observations indicate that nascent DNA degradation in BRCA1/2-deficient cells occurs as a consequence of MRE11 (show MRE11A ELISA Kits)-dependent nucleolytic processing of reversed forks generated by fork remodelers
Evidence does not support routine risk-reducing hysterectomy for BRCA1 and BRCA2 mutation carriers.
WTIP (show WTIP ELISA Kits) interacts with BRCA2 and might be responsible for BRCA2 centrosome localization in cervical cancer cell.
Founder mutations in BRCA2 contribute to an increased risk of ovarian and breast cancer in the western Danish population.
BRCA2 germline mutation is associated with triple-negative breast cancer.
BRCA2 c.68-7T>A pathogenic mutation from Norwegian breast or ovarian cancer cohort
These results reveal a synthetic lethal relationship between FANCD2 and BRCA1/2.
This study implicates novel risk loci as well as highlights the clinical utility for retesting BRCA1/2 negative ovarian cancer patients by genomic sequencing and analysis of genes in relevant pathways.
Women with BRCA1/2 mutations show at diagnosis higher peritoneal tumor load and increased frequency of bulky lymph nodes compared to patients without germline BRCA mutations. Primary debulking surgery seems to ensure a longer progression-free survival in women with BRCA wild type genotype compared to neoadjuvant chemotherapy.
Sixteen VUS from 51 BRCA1 variants of uncertain significance (VUS) carriers and 28 VUS from 62 BRCA2 VUS carriers were analyzed. There was a slight agreement between the two analyses, with a kappa value of 0.14 (95% confidence interval (CI) = -0.34 to 0.62) for the BRCA1 VUS and a kappa value of 0.17 (95% CI = -0.10 to 0.49) for the BRCA2 VUS
persistent meiotic DNA double-strand breaks might correspond to crossovers, which are mobilized to the nuclear envelope for their repair; Brca2-Pds5 complexes may be key mediators of this process.
A mutation in Cyp6d2, a cytochrome P450 gene, when combined with a brca2 mutation, resulted in synergistic hypersensitivity to camptothecin.
DNA repair by homologous recombination is dramatically decreased in CG30169 (brca2 homolog) mutants.
the data suggest for the first time that brca2/fancd1 is essential for vertebrate kidney ontogeny.
Carcinogenesis in zebrafish with combined mutations in tp53 (show TP53 ELISA Kits) and brca2 typically requires biallelic mutation or loss of at least one of these genes.
The novel role of Brca2 in organizing the vertebrate egg nucleus may provide new insights into the origin of ovarian cancer
critical roles for brca2 in ovarian development and tumorigenesis in reproductive tissues
we generated a Brca2 knock-in mouse model lacking exons 4-7 and demonstrated that these exons are dispensable for viability as well as tumor-free survival. This study provides the first in vivo evidence of the functional significance of a minor transcript of BRCA2 that can play a major role in the survival of humans who are homozygous for a clearly pathogenic mutation.
we describe a genetic approach to examine the functional significance of the interaction between BRCA2 and PALB2 (show PALB2 ELISA Kits) by generating a knock-in mouse model of Brca2 carrying a single amino acid change (Gly25Arg, Brca2G25R) that disrupts this interaction. In addition, we have combined Brca2G25R homozygosity as well as hemizygosity with Palb2 (show PALB2 ELISA Kits) and Trp53 (show TP53 ELISA Kits) heterozygosity .
Merit40 (show BABAM1 ELISA Kits) mutation exacerbated ICL-induced chromosome instability in the context of concomitant Brca2 deficiency but not in conjunction with Fancd2 (show FANCD2 ELISA Kits) mutation.
Heterozygous and homozygous Brca2 mutation may lead to dysfunction in T cell populations.
BRCA2 exon 27 domain maintains chromosomal integrity at both stalled and collapsed replication forks consistent with involvement in both replication fork maintenance and double strand break repair.
we use a genetically engineered mouse model of BRCA2-associated hereditary breast cancer to study drug resistance to several types of chemotherapy and PARP (show PARP1 ELISA Kits) inhibition.
BRCA2-mediated sequestration of nuclear RAD51 (show RAD51 ELISA Kits) serves to prevent inappropriate DNA interactions.
BRCA2 directly represses the expression of IFN-related genes
the models reveal novel aspects of cancer evolution in carriers of germline BRCA2 mutations, provide new insights into the tumour suppressive role of BRCA2
genetic stability, and hematopoietic differentiation potential of gene-corrected Brca2(Delta) (27/) (Delta) (27) iPSCs, achievements and limitations in the application of current reprogramming approaches in hematopoietic stem cell therapy are also discussed.
Inherited mutations in BRCA1 and this gene, BRCA2, confer increased lifetime risk of developing breast or ovarian cancer. Both BRCA1 and BRCA2 are involved in maintenance of genome stability, specifically the homologous recombination pathway for double-strand DNA repair. The BRCA2 protein contains several copies of a 70 aa motif called the BRC motif, and these motifs mediate binding to the RAD51 recombinase which functions in DNA repair. BRCA2 is considered a tumor suppressor gene, as tumors with BRCA2 mutations generally exhibit loss of heterozygosity (LOH) of the wild-type allele.
