Topoisomerase II (TOP2) relieves torsional stress during transcription, DNA replication and chromosome segregation, by forming transient cleavage complex intermediates (TOP2ccs) that contain TOP2-link
Cells experience both endogenous and exogenous DNA damage daily. To maintain genome integrity and suppress tumorigenesis, individuals have evolutionarily acquired a series of repair functions, termed
Double-strand breaks (DSBs) are critical lesions in genomic DNA, and their accurate repair is essential for maintaining genome stability. The nuclear actin cytoskeleton has been implicated in homology
The UV component of sunlight is the major carcinogen involved in the etiology of skin cancers. We have studied the rare, hereditary syndrome xeroderma pigmentosum (XP), which is characterized by a ver
