Human Breast Cancer 2, Early Onset (BRCA2) interaction partners

1. Data found higher BRCA1/2 mRNA-expression in ovarian cancer (OC). BRCA1 mutated OCs exhibited lower BRCA1 but higher BRCA2 mRNA-expression. Low BRCA1-expression was associated with favorable overall survival and low BRCA2-expression with better progression-free and overall survival.

2. This is the largest study to date comparing outcomes in patients with EOC and BM by mutation status. mBRCA1 and mBCRA2 patients were more likely to have isolated BM, which may be a factor in their long survival.

3. RAD52 protein, just as BRCA2, interacts with pCHK1 checkpoint protein and helps maintain the checkpoint control in BRCA2 deficient cells during DNA damage response

4. BRCA 1/2 mutations are associated with a higher hematologic toxicity in patients with ovarian cancer who underwent platinum-based chemotherapy.

5. BRCA1/2 mutation testing thus has important and expanding roles in treatment planning for subsets of patients with breast cancer..Determining BRCA1/2 mutation status in this breast cancer subgroup could potentially expand treatment options beyond the current standard of taxane and anthracycline-based chemotherapy.

6. we believe we are the first to describe this germline mutation of BRCA2 (c.4211C>G, p.Ser1404Ter) in a patient with PCa, which was effectively treated with ADT and radiotherapy.

7. Protein truncating variants (PTVs) in specific DNA repair genes were significantly overrepresented among patients with the aggressive phenotype, with BRCA2, ATM and NBN the most frequently mutated genes.

8. Frequency of BRCA2 breast cancer pathogenic mutations in the Mexican population.

9. oursplicing analysis performed in three independent carriers show thatBRCA2c.7976+5G>T alleles produce a major in-frame transcript Delta17 predicted to encode a non-functional protein, and that even though variable proportions of additional transcripts (Delta16-18, Delta17,18,Delta18 and 17q224) have been detected, none of them arepredicted to rescue BRCA2 functionality.

10. Knowing a patient's BRCA mutation status is important for prevention and treatment decision-making. Improving the characterization of mutations will lead to better management, treatment, and BCa prevention efforts in African Americans who are disproportionately affected with aggressive BCa and may inform future precision medicine genomic-based clinical studies.

11. Among ovarian cancer patients, BRCA2 carriers with mutations located in the RAD51-BD (exon 11) have prolonged PFS, PFI, and OS.

12. The BRCA2 is the most prevalent type mutation among hereditary breast and/or ovarian cancer patients in the Arab region, with an estimated prevalence was 17% with a higher pooled prevalence of BRCA mutations in the Levant Region 28%. When compared with studies from different parts of the world the Arab world appear to have different profiles with varying BRCA frequencies.[meta-analysis]

13. Among Korean women with the BRCA1/2 mutation, the location of the mutations may influence the risk of breast and ovarian cancers according to the putative functional domain regions

14. Carriers of BRCA1/BRCA2 mutation with sporadic Pancreatic Ductal Adenocarcinoma had a worse survival after pancreatectomy than their BRCA wild-type counterparts. However, platinum-based chemotherapy regimens were associated with markedly improved survival in patients with BRCA1/BRCA2 mutations, with survival differences no longer appreciated with wild-type patients.

15. Assessment of the clinical relevance of BRCA2 missense variants by functional and computational approaches has been presented.

16. Identified APEX2 and FEN1 as synthetic lethal genes with both BRCA1 and BRCA2 loss of function in tumor cell lines.

17. BRCA2 expression is highly sensitive to promoter variations as most of them induced relevant changes. Moreover, we mapped critical regions of the BRCA2 promoter that may constitute potential targets for regulatory variants.

18. 14 had pathogenic variants in the BRCA1 gene and 5 had pathogenic variants in the BRCA2 gene

19. Different mechanisms inactivating the wild type allele are present within the same tumor sample at various extents. Results indicate that BRCA1/2-linked breast and ovarian cancer cells are predominantly characterized by LOH, but harbor a complex combination of second hits at various frequencies.

20. BRCA carriers with and without malignancy exhibit comparable ovarian reserve and responses to ovarian stimulation compared with women with BRCA-negative cancers and cancer-free controls.

Fruit Fly (Drosophila melanogaster) Breast Cancer 2, Early Onset (BRCA2) interaction partners

1. 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.

2. A mutation in Cyp6d2, a cytochrome P450 gene, when combined with a brca2 mutation, resulted in synergistic hypersensitivity to camptothecin.

3. DNA repair by homologous recombination is dramatically decreased in CG30169 (brca2 homolog) mutants.

Zebrafish Breast Cancer 2, Early Onset (BRCA2) interaction partners

1. the data suggest for the first time that brca2/fancd1 is essential for vertebrate kidney ontogeny.

2. Carcinogenesis in zebrafish with combined mutations in tp53 and brca2 typically requires biallelic mutation or loss of at least one of these genes.

3. The novel role of Brca2 in organizing the vertebrate egg nucleus may provide new insights into the origin of ovarian cancer

4. critical roles for brca2 in ovarian development and tumorigenesis in reproductive tissues

Mouse (Murine) Breast Cancer 2, Early Onset (BRCA2) interaction partners

1. BRCA2-proficient and deficient cells are radiosensitised by HT, indicating that HT does not exclusively act by inhibition of HR.

2. Results suggest that the greater reliance on homology-directed repair (HDR) in the proliferating mammary gland, rather than a specific dependence on breast cancer 2 protein (BRCA2), may increase its susceptibility to tumorigenesis incurred by BRCA2 mutation.

3. The functional consequence of Parp1 heterozygosity on BRCA2 loss is demonstrated by a significant increase in tumorigenesis in Brca2 knockout mice.

4. Data indicate the importance of breast cancer 1 protein (BRCA1)/breast cancer 2 protein (BRCA2) function in cranial neural crest cells (CNCCs) during craniofacial skeletal formation.

5. 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.

6. we describe a genetic approach to examine the functional significance of the interaction between BRCA2 and PALB2 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 and Trp53 heterozygosity .

15. Results suggest that cellular levels of Brca2 and Rad51 are mutually dependent on each other, and that low levels of these proteins provide selective pressure for reduction of p53, which permits cell growth

16. BRCA2 accumulates DNA damage, which triggers checkpoint signalling and ARF activation

17. data showed that silencing of BRCA2 promoted cell proliferation, migration and invasion in vitro; data reported here demonstrate that BRCA2 may be a promising therapeutic targets for pancreatic ductal adenocarcinoma progression

18. BRCA2 is required for telomere homeostasis and may be particularly important for the replication of G-rich telomeric lagging strands.

19. Loss of Brca2 function predisposes the exocrine pancreas to profound DNA damage, and the frequency of invasive neoplasia is accentuated by the concomitant deregulation of p53
