Studies led by cell biologist Thomas Maresca at the University of Massachusetts Amherst are revealing new details about a molecular surveillance system that helps detect and correct errors in cell division that can lead to cell death or human diseases. Findings are reported in the Journal of Cell Biology.

Overall, this well-orchestrated process prevents serious problems such as aneuploidy, that is, too many chromosomes in daughter cells. Aneuploidy in somatic or body cells leads to cell death and is a hallmark of most cancer cells. But in eggs or sperm, it leads to serious birth defects and miscarriages.
