New York University biologists have discovered new mechanisms that control how proteins are expressed in different regions of embryos, while also shedding additional insight into how physical traits are arranged in body plans. The researchers investigated a specific theory–morphogen theory, which posits that proteins controlling traits are arranged as gradients, with different amounts of proteins activating genes to create specified physical features. This theory was first put forth...

Protein design is technique that is increasingly valuable to a variety of fields, from biochemistry to therapeutics to materials engineering. University of Pennsylvania chemists have taken this kind of design a step further; using computational methods, they have created the first custom-designed protein crystal. Picking an ambitious design target with challenging features, the researchers´ success bodes well for the technique´s use in better understanding proteins´ makeup...

University of California, San Diego scientists have used powerful computational tools and laboratory tests to discover new support for a once-marginalized theory about the underlying cause of Parkinson´s disease. The new results conflict with an older theory that insoluble intracellular fibrils called amyloids cause Parkinson´s disease and other neurodegenerative diseases. Instead, the new findings provide a step-by-step explanation of how a “protein-run-amok”...

An international team of researchers has reported a new understanding of a little-known process that happens in virtually every cell of our bodies. Protein folding is the process by which not-yet folded chains of amino acids assume their specific shapes, hence taking on their specific functions. These functions vary widely: In the human body, proteins fold to become muscles, hormones, enzymes, and various other components. "This protein folding process is still a big mystery," said UC...

Tiny pores, or channels, embedded in cell membranes are critical to the healthy functioning of cells. Charged atoms, or ions, move through these channels to generate the electrical signals that allow cells to communicate with one another. New research at Washington University School of Medicine in St. Louis unveils some of the inner workings of certain channels involved in regulating electrical signals in nerve cells, relaxing muscle cells and “tuning” hair cells in the inner...

University of Illinois scientists report that soy protein may significantly reduce fat accumulation and triglycerides in the livers of obese persons. And they've discovered why it happens: soy restores partial function of that organ's key signaling pathway. "Almost a third of American adults have fatty liver disease, many of them without symptoms. Obesity is a key risk factor for this condition, which can lead to liver failure," said Hong Chen, a U of I assistant professor of food science...

By developing software that uses 3-D models of proteins involved in cystic fibrosis, a team of scientists at Duke University has identified several new molecules that may ease the symptoms of the disease. Computer algorithms created by the team predict how well a given molecular structure will block a basic protein-protein interaction known to occur in cystic fibrosis. To test the predictions, the scientists synthesized the molecules and measured how well they attached to one of the...

Light of specific wavelengths can be used to boost an enzyme's function by as much as 30 fold, potentially establishing a path to less expensive biofuels, detergents and a host of other products. In a paper published in The Journal of Physical Chemistry Letters, a team led by Pratul Agarwal of the Department of Energy's Oak Ridge National Laboratory described a process that aims to improve upon nature - and it happens in the blink of an eye. "When light enters the eye and hits the...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
