BACKGROUND Repair of DNA double-strand breaks (DSBs) by homologous recombination requires 5'-3' resection of the DSB ends. In vertebrates, DSB resection is initiated by the collaborative action of CtIP and the MRE11-RAD50-NBS1 (MRN) complex. However, how this process occurs within the context of chromatin is still not well understood. RESULTS Here we(More)
Translesion DNA synthesis (TLS) is a universal DNA damage tolerance mechanism conserved from yeast to mammals. A key event in the regulation of TLS is the monoubiquitination of proliferating cell nuclear antigen (PCNA). Extensive evidence indicates that the RAD6-RAD18 ubiquitin-conjugating/ligase complex specifically monoubiquitinates PCNA and regulates TLS(More)
OBJECTIVES Herniated discs and degenerative disc disease are major health problems worldwide. However, their pathogenesis remains obscure. This study aimed to explore the molecular mechanisms of these ailments and to identify underlying therapeutic targets.
