BRCA2 Gene News and Research

RSS

BRCA2 is a gene on chromosome 13 that normally helps to suppress cell growth. A person who inherits certain mutations (changes) in a BRCA2 gene has a higher risk of getting breast, ovarian, prostate, and other types of cancer.

Scientists discover why some breast cancers are drug resistant

Research by British scientists has revealed how cancer cells which have a faulty gene can become resistant to treatment.

Benefit of removal of the ovaries differs between women with BRCA1 and BRCA2 mutations

The surgical removal of the ovaries has been widely adopted as a cancer-risk-reducing strategy for women with either BRCA1 or BRCA2 mutations.

Cancer cells adapt using Darwin's 'survival of the fittest' principle to resist treatment

Scientists in London have discovered a new genetic mechanism which helps cancer cells survive by changing the way they respond to treatment.

BRCA1 and BRCA2 gene mutations and breast cancer

Breast cancer risk varies widely among women who are carriers of the BRCA1 and BRCA2 mutations, according to a new study published in the January 9, 2008, issue of the Journal of the American Medical Association (JAMA).

Ashkenazi ovarian cancer patients with BRCA mutations live longer than those with normal gene

Israeli investigators have found that Ashkenazi Jewish women with ovarian cancer who have mutations in the BRCA1 or BRCA2 genes lived significantly longer than Ashkenazi Jewish ovarian cancer patients without these mutations.

Men unaware of their cancer risk when female relatives test positive for BRCA mutation

Men whose mothers, sisters or daughters test positive for a cancer-causing gene mutation also have an increased risk of developing the disease but are unaware of that risk.

Most carriers of Fanconi anemia genes are not at a higher risk of cancer

For almost 50 years, Fanconi anemia has been associated with leukemia. Not just among those who have the genetic disorder but among their family members, whose genes, they were told, made them highly susceptible to a variety of malignancies.

Study shows how mutations in the BRCA1 gene lead to breast cancer

An international team of researchers led by Columbia University Medical Center's Herbert Irving Comprehensive Cancer Center and Sweden's Lund University has, for the first time, revealed how mutations in the BRCA1 gene lead to breast cancer.

Network approach finds potential breast cancer susceptibility gene

Like a crossword-puzzle solver who uses the letters in some answers to figure out others, researchers at Dana-Farber Cancer Institute and an international group of collaborators have used data on genes involved in inherited forms of breast cancer to identify a gene linked to non-hereditary cases of the disease.

HMMR gene emerges as a key player in breast cancer

Researchers in a multicenter international study have identified a new gene that, if mutated, may increase a woman's risk of breast cancer by more than a third.

RecA family recombinases repair DNA damages

A biochemistry research team led by Dr. Andrew H.-J. Wang and Dr. Ting-Fang Wang at the Institute of Biological Chemistry, Academia Sinica(IBCAS), has discovered that the RecA family recombinases function as a new type of rotary motor proteins to repair DNA damages.

Eight things you need to know about ovarian cancer

Ovarian cancer doesn't get the kind of attention breast cancer gets. It's not as common, and because survival rates are poor, it does not produce an army of survivors to raise awareness.

Discovery suggests location of genes for breast density, a strong risk factor for breast cancer

Studying the DNA of 889 people, gene hunters at the Mayo Clinic and H. Lee Moffitt Cancer Centers have identified a region on chromosome 5p that is significantly associated with dense breast tissue, a known risk factor for breast cancer.

Breast cancer prevention practices vary across Canada

Breast cancer preventive practices for Canadian women carrying the cancer gene vary across the country, says University of Toronto research, and many women are not taking advantage of the options available.

16 Aug 2007

FOXP3 gene found to be involved in breast cancer

Researchers at the University of Michigan Comprehensive Cancer Center have identified a gene linked to the development of an aggressive form of breast cancer.

Chemotherapy may benefit all women with a BRCA1 mutation

Breast cancer patients who possess one of the so-called "breast cancer" or BRCA genetic mutations do not have a higher risk of dying than patients with no BRCA mutations, according to a detailed study by researchers at the Technion-Israel Institute of Technology and the University of Toronto.

12 Jul 2007

Magnetic resonance spectroscopy for breast cancer

The American Cancer Society recently issued new recommendations for women with a higher risk of developing breast cancer, including those with a family history of breast or ovarian cancer, and those who may carry genetic mutations (BRCA1 or BRCA2) that make them more likely to develop the disease.

DNA repair by Brca2 prevents medulloblastoma

St. Jude investigators have gained some of the first major insights into how certain genes known to prevent cancer also guide the nervous system's normal development before birth and during infancy by repairing DNA damage.

23 Jun 2007

Size of family appears to affect breast cancer risk

Researchers have found that the probability of the breast cancer gene mutation BRCA among women with a history of breast cancer is greater when the number of older, female relatives in the family is smaller, according to a study in the June 20 issue of JAMA: The Journal of the American Medical Association.
