- 1p53 found to prevent chromothripsis by balancing transcription and replication●p53 keeps a transcription–replication balance that prevents chromothripsis
New research reported in Nature shows that the p53 protein, best known as a tumour suppressor, maintains a balance between transcription and DNA replication in cells. When this balance is disrupted, chromosomes can shatter in a catastrophic event known as chromothripsis, a recognised driver of cancer. The findings clarify how p53 guards genome integrity beyond its established roles in halting damaged cells.
