1596 Background: Magnetic resonance imaging (MRI) is the preferred imaging modality for screening and diagnosis of breast cancer in BRCA-1and BRCA-2 mutation carriers. However, there is limited data on the radiographic features of BRCA1/2-positive breast cancers on MRI. This study evaluates the MRI characteristics of BRCA1/2 -related breast cancers. METHODS All female BRCA mutation carriers w...

Our objectives were to test whether polymorphic variation in the (CAG)n repeat of the androgen receptor (AR) gene affects penetrance of germ-line BRCA mutations for ovarian cancer or age of diagnosis for ovarian cancer. Using a case-series study design, 179 consecutive Ashkenazi Jewish ovarian cancer patients were genotyped for AR repeat length and BRCA mutation status. There was no association...

Ovarian cancer is a heterogeneous disease that encompasses a number of different cellular subtypes, the most common of which is high-grade serous ovarian cancer (HGSOC). Still today, ovarian cancer is primarily treated with chemotherapy and surgery. Recent advances in the hereditary understanding of this disease have shown a significant role for the BRCA gene. While only a minority of patients ...

UNLABELLED PARP inhibitors exploit synthetic lethality to target epithelial ovarian cancer (EOC) with hereditary BRCA mutations and defects in homologous recombination repair (HRR). However, such an approach is limited to a small subset of EOC patients and compromised by restored HRR due to secondary mutations in BRCA genes. Here, it was demonstrated that triapine, a small-molecule inhibitor of...

Fanconi anemia (FA) is a heterogeneous recessive disorder associated with a markedly elevated risk to develop cancer. To date sixteen FA genes have been identified, three of which predispose heterozygous mutation carriers to breast cancer. The FA proteins work together in a genome maintenance pathway, the so-called FA/BRCA pathway which is important during the S phase of the cell cycle. Since n...

Breast cancer 1 antigen (BRCA 1) and breast cancer 2 antigen (BRCA2) genes play a significant role in deoxyribonucleic acid (DNA) repair by means of interstrand crosslink repair, and deleterious germline mutations of these are responsible for most hereditary breast and ovarian cancers. Therapeutic strategies which specifically target interstrand crosslink repair can therefore be helpful in pati...

Inheritance of one defective copy of either of the two breast-cancer-susceptibility genes, BRCA1 and BRCA2, predisposes individuals to breast, ovarian and other cancers. Both genes encode very large protein products; these bear little resemblance to one another or to other known proteins, and their precise biological functions remain uncertain. Recent studies reveal that the BRCA proteins are r...

BACKGROUND Early serous carcinomas predominate in the fimbria of women with BRCA mutations (BRCA+). An entity in non-neoplastic mucosa sharing several properties of early serous carcinomas--the "p53 signature"--has been described in the distal fallopian tube and proposed as a precursor to serous carcinomas. This study compared the prevalence of p53 signatures in ovarian cortical inclusion cysts...

Currently, metastatic breast cancer (BrCa) provides a crucial clinical challenge. Metastasis occurs as part of a cascade of BrCa evolution, after vascular remodeling and extravasation at the tumor site occur. BrCa tumors commonly metastasize into bone; therefore, it is important to develop a working bone model that accurately simulates the metastasis, arrival, and eventual invasion of BrCa into...
