Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...
A metabolic enzyme studied for over seven decades has a hidden second function—it can unwind RNA and promote cell cycle progression, an additional function beyond its role in energy production, ...
A study shows how scientists can control cell division on demand outside of a living system. The work is a significant leap forward that can enhance our grasp of human biology and disease. A living ...

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 ...
The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...
Like all forms of cancer, lung cancer is defined by uncontrolled cell division caused by loss of physiological tissue homeostasis and failure of apoptotic cell death mechanisms. Aberrant cell ...
Researcher are now able to rebuild the switch that remodel the cytoskeleton. Images of an anaphase cytoskeleton in a dividing cell (left) and when rebuilt in vitro (right). PRC1 (green) crosslinks ...
