Cell division and PLK1: a three-stage activation process. The PLK1 protein plays a central role in cell division, and its dysregulation is associated with numerous cancers. Howeve ...

Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species ...

New research from Dana-Farber Cancer Institute scientists suggests that cyclin-dependent kinase 2 (CDK2) inhibitors, which ...

A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...

Animals and fungi predominantly use two different modes of cell division -- called open and closed mitosis, respectively. A new study has shown that different species of Ichthyosporea -- marine ...

When a human cell prepares to split into two daughter cells, it must first construct a tiny internal machine called the mitotic spindle—a structure of protein fibers that physically pulls chromosomes ...

Plants are made up of very rigid cells. Much like bricks in a wall, this feature gives them the structural support to maintain their shape and to stand upright against gravity. However, just like any ...

Researchers at the Centre for Genomic Regulation (CRG) reveal that metabolic enzymes known for their roles in energy production and nucleotide synthesis are taking on unexpected "second jobs" within ...

A cell copies all of its DNA, gears up to split in two, and then just… doesn’t. It sits there, swollen with a double genome, and nobody notices. This kind of silent failure has been observed in labs ...
