The awe-inspiring process of cell division can turn a fertilized egg into a baby – or a cancerous cell into a malignant tumor. With so much at stake, nature keeps it tightly controlled in a process ...
Caulobacter crescentus has emerged as a premier model for studying bacterial cell cycle regulation due to its distinctive asymmetric division, which produces two morphologically and functionally ...
Every day, our bodies perform around 330 billion cell divisions to keep us alive and functioning. These divisions rely on the cell cycle, which has been in place since the earliest bacteria. The ...

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 ...
Working with human breast and lung cells, Johns Hopkins Medicine scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many ...
“We closed a gap in our knowledge that was open for 10 years,” says Duccio Conti, a postdoc in the Musacchio group and first author of the publication. In healthy DNA replication, at first, each new ...
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 ...
