Technology for analyzing gene expression must be standardized

Technology for analyzing gene expression must be standardized among laboratories and across platforms around the world to support this age of human genome exploration, an Oregon Health & Science University researcher says.

Protein TRPA1 essential for hearing also vital for pain perception

The same protein that "translates" sound into nerve signals to the brain and enables individuals to hear is also required for pain perception, researchers from Northwestern University Feinberg School of Medicine have found.

Researchers discover genetic trigger that plays a key role in cancer of the oesophagus

Cancer Research UK scientists at the University of Oxford have identified a gene which plays a key role in the development of cancer of the oesophagus by triggering changes in the oesophagus lining.

Activation of thermoreceptors mediates raw garlic's burning pungency

The worldwide popularity of garlic as a food ingredient and its therapeutic stature in folklore both stem in part from the distinctive pungency associated with its raw, uncooked state.

Bone loss reduced by blocking body's cannabis-like substances

British scientists have discovered that blocking the action of cannabis-like substances produced naturally by the body can reduce bone loss and they hope this finding will lead to new drugs to treat osteoporosis and other bone diseases.

More health benefits from green tea

Green tea appears to protect against cancer by affecting a "promiscuous" protein that pharmaceutical experts are already targeting in an effort to develop a new drug to stop the disease, scientists at the University of Rochester Medical Center have found.

Disabling gene defuses rheumatoid arthritis in mice

Scientists studying mice have identified a gene that allows immune cells known as neutrophils to protect themselves from the inflammatory chemicals they secrete.

Researchers to explore genome of disease-fighting fungus

A team of Texas Agricultural Experiment Station scientists will soon begin genome sequencing a disease-fighting fungus used to protect crops, which has implications for both agriculture and the pharmaceutical industry.

Discovery of a fundamental new route into cells may lead to new methods of drug delivery

Researchers from The University of Queensland’s Institute for Molecular Bioscience (IMB), and the Centre for Microscopy and Microanalysis used electron microscopy to uncover new structures, 100,000th of a mm in size, which are involved in the very first step of particle and nutrient uptake into cells.

A new approach to prevent cancer

Researchers at the University of Dundee have identified a way of inactivating a naturally occurring human protein, a development which could offer new routes to developing cancer prevention treatments.

Simple and efficient method for creation of novel protein functions in an existing protein scaffold

By designing a molecular bridge, scientists at the University of Illinois at Urbana-Champaign have forged a successful pathway through a complex ocean of barriers: They've changed the function of a protein using a co-evolution approach.

GM mice live longer and give hope for anti-aging treatments

U.S. scientists have produced genetically modified mice that live 20 per cent longer than normal and may have possibly discovered an approach to extending the human lifespan.

Scientists extend the lifespan of mice

Scientists at the University of Washington and their colleagues at other research centers have found a way to significantly extend the lifespan of mice while reducing the impact of the aging process. Their study, which will be published online by the journal Science on May 5, lends more credence to the free-radical theory of aging.

More repellents recommended in the fight against West Nile Virus

In an attempt to fight the West Nile virus U.S. health officials have recommended two more mosquito repellent ingredients, one of them a plant oil.

Use of agricultural insecticides linked to lasting neurological problems for farmers

New research shows that farmers who used agricultural insecticides experienced increased neurological symptoms, even when they were no longer using the products. Data from18,782 North Carolina and Iowa farmers linked use of insecticides, including organophosphates and organochlorines, to reports of reoccurring headaches, fatigue, insomnia, dizziness, nausea, hand tremors, numbness and other neurological symptoms. Some of the insecticides addressed by the study are still on the market, but some, including DDT, have been banned or restricted.

Pollutants appear to have an affect on sex chromosome

A team of researchers from Lund University in Sweden have found that exposure to a class of environmental pollutants can change the ratio of sperm carrying male and female chromosomes.

Potential for brain stem cells to be used to cure diabetes

Promising new research by US scientists has shown the potential for brain stem cells to be used to cure diabetes. The work by Stanford University researchers, though not yet ready to be tested on human patients, has shown promising results in animals.

Fickle enzyme helps protect, but also can promote heart failure

Enzymes that make the gas nitric oxide (NO) not only protect the heart from damage due to high blood pressure or a heart attack, but also promote heart failure through overgrowth and enlargement of the muscle tissue, say animal researchers at Johns Hopkins.

How Ebola virus infects cells - discovery

Ebola virus reproduction in laboratory-grown cells is severely hampered by enzyme-inhibiting chemicals, and these chemicals deserve further study as possible treatments for Ebola virus infections in humans, report scientists supported in part by the National Institute of Allergy and Infectious Diseases (NIAID).

Scientists have, for the first time, induced a state of reversible metabolic hibernation in mice

Scientists at Fred Hutchinson Cancer Research Center have, for the first time, induced a state of reversible metabolic hibernation in mice. This achievement, the first demonstration of "hibernation on demand" in a mammal, ultimately could lead to new ways to treat cancer and prevent injury and death from insufficient blood supply to organs and tissues.
