DNA 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 کاملA p53 Oscillator Model of DNA Break Repair Control
The transcription factor p53 is an important regulator of cell fate. Mutations in p53 gene are associated with many cancers. In response to signals such as DNA damage, p53 controls the transcription of a series of genes that cause cell cycle arrest during which DNA damage is repaired, or triggers programmed cell death that eliminates possibly cancerous cells wherein DNA damage might have remain...
متن کاملTrex2 enables spontaneous sister chromatid exchanges without facilitating DNA double-strand break repair.
Trex2 is a 3' → 5' exonuclease that removes 3'-mismatched sequences in a biochemical assay; however, its biological function remains unclear. To address biology we previously generated trex2(null) mouse embryonic stem (ES) cells and expressed in these cells wild-type human TREX2 cDNA (Trex2(hTX2)) or cDNA with a single-amino-acid change in the catalytic domain (Trex2(H188A)) or in the DNA-bindi...
متن کاملDNA strand break repair and neurodegeneration.
A number of DNA repair disorders are known to cause neurological problems. These disorders can be broadly characterised into early developmental, mid-to-late developmental or progressive. The exact developmental processes that are affected can influence disease pathology, with symptoms ranging from early embryonic lethality to late-onset ataxia. The category these diseases belong to depends on ...
