New lung cancer therapy with vaporized viral vector shows promise

A new lung cancer therapy employing a vaporized viral vector to deliver a cancer-inhibiting molecule directly to lung tissue shows early promise in mouse trials, according to researchers at the Ministry of Education, Science and Technology in Korea.

Genetic and environmental relations between insomnia and intrusive thinking

The genetic factors that cause increased sleep problems during times of stress seem to be the same as those that make people with intrusive and ruminative thoughts have a higher prevalence of insomnia, according to a research abstract that will be presented on Tuesday, June 9, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies.

Discovery 'significant step' in understanding leukaemia drug resistance

Scientists have pinpointed an enzyme responsible for breaking down and inactivating a key childhood leukaemia drug, which could help to explain why around 20 per cent of patients do not respond to therapy. Their findings are published in the Journal of Clinical Investigation.

New research looks at the role of geography in human adaptation

New research indicates that natural selection may shape the human genome much more slowly than previously thought. Other factors -- the movements of humans within and among continents, the expansions and contractions of populations, and the vagaries of genetic chance - have heavily influenced the distribution of genetic variations in populations around the world.

Greater oversight needed in sharing of genetic information online

With just $399 and a bit of saliva in a cup, consumers can learn about their genetic risk for diseases from breast cancer to diabetes. Now, thanks to social networking sites set up by personal genomics companies, they can also share that information with family, friends and even strangers on the Internet.

Rhes protein responsible for brain cell damage in Huntington disease

Johns Hopkins brain scientists have figured out why a faulty protein accumulates in cells everywhere in the bodies of people with Huntington's disease (HD), but only kills cells in the part of the brain that controls movement, causing negligible damage to tissues elsewhere.

Cigarette smoking does not affect everyone in same way

Cigarette smoking induced COPD, or chronic obstructive pulmonary disease, is a disease that results in severe breathing difficulty. According to World Health Organization (WHO) it is the fourth leading killer worldwide. However the mechanisms responsible for some smokers developing COPD and others evading the disease have not been well understood.

Study gives clues to how ultra-rare adrenocortical cancer forms

At the ends of chromosome are special pieces of DNA called telomeres. Think of it as the little tip that caps off a shoelace. The telomeres send signals to the cells to let them know it's the end point, not a break that should be repaired.

Discovery of new genetic immune disorder in children

Your immune system plays an important function in your health - it protects you against viruses, bacteria, and other toxins that can cause disease. In autoinflammatory diseases, however, the immune system goes awry, causing unprovoked and dangerous inflammation.

New ‘molecular clock’ provides more accurate method of dating ancient human migration

Researchers at the University of Leeds have devised a more accurate method of dating ancient human migration - even when no corroborating archaeological evidence exists.

Skin cells provide new knowledge about brain functions

Until now diseases like schizophrenia and bipolar disorder have been difficult to study biologically, since this would entail taking samples from the patient's brain.

Research sheds new light on how bird flu outbreaks begin in wild bird populations

New data on the persistence of avian influenza viruses in the environment has allowed a team of University of Georgia researchers to create the first model that takes into account both direct and indirect transmission of the viruses among birds. The model, which is detailed in the early online edition of the journal Proceedings of the National Academy of Sciences, has the potential to shed new light on how outbreaks begin in wild bird populations.

Discovery of new arenavirus associated with hemorrhagic fever – first identified in nearly four decades

Scientists at Columbia University's Mailman School of Public Health, the South African National Institute for Communicable Diseases of National Health Laboratory Service (NICD-NHLS), the U.S. Centers for Disease Control and Prevention, and Roche's 454 Life Sciences Corporation have discovered the new virus responsible for a highly fatal hemorrhagic fever outbreak in Zambia and South Africa in late 2008.

Scientists create pig stem cells

Scientists have managed to induce cells from pigs to transform into pluripotent stem cells - cells that, like embryonic stem cells, are capable of developing into any type of cell in the body. It is the first time in the world that this has been achieved using somatic cells (cells that are not sperm or egg cells) from any animal with hooves (known as ungulates).

Researchers examine 'invading' bacteria in DNA - advanced warfare on the most elemental of levels

Researchers at Texas A&M University's Artie McFerrin Department of Chemical Engineering have discovered how certain types of bacteria integrate the DNA that they have captured from invading enemies into their own genetic makeup to increase their chances of survival.

Discovery of enzyme involved in inflammatory bowel disease

Researchers at Penn State College of Medicine, working with biochemists, geneticists and clinicians at the University of Bern, Switzerland and in the United Kingdom, have discovered an enzyme that has a key role in inflammatory bowel disease (IBD).

Linking microRNAs with cells that regulate the immune system could lead to new disease therapies

Linking genetic material microRNAs with cells that regulate the immune system could one day lead to new therapies for treating cancer, infections and autoimmune diseases, according to a Henry Ford Hospital study.

Discovery of gene that regulates tumors in neuroblastoma

Virginia Commonwealth University researchers have identified a gene that may play a key role in regulating tumor progression in neuroblastoma, a form of cancer usually found in young children. Scientists hope the finding could lead to an effective therapy to inhibit the expression of this gene.

Eye cancer patients want genetic testing to predict metastasis risk

If you had cancer and a genetic test could predict the risk of the tumor spreading aggressively, would you want to know - even if no treatments existed to help you?

Rapamycin epilepsy-prevention effect may be widely applicable

A drug with potential to prevent epilepsy caused by a genetic condition may also help prevent more common forms of epilepsy caused by brain injury, according to researchers at Washington University School of Medicine in St. Louis.
