United KingdomResearchers have identified a new mechanism by which cells protect their DNA during cell division. Using advanced imaging techniques, scientists observed that ESCRT-III proteins form a protective coating around fragile DNA bridges that sometimes form when chromosomes fail to fully separate. This process is facilitated by a cellular checkpoint called the NoCut checkpoint, which delays division to allow for DNA protection. Although DNA bridges are rare in healthy cells, they have been linked to genome instability and early cancer development. The study, published in Nature Structural & Molecular Biology, highlights a previously unknown function of ESCRT proteins and opens new avenues for understanding genome stability and disease.
