Every time a muscle fiber forms, a single cell must perform one of the most dramatic architectural transformations in biology. A myoblast — a committed muscle precursor cell — has to abandon div ...

Increase in Ultraviolet-B flux from the Sun has the potential to alter the protein in mammals. Rabbit muscle was processed and filtered to extract G-actin, which was tested for its protein ...

Actin filaments are protein fibers that make up the internal skeleton of the cell. As active elements of our cells, actin filaments support the cell's fusion, movement and are involved in many other ...

The transport of molecules along the cell's skeleton plays a role in cancer metastasis, researchers show. Metastases occur when cancer cells leave a primary tumor and spread throughout the body. For ...
