Scientists put ehrlichiosis under the genomic spotlight

Ehrlichiosis is no star of science. This emerging disease has an awkward name, vague flu-like symptoms, and a nasty habit of being caused by bacteria that live inside ticks and flatworms.

Dramatic metabolic differences in how people process drugs

A Medical College of Wisconsin study provides the strongest and most complete evidence to date of major changes occurring during human development in the types and levels of enzymes responsible for the disposition of drugs and environmental chemicals.

New method determines in a matter of hours exposure to a bioterrorism agents

Researchers at Walter Reed Army Institute of Research are developing a method to determine in a matter of hours if someone has been exposed to a bioterrorism agent just by looking at the pattern of active genes in that person's white blood cells.

Adjuvant hormonal therapy reduces contralateral breast cancer risk

The risk for a new cancer in the unaffected breast substantially increases in women diagnosed with unilateral, hereditary (non-BRCA) breast cancer, according to a new study.

Genetics of human muscular dystrophy

Various forms of human muscular dystrophy result from mutations in genes encoding proteins of the nuclear envelope. A new paper in the February 15th issue of G&D reveals how.

Purdue biologists visualize protein interaction that may initiate viral infection

Biologists at Purdue University have taken a "snapshot" of a Velcro-like protein on a cell's surface just after it attached to the dengue virus, a linkup thought to initiate the early stages of infection.

Advancing knowledge of diet-gene interactions

Josi Ordovas, PhD, director of the Nutrition and Genomics Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University joined more than eighty other leading researchers in the fields of nutrition and genetics to co-author a report outlining their strategy for maximizing the impact of nutrigenomics research on global poverty and health.

Hormone aldosterone linked to quality of hearing

Researchers have linked a hormone known to adjust levels of key brain chemicals to the quality of our hearing as we age. The more of the hormone that older people have in their bloodstream, the better their hearing is, and the less of the hormone, the worse their hearing is.

Brain scans may detect neurological decline in normal people

Brain scans may detect neurological changes in people who exhibit no outward signs of cognitive decline but who later develop dementia or mental impairment, according to the results of a new study led by researchers at the University of California, Berkeley.

Less is more hypothesis - gene loss may explain unique human traits

Humans and chimps share most of their genes, yet they differ dramatically in many ways - their walk, the sizes of their brains and their capacities for speech and language, for example.

Causes of type 1 diabetes

Scientists are casting a wide, tightly woven net with the goal of catching the causes of type 1 diabetes.

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.

X chromosome dosage compensation proven in germ cells

X chromosome dosage compensation does occur in germ cells. A study published today in the open access journal Journal of Biology reveals that expression of the genes on the X chromosome is doubled in Drosophila germ cells to compensate for the missing second X chromosome.

British woman loses Herceptin court battle

A mother of three in the UK suffering from the early-stage of an aggressive form of breast cancer, has lost her high court battle to force her health authority to pay for the potentially life-saving drug Herceptin.

Study provides animal model of depression

A Florida State University scientist used a gene transfer technique to block the expression of a gene associated with clinical depression in a new study of mice that could lead to better treatment of human beings with this condition.

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.

Gene therapy cures depressed mice

Researchers in the U.S. say that deleting a specific gene in the brain of mice that have been conditioned to be depressed, has the same effect as antidepressants.

Protein associated with growth of tumors may prevent the spread of cancer

A protein associated with the growth of head and neck tumors may be a tumor suppressor that could prevent the spread of cancer when it is expressed above normal levels, according to a study published in the Journal of the National Cancer Institute (JNCI).
