• The well-known cancer susceptibility genes BRCA1 and BRCA2 are also examples of FA genes (FANCS and FANCD1 respectively), and biallelic mutation of any of the two genes usually results in an embryonically lethal outcome, and should the proband come to term, experience a severe form of Fanconi anemia.
• The BRCA1 gene is cloned by scientists at University of Utah, National Institute of Environmental Health Sciences (NIEHS) and Myriad Genetics.
• B3/B4 tRNA-binding domain - B5 protein domain - BAC - back mutation - bacteria - bacterial artificial chromosome - bacteriophage - bacteriophage lambda - bacteriophage scaffolding proteins - band shift assay - base - base pair - benzoyl-CoA 2,3-dioxygenase - benzyl benzoate/disulfiram - benzyl-2-methyl-hydroxybutyrate dehydrogenase - beta-carotene 3-hydroxylase - beta-cyclopiazonate dehydrogenase - beta-glucan-transporting ATPase - beta2-adaptin C-terminal domain - binding site - biological organisation - biological process - Biomolecular gradient - Biomolecule Stretching Database - biotin - birth defect - blotting - blunt end - bone marrow transplantation - box - BP - BRCA1 - BRCA2 - Brix (database) - BSD domain - BURP domain -.
• Homologous recombinational repair of DNA double-strand breaks mediated by BRCA1 and ATM weakens with age in oocytes of humans and other species.
• also showed that expression of four key DNA repair genes that are necessary for homologous recombinational repair (BRCA1, MRE11, Rad51 and ATM) decline in oocytes with age.
• Some of the uses of MRI of the breasts are: screening for malignancy in women with greater than 20% lifetime risk of breast cancer (especially those with high risk genes such as BRCA1 and BRCA2), evaluate breast implants for rupture, screening the opposite side breast for malignancy in women with known one sided breast malignancy, extent of disease and the presence of multifocality and multicentricity in patients with invasive carcinoma and ductal carcinoma in situ (DCIS), and evaluate response to neoadjuvant chemotherapy.
• Prophylactic salpingo-oophorectomy (removal of the ovaries and fallopian tubes to prevent cancer) is recommended at age 35-40 for people with BRCA1 mutations and at age 40-45 for people with BRCA2 mutations.
• Another example are the BRCA mutations; inheriting one defective BRCA allele results in a greatly increased risk of breast cancer and ovarian cancer, while inheriting both defective alleles will result in a severe form of Fanconi anemia (FA-S for BRCA1, FA-D1 for BRCA2) that is embryonically lethal in most cases.
• miR-17 and miR-30c-1, these patients were noncarriers of BRCA1 or BRCA2 mutations, lending the possibility that familial breast cancer may be caused by variation in these miRNAs.
• Young Hispanic women, premenopausal women, and women who test positive for the BRCA1 gene mutation, also have a higher prevalence of TNBC diagnosis.
• This protein is monoubiquitinated in response to DNA damage, resulting in its localization to nuclear foci with other proteins (BRCA1 and BRCA2) involved in homology-directed DNA repair (see Figure: Recombinational repair of DNA double-strand damages).
• DNA interstrand crosslinks are highly deleterious damages that are repaired by homologous recombination involving coordination of FA proteins and breast cancer susceptibility gene 1 (BRCA1), but the exact biochemical roles of these proteins is currently unclear.
• BRIP1 co-localizes with TOPBP1 scaffold protein and the BRCA1 repair protein along chromosome cores starting early in meiotic prophase I forming discrete foci, and is also densely localized to the axes of unsynapsed chromosomes during the late zygonema (zygotene) stage of meiosis.
• The FA core complex is a nuclear core complex that is essential for the monoubiquitination of FANCD2 and this modified form of FANCD2 colocalizes with BRCA1, RAD51 and PCNA in foci that also contain other DNA repair proteins.
• DNA interstrand crosslinks are highly deleterious damages that are repaired by homologous recombination involving coordination of FA proteins and breast cancer susceptibility gene 1 (BRCA1).
• BRCA1, BRCA2 and PALB2 are proteins that are important for the repair of double-strand DNA breaks by the error-free homologous recombinational repair, or HRR, pathway.
• In particular his laboratory discovered that loss of a nucleotide pool scavenger known as DNPH1 sensitises cancer cells to olaparib, a drug that is currently in use in the clinic for the treatment of breast, ovarian and prostate cancers caused by inheritable mutations in BRCA1 or BRCA2.
• Notable examples of potentially predictive cancer biomarkers include mutations on genes KRAS, p53, EGFR, erbB2 for colorectal, esophageal, liver, and pancreatic cancer; mutations of genes BRCA1 and BRCA2 for breast and ovarian cancer; abnormal methylation of tumor suppressor genes p16, CDKN2B, and p14ARF for brain cancer; hypermethylation of MYOD1, CDH1, and CDH13 for cervical cancer; and hypermethylation of p16, p14, and RB1, for oral cancer.
• Examples include ataxia telangiectasia – which is a mutation in the damage response kinase ATM – and BRCA1 or MRN complex mutations that play a role in responding to DNA damage.
