The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Competition between replicative and translesion polymerases during homologous recombination repair in Drosophila. [PDF]
PLoS Genetics, 2012 In metazoans, the mechanism by which DNA is synthesized during homologous recombination repair of double-strand breaks is poorly understood. Specifically, the identities of the polymerase(s) that carry out repair synthesis and how they are recruited to ...

DNA DSB repair pathway choice: an orchestrated handover mechanism [PDF]
, 2014 DNA double strand breaks (DSBs) are potential lethal lesions but can also lead to chromosome rearrangements, a step promoting carcinogenesis. DNA non-homologous end-joining (NHEJ) is the major DSB rejoining process and occurs in all cell cycle stages ...

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Replication dynamics of recombination-dependent replication forks
Nature Communications, 2021 Replication forks that are stalled at obstacles on the DNA template can be restarted by homologous recombination. Here, the authors show replication dynamics during homologous recombination-dependent replication fork restart by combining polymerase usage

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1
Molecular Oncology, EarlyView.Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

RAPID SOUTHERN BLOT PROTOCOL FOR THE ANALYSIS OF TARGETED MUTAGENESIS IN THE MOUSE IGHG1 LOCUS
Scientific Papers Animal Science and Biotechnologies, 2023 The efficiency of homologous recombination relies on the lenght of the homology arms and the chromatin compactation of the locus. In ES cells the immuoglobulin locu is compacted. Thus, the homologous recombination events occur at a very low frequency.

Altering symplectic manifolds by homologous recombination [PDF]
, 2010 We use symplectic cohomology to study the non-uniqueness of symplectic structures on the smooth manifolds underlying affine varieties. Starting with a Lefschetz fibration on such a variety and a finite set of primes, the main new tool is a method, which ...

Genetic Requirements for Intra-Chromosomal Deletions [PDF]
, 2020 Chromosomal deletions are one of the most dangerous types of DNA damage and often arise as a result of inappropriately repaired DNA double strand breaks (DSB).
