BRCA1 Gene News and Research

RSS

BRCA1 is a gene on chromosome 17 that normally helps to suppress cell growth. A person who inherits certain mutations (changes) in a BRCA1 gene has a higher risk of getting breast, ovarian, prostate, and other types of cancer.

BRCA1 gene mutation increases breast cancer risk: Research

Individuals with disrupting mutations in the BRCA1 gene are known to be at substantially increased risk of breast cancer throughout their lives. Now, discoveries from an international research team led by Mayo Clinic researchers show that some of those persons may possess additional genetic variants that modify their risk. These new findings enhancing individualized medicine appear in the current Nature Genetics.

Scientists discover new genetic variants, pave way for early detection of ovarian cancer

An international consortium of scientists has discovered new genetic variants in five regions of the genome that affect the risk of ovarian cancer in the general population, according to two separate studies published today (Sunday), online in Nature Genetics.

Luminal intermediate cells impact basal-like breast cancer origin: Research

New research uncovers a case of mistaken identity that may have a significant impact on future breast cancer prevention and treatment strategies. The study, published by Cell Press in the September 3rd issue of the journal Cell Stem Cell, suggests that despite their "stem cell-like" characteristics, most aggressive breast tumors are not derived from normal mammary gland stem cells.

African ancestry associated with triple-negative breast cancer: Study

A new study finds that African ancestry is linked to triple-negative breast cancer, a more aggressive type of cancer that has fewer treatment options.Researchers at the University of Michigan Comprehensive Cancer Center found that, among women with breast cancer, 82 percent of African women were triple negative, 26 percent of African-Americans were and 16 percent of white Americans were.

Lawsuit to be launched over breast cancer gene patent

BRCA1 and BRCA2 are two genes that have been identified to hold a key to women’s susceptibility to get breast or ovarian cancer. Changes also known as mutations in these genes are significant in women who go on to develop breast or ovarian cancer. Melbourne-based company Genetic Technologies Limited (GTL) has the exclusive license from American biotechnology company Myriad Genetics to carry out testing for the genes in Australia. Myriad holds a patent for these genes.

Mutation in BRCA1 tumor suppressor gene helps develop breast, ovarian cancer: Study

Studies have well established that women who harbor a mutation in the BRCA1 tumor suppressor gene are at greater risk for developing breast and ovarian cancers. Less known is information on other molecular events that may impact cancer formation in cells having a BRCA1 mutation. Investigators from The Cancer Institute of New Jersey and a number of major cancer centers in Europe have identified the role a key protein plays in helping cells with mutant BRCA1 genes to survive.

Discovery of new genetic clues to breast cancer

Researchers at Cambridge University have identified five genetic clues for women who have a family history of breast cancer. The study brings up the number of common genetic variations linked to increased risk of breast cancer in women to 18. The study was published in Nature Genetics.

Major study shoots for personalized breast cancer drugs

Mutations in BCRA1 and BCRA2 genes are mainly associated with increased risk of breast cancer in women. Recently many other genetic variants have been found to be associated with breast cancer.

Combination of MRI and mammography reduces mortality rate in high-risk women

Annual breast cancer screening with both mammography and magnetic resonance imaging (MRI) is likely to be a cost-effective way to improve life expectancy in women with an increased risk of breast cancer, according to a new study published in the March issue of Radiology.

Findings reveals 'limpet-like' proteins can play a key role in DNA repair

UK scientists have found that a crafty family of 'limpet-like' proteins can play a crucial role in repairing DNA damage - according to two research papers published in Nature today (Wednesday). These findings could pave the way to the design of new anti-cancer drugs which target this process.

Possible link between presence of breast cancer genes and infertility discovered

A New York Medical College physician who specializes in restoring or preserving fertility in female cancer patients has discovered a possible link between the presence of breast cancer genes and infertility.

Study examines the association of BRCA1 gene, infertility and breast/ovarian cancer

In a study published online this week in the leading cancer journal, Journal of Clinical Oncology, Westchester Medical Center Physician Dr. Kutluk Oktay, MD, Director, Division of Reproductive Medicine & Infertility concluded that mutations in the BRCA1 gene (gene associated with early onset breast cancer) are associated with early diminishment of egg reserve.

New breast reconstruction surgery for women

Since her teens, Jennifer Jablon had watched family members deal with breast cancer during their 40s, 50s, and 60s. She wondered whether it would be her fate too.

Genetic mutation implicated in breast and ovarian cancers could also have a role in causing heart failure: Study

A genetic mutation implicated in breast and ovarian cancers could also have a role in causing heart failure, according to a new study reported at the 95th annual Clinical Congress of the American College of Surgeons.

Many women at high risk for breast or ovarian cancer choose surgery as a precautionary measure

Many women at high risk for breast or ovarian cancer are choosing to undergo surgery as a precautionary measure to decrease their cancer risk, according to a report in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Genetic testing for breast or ovarian cancer risk may be greatly underutilized

Although a test for gene mutations known to significantly increase the risk of hereditary breast or ovarian cancer has been available for more than a decade, a new study finds that few women with family histories of these cancers are even discussing genetic testing with their physicians or other health care providers.

American Civil Liberties Union challenges breast cancer gene patents

The American Civil Liberties Union and the Public Patent Foundation at Benjamin N. Cardozo School of Law (PUBPAT) filed a lawsuit today charging that patents on two human genes associated with breast and ovarian cancer stifle research that could lead to cures and limit women's options regarding their medical care.

Discovery of new protein important in breast cancer gene's role in DNA repair

For years, researchers have known that under normal conditions, the breast cancer protein BRCA1 orchestrates the repair of damaged DNA, but the details of just how BRCA1 moves to the damaged site and recruits the right nuclear repairmen for DNA restoration remains a mystery.
