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.

Variation in RAD51 details a hub of functions: opportunities to advance cancer diagnosis and therapy [version 2; referees: 4 approved]

open access: yesF1000Research, 2018
Loss of genome stability is one of the hallmarks of the enabling characteristics of cancer development. Homologous recombination is a DNA repair process that often breaks down as a prelude to developing cancer. Conversely, homologous recombination can be

PCR artifact in testing for homologous recombination in genomic editing in zebrafish. [PDF]

open access: yesPLoS ONE, 2017
We report a PCR-induced artifact in testing for homologous recombination in zebrafish. We attempted to replace the lnx2a gene with a donor cassette, mediated by a TALEN induced double stranded cut.

Guidelines for identifying homologous recombination events in influenza A virus. [PDF]

open access: yesPLoS ONE, 2010
The rapid evolution of influenza viruses occurs both clonally and non-clonally through a variety of genetic mechanisms and selection pressures. The non-clonal evolution of influenza viruses comprises relatively frequent reassortment among gene segments ...

Enhanced radiosensitivity of head and neck cancer cells to proton therapy via hyperthermia-induced homologous recombination deficiency

open access: yesClinical and Translational Radiation Oncology
Background and purpose: Radiotherapy induces tumor cell killing by generating DNA double strand breaks (DSBs). The effectiveness of radiotherapy is significantly influenced by the repair of DSBs, which counteracts this lethal effect.

Drosophila brca2 is required for mitotic and meiotic DNA repair and efficient activation of the meiotic recombination checkpoint.

open access: yesPLoS Genetics, 2008
Heterozygous mutations in the tumor suppressor BRCA2 confer a high risk of breast and other cancers in humans. BRCA2 maintains genome stability in part through the regulation of Rad51-dependent homologous recombination. Much about its precise function in

HO Endonuclease-Initiated Recombination in Yeast Meiosis Fails To Promote Homologous Centromere Pairing and Is Not Constrained To Utilize the Dmc1 Recombinase

open access: yesG3: Genes, Genomes, Genetics, 2018
Crossover recombination during meiosis is accompanied by a dramatic chromosome reorganization. In Saccharomyces cerevisiae, the onset of meiotic recombination by the Spo11 transesterase leads to stable pairwise associations between previously ...

Pan-cancer landscape of homologous recombination deficiency

open access: yesNature Communications, 2020
Cancers deficient in homologous recombination can benefit from treatment with poly ADP-ribose polymerase (PARP) inhibitors. Here, the authors generated a classifier that can predict homologous recombination deficiency from genomic data and suggest ...

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

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 ...
