      To study the relationships between different DNA repair pathways, we established a set of clones in which one specific DNA repair gene was silenced using long-term RNA interference in HeLa cell line. We focus here on genes involved in either nucleotide excision repair (XPA and XPC) or nonhomologous end joining (NHEJ; DNA-PKcs and XRCC4). As expected, XPAKD (knock down) Cited by: These findings indicate that Sir2, Sir3 and Sir4 also have a role in DNA double‐strand break repair through DNA end‐joining. In mammals, chromosomal inactivation and genomic imprinting are known to regulate gene expression through the formation of a heterochromatin structure on the X chromosome and other regions of the by:

DNA double strand breaks (DSBs) are particularly relevant to aging because of their toxicity, increased frequency with age and the association of defects in their repair with premature aging. Recent studies expand the potential impact of DNA damage and mutations on aging by linking DNA DSB repair and age-related chromatin by: DNA double-strand breaks (DSBs) occur in the context of a highly organized chromatin environment and are, thus, a significant threat to the epigenomic integrity of eukaryotic cells.

Changes in break-proximal chromatin structure are thought to be a prerequisite for efficient DNA repair and may help protect the structural integrity of the by: expression. In contrast, heterochromatin is a more tightly packed form of chromatin (Figure1) [2,3] where there is limited access to transcription factors and DNA repair proteins.

The aim here is to review the literature on the repair of DSBs in heterochromatin, focusing on repair in mammalian cells, unless otherwise by: Silencing, Heterochromatin and DNA Double Strand Break Repair by Kevin D. Mills. English | Oct 3, | ISBN: | Pages | PDF | 10 MB.

The field of DNA repair is vast and advancing rapidly. Silencing, Heterochromatin and DNA Double Strand Break Repair probes the relationship of DNA break repair and silent heterochromatin, using budding yeast as a model. The primary research presented in this book represents some of the most important work in this new field of inquiry.

DNA double-strand breaks (DSBs) are among the most damaging lesions in DNA, since, if not identified and repaired, they can lead to insertions, deletions or chromosomal rearrangements.

DSBs can be in the form of simple or complex breaks, and may be repaired by one of a number of processes, the nature of which depends on the complexity of the break or the position of the break within the by:   Read "Silencing, Heterochromatin and DNA Double Strand Break Repair" by Kevin D.
