BRCA1-mediated repression of select X chromosome genes [PDF]

Journal of Translational Medicine, 2004
Recently BRCA1 has been implicated in the regulation of gene expression from the X chromosome. In this study the influence of BRCA1 on expression of X chromosome genes was investigated.

The Effects of BRCA1 and BRCA2 Promoter Methylation on Clinicopathological Characteristics and Clinical Outcomes in HGSOC [PDF]

Cells
Ovarian cancer is a highly lethal disease. Tumors with a deficiency in the homologous recombination repair pathway (HRD) resulting from mutations in BRCA1/2 genes have a favorable response to platinum-based chemotherapy and targeted therapy with PARP ...

Differentially expressed genes and key molecules of BRCA1/2-mutant breast cancer: evidence from bioinformatics analyses [PDF]

PeerJ, 2020
Background BRCA1 and BRCA2 genes are currently proven to be closely related to high lifetime risks of breast cancer. To date, the closely related genes to BRCA1/2 mutations in breast cancer remains to be fully elucidated.

Exome Sequencing in BRCA1-2 Candidate Familias: The Contribution of Other Cancer Susceptibility Genes

Frontiers in Oncology, 2021
Hereditary Breast and Ovarian Cancer (HBOC) syndrome is a condition in which the risk of breast and ovarian cancer is higher than in the general population.

Clinicopathological characteristics of -associated breast cancer in Asian patients [PDF]

Journal of Pathology and Translational Medicine, 2020
BRCA1/2 germline mutations account for the majority of hereditary breast cancers. Since the identification of the BRCA genes, several attempts have been made to define the clinicopathological characteristics of BRCA-associated breast cancer in comparison

Correlation between the number of false positive variants and the quality of results using Ion Torrent PGM™ sequencing to screen BRCA genes

Biomédica: revista del Instituto Nacional de Salud, 2021
Introduction: Next Generation Sequencing (NGS) is cost-effective and a faster method to study genes, but its protocol is challenging. Objective: To analyze different adjustments to the protocol for screening the BRCA genes using Ion Torrent PGM ...

BRCA1 Represses Amphiregulin Gene Expression [PDF]

Cancer Research, 2010
Abstract BRCA1, the breast cancer- and ovarian cancer-specific tumor suppressor, can be a transcriptional repressor or a transcriptional activator, depending on the promoter context. To identify the genes activated or repressed by BRCA1, we have analyzed microarray results from cells depleted of BRCA1 and revealed a number of genes ...

Histopathological characterization of carcinoma breast with BRCA1/2 sequence variation in a Tertiary Care Center in Kerala, South India

Biomedical and Biotechnology Research Journal, 2022
Background: Hereditary breast cancers constitute around 5%–10% of all breast cancers. The most commonly mutated genes in hereditary breast and ovarian cancer syndrome are the BRCA1 and BRCA2 genes.

Mutant BRCA1 genes antagonize phenotype of wild-type BRCA1 [PDF]

Oncogene, 2001
Unregulated expression of wild-type BRCA1 (wtBRCA1) confers an altered phenotype in cultured human prostate cancer cells, characterized by chemosensitivity, susceptibility to apoptosis, decreased DNA repair activity, and alterations of key cell regulatory proteins.

BRCA1 gene in breast cancer [PDF]

Journal of Cellular Physiology, 2003
AbstractThe BRCA1 gene was identified and cloned in 1994 based its linkage to early onset breast cancer and breast‐ovarian cancer syndromes in women. While inherited mutations of BRCA1 are responsible for about 40–45% of hereditary breast cancers, these mutations account for only 2‐3% of all breast cancers, since the BRCA1 gene is rarely mutated in ...
