As children transform into adults some of the genes involved in controlling their blood pressure change as well

The study of black and white identical and fraternal twins showed that changes in gene expression between ages 14 and 18 accounted for up to one third of the blood pressure variation that occurred by age 18, says Dr. Harold Snieder, genetic epidemiologist at the Medical College of Georgia.

Factor B and H genes found to play role in the development of age-related macular degeneration

A new study, led by researchers at Columbia University Medical Center, pinpoints the role that two genes - Factor H and Factor B - play in the development of nearly three out of four cases of age-related macular degeneration (AMD), a devastating eye disease that affects more than 10 million people in the United States.

Genome signature tagging used to quickly identify and distinguish between pathogens and harmless microbes

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a new, high-throughput technique for identifying the many species of microorganisms living in an unknown "microbial community."

Genetic background to ravages of obesity

Why do some overweight people stay healthy (apart from possible musculo-skeletal disorders) while obesity in other individuals leads to complications like diabetes and cardiovascular disease?

Orthopaedic medical device technologies that offer greater clinical benefits expected to succeed

Current users of medical device technologies for orthopaedic applications seek systems that offer maximum comfort while requiring minimum physical supervision. This is driving the market to continuously evolve technologies that use radically different approaches or make significant improvements to existing products.

Attaching new cytokine to neural stem cells derived from bone marrow kills brain tumor cells

Attaching a recently discovered cytokine to neural stem cells derived from bone marrow, researchers at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute have developed a tool to track and kill malignant brain tumor cells and provide long-term protection against their return.

Rhodium quinones promise better drugs

By combining a common organic compound with a rare metal, a team of Brown University chemists has created a new class of molecules that have potentially important applications for the pharmaceutical, chemical and energy industries.

FDA approves Rituxan (Rituximab)

Rituxan is the first treatment for RA that selectively targets immune cells known as CD20-positive B-cells. Through this unique mechanism of action, Rituxan may affect multiple pathways by which B-cells are believed to contribute to the initiation and development of RA.

Ancient DNA helps unearth potential hemophilia therapy

A cut can be life-threatening for people with hemophilia, whose bodies don't produce enough of a protein that prevents prolonged bleeding.

Cell-death mechanism linked to developmental and degenerative brain disorders

Conclusive evidence that neurodevelopmental disorders such as mental retardation and neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease and ataxias can be caused, at least in part, by specific gene defects that interfere with the electrical impulses of rapid-firing brain nerve cells called bursting neurons.

Research shows promise for the advancement of cancer and stem-cell research

The paper explains how proteins, known as epigenetic activators (such as Ash1 from the fruit fly Drosophila), bind to their target DNA and activate genes that determine what function a cell will have in the body.

Analysis of protein interactions dispels old notions of what's important about them

Discoveries made during the first large-scale analysis of interactions between proteins in our cells hold promise for identifying new genes involved in genetic diseases, according to researchers at Johns Hopkins and the Institute of Bioinformatics (IOB) in Bangalore.

Spinocerebellar ataxia and other neurodegenerative diseases might be treatable with drugs that alter the activity of potassium channels

For the first time, researchers have linked mutations in a gene that regulates how potassium enters cells to a neurodegenerative disease and to another disorder that causes mental retardation and coordination problems.

Taste genes may yield important information about who smokes and why they smoke

Recent research on the genetics of smoking has focused on genes that are thought to be related to nicotine metabolism, personality traits, and regulation of emotions.

Why people of African descent are more vulnerable to tuberculosis infection

A team of scientists has identified a cellular mechanism that may help explain the puzzle of why people of African descent are more susceptible to tuberculosis infection and why, once infected, they develop more severe states of the disease than whites.
