Double strand break repair.
DNA double-strand breaks (DSBs) are the most dangerous form of DNA damage and can lead to death, mutation, or malignant transformation. Mammalian cells use three major pathways to repair DSBs: homologous recombination (HR), classical nonhomologous end joining (C-NHEJ), and alternative end joining (A-NHEJ). Cells choose among the pathways by interactions of the pathways with CtIP and 53BP1. HR i...
متن کاملDNA Double-Strand Break Repair
ownloade C regulates a myriad of genes controlling cell proliferation, metabolism, differentiation, and apoptosis. lso controls the expression of DNA double-strand break (DSB) repair genes and therefore may be a ial target for anticancer therapy to sensitize cancer cells to DNA damage or prevent genetic instability. report, we studied whether MYC binds to DSB repair gene promoters and modulates...
متن کاملDNA double-strand break repair
The integrity of genomic DNA is crucial for its function. And yet, DNA in living cells is inherently unstable. It is subject to mechanical stress and to many types of chemical modification that may lead to breaks in one or both strands of the double helix. Within the cell, reactive oxygen species generated by normal respiratory metabolism can cause double-strand breaks, as can stalled DNA repli...
متن کاملThe Pathways of Double-Strand Break Repair
1.1 Induction and repair of double-strand breaks (DSBs) in the DNA DNA encodes and transmits genetic information into the progeny of cells and organisms. As a result, processes associated with DNA replication, repair and recombination are at the center of biological research. Although the double-stranded nature of the DNA molecule is not a requirement for its replication or transcription, it is...
متن کاملDrosophila ATR in double-strand break repair.
The ability of a cell to sense and respond to DNA damage is essential for genome stability. An important aspect of the response is arrest of the cell cycle, presumably to allow time for repair. Ataxia telangiectasia mutated (ATM) and ATR are essential for such cell-cycle control, but some observations suggest that they also play a direct role in DNA repair. The Drosophila ortholog of ATR, MEI-4...
