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 ...

The cytoskeleton of eukaryotic cells is made of filamentous proteins, and it provides mechanical support to the cell and its cytoplasmic constituents. All cytoskeletons consist of three major classes ...

Transcription of DNA into RNA is an extraordinarily complex, highly regulated process. Gene transcription depends on a complex molecular machine consisting of more than 100 proteins. It is turned on ...

No one has yet created a fully functioning artificial cell. But a research team at Aarhus University has taken a step in that direction: ...

A microscopic flaw in the brain’s cellular scaffolding can shape brain size for life.

The dynamic processes that occur during the growth of actin, via polymerization, and the breakdown of actin both play significant roles in cellular mechanisms like migration and adhesion. Due to the ...

Researchers have visualized at the molecular level how formins bind to the ends of actin filaments. This allowed them to uncover how formins mediate the addition of new actin molecules to a growing ...

Researchers used miniature human brains grown in the lab to uncover why certain genetic mutations lead to abnormally small ...

Our skin and mucous membranes are protected by epithelial cells. This barrier tissue performs its function thanks to specialized structures called junctions. They ensure cell cohesion and regulate ...

Scientists at Aarhus University have developed nanomotors inspired by the bacterium Listeria monocytogenes and placed them inside artificial cells. The nanomotors drive the formation of internal ...

Epithelial cells defend human skin and mucous membranes. Specialized structures known as “junctions” enable this “barrier” tissue to carry out its role. They control interactions between cells and ...

Scientists at Children’s Medical Research Institute (CMRI) have made a major discovery about cancer cells. This new understanding could help make chemotherapy work better, reduce side effects, and ...
