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

open access: yesArchives 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.

DNA repair deficiency biomarkers and the 70-gene ultra-high risk signature as predictors of veliparib/carboplatin response in the I-SPY 2 breast cancer trial. [PDF]

open access: yes, 2017
Veliparib combined with carboplatin (VC) was an experimental regimen evaluated in the biomarker-rich neoadjuvant I-SPY 2 trial for breast cancer. VC showed improved efficacy in the triple negative signature.

Structure-Function Of The Tumor Suppressor BRCA1

open access: yesComputational 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.

PALB2 self-interaction controls homologous recombination. [PDF]

open access: yes, 2012
PALB2 is essential for BRCA2 anchorage to nuclear structures and for homologous recombinational repair of DNA double-strand breaks. Here, we report that the N-terminal coiled-coil motif of PALB2 regulates its self-association and homologous recombination.

An introspective update on the influence of miRNAs in breast carcinoma and neuroblastoma chemoresistance [PDF]

open access: yes, 2014
Chemoresistance to conventional cytotoxic drugsmay occur in any type of cancer and this can either be inherent or develop through time. Studies have linked this acquired resistance to the abnormal expression of microRNAs (miRNAs) that normally silence ...

In Vitro Enhanced Sensitivity to Cisplatin in D67Y BRCA1 RING Domain Protein

open access: yesBreast Cancer: Basic and Clinical Research, 2011
BRCA1 is a tumor suppressor protein involved in maintaining genomic integrity through multiple functions in DNA damage repair, transcriptional regulation, cell cycle checkpoint, and protein ubiquitination. The BRCA1-BARD1 RING complex has an E3 ubiquitin
