Mutations in the metalloproteinase Zmpste24 preclude prelamin A processing and cause premature ageing. Here, de la Rosaet al.create mosaic Zmpste24 mice, revealing that cell-extrinsic effects are essential for accelerated ageing caused by prelamin A accumulation and that prelamin A reduces invasiveness of cancer cells.
