How cancer cells hijack DNA double-strand break repair pathways to gain genomic instability.
DNA DSBs (double-strand breaks) are a significant threat to the viability of a normal cell, since they can result in loss of genetic material if mitosis or replication is attempted in their presence. Consequently, evolutionary pressure has resulted in multiple pathways and responses to enable DSBs to be repaired efficiently and faithfully. Cancer cells, which are under pressure to gain genomic ...
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-adox: Restoration of suppressed double-strand break repair during mitosis induces genomic instability
Double-strand breaks (DSBs) are one of the severest types of DNA damage. Unrepaired DSBs easily induce cell death and chromosome aberrations. To maintain genomic stability, cells have checkpoint and DSB repair systems to respond to DNA damage throughout most of the cell cycle. The failure of this process often results in apoptosis or genomic instability, such as aneuploidy, deletion, or translo...
متن کاملSMC1 coordinates DNA double-strand break repair pathways.
The SMC1/SMC3 heterodimer acts in sister chromatid cohesion, and recent data indicate a function in DNA double-strand break repair (DSBR). Since this role of SMC proteins has remained largely elusive, we explored interactions between SMC1 and the homologous recombination (HR) or non-homologous end-joining (NHEJ) pathways for DSBR in Saccharomyces cerevisiae. Analysis of conditional single- and ...
