Gene could spell new chapter in fight against gout

Researchers have found why some people are more susceptible to gout than others. The scientists looked at the genetic codes of more than 12,000 people after identifying a gene linked to uric acid levels in the blood.

Improved method for genetically manipulating human embryonic stem cells

UC Irvine researchers have discovered a dramatically improved method for genetically manipulating human embryonic stem cells, making it easier for scientists to study and potentially treat thousands of disorders ranging from Huntington's disease to muscular dystrophy and diabetes.

The brain's melanocortin system points to new treatments for obesity and anorexia

The discovery of the brain's so-called melanocortin system and its central role in controlling appetite has paved the way for entirely new possibilities for treating obesity and anorexia.

Research helps explain why some flu strains cause major pandemics and others lead to seasonal epidemics

The exchange of genetic material between two closely related strains of the influenza A virus may have caused the 1947 and 1951 human flu epidemics, according to biologists.

Predictors for sickle-cell-anemia complications

Researchers at UT Southwestern Medical Center have determined that the level, or saturation, of oxygen in blood could be used to identify children with sickle cell anemia who are at an increased risk of stroke.

Researchers discover molecular pathway in blood vessels that controls blood pressure and vascular function

University of Iowa researchers have identified a molecular pathway in blood vessels that controls blood pressure and vascular function and may help explain why certain drugs for type II diabetes also appear to lower patients' blood pressure.

New potential drug target for atherosclerosis

A nuclear receptor protein, known for controlling the ability of cells to burn fat, also exerts powerful anti-inflammatory effects in arteries, suppressing atherosclerosis in mice prone to developing the harmful plaques, according to new research by scientists at the Salk Institute for Biological Studies and the Harvard School of Public Health.

Molecular alliance that sustains embryonic stem cell state

One of the four ingredients in the genetic recipe that scientists in Japan and the U.S. followed last year to persuade human skin cells to revert to an embryonic stem cell state, is dispensable in ES cells, thanks to the presence of a molecular alliance between a specific group of key proteins known as transcription factors, a research team led by the Genome Institute of Singapore (GIS) under the Agency for Science, Technology and Research (A*STAR) reports in the current issue of Nature Cell Biology.

Prader-Willi syndrome - new genetic clues

A new mouse model for a genetic cause of obesity has been developed by scientists at the Stanford University School of Medicine and Lucile Packard Children's Hospital.

Alcohol may increase blood pressure to a much greater extent than previously thought

Previous observational studies have reported that heavy alcohol intake is a risk factor for hypertension but such studies may be confounded by factors such as diet, smoking, exercise levels and socio-economic position.

Happiness in life and your genes

Happiness in life is as much down to having the right genetic mix as it is to personal circumstances according to a recent study.

Flat, non-polypoid colorectal neoplasms linked to colorectal cancer

Flat, non-polypoid colorectal neoplasms (NP-CRNs), which may be difficult to detect, appear to be relatively common and may have a greater association with cancer compared with the more routinely diagnosed type of colorectal polyps, according to a study in the March 5 issue of JAMA.

Genetic mutations involved in IGF-I signaling pathway influence life span

Mutations in genes governing an important cell-signaling pathway influence human longevity, scientists at the Albert Einstein College of Medicine of Yeshiva University have found.

Chemotherapy with chemoradiation for pancreatic cancer has small survival benefit

The addition of the drug gemcitabine with chemoradiation for the treatment of patients who had surgery for pancreatic cancer was associated with a survival benefit, although this improvement was not statistically significant, according to a study in the March 5 issue of JAMA.

Biologists discover parochial bacterial viruses

Biologists examining ecosystems similar to those that existed on Earth more than 3 billion years ago have made a surprising discovery: Viruses that infect bacteria are sometimes parochial and unrelated to their counterparts in other regions of the globe.
