Both homologous and nonhomologous recombination events occur at high efficiency in DNA molecules transfected into mammalian cells. Both types of recombination occur with similar overall efficiencies, as measured by an endpoint assay, but their relative rates are unknown. In this communication, we measure the relative rates of homologous and nonhomologous recombination in DNA transfected into mo...

Purpose: Hallmarks of germline BRCA1/2-associated ovarian carcinomas include chemosensitivity and improved survival. The therapeutic impact of somatic BRCA1/2 mutations and mutations in other homologous recombination DNA repair genes is uncertain. Experimental Design: Using targeted capture and massively parallel genomic sequencing, we assessed 390ovarian carcinomas for germline and somatic los...

We regret the incorrect designation of site attacking 3′-phosphotyrosine as 3′-hydroxyl group in process following formation Holliday junction intermediate to complete Cre/ loxP mediated recombination homologous DNA fragments.

آسیب های وارده به dna می تواند نواقصی را در رونوشت rna و پروتئین های ترجمه شده ی آنها بر جای گذارد که باید ترمیم گردد. یکی از این آسیب ها شکست های دو رشته ای dna است که سیستم ترمیمی این نوع شکست، شامل دو مسیرnonhomologous end joining (nhej) و homologous recombination (hr) می باشد. هر گونه تغییرات مثل چند شکلی های ژنتیکی در این دو مسیر ترمیمی می تواند منجر به سرطان شود. پروتئین های درگیر در مسیر...

BRCA2 has been implicated in the maintenance of genome stability and RAD51-mediated homologous recombination repair of chromosomal double-strand breaks (DSBs), but its role in these processes is unclear. To gain more insight into its role in homologous recombination, we expressed wild-type BRCA2 in the well-characterized BRCA2-deficient human cell line CAPAN-1 containing, as homologous recombin...

The following review presents a problem of metastatic castration-resistant prostate cancer and its association with germline or somatic mutations in homologous recombination repair (HRR). In 2020, olaparib was approved the Russian Federation as monotherapy for genes involved DNA by recombination, after progression on therapy new hormonal drugs. We describe main clinical trials assessing efficac...

Although DNA sequence homology is believed to be a prerequisite for homologous recombination events in procaryotes and eucaryotes, no systematic study has been done on the minimum amount of homology required for homologous recombination in mammalian cells. We have used simian virus 40-pBR322 hybrid plasmids constructed in vitro as substrates to quantitate intramolecular homologous recombination...

Brome mosaic virus (BMV), a tripartite positive-stranded RNA virus of plants engineered to support intersegment RNA recombination, was used for the determination of sequence and structural requirements of homologous crossovers. A 60-nucleotide (nt) sequence, common between wild-type RNA2 and mutant RNA3, supported efficient repair (90%) of a modified 3' noncoding region in the RNA3 segment by h...
