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.

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.

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.

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.

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).

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.

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.

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.

New breast cancer genes detected using cutting edge technology

Scientists in the UK say they have detected four new genes believed to be involved in the development of breast cancer.

Protein called cyclin D1 disrupts BRCA1's normal role as a cancer inhibitor

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 are linked to genetic miscues, about half of which are linked to BRCA1.

Harmful chemicals may reprogram gene response to estrogen

New research shows that exposure to harmful chemicals and drugs during critical developmental periods early in life may actually "reprogram" the way certain genes respond to the female hormone estrogen. This genetic reprogramming may determine whether people with a genetic predisposition for a disease actually develop the disease.

Environment factors can interact with genetics to increase disease risk

31 May 2005

Exposure to pharmaceutical estrogen during fetal development can permanently "reprogram" tissue in a way that determines whether tumors will develop in adulthood

Researchers at The University of Texas M. D. Anderson Cancer Center may have uncovered the reason why some people who are genetically predisposed to hormone-dependent cancers develop the disease as an adult, while others who are similarly susceptible don't.

Combined MRI and mammography more effective at detecting breast cancer in high risk women

Annual screening, using magnetic resonance imaging (MRI) and X-ray mammography, is the best way to detect breast cancer in women that have a high genetic risk of the disease, according to a study published online by The Lancet.

New gene linked to familial cancer

Scientists have identified a new gene that appears to be linked to a small but significant percentage of familial cancer cases – as well as seemingly randomly occurring malignancies.

Reducing expression of a gene called BRCC36 makes breast cancer cells more responsive to ionizing radiation

The research was presented today at the 96th Annual Meeting of the American Association for Cancer Research (AACR) in Anaheim, Calif. BRCC36 directly interacts with the BRCA1 protein. Almost all invasive breast cancer cells have elevated BRCC36 levels compared to normal breast milk-duct cells.
