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 ...

Scientists at Feinberg are reshaping scientific understanding of the cell's tiniest components—structures once thought to be ...

The actin cytoskeleton is a dynamic network made up of actin polymers and associated actin binding proteins. The actin cytoskeleton was originally isolated as a component of the actomyosin complex in ...

Bacteria and archaea use protein filament systems to organize cellular processes in time and space. Filaments can act as static scaffolds or as dynamic motors. In some cases, these filament systems ...

Most cell structures are not visible to the naked eye without using stains for visualization. The stains used in these images highlight how cell biologists use tricks to “see the invisible.” Invite ...

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 researcher at the UPV/EHU-University of the Basque Country has participated in the study into the impairment of the dynamics of spines that receive information from other neurons A researcher at the ...

Steroid hormones, to which belong sex hormones like estrogen or testosterone, are important signaling molecules and are responsible among other things for controlling female and male phenotypic sex ...
