Abnormal expression of BRCA1 and BRCA1‐interactive DNA‐repair proteins in breast carcinomas [PDF]

International Journal of Cancer, 2000
Breast cancer is one of the most common malignancies among women. The molecular mechanisms involved in breast carcinogenesis, however, remain to be elucidated. Although somatic mutation of BRCA1 is rare, BRCA1 protein expression is reduced in about 30% of sporadic breast carcinomas (Yoshikawa et al., Clin.

CRL4-DCAF8L1 Regulates BRCA1 and BARD1 Protein Stability [PDF]

International Journal of Biological Sciences, 2022
BRCA1 is frequently down-regulated in breast cancer, the underlying mechanism is unclear. Here we identified DCAF8L1, an X-linked gene product, as a DDB1-Cullin associated Factor (DCAF) for CUL4 E3 ligases to target BRCA1 and BARD1 for proteasomal degradation.

BRCA1‐associated protein (BAP1)‐inactivated melanocytic tumors [PDF]

Journal of Cutaneous Pathology, 2019
AbstractAlthough discussed using variable terminology, cutaneous BRCA1‐associated protein (BAP1)‐inactivated melanocytic tumor (BIMT) has been considered a discrete diagnostic entity since 2011. Here, we review the initial genomic studies that identified these distinct melanocytic tumors and the clinical and histopathological features that define these

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.

BRCA1 interacts with Smad3 and regulates Smad3-mediated TGF-beta signaling during oxidative stress responses. [PDF]

PLoS ONE, 2009
BRCA1 is a key regulatory protein participating in cell cycle checkpoint and DNA damage repair networks. BRCA1 plays important roles in protecting numerous cellular processes in response to cell damaging signals. Transforming growth factor-beta (TGF-beta)

Functional Restoration of BRCA1 Nonsense Mutations by Aminoglycoside-Induced Readthrough

Frontiers in Pharmacology, 2022
BRCA1 is a major tumor suppressor that functions in the accurate repair of DNA double-strand breaks via homologous recombination (HR). Nonsense mutations in BRCA1 lead to inactive truncated protein products and are associated with high risk of breast and

Attenuation of RNA polymerase II pausing mitigates BRCA1-associated R-loop accumulation and tumorigenesis. [PDF]

, 2017
Most BRCA1-associated breast tumours are basal-like yet originate from luminal progenitors. BRCA1 is best known for its functions in double-strand break repair and resolution of DNA replication stress.

PHF2 regulates homology-directed DNA repair by controlling the resection of DNA double strand breaks [PDF]

, 2020
Post-translational histone modifications and chromatin remodelling play a critical role controlling the integrity of the genome. Here, we identify histone lysine demethylase PHF2 as a novel regulator of the DNA damage response by regulating DNA damage ...

Specific binding of the methyl binding domain protein 2 at the BRCA1-NBR2 locus [PDF]

, 1996
The methyl-CpG binding domain (MBD) proteins are key molecules in the interpretation of DNA methylation signals leading to gene silencing. We investigated their binding specificity at the constitutively methylated region of a CpG island containing the ...

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).
