RAD18 transmits DNA damage signalling to elicit homologous recombination repair
To maintain genome stability, cells respond to DNA damage by activating signalling pathways that govern cell-cycle checkpoints and initiate DNA repair. Cell-cycle checkpoint controls should connect with DNA repair processes, however, exactly how such coordination occurs in vivo is largely unknown. Here we describe a new role for the E3 ligase RAD18 as the integral component in translating the d...
متن کاملActivated IGF-1R inhibits hyperglycemia-induced DNA damage and promotes DNA repair by homologous recombination.
The IGF-1R is a genetic determinant of oxidative stress and longevity. Hyperglycemia induces an exponential increase in the production of a key danger signal, reactive oxygen intermediates, which target genomic DNA. Here, we report for the first time that ligand activation of the IGF-1R prevents hyperglycemia-induced genotoxic stress and enhances DNA repair, maintaining genomic integrity and ce...
متن کاملInvolvement of Caveolin-1 in Repair of DNA Damage through Both Homologous Recombination and Non-Homologous End Joining
BACKGROUND Caveolin-1 (Cav-1), the major component of caveolae, is a 21-24 kDa integral membrane protein that interacts with a number of signaling molecules. By acting as a scaffolding protein, Cav-1 plays crucial roles in the regulation of various physiologic and patho-physiologic processes including oncogenic transformation and tumorigenesis, and tumor invasion and metastasis. METHODOLOGY/P...
متن کاملHomologous and non-homologous recombination differentially affect DNA damage repair in mice.
Ionizing radiation and interstrand DNA crosslinking compounds provide important treatments against cancer due to their extreme genotoxicity for proliferating cells. Both the efficacies of such treatments and the mutagenic potential of these agents are modulated by the ability of cells to repair the inflicted DNA damage. Here we demonstrate that homologous recombination-deficient mRAD54(-/-) mic...
متن کاملHomologous recombination repair is essential for repair of vosaroxin-induced DNA double-strand breaks
Vosaroxin (formerly voreloxin) is a first-in-class anticancer quinolone derivative that intercalates DNA and inhibits topoisomerase II, inducing site-selective double-strand breaks (DSB), G2 arrest and apoptosis. Objective responses and complete remissions were observed in phase 2 studies of vosaroxin in patients with solid and hematologic malignancies, and responses were seen in patients whose...
