Every time a white blood cell engulfs a bacterium, a neuron extends a projection to connect with a neighboring cell, or when a cancer cell forcefully squeezes through tissue to spread, the cell must ...

Cancer cells are subjected to high mechanical pressure that leads to a rupture of the nuclear envelope when migrating through narrow tissue structures, as in the case of metastasis. DNA would normally ...

Some cells, such as immune cells, are highly mobile—they constantly remodel their shape, migrate toward a wound that needs to be closed or chase down bacteria in the bloodstream. This mobility is ...

Chara corallina myosin XI (CcXI) drives the movement of actin filaments, which spontaneously form ring-like structures due to a slight curvature that leads to polar alignment. Living cells are highly ...

Researchers at Kanazawa University have published an article in eLife deciphering the actin structure-dependent preferential cooperative binding of cofilin. The actin filament is a double-stranded ...

The actin cytoskeleton in Saccharomyces cerevisiae comprises a dynamic network of filamentous structures—cables, cortical patches and the cytokinetic ring—that underpins cell shape, polarity and ...

Scientists at Université de Montréal's Institute for Research in Immunology and Cancer (IRIC) have identified a dynamic structure that forms a network on the surface of epithelial cells. Led by ...

Female fertility depends on the successful growth and maturation of eggs (oocytes) within ovarian follicles. Within these ...
