Imprecision and DNA Break Repair Biased towards Incompatible End Joining in Leukemia [PDF]
Abstract Cancer is a genetic disease caused by mutations and chromosomal abnormalities that contribute to uncontrolled cell growth. In addition, cancer cells can rapidly respond to conventional and targeted therapies by accumulating novel and often specific genetic lesions leading to acquired drug resistance and relapsing disease.

Assays for DNA double-strand break repair by microhomology-based end-joining repair mechanisms [PDF]
DNA double stranded breaks (DSBs) are one of the most deleterious types of DNA lesions. The main pathways responsible for repairing these breaks in eukaryotic cells are homologous recombination (HR) and non-homologous end-joining (NHEJ). However, a third group of still poorly characterized DSB repair pathways, collectively termed microhomology-mediated

Preventing Nonhomologous End Joining Suppresses DNA Repair Defects of Fanconi Anemia [PDF]
Fanconi anemia (FA) is a complex cancer susceptibility disorder associated with DNA repair defects and infertility, yet the precise function of the FA proteins in genome maintenance remains unclear. Here we report that C. elegans FANCD2 (fcd-2) is dispensable for normal meiotic recombination but is required in crossover defective mutants to prevent ...

DNA break site at fragile subtelomeres determines probability and mechanism of antigenic variation in African trypanosomes. [PDF]
Antigenic variation in African trypanosomes requires monoallelic transcription and switching of variant surface glycoprotein (VSG) genes. The transcribed VSG, always flanked by '70 bp'-repeats and telomeric-repeats, is either replaced through DNA double ...

A Sir2-like protein participates in mycobacterial NHEJ. [PDF]
In eukaryotic cells, repair of DNA double-strand breaks (DSBs) by the nonhomologous end-joining (NHEJ) pathway is critical for genome stability. In contrast to the complex eukaryotic repair system, bacterial NHEJ apparatus consists of only two proteins ...

DNA double-strand breaks are lesions that form during metabolism, DNA replication and exposure to mutagens. When a double-strand break occurs one of a number of repair mechanisms is recruited, all of which have differing propensities for mutational ...

Xlf1 Is Required for DNA Repair by Nonhomologous End Joining in Schizosaccharomyces pombe [PDF]
Abstract The accurate repair of DNA double-strand breaks is essential for cell survival and maintenance of genome integrity. Here we describe xlf1+, a gene in the fission yeast Schizosaccharomyces pombe that is required for repair of double-strand breaks by nonhomologous end joining during G1 phase of the cell cycle. Xlf1 is the ortholog

Specific Roles of XRCC4 Paralogs PAXX and XLF during V(D)J Recombination
Paralog of XRCC4 and XLF (PAXX) is a member of the XRCC4 superfamily and plays a role in nonhomologous end-joining (NHEJ), a DNA repair pathway critical for lymphocyte antigen receptor gene assembly.

Repair of DNA double-strand breaks by mammalian alternative end-joining pathways [PDF]
Alternative end-joining (a-EJ) pathways, which repair DNA double-strand breaks (DSBs), are initiated by end resection that generates 3' single strands. This reaction is shared, at least in part, with homologous recombination but distinguishes a-EJ from the major nonhomologous end-joining pathway.
