Scientists have tracked down the biological trigger that gives rise to Van Buchem disease

...a hereditary, disfiguring bone disorder that can cause blindness and deafness. The findings provide insight into long-range gene regulation and could lead to new treatments for osteoporosis and other crippling bone disorders.

High exposure to the sun halves risk of prostate cancer

Cancer researchers in the U.S. say that high exposure to the sun halved the risk of prostate cancer in men participating in a U.S. trial.

Aortic disease difficult to diagnose

Aortic disease kills nearly 15,000 people in the United States each year, but the rarity and complexity of this deadly disorder make accurately diagnosing it difficult for doctors in the health-care trenches, University of Florida researchers have found.

Jumping genes help detemine uniqueness of individual brains

Scientists at the Salk Institute for Biological Studies may have found one explanation for the puzzling variety in brain organization and function: mobile elements, pieces of DNA that can jump from one place in the genome to another, randomly changing the genetic information in single brain cells.

New research shows that genes exert powerful effect on sexual behavior

New research has shown that the manipulation of a single gene in female fruit flies can make their sexual behavior resemble that of males, in a study that demonstrates the power of individual genes and the profound impact of genetics on complex sexual behavior.

Report on Hispanics and genes, culture, and medicines highlights the rise of individualized medicine

"The FDA's review today of BiDil could make it the first drug approved specifically for African Americans and marks the end of 'one-size-fits-all' medicine," said Dr. Jane L. Delgado, President and CEO of the National Alliance for Hispanic Health (the Alliance), the nation's leading Hispanic health advocacy group.

Exposure to sunlight may decrease the risk of prostate cancer

In the largest such study to date, a research team from three cancer centers measured sunlight exposure in men and found that increased exposure to sunlight may decrease the risk of prostate cancer.

Arteries bio-engineered from elderly cells

Researchers from Duke University's Medical Center and Pratt School of Engineering have demonstrated that they can grow new human blood vessels from cells taken from patients who especially need such assistance – older adults with cardiovascular disease.

Two common gene variations are associated with the risk for developing chronic kidney disease

Two common gene variations are associated with the risk for developing chronic kidney disease, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health and other institutions. One variant increases risk and the other decreases risk with a similar effect in whites, African-Americans, diabetic and non-diabetic individuals.

Causes, consequences and clinical implications of alcohol-related brain shrinkage

Previous studies have demonstrated that the brains of alcoholics are smaller, lighter and "shrunken" when compared to nonalcoholic brains.

Researchers may be on the verge of exploiting the vulnerabilities of a virus that causes cervical cancer

Researchers may be on the verge of exploiting the vulnerabilities of a virus that causes cervical cancer, thanks to a newly developed technique that enables scientists to mass-produce human papillomavirus (HPV) in the laboratory.

Research accelerates the search for an effective cancer vaccine

By devising a novel way to package the genome of a common human tumor virus - the virus that causes common warts, genital warts and that is implicated in prevalent cancers - scientists have paved the way for making the pathogen far more accessible to biomedical science.

Circadian clock gene also plays pivotal role in drug addiction

The gene that regulates the body's main biological clocks also may play a pivotal role in drug addiction, researchers at UT Southwestern Medical Center have found.

Novel and more effective way of testing which gene mutations cause cancer

Often cancer research goes like this: study cancerous cells in a lab dish, find mutations that appear in many of the samples, develop drugs to target proteins made by the mutated genes, and voila, new chemotherapy drugs are born. Or at least that's the hope.

Researchers discover how microRNA are involved in the development of heart muscle

Researchers at UT Southwestern Medical Center have discovered how a small molecule of RNA called microRNA - a chemical cousin of DNA - helps fine tune the production of a key protein involved in the early development of heart muscle.

Bio-engineered skin provides clues to melanoma development

When it comes to the deadly skin cancer melanoma, studying functional tissue rather than cell lines may better provide insight into the disease's development, according to new research from a Howard Hughes Medical Institute predoctoral fellow at Stanford University School of Medicine.

Genetic variations predispose Mexican Americans to insulin resistance

Although numerous studies have shown that low-grade inflammation is linked to heart disease and diabetes, more recent studies have shown that inflammation plays a role in insulin resistance, a syndrome that leads to diabetes and heart disease and affects about one in four adults in the United States.
