Influence of the MDM2 single nucleotide polymorphism SNP309 on tumour development in BRCA1 mutation carriers [PDF]

, 2006
BackgroundThe MDM2 gene encodes a negative regulator of the p53 tumour suppressor protein. A single nucleotide polymorphism (SNP) in the MDM2 promoter (a T to G exchange at nucleotide 309) has been reported to produce accelerated tumour formation in ...

Characterization of a carboxy-terminal BRCA1 interacting protein [PDF]

Oncogene, 1998
There are several lines of evidence indicating that the carboxy-terminal region of the tumor suppressor protein BRCA1 is a functionally significant domain. Using the yeast two-hybrid and in vitro biochemical assays, we show that a protein, CtIP, interacts specifically with the carboxy-terminal segment of human BRCA1 from residues 1602-1863. A germ line

Targeting BRCA1-BER deficient breast cancer by ATM or DNA-PKcs blockade either alone or in combination with cisplatin for personalized therapy [PDF]

, 2014
BRCA1, a key factor in homologous recombination repair may also regulate base excision repair (BER). Targeting BRCA1-BER deficient cells by blockade of ATM and DNA-PKcs could be a promising strategy in breast cancer.

NF-κB regulates DNA double-strand break repair in conjunction with BRCA1-CtIP complexes [PDF]

, 2011
NF-κB is involved in immune responses, inflammation, oncogenesis, cell proliferation and apoptosis. Even though NF-κB can be activated by DNA damage via Ataxia telangiectasia-mutated (ATM) signalling, little was known about an involvement in DNA repair ...

Functional analyses of rare germline BRCA1 variants by transcriptional activation and homologous recombination repair assays

BMC Cancer, 2023
Background Damaging alterations in the BRCA1 gene have been extensively described as one of the main causes of hereditary breast and ovarian cancer (HBOC).

Methylation and protein expression of DNA repair genes: association with chemotherapy exposure and survival in sporadic ovarian and peritoneal carcinomas

Molecular Cancer, 2009
Background DNA repair genes critically regulate the cellular response to chemotherapy and epigenetic regulation of these genes may be influenced by chemotherapy exposure.

BRCA1 and TOP2A gene amplification and protein expression in four molecular subtypes of breast cancer [PDF]

Archives of Biological Sciences, 2013
We studied TOP2A amplification (using FISH methods), and TOP2A and BRCA1 protein overexpression (immunohistochemistry) in four molecular subtypes of breast cancer. Of 53 patients, 32 showed TOP2A and 38 showed BRCA1 overexpression.

A comprehensive model for familial breast cancer incorporating BRCA1, BRCA2 and other genes. [PDF]

, 2002
In computing the probability that a woman is a BRCA1 or BRCA2 carrier for genetic counselling purposes, it is important to allow for the fact that other breast cancer susceptibility genes may exist.

Structure-Function Of The Tumor Suppressor BRCA1

Computational and Structural Biotechnology Journal, 2012
BRCA1, a multi-domain protein, is mutated in a large percentage of hereditary breast and ovarian cancers. BRCA1 is most often mutated in three domains or regions: the N-terminal RING domain, exons 11-13, and the BRCT domain.
