1. Recognition and signaling of DNA double-strand breaks in human cells
Sammanfattning : DNA double-strand breaks (DSBs) are the most toxic type of DNA damage. Fortunately, our cells have highly conserved pathways that detect and repair DSBs. Defects in DSB signaling and DSB repair pathways result in genomic instability that predisposes for cancer development. LÄS MER
2. DNA double-strand break repair in ascomycetes
Sammanfattning : Nonhomologous end joining (NHEJ) and homologous recombination (HR) are two pathways for DNA double strand break (DSB) repair. We found that the NHEJ protein Nej1 interacted physically with the HR protein Srs2, which was dependent on phosphorylation of Nej1 by Dun1. Srs2 recruitment to a DSB partly relied on Nej1 and Dun1.

3. Characterization of Budding Yeast Nonhomologous End-Joining at DNA Double-Strand Breaks and Telomeres
Sammanfattning : The yeast K. lactis efficiently integrates DNA by illegitimate recombination (IR). IR was completely dependent upon nonhomologous end-joining (NHEJ). In contrast to S. LÄS MER
4. Repair of DNA double-stranded breaks in human cells
Sammanfattning : DNA is continuously subjected to degradation. Therefore, our cells need to constantly repair its DNA to prevent mutations and in the long run cancer. In mammalian cells, when DNA is broken right off, a double-stranded break (DSB) is produced, and the ends are ligated by a process called non-homologous end-joining (NHEJ). LÄS MER
5. Measurements of the DNA double-strand break response
Sammanfattning : Radiotherapy and some chemotherapeutic drugs kill cancer cells by induction of the extremely toxic DNA double-strand breaks (DSBs). Measurements of the DSB response in patients during therapy could allow personalized dosing to improve tumor response and minimize side effects. LÄS MER
