Microtubules under mechanical pressure can breach dense actin networks

The paper shows microtubules can breach dense actin networks under mechanical pressure when immobilized.

Friction patterns guide actin network contraction

This study shows that friction forces between actin networks and their substrate guide contraction direction and speed, demonstrating the importance of resistive forces in cell shape control.

Recycling limits the lifetime of actin turnover

This study investigates how actin turnover is sustained with a limited monomer pool by analyzing bead motility and identifying recycling as a key factor.

The architecture of the actin network can balance the pushing forces produced by growing microtubules.

This study shows that actin network architecture modulates MTOC positioning by balancing pushing forces from growing microtubules.

Complex eukaryotic-like actin regulation systems from Asgard archaea

This paper identifies eukaryote-like actin regulation systems in Asgard archaea, showing calcium-regulated actin dynamics predating eukaryotes.
