New research in the FASEB Journals demonstrates that blocking the delta opioid receptor in mice created resistance to weight gain and stimulated gene expression promoting non-shivering thermogenesis Imagine eating all of the sugar and fat that you want without gaining a pound. Thanks to new research published in The FASEB Journal (http://www.fasebj.org), the day may come when this is not too far from reality. That's because researchers from the United States and Europe have found that...

The research provides insights into programmed cell death and opens door to new approaches to cancer treatment Scientists at The Scripps Research Institute have simultaneously mapped two of the most important types of protein-modification in cells, revealing their extensive cooperation during an essential cellular process. Phosphorylation, the attachment of a phosphate group to a protein, and proteolysis, the cleavage of a protein, had almost always been studied independently. The new...

NEW YORK, July 13, 2012 /PRNewswire/ -- Foods can affect our moods chemically in regards to alertness and our emotional states. In his forthcoming book entitled Stress Pandemic, lifestyle and stress expert Paul Huljich shares a simple and holistic approach to nutrition, paying added attention to the effects of what we eat on our neurochemistry. "Ensuring that we are supporting a healthy neurochemical balance is a vital and proactive step toward managing our stress", Mr. Huljich asserts....

℠Traffic policeman´ protein directs crucial step in cell division A traffic policeman standing at a busy intersection directing the flow of vehicles may be a rare sight these days, but a similar scene appears to still frequently play out in our cells. A protein called Lem4 directs a crucial step of cell division by preventing the progress of one molecule while waving another through, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have...

Scientists have identified a new mechanism of bacterial pathogenesis. The results of the research project, partly funded by the Academy of Finland, have been published in the journal Proceedings of the National Academy of Sciences of the United States of America (PNAS). Bacteria that cause chronic infections have an amazing but yet poorly known ability to subvert immune response, live and produce offspring, enter and wake up from a dormant phase to cause, in some instances, deadly...

Protein binds to growth factor receptor, priming it for normal function; Likely tie to 4 cancers Once considered merely a passive link between proteins that matter, Grb2 - pronounced "grab2" - actually lives up to its nickname with its controlling grip on an important cell signaling pathway, scientists at The University of Texas MD Anderson Cancer Center report in the June 22 issue of Cell. "Grb2 is a switch that controls normal signaling through the fibroblast growth factor receptor...

Researchers at the University of California, San Diego School of Medicine have uncovered a new signal transduction pathway specifically devoted to the regulation of alternative RNA splicing, a process that allows a single gene to produce or code multiple types of protein variants. The discovery, published in the June 27, 2012 issue of Molecular Cell, suggests the new pathway might be a fruitful target for new cancer drugs. Signal transduction in the cell involves kinases and phosphatases,...

Scientists have developed a small-molecule-inhibiting drug that in early laboratory cell tests stopped breast cancer cells from spreading and also promoted the growth of early nerve cells called neurites. Researchers from Cincinnati Children's Hospital Medical Center report their findings online June 21 in Chemistry & Biology. The scientists named their lead drug candidate "Rhosin" and hope future testing shows it to be promising for the treatment of various cancers or nervous system...

International collaboration puts molecular face on enzyme family that allows plants to adjust quickly to herbivore attack or changes in growing conditions Science has known about plant hormones since Charles Darwin experimented with plant shoots and showed that the shoots bend toward the light as long as their tips, which are secreting a growth hormone, aren´t cut off. But it is only recently that scientists have begun to put a molecular face on the biochemical systems that...
