The paper shows that genotoxic stress triggers nuclear import of EXD2 to resolve RNA-DNA hybrids at stalled RNAPII, preventing transcription-replication conflicts and maintaining genome stability.

The paper shows that SMN shuttles from Cajal bodies to the nucleolus during DNA repair, aiding in nucleolar structure restoration after genotoxic stress.

This study investigates XAB2's role in Transcription-Coupled NER, showing it is remobilized after DNA damage and detached from R-loops and repair proteins.

This study identifies Nuclear Myosin I and Nuclear Beta Actin as essential for reorganizing the nucleolus after DNA repair by coordinating the displacement and re-entry of rDNA/RNAP1.
