Perez

Vascular smooth muscle cells exhibit intercellular Ca2+ waves in response to local mechanical or KCl stimulation. Recently, a new type of intercellular Ca2+ wave was observed in vitro in a linear arrangement of smooth muscle cells. The intercellular wave w ...

Systemic Risk in Energy Derivative Markets: A Graph-Theory Analysis

Franck Claude Raynaud

This article uses graph theory to provide novel evidence regarding market integration, a favorable condition for systemic risk to appear in. Relying on daily futures returns covering a 12-year period, we examine cross- and inter-market linkages, both withi ...
