Replication collisions induced by de-repressed S-phase transcription are connected with malignant transformation of adult stem cells
Abstract
Suppression of transcription in S-phase is crucial to prevent genome instability. Zhang et al demonstrate that increase of H4K20me1 due to loss of Kmt5b cause genome instability in muscle stem cells, resulting in stem cell senescence but rhabdomyosarcoma formation when p53 is inactivated.
