An international group of scientists has identified three genetic regions that predispose Asian women who have never smoked to lung cancer. The finding provides further evidence that risk of lung cancer among never-smokers, especially Asian women, may be associated with certain unique inherited genetic characteristics that distinguishes it from lung cancer in smokers.

Gene therapy can be performed safely in the human salivary gland, according to scientists at the National Institute of Dental and Craniofacial Research (NIDCR), part of the National Institutes of Health. This finding comes from the first-ever safety, or Phase I, clinical study of gene therapy in a human salivary gland. Its results, published this week in the Proceedings of the National Academy of Sciences, also show that the transferred gene, Aquaporin-1, has great potential to help head and neck cancer survivors who battle with chronic dry mouth.

National Institutes of Health (NIH) researchers have discovered a significant new mechanism of action for a class of chemotherapy drugs known as poly (ADP-ribose) polymerase inhibitors, or PARP inhibitors. They have also identified differences in the toxic capabilities of three drugs in this class which are currently being tested in clinical trials.

The world's largest, most detailed catalog of human genetic variation — used by disease researchers around the world — has more than doubled in size with the 1000 Genomes Project's latest publication in the Oct. 31 issue of Nature. The National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, helps fund and direct this international public-private consortium of researchers in the United States, Britain, China, Germany and Canada.

Serous endometrial tumors account for some of the most difficult to treat cancers of the uterine lining
Researchers have identified several genes that are linked to one of the most lethal forms of uterine cancer, serous endometrial cancer. The researchers describe how three of the genes found in the study are frequently altered in the disease, suggesting that the genes drive the development of tumors.

NIH research shows exercise as key in reducing body fat while preserving muscle
Exercise and healthy eating reduce body fat and preserve muscle in adults better than diet alone, according to a study funded and conducted by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of the National Institutes of Health.

A bacterial protein in common house dust may worsen allergic responses to indoor allergens, according to research conducted by the National Institutes of Health and Duke University. The finding is the first to document the presence of the protein flagellin in house dust, bolstering the link between allergic asthma and the environment.

Andrew Holmes, Ph.D., chief of the Laboratory of Behavioral and Genomic Neuroscience at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health, has been selected as the 2012 recipient of the Jacob P. Waletzky Award from the Society for Neuroscience. The $25,000 prize is given in recognition of innovative research into substance abuse and the brain and nervous system.
