Mutation that protects against HIV infection may raise risk of West Nile virus illness
People who lack a cell surface protein called CCR5 are highly resistant to infection by HIV but may be at increased risk of developing West Nile virus (WNV) illness when exposed to the mosquito-borne virus. view more (2006-01-17)
Use of breast MRI can be cost-effective for some women at high-risk of breast cancer
A computer model simulation suggests that adding breast MRI screening may be cost-effective for women of certain ages who carry BRCA1 and BRCA2 gene mutations. view more (2006-05-24)
Breast cancer patients with high risk gene diagnosed 6 years earlier than generation before
Women with a deleterious gene mutation are diagnosed with breast cancer six years earlier than relatives of the previous generation who also had the disease and/or ovarian cancer, according to new research from The University of Texas M. D. Anderson Cancer Center. view more (2009-10-12)
Researchers develop mouse model of autism spectrum disorders
Howard Hughes Medical Institute researchers have genetically engineered mice that harbor the same genetic mutation found in some people with autism and Asperger syndrome. view more (2007-09-07)
Researchers discover gene mutation thought to control energy levels
This study focused on the gene for AMPK (adenosine monophosphate-activated protein kinase), which controls the amount of energy in our cells by becoming active when fuel stores start to deplete, such as during exercise. view more (2007-09-19)
Women with BRCA mutation, or worry, most likely to undergo prophylactic mastectomy
Women at increased risk for breast cancer because of the genetic BRCA mutations are more likely to think a prophylactic mastectomy is the best way to reduce their risk for the disease, compared to other women who are at high risk, according to researchers at The University of Texas M. D. Anderson Cancer Center. view more (2009-03-09)
APL regulates vascular tissue identity in Arabidopsis
Plants have a conductive tissue, phloem, for transporting sugars and hormones to non-green parts after photosynthesis. Phloem has two basic cell types, enucleate sieve elements (SE) and companion cells (CC). Scientists from the University of Helsinki have developmentally analyzed the process of phloem development in Arabidopsis plant and... view more... (2003-11-13)
Regulatory T cells require WASp if they are to prevent self-destruction
In humans, mutation of the gene encoding a protein known as WASp leads to susceptibility to infections and systemic autoimmunity. view more (2007-01-12)
Nursing study concludes few Ontario women with invasive ovarian cancer referred for genetic testing of breast cancer genes
An Ontario study of 491 women with invasive ovarian cancer found only a small proportion, 19%, were referred for genetic testing of BRCA1 and BRCA2, the breast cancer genes, which means family members are not informed of their cancer risk. view more (2008-12-05)
Genetics and lifestyle interact to increase risk for age-related blindness
The interplay between genetic predisposition and exposure to modifiable risk factors can multiply the risk for age-related macular degeneration. view more (2007-01-09)
Stabilizing cancer-fighting p53 can also shield a metastasis-promoter
Efforts to protect the tumor-suppressor p53 could just as easily shelter a mutant version of the protein, causing cancer cells to thrive and spread rather than die, according to research by scientists at The University of Texas M. D. Anderson Cancer Center reported in the current issue of the journal Genes and Development. view more (2008-05-23)
Testicular tumors may explain why some diseases are more common in children of older fathers
A rare form of testicular tumour has provided scientists with new insights into how genetic changes (mutations) arise in our children. view more (2009-10-26)
Identifying cancer genes - will it really lead to better treatment?
Copenhagen, Denmark: A systematic trawl through the human genome looking for the abnormalities that drive cancer is already producing promising results, a scientist told ECCO 12 - The European Cancer Conference in Copenhagen today (Tuesday 23 September). Dr. Michael Stratton, Director of the Cancer Genome Project at the Wellcome Trust Sanger... view more... (2003-09-21)
Breast Cancer Gene Reviewed
PRESS CONFERENCE - 0930 H Thursday 26 September at Cancer Research UK, 44 Lincoln's Inn Fields, London WC2A 3PX, UK; Further information from Cancer Research UK Press Office (see below). A review article in this week's issue of THE LANCET assesses the impact of BRCA1 gene mutations-known to be strongly associated with an increased risk of breast... view more... (2002-09-25)
Closing in on lethal heart rhythm in young athletes
Johns Hopkins experts on the genetics of a potentially lethal heart rhythm defect that runs in families and targets young athletes report they have greatly narrowed the hunt for the specific genetic mutations that contribute to the problem. view more (2006-09-08)
Scientists link another gene to degenerative blindness
Researchers have labored for decades to understand blindness-inducing neurodegenerative diseases such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP). view more (2006-01-19)
Mutant rats offer clues to medical mystery
A research project at Rice University has brought scientists to the brink of comprehending a long-standing medical mystery that may link cardiovascular disease, osteoporosis and perhaps even Alzheimer's disease. view more (2009-02-18)
Women often opt to surgically remove their breasts, ovaries to reduce cancer risk
Many women at high risk for breast or ovarian cancer are choosing to undergo surgery as a precautionary measure to decrease their cancer risk. view more (2009-08-06)
Bigger horns equal better genes
According to a team of international researchers, mature, male alpine ibex demonstrate a correlation between horn growth and genetic diversity. Past research studies have shown that greater genetic diversity correlates with a greater chance of survival. view more (2007-06-07)
Tiny, spontaneous gene mutations may boost autism risk
Tiny gene mutations, each individually rare, pose more risk for autism than had been previously thought, suggests a study funded in part by the National Institute of Mental Health, a component of the National Institutes of Health. view more (2007-03-16)
