An electron microscopy study revealed key details of actin filaments, which are essential structural elements of cells and muscles. Actin filaments -- protein structures critical to living movement ...

Researchers have demonstrated that an actin scaffold stabilizes the cell nucleus upon mechanical stress. This protective ...

The three-dimensional structure of a protein involved in the assembly of actin filaments could help to settle a long-standing scientific debate about the regulation of cytoskeletal organization. The ...

Actin filaments - protein structures critical to living movement from single cells to animals - have long been known to have polarity associated with their physical characteristics, with growing ...

Actin filaments are part of the cell skeleton and essential for stability and motility. They form a network that dynamically builds up and gets broken down by the addition or detachment of building ...

The actin cytoskeleton has the unique capability of producing pushing forces at the leading edge of motile cells without the implication of molecular motors. This phenomenon has been extensively ...

Thin, flexible protein strands called actin filaments act like bones for our cells and are critical for its movement. Supercomputer simulations have helped solve a decades-old mystery of how actin ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 116, No. 10 (March 5, 2019), pp. 4265-4274 (10 pages) We used cryo-electron microscopy (cryo-EM) to reconstruct ...

Metastases occur when cancer cells leave a primary tumor and spread throughout the body. For this, they have to break connections with neighboring cells and migrate to other tissues. Both processes ...

Huntington's disease is a rare genetic disorder and a representative neurodegenerative disease, characterized by loss of ...
