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.

Genomic landscape of advanced prostate cancer patients with BRCA1 versus BRCA2 mutations as detected by comprehensive genomic profiling of cell-free DNA

Frontiers in Oncology, 2022
BRCA1-mutated prostate cancer has been shown to be less responsive to poly (ADP-ribose) polymerase (PARP) inhibitors as compared to BRCA2-mutated prostate cancer. The reason for this differential response is not clear.

Multi-gene panel testing for hereditary cancer predisposition in unsolved high-risk breast and ovarian cancer patients. [PDF]

, 2017
PurposeMany women with an elevated risk of hereditary breast and ovarian cancer have previously tested negative for pathogenic mutations in BRCA1 and BRCA2. Among them, a subset has hereditary susceptibility to cancer and requires further testing.

Use of Gene Expression Profiles of Peripheral Blood Lymphocytes to Distinguish Mutation Carriers in High Risk Breast Cancer Families

Cancer Informatics, 2009
Mutations in two major genes, BRCA1 and BRCA2 , account for up to 30% of families with hereditary breast cancer. Unfortunately, in most families there is little to indicate which gene should be targeted first for mutation screening, which is labor ...

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 ...

Homologous Recombination Abnormalities Associated With Mutations as Predicted by Machine Learning of Targeted Next-Generation Sequencing Data

Breast Cancer: Basic and Clinical Research, 2023
Background: Homologous recombination deficiency (HRD) is the hallmark of breast cancer gene 1/2 ( BRCA1/2 )-mutated tumors and the unique biomarker for predicting response to double-strand break (DSB)–inducing drugs.

Complex-based analysis of dysregulated cellular processes in cancer [PDF]

, 2014
Background: Differential expression analysis of (individual) genes is often used to study their roles in diseases. However, diseases such as cancer are a result of the combined effect of multiple genes.

BRCA1-BARD1 regulates transcription through modulating topoisomerase IIβ

Open Biology, 2021
RNA polymerase II (Pol II)-dependent transcription in stimulus-inducible genes requires topoisomerase IIβ (TOP2B)-mediated DNA strand break and the activation of DNA damage response signalling in humans.

Mutations in pathways depending on BRCA1 and BRCA2 may increase cancer risks from an environmental carcinogen [PDF]

, 2011
Recently, the President’s Cancer Panel [2008-2009] protested that preventive action is not taken when uncertainty exists about potential harm from a chemical, because the US regulatory approach demands that a hazard be incontrovertibly ...

Role of Single Nucleotide Polymorphisms in BRCA1 and BRCA2 Genes Relative to Previous Studies in Pakistan in the Prognosis of Breast Cancer [PDF]

Journal of Liaquat National Hospital
Breast cancer is a complex disease characterized by a myriad of genetic alterations. Single nucleotide polymorphisms are particularly relevant due to small allelic variations.
