The cytoplasm of eukaryotic cells contains an elaborate filamentous protein meshwork — the cytoskeleton — which comprises three distinct but integrated fibrous polymers: filamentous actin (F-actin; ...

Actin filaments (F-actin) are key components of sarcomeres, the basic contractile units of skeletal muscle myofibrils. A crucial step during myofibril differentiation is the sequential exchange of ...

Cells grow, divide, change their shape and move. They provide structure for the body and tissues, enter wounds to close them or chase down bacteria in our blood. The mobility of cells is a ...

Researchers have discovered that septins -- a part of the cytoskeleton -- form a barrier to the penetration of Pseudomonas aeruginosa. The process is dependent on the LecA molecule on the surface of ...

Robert Mauck, PhD, from the University of Pennsylvania, discussed how aging and differentiation alter nuclear mechanobiology at the 2014 American Society of Bone and Mineral Research Conference in ...
