Researchers from the Department of Chemistry and Molecular Biology at the University of Gothenburg have managed for the first time to obtain detailed information about the role of the protein metastasin in the spread of tumor cells. Published recently in the renowned Proceedings of the National Academy of Sciences (PNAS), the study paves the way for the development of new drugs. Metastasin is a protein with a key role in the spread of tumor cells. Previous research has shown that it is...

Fruit flies offer insights on aging Scientists from the Florida campus of The Scripps Research Institute have shown in animal models that the loss of memory that comes with aging is not necessarily a permanent thing. In a new study published this week in an advance, online edition of the journal Proceedings of the National Academy of Sciences, Ron Davis, chair of the Department of Neuroscience at Scripps Florida, and Ayako Tonoki-Yamaguchi, a research associate in Davis's lab, took a...

What do changes in weather and stressed-out birds have to do with your health? In a study in Proceedings of the National Academy of Sciences, Jeffry Shaman of Columbia University and Marc Lipsitch of Harvard University are beginning to see a new link between La Niña conditions and outbreaks of the flu that could help governments and public health officials determine when the next pandemic will strike. To examine the connection between La Niña and flu...

The study shows that the lack of Mitofusin 2 in mice produces insulin resistance and glucose intolerance, the main causes of diabetes. Researchers at the Institute for Research in Biomedicine (IRB Barcelona) have discovered that deficiency of a single protein, Mitofusin 2, in muscle and hepatic cells of mice is sufficient to cause tissues to become insensitive to insulin, thus producing an increase in blood glucose concentrations. These are the two most common conditions prior to...

Researchers identify the novel expression of an ion channel in neurons of the brain Research at the University of Calgary's Hotchkiss Brain Institute (HBI) has demonstrated the novel expression of an ion channel in Purkinje cells — specialized neurons in the cerebellum, the area of the brain responsible for movement. Ray W. Turner, PhD, Professor in the Department of Cell Biology & Anatomy and PhD student Jordan Engbers and colleagues published this finding in the January edition...

Scans reveal how genes alter circuit hub to shape temperament -- NIH study A personality profile marked by overly gregarious yet anxious behavior is rooted in abnormal development of a circuit hub buried deep in the front center of the brain, say scientists at the National Institutes of Health. They used three different types of brain imaging to pinpoint the suspect brain area in people with Williams syndrome, a rare genetic disorder characterized by these behaviors. Matching the scans to...

Cap and trade programs to reduce emissions do not inherently provide incentives to induce the private sector to develop innovative technologies to address climate change, according to a new study in the journal Proceedings of the National Academy of Sciences. In fact, said author Margaret Taylor, a researcher at Lawrence Berkeley National Laboratory (Berkeley Lab) who conducted the study while an assistant professor at the University of California, Berkeley's Goldman School of Public...

Scientists have identified a new compound that rapidly kills hepatocellular carcinoma (HCC) cells, the most common form of liver cancer and fifth most common cancer worldwide, while sparing healthy tissue. The compound, Factor Qunolinone Inhibitor 1 (FQI1), works by inhibiting an oncogene originally discovered by a team of researchers led by Devanand Sarkar, M.B.B.S., Ph.D., Harrison Scholar at Virginia Commonwealth University (VCU) Massey Cancer Center, Blick Scholar and assistant professor...

Army scientists have demonstrated, for the first time, that antibody-based therapies can successfully protect monkeys from the deadly Ebola and Marburg viruses. In addition, the animals were fully protected even when treatment was administered two days post-infection, an accomplishment unmatched by any experimental therapy for these viruses to date. The work appears in this week's electronic edition of Proceedings of the National Academy of Sciences. The filoviruses, Ebola and Marburg,...
