If cells in cell cultures grow while being treated with division-suppressing agents, their growth becomes excessive and they permanently lose their ability to divide. However, if the cells are treated ...
For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

How gene mutations disrupt cell growth and trigger cancer?
Cancer begins when mutations in specific genes override the body’s built-in controls on cell division, allowing rogue cells ...

A starting signal for cell division: Molecular switch ensures that cells divide at the right time
About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...
It's long been assumed that when a parent cell divides into two daughter cells, the parent assumes a spherical shape, which then splits into two cells that have roughly the same, round size. But a new ...
Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours - sometimes more than a day - in a ...
Researchers at the Max Delbrück Center and the University of Oxford have found that a cellular housekeeping function called autophagy—by which cell components are broken down and recycled—plays a ...
