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.

Homologous Recombination Deficiency

open access: yesDefinitions, 2020
A DNA repair abnormality caused by mutations in one or more genes that are involved in homologous recombination repair. Deficient homologous recombination is associated with numerous neoplastic diseases and developmental disorders related to chromosomal ...

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 ...

Improved Gene Targeting through Cell Cycle Synchronization. [PDF]

open access: yesPLoS ONE, 2015
Gene targeting is a challenge in organisms where non-homologous end-joining is the predominant form of recombination. We show that cell division cycle synchronization can be applied to significantly increase the rate of homologous recombination during ...

The Landscape of Realized Homologous Recombination in Pathogenic Bacteria [PDF]

open access: yes, 2015
Recombination enhances the adaptive potential of organisms by allowing genetic variants to be tested on multiple genomic backgrounds. Its distribution in the genome can provide insight into the evolutionary forces that underlie traits, such as the ...

H4K20me0 recognition by BRCA1-BARD1 directs homologous recombination in sister chromatids

open access: yesNature Cell Biology, 2019
Genotoxic DNA double-strand breaks (DSBs) can be repaired by error-free homologous recombination (HR) or mutagenic non-homologous end-joining1. HR supresses tumorigenesis1, but is restricted to the S and G2 phases of the cell cycle when a sister ...

Arabidopsis RecQl4A suppresses homologous recombination and modulates DNA damage responses [PDF]

open access: yes, 2005
The DNA damage response and DNA recombination are two interrelated mechanisms involved in maintaining the integrity of the genome, but in plants they are poorly understood.

Mouse WRN Helicase Domain Is Not Required for Spontaneous Homologous Recombination-Mediated DNA Deletion

open access: yesJournal of Nucleic Acids, 2010
Werner syndrome is a rare disorder that manifests as premature aging and age-related diseases. WRN is the gene mutated in WS, and is one of five human RecQ helicase family members.

Prevalence of Homologous Recombination-Related Gene Mutations Across Multiple Cancer Types.

open access: yesJCO Precision Oncology, 2018
Purpose The prevalence of homologous recombination DNA damage repair (HR-DDR) deficiencies among all tumor lineages is not well characterized. Therapy directed toward homologous recombination DDR deficiency (HRD) is now approved in ovarian and breast ...

Using single loxP sites to enhance homologous recombination: ts mutants in Sec1 of Dictyostelium discoideum.

open access: yesPLoS ONE, 2007
BackgroundDictyostelium discoideum amoebae are haploid and, as they share many features with animal cells, should be an ideal creature for studying basic processes such as cell locomotion.
