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. PMID:27779185

PMID:26920070
5. 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 . PMID:27490902

14. 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 PMID:24210700
15. BRCA2 accumulates DNA damage, which triggers checkpoint signalling and ARF activation PMID:24162189
16. 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 PMID:22934697
17. BRCA2 is required for telomere homeostasis and may be particularly important for the replication of G-rich telomeric lagging strands. PMID:22187435
18. 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 PMID:21455033
19. FANCD1/BRCA2 played notably important roles in the repair of TMZ-induced DNA damage. PMID:21573016
20. Data suggest that the growth-suppressive effect of CHK1 inhibition in BRCA2-mutant tumors can be opposed by concurrent KRAS activation and TP53 mutations. PMID:21289082
21. Trp53 signaling must be modified before inactivation of the Brca2 wild-type allele, irrespective of Kras status, for Brca2-deficient cells to form pancreatic tumors PMID:21199651
22. BRCA2 associates with telomeres during the S and G2 phases of the cell cycle and facilitates the loading of RAD51 onto telomeres. PMID:21076401
23. Germline heterozygosity for a pathogenic Brca2 truncation suffices to promote pancreatic ductal adenocarcinomas driven by Kras(G12D), irrespective of Trp53 status. PMID:21056012
24. Simultaneous deletion of Brca2 and the tumour suppressor Trp53 in prostate epithelia gave rise to focal hyperplasia and atypical cells PMID:20585617
25. Loss of Brca2 increases in vivo somatic mutation acquisition and synergizes with ionizing radiation exposure. PMID:11850397
26. Genomic organization and expression of the mouse Brca2 gene PMID:12140683

28. The extreme carboxy-terminal region encoded by exon 27 is vital for BRCA2 function in mice, perhaps because it is required for a fully functional interaction between BRCA2 and RAD51, though it is less severe than truncations that delete some BRC motifs. PMID:12619154
