Primary immunodeficiency syndromes associated with defective DNA double-strand break repair.
Damaging DNA double-strand breaks (DNA-DSBs) following ionizing radiation (IR) exposure, potentially lead to cell death or carcinogenesis. Non-homologous end-joining (NHEJ) is the main repair pathway employed by vertebrate cells to repair such damage. Many repair pathway proteins have been identified. The creation of many diverse lymphocyte receptors to identify potential pathogens has evolved ...
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 کاملDouble 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 کاملMismatch-repair protein MSH6 is associated with Ku70 and regulates DNA double-strand break repair
MSH6, a key component of the MSH2-MSH6 complex, plays a fundamental role in the repair of mismatched DNA bases. Herein, we report that MSH6 is a novel Ku70-interacting protein identified by yeast two-hybrid screening. Ku70 and Ku86 are two key regulatory subunits of the DNA-dependent protein kinase, which plays an essential role in repair of DNA double-strand breaks (DSBs) through the non-homol...
