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 ...

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 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 ...

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 ...

The formation of the branched actin networks is essential for cell polarity, but it remains unclear how the debranching activity of actin filaments contributes to this process. Here, we showed that an ...

Cancer cells are subjected to high mechanical pressure that leads to a rupture of the nuclear envelope when migrating through narrow tissue structures, as in the case of metastasis. DNA would normally ...

Cell migration is a multistep process essential to various physiological functions, including immune cell movement and embryonic development, as well as pathological conditions like tumor metastasis.

Cell division is the process of a cell splitting into two genetically identical daughter cells. The actin protein seen in this video is essential for successful cell division. While actin has several ...

Investigators from the laboratory of Derek Walsh, Ph.D., professor of Microbiology-Immunology, have discovered how human cytomegalovirus rewires intracellular mechanisms to control the movement of the ...
