Chromatin bridges are strands of incompletely segregated DNA connecting the anaphase poles or daughter nuclei. If unresolved, chromatin bridges can break in cytokinesis leading to micronuclei ...

Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan. Instead, order emerges on ...

Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan.

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 ...

Chara corallina myosin XI (CcXI) drives the movement of actin filaments, which spontaneously form ring-like structures due to a slight curvature that leads to polar alignment.

In all eukaryotic cells, actin protein assembles to form a network of thin filaments that spread throughout the cell. The actin filaments give the cell its structure, enable the cell to move, and ...

The researchers experimented on a Drosophila – fruit fly – model, examining the F-actin in the brains of naturally aging animals. They compared the brains of young, middle-aged, and late-age flies and ...

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 ...

Every time our body encounters a new disease-causing agent, a crucial defence system called adaptive immunity comes into play. T cells, the top agents in this system, survey the internal environment ...
