Revolutionary therapy slows tumor growth in advanced breast cancer
The new drug olaparib has antitumour activity in carriers of the BRCA1 or BRCA2 gene mutations who have advanced ovarian or breast cancer, according to the findings of two proof-of-concept trials. Together with previous findings, ...

Researchers identify a new breast and ovarian cancer susceptibility gene
A group of researchers report evidence unambiguously implicating the gene RAD51C in susceptibility to breast and ovarian cancer. This gene normally plays a role in DNA repair. By screening RAD51C in unrelated individuals ...

Pathways that Can Repair Brca1 Cancer Gene Mutation Clarified in Mice
(PhysOrg.com) -- In a new study in mice, scientists have compensated for mutations in the Brca1 gene that can lead to cancer by deleting a second gene, which then lessens the probability of cancer. Mice Brca1-associated mammary ...

Only women with Western Swedish breast cancer gene run higher risk of ovarian cancer
Previous research has shown that women with breast cancer are more likely than other women to develop ovarian cancer, but now researchers from the Sahlgrenska Academy at the University of Gothenburg, Sweden, have shown that ...

BRCA1
BRCA1 ( /ˈbrækə/; breast cancer 1, early onset) is a human caretaker gene that produces a protein called breast cancer type 1 susceptibility protein, responsible for repairing DNA. The first evidence for the existence of the gene was provided by the King laboratory at UC Berkeley in 1990. The gene was later cloned in 1994 by scientists at Myriad Genetics.
BRCA1 is expressed in the cells of breast and other tissue, where it helps repair damaged DNA, or destroy cells if DNA cannot be repaired. If BRCA1 itself is damaged, damaged DNA is not repaired properly and this increases risks for cancers.
The protein encoded by the BRCA1 gene combines with other tumor suppressors, DNA damage sensors, and signal transducers to form a large multi-subunit protein complex known as the BRCA1-associated genome surveillance complex (BASC). The BRCA1 protein associates with RNA polymerase II, and through the C-terminal domain, also interacts with histone deacetylase complexes. Thus, this protein plays a role in transcription, DNA repair of double-stranded breaks ubiquitination, transcriptional regulation as well as other functions.
