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.

New insight into pathogenic mechanisms underlying basal-like breast cancers

Basal-like breast cancers (BLC) are highly aggressive tumors with a relatively poor prognosis that account for approximately 15% of sporadic human breast cancer.

Broccoli, cauliflower and cabbage help repair damaged DNA

Need another reason to eat your vegetables? New research shows that some of them contain chemicals that appear to enhance DNA repair in cells, which could lead to protection against cancer development, say Georgetown University Medical Center researchers.

Non-BRCA1/2 hereditary breast cancer linked to new cancers

The risk for a new cancer in the unaffected breast substantially increases in women diagnosed with unilateral, hereditary (non-BRCA1/2) breast cancer, according to a new study by researchers working at Karolinska Institutet in Stockholm, Sweden.

BRCA1 gene inhibits estrogen and progesterone

It's been known that the breast cancer susceptibility gene BRCA1 regulates use of estrogen in breast and other cells, but now researchers at Georgetown University Medical Center have discovered that it also controls activity of a second sex steroid hormone, progesterone.

A good year for breast cancer detection and treatment

It was a good year in women’s health, notably breast cancer treatment and detection. The December issue of Mayo Clinic Women’s HealthSource hails these important advances of 2005.

Breast cancer survival rate boosted by radiotherapy

According to a new study breast cancer patients who have radiotherapy after breast-conserving surgery have a lower risk of a recurrence of the disease and a better chance of beating the illness.

Gene mapping project promises new targeted cancer therapies

Government researchers in the United States have this week launched a pilot project to find all the little genetic changes that cause cancer in the hope it will lead to a whole new world of targeted cancer therapy.

Women satisfied with contralateral prophylactic mastectomy

Mayo Clinic researchers report that most women who have a contralateral (opposite to cancerous breast) prophylactic mastectomy (CPM) are satisfied and would elect this procedure again. Satisfaction with CPM was studied an average of 10 years after the procedure was done. The findings were published online Oct. 3 in the Journal of Clinical Oncology.

Access to genetic counseling and testing are an important part of cancer control

Ten years after the identification of the first breast cancer susceptibility genes so few high-risk minority women have received genetic counseling or testing that the standard methods of calculating risk have not been validated in these groups and the results of genetic testing can still produce surprises.

Data supports use of personal and family history of breast cancer, ovarian cancer, or both in making clinical decisions

African American women at high-risk of breast cancer have genetic mutations that would make genetic testing feasible, according to a study in the October 19 issue of JAMA: The Journal of the American Medical Association.

18 Oct 2005

Simple, fast and effective method of detecting a large number of patients at high risk for hereditary breast/ovarian cancer

One in five women diagnosed with breast or ovarian cancer who seek mammography have a family history of cancer that suggests they may harbor known cancer-causing gene mutations.

26 Sep 2005

Questionnaire helps identify women who have inherited genetic mutations that increase their risk for breast or ovarian cancer

A simplified way for patients to report and update their family medical histories could help identify women who have inherited genetic mutations that increase their risk for breast or ovarian cancer.

26 Sep 2005

Increased ovarian cancer risk not linked to cancer family history

Women with a strong family history of breast cancer but who don't have breast cancer genetic mutations can now be reassured that they are not at increased risk for ovarian cancer, according to a new study by researchers at Memorial Sloan-Kettering Cancer Center (MSKCC).

21 Sep 2005

Testing for specific breast cancer genes unadvisable if no family history of disease exists

According to the Preventive Services Task Force in the U.S., routine testing for mutations in the BRCA1 and BRCA2 genes, which have been linked to breast and ovarian cancer, are not advised unless women have a family history of the disease.

7 Sep 2005

New recommendations for screening for BRCA1 and BRCA2 gene mutations

The United States Preventive Services Task Force issues new recommendations for screening for BRCA1 and BRCA2 gene mutations in the Sept. 6, 2005, issue of Annals of Internal Medicine.

Scientists help narrow the search for BRCA1 carriers

Cancer Research UK scientists have identified a new test which may help narrow the search for breast cancer patients likely to carry the faulty BRCA1 gene.

State-of-the-art portable biosensing device based on micro and nanotechnologies

A state-of-the-art portable biosensing device based on micro- and nanotechnologies will empower doctors to rapidly and accurately forewarn patients of their genetic risk of developing diseases such as cancer.

First proof of how the rare disorder Fanconi anemia causes chromosomal instability

The scientists found a gene mutation not previously known to be related to Fanconi anemia, and they say that BRIP1 is the first gene associated with the disease whose protein has a known function.

Losing weight cuts breast cancer risk

An international team of scientists has found that young women who carry a breast cancer gene, can reduce their risk of the disease by up to 65% by attaining a healthy bodyweight.

21 Aug 2005

Study results reaffirm cyclin D1 as a candidate target for molecular therapeutic control of breast tumor development

For about a decade, scientists have recognized that many cases of hereditary breast cancer result from a mutation of a specific gene called BRCA1, which, in its normal state, helps keep tumor formation in check. About five to 10 percent of breast cancer cases arise from these genetic miscues, about half of which are linked to the abnormal functioning of BRCA1.
