Researchers discover that actin acts in the cell nucleus and is partly responsible for the expression of male sexual characteristics. Steroid hormones, to which belong sex hormones like estrogen or ...

Maintaining the shape of the cell, creating proper internal structure, guiding organelles and pulling chromosomes apart during mitosis are some of the important functions of the cytoskeleton. The ...

Septins belong to a family of GTP-binding proteins that is highly conserved in eukaryotes and is recognized as a novel component of the cytoskeleton. They assemble to form hetero-oligomeric complexes, ...

In the 1950s, advances in microscopy techniques allowed scientists to visualize synaptic communication between two brain cells for the first time. 1,2 However, many details beyond the general synapse ...

A Northwestern Medicine study has shed light on one of the most intricate construction projects in biology: how cells build and coordinate the internal scaffolding needed to create a healthy egg. The ...
