New research identifies gene important for nicotine's effects on the brain

New research identifies an important gene that influences several aspects of nicotine-induced behaviors in the brain. The study, funded by National Institutes of Drug Abuse, was presented today at the American College of Neuropsychopharmacology's Annual Meeting. Investig...

Pregnancy hormone key to repairing nerve cell damage

... new myelin in the adult brain and spinal cord and identifies prolactin as a potential therapeutic substance for future testing in people with MS. "Agents promoting remyelination will be beneficial not only for typical demyelinating diseases like MS," says Dr. Fred (Rusty) Gage, of the Salk Institute, "but ...

Speeding 'fingertip' discovery -- 20 years of protein info in 1 place

...s into small fragments, separates them by size and identifies the fragments based on their mass - their size and weight. The process improves on previous techniques by breaking up proteins more gently and keeping chemical modifications like phosphorylation intact. Previous spectrometry methods were “just too ro...

Researchers hot on the trail of brain cell degeneration

...sly toxic level of over-stimulation. The study identifies a new factor provoking cell degeneration. It is more than likely that future research will uncover more such factors interacting with each other. Investigating these will benefit new forms of treatment and advance research that aims to alleviate symp...

Scientists discover a new risk factor for Alzheimer's

...racking. The importance of this work is that it identifies a new player among the mechanisms causing Alzheimer's disease, St George-Hyslop said. "This will lead to the real endgame, which is to see how to exploit the findings as a new diagnostic or therapeutic target," he said. ...

Gene expression test reveals ER and HER-2 status of breast tumors

...d and validated a new genomic microarray test that identifies whether a tumor's growth is fueled by the female hormone estrogen and the role of a growth factor receptor known as HER-2 that makes a tumor vulnerable to a specific drug. The status of these factors is now determined by pathology tests. "This is ...

Inflammation may play role in metastasis of prostate cancer

...9 in advance of publication in the journal Nature, identifies a mechanism which triggers metastasis, which is the spread of cancer in late stages of prostate cancer development. The findings by Michael Karin, Ph.D., professor of pharmacology in UCSD's Laboratory of Gene Regulation and Signal Transduction, and c...

Researchers find hepatitis A and hepatitis C attack same protein to block immune defenses

...eedings of the National Academy of Sciences. "This identifies the protein ?called MAVS, for mitochondrial antiviral signaling protein ?as extremely important for the survival of any virus in the liver." MAVS proteins project from tiny structures called mitochondria, which are found in large numbers in each l...

Rapid, Low-Cost DNA Testing

...g's innovative procedure quickly and inexpensively identifies genetic sequences in any sample of DNA. he technology is a novel fluorescent DNA screening assay, which rapidly determines whether specific DNA target sequences are present in an analyte. In simple terms, the analyte contains the DNA target sequence...

Anxiety disorders surprisingly common yet often untreated

... seven-question, self-administered screening tool, identifies patients with undiagnosed generalized anxiety disorder, panic disorder, post traumatic stress disorder or social anxiety disorder. The new study, which looked at 965 patients in 15 primary care clinics, found anxiety to be as prevalent as depression,...

Gene elevating breast cancer risk also causes prostate cancer

...gets. It could also lead to genetic screening that identifies individuals at increased breast cancer risk and result in improved prevention efforts and treatment. About a year ago, Dr Bing Xia and Professor David Livingston at the Dana-Farber Cancer Institute in Boston identified a novel BRCA2 binding factor, ...

Brown cancer biologists identify major player in cell growth

... of cancer cells is unchecked growth, the research identifies potential targets for new treatments. "As a scientist and a physician, I am tremendously excited," said Alan Rosmarin, M.D., an associate professor in the Department of Medicine and the Department of Molecular Biology, Cell Biology and Biochemistr...

New report: Explosive growth changes salmon industry

...ildlife Fund and IUCN-the World Conservation Union identifies two important trends that have remade the salmon industry in the last 25 years: farmed salmon has grown from just two percent of the world supply in 1980 to 65 percent in 2004. About three-fourths of the fresh and frozen salmon consumed in the Unite...

New bacteria test could improve quality of fruit and vegetable juice

... Lin's technique is significant because it identifies the organism quickly ?in a matter of hours, unlike traditional culturing methods, which are time consuming and require five to seven days to process. Lin said that testing time is critical for juice processing companies, which monitor for the bacteri...

Master regulatory gene of epithelial stem cells identified

...ool published in the May 4 issue of Cell, however, identifies a "master regulator" of this regeneration process not only for skin, but for many epithelial tissues including breast, prostate, and urogenital tract. This master regulator of epithelial stem cells turns out to be the p63 gene, a close relative to th...

Study shows big power of small RNAs, not just proteins, in halting cancer

...his latest research published June 6 by Nature now identifies miRNAs as a critical force behind the anti-proliferation potential of p53. Expression of most miRNAs is reduced in tumors, suggesting that some miRNAs act to prevent tumor formation. By comparing levels of miRNAs in cells with a variety of pre...

Researchers discover inherited mutation for leukemia

...n research and the new field of epigenetics, which identifies genes silenced by faulty DNA methylation, says Christoph Plass, professor of molecular virology, immunology and medical genetics and of veterinary biosciences, and also co-principal investigator on the study. "Our findings show that it's importan...
