Shieldin complex promotes DNA end-joining and counters homologous recombination in BRCA1-null cells

open access: yesNature Cell Biology, 2018
BRCA1 deficiencies cause breast, ovarian, prostate and other cancers, and render tumours hypersensitive to poly(ADP-ribose) polymerase (PARP) inhibitors.

Mutations in pathways depending on BRCA1 and BRCA2 may increase cancer risks from an environmental carcinogen [PDF]

open access: yes, 2011
Recently, the President’s Cancer Panel [2008-2009] protested that preventive action is not taken when uncertainty exists about potential harm from a chemical, because the US regulatory approach demands that a hazard be incontrovertibly ...

Competition between replicative and translesion polymerases during homologous recombination repair in Drosophila. [PDF]

open access: yesPLoS 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 ...

Homolog pairing during meiosis : dyneins on the move [PDF]

open access: yes, 2010
Meiosis is a specialized form of cell division that generates haploid gametes from diploid cells. This is achieved by having 1 round of DNA replication followed by 2 rounds of nuclear division.

The anaphase promoting complex impacts repair choice by protecting ubiquitin signalling at DNA damage sites

open access: yesNature Communications, 2017
The choice between homologous recombination and non-homologous end-joining is largely influenced by cell cycle. Here the authors show that APCCdh1 promotes homologous recombination by removing USP1, allowing polyubiquitinated histones to recruit BRCA1.

Measuring Homologous Recombination Rates between Chromosomal Locations in Salmonella

open access: yesBio-Protocol, 2019
Homologous recombination between two similar DNA molecules, plays an important role in the repair of double-stranded DNA breaks. Recombination can occur between two sister chromosomes, or between two locations of similar sequence identity within the same

Targeted recombination of homologous chromosomes using CRISPR‐Cas9

open access: yesFEBS Open Bio, 2023
CRISPR mutagenesis is an efficient way to disrupt specific target genes in many model organisms. We previously devised a targeted CRISPR recombination method to generate intragenic recombinants of alleles in Drosophila.

Mutational Effects of Mobile Introns on the Mitochondrial Genomes of Metschnikowia Yeasts

open access: yesFrontiers in Genetics, 2021
It has been argued that DNA repair by homologous recombination in the context of endonuclease-mediated cleavage can cause mutations. To better understand this phenomenon, we examined homologous recombination following endonuclease cleavage in a native ...

PARP Inhibitors as a Therapeutic Agent for Homologous Recombination Deficiency in Breast Cancers

open access: yesJournal of Clinical Medicine, 2019
Poly (ADP-ribose) polymerases (PARPs) play an important role in various cellular processes, such as replication, recombination, chromatin remodeling, and DNA repair.

Plant DNA Recombinases: A Long Way to Go

open access: yesJournal of Nucleic Acids, 2010
DNA homologous recombination is fundamental process by which two homologous DNA molecules exchange the genetic information for the generation of genetic diversity and maintain the genomic integrity.
