Homologous recombination (HR) is an important process that plays multiple crucial roles during meiosis, a type of cell cycle dedicated to sexual reproduction. During HR, homologous DNA molecules ...
Tokyo, Japan – Researchers from Tokyo Metropolitan University have been studying DNA repair by homologous recombination, where the RecA protein repairs breaks in double-stranded DNA by incorporating a ...
A recent study, undertaken by researchers at the Tokyo Metropolitan University and the Tokyo Metropolitan Institute of Medical Science (both Japan), unravels key steps in the process of homologous ...
New findings suggest an explanation for the century-old mystery of how chromosome recombination is regulated during sexual reproduction. In most higher organisms, including humans, every cell carries ...

A new role for DNA loops in repairing genetic damage
When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its ...
Genetic recombination (also known as genetic reshuffling) is the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ ...
Use of an RNA-based HRD signature significantly expands the fraction of patients with prostate cancer who may derive benefit from poly (ADP-ribose) polymerase inhibitors (PARPis) compared with using ...
Eight hundred and six patients were randomly assigned (2:1). Tumors were analyzed using the Myriad MyChoice HRD Plus assay to assess non–BRCA HRRm and HRD status; HRD was based on a genomic ...
